5 Changes between 0.9.6h and 0.9.7 [XX xxx 2002]
7 *) Change the declaration of needed Kerberos libraries to use EX_LIBS
8 instead of the special (and badly supported) LIBKRB5. LIBKRB5 is
12 *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it
13 seems that in spite of existing for more than a year, many application
14 author have done nothing to provide the necessary callbacks, which
15 means that this particular engine will not work properly anywhere.
16 This is a very unfortunate situation which forces us, in the name
17 of usability, to give the hw_ncipher.c a static lock, which is part
19 NOTE: This is for the 0.9.7 series ONLY. This hack will never
20 appear in 0.9.8 or later. We EXPECT application authors to have
21 dealt properly with this when 0.9.8 is released (unless we actually
22 make such changes in the libcrypto locking code that changes will
23 have to be made anyway).
26 *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
27 octets have been read, EOF or an error occurs. Without this change
28 some truncated ASN1 structures will not produce an error.
31 *) Disable Heimdal support, since it hasn't been fully implemented.
32 Still give the possibility to force the use of Heimdal, but with
33 warnings and a request that patches get sent to openssl-dev.
36 *) Add the VC-CE target, introduce the WINCE sysname, and add
37 INSTALL.WCE and appropriate conditionals to make it build.
38 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
40 *) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and
41 cygssl-x.y.z.dll, where x, y and z are the major, minor and
42 edit numbers of the version.
43 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
45 *) Introduce safe string copy and catenation functions
46 (BUF_strlcpy() and BUF_strlcat()).
47 [Ben Laurie (CHATS) and Richard Levitte]
49 *) Avoid using fixed-size buffers for one-line DNs.
52 *) Add BUF_MEM_grow_clean() to avoid information leakage when
53 resizing buffers containing secrets, and use where appropriate.
56 *) Avoid using fixed size buffers for configuration file location.
59 *) Avoid filename truncation for various CA files.
62 *) Use sizeof in preference to magic numbers.
65 *) Avoid filename truncation in cert requests.
68 *) Add assertions to check for (supposedly impossible) buffer
72 *) Don't cache truncated DNS entries in the local cache (this could
73 potentially lead to a spoofing attack).
76 *) Fix various buffers to be large enough for hex/decimal
77 representations in a platform independent manner.
80 *) Add CRYPTO_realloc_clean() to avoid information leakage when
81 resizing buffers containing secrets, and use where appropriate.
84 *) Add BIO_indent() to avoid much slightly worrying code to do
88 *) Convert sprintf()/BIO_puts() to BIO_printf().
91 *) buffer_gets() could terminate with the buffer only half
95 *) Add assertions to prevent user-supplied crypto functions from
96 overflowing internal buffers by having large block sizes, etc.
99 *) New OPENSSL_assert() macro (similar to assert(), but enabled
103 *) Eliminate unused copy of key in RC4.
106 *) Eliminate unused and incorrectly sized buffers for IV in pem.h.
109 *) Fix off-by-one error in EGD path.
112 *) If RANDFILE path is too long, ignore instead of truncating.
115 *) Eliminate unused and incorrectly sized X.509 structure
119 *) Eliminate unused and dangerous function knumber().
122 *) Eliminate unused and dangerous structure, KSSL_ERR.
125 *) Protect against overlong session ID context length in an encoded
126 session object. Since these are local, this does not appear to be
130 *) Change from security patch (see 0.9.6e below) that did not affect
131 the 0.9.6 release series:
133 Remote buffer overflow in SSL3 protocol - an attacker could
134 supply an oversized master key in Kerberos-enabled versions.
138 *) Change the SSL kerb5 codes to match RFC 2712.
141 *) Make -nameopt work fully for req and add -reqopt switch.
142 [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
144 *) The "block size" for block ciphers in CFB and OFB mode should be 1.
145 [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
147 *) Make sure tests can be performed even if the corresponding algorithms
148 have been removed entirely. This was also the last step to make
149 OpenSSL compilable with DJGPP under all reasonable conditions.
150 [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
152 *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
153 to allow version independent disabling of normally unselected ciphers,
154 which may be activated as a side-effect of selecting a single cipher.
156 (E.g., cipher list string "RSA" enables ciphersuites that are left
157 out of "ALL" because they do not provide symmetric encryption.
158 "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
159 [Lutz Jaenicke, Bodo Moeller]
161 *) Add appropriate support for separate platform-dependent build
162 directories. The recommended way to make a platform-dependent
163 build directory is the following (tested on Linux), maybe with
166 # Place yourself outside of the OpenSSL source tree. In
167 # this example, the environment variable OPENSSL_SOURCE
168 # is assumed to contain the absolute OpenSSL source directory.
169 mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
170 cd objtree/"`uname -s`-`uname -r`-`uname -m`"
171 (cd $OPENSSL_SOURCE; find . -type f -o -type l) | while read F; do
172 mkdir -p `dirname $F`
173 ln -s $OPENSSL_SOURCE/$F $F
176 To be absolutely sure not to disturb the source tree, a "make clean"
177 is a good thing. If it isn't successfull, don't worry about it,
178 it probably means the source directory is very clean.
181 *) Make sure any ENGINE control commands make local copies of string
182 pointers passed to them whenever necessary. Otherwise it is possible
183 the caller may have overwritten (or deallocated) the original string
184 data when a later ENGINE operation tries to use the stored values.
185 [Götz Babin-Ebell <babinebell@trustcenter.de>]
187 *) Improve diagnostics in file reading and command-line digests.
188 [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
190 *) Add AES modes CFB and OFB to the object database. Correct an
191 error in AES-CFB decryption.
194 *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
195 allows existing EVP_CIPHER_CTX structures to be reused after
196 calling EVP_*Final(). This behaviour is used by encryption
197 BIOs and some applications. This has the side effect that
198 applications must explicitly clean up cipher contexts with
199 EVP_CIPHER_CTX_cleanup() or they will leak memory.
202 *) Check the values of dna and dnb in bn_mul_recursive before calling
203 bn_mul_comba (a non zero value means the a or b arrays do not contain
204 n2 elements) and fallback to bn_mul_normal if either is not zero.
207 *) Fix escaping of non-ASCII characters when using the -subj option
208 of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
211 *) Make object definitions compliant to LDAP (RFC2256): SN is the short
212 form for "surname", serialNumber has no short form.
213 Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
214 therefore remove "mail" short name for "internet 7".
215 The OID for unique identifiers in X509 certificates is
216 x500UniqueIdentifier, not uniqueIdentifier.
217 Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
220 *) Add an "init" command to the ENGINE config module and auto initialize
221 ENGINEs. Without any "init" command the ENGINE will be initialized
222 after all ctrl commands have been executed on it. If init=1 the
223 ENGINE is initailized at that point (ctrls before that point are run
224 on the uninitialized ENGINE and after on the initialized one). If
225 init=0 then the ENGINE will not be iniatialized at all.
228 *) Fix the 'app_verify_callback' interface so that the user-defined
229 argument is actually passed to the callback: In the
230 SSL_CTX_set_cert_verify_callback() prototype, the callback
231 declaration has been changed from
234 int (*cb)(X509_STORE_CTX *,void *);
235 in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
236 i=s->ctx->app_verify_callback(&ctx)
237 has been changed into
238 i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
240 To update applications using SSL_CTX_set_cert_verify_callback(),
241 a dummy argument can be added to their callback functions.
242 [D. K. Smetters <smetters@parc.xerox.com>]
244 *) Added the '4758cca' ENGINE to support IBM 4758 cards.
245 [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
247 *) Add and OPENSSL_LOAD_CONF define which will cause
248 OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
249 This allows older applications to transparently support certain
250 OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
251 Two new functions OPENSSL_add_all_algorithms_noconf() which will never
252 load the config file and OPENSSL_add_all_algorithms_conf() which will
253 always load it have also been added.
256 *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
257 Adjust NIDs and EVP layer.
258 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
260 *) Config modules support in openssl utility.
262 Most commands now load modules from the config file,
263 though in a few (such as version) this isn't done
264 because it couldn't be used for anything.
266 In the case of ca and req the config file used is
267 the same as the utility itself: that is the -config
268 command line option can be used to specify an
272 *) Move default behaviour from OPENSSL_config(). If appname is NULL
273 use "openssl_conf" if filename is NULL use default openssl config file.
276 *) Add an argument to OPENSSL_config() to allow the use of an alternative
277 config section name. Add a new flag to tolerate a missing config file
278 and move code to CONF_modules_load_file().
281 *) Support for crypto accelerator cards from Accelerated Encryption
282 Processing, www.aep.ie. (Use engine 'aep')
283 The support was copied from 0.9.6c [engine] and adapted/corrected
284 to work with the new engine framework.
285 [AEP Inc. and Richard Levitte]
287 *) Support for SureWare crypto accelerator cards from Baltimore
288 Technologies. (Use engine 'sureware')
289 The support was copied from 0.9.6c [engine] and adapted
290 to work with the new engine framework.
293 *) Have the CHIL engine fork-safe (as defined by nCipher) and actually
294 make the newer ENGINE framework commands for the CHIL engine work.
295 [Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
297 *) Make it possible to produce shared libraries on ReliantUNIX.
298 [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
300 *) Add the configuration target debug-linux-ppro.
301 Make 'openssl rsa' use the general key loading routines
302 implemented in apps.c, and make those routines able to
303 handle the key format FORMAT_NETSCAPE and the variant
305 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
307 *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
308 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
310 *) Add -keyform to rsautl, and document -engine.
311 [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
313 *) Change BIO_new_file (crypto/bio/bss_file.c) to use new
314 BIO_R_NO_SUCH_FILE error code rather than the generic
315 ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
320 ERR_peek_last_error_line
321 ERR_peek_last_error_line_data.
325 ERR_peek_error_line_data,
326 but report on the latest error recorded rather than the first one
327 still in the error queue.
328 [Ben Laurie, Bodo Moeller]
330 *) default_algorithms option in ENGINE config module. This allows things
332 default_algorithms = ALL
333 default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
336 *) Prelminary ENGINE config module.
339 *) New experimental application configuration code.
342 *) Change the AES code to follow the same name structure as all other
343 symmetric ciphers, and behave the same way. Move everything to
344 the directory crypto/aes, thereby obsoleting crypto/rijndael.
345 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
347 *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
348 [Ben Laurie and Theo de Raadt]
350 *) Add option to output public keys in req command.
351 [Massimiliano Pala madwolf@openca.org]
353 *) Use wNAFs in EC_POINTs_mul() for improved efficiency
354 (up to about 10% better than before for P-192 and P-224).
357 *) New functions/macros
359 SSL_CTX_set_msg_callback(ctx, cb)
360 SSL_CTX_set_msg_callback_arg(ctx, arg)
361 SSL_set_msg_callback(ssl, cb)
362 SSL_set_msg_callback_arg(ssl, arg)
364 to request calling a callback function
366 void cb(int write_p, int version, int content_type,
367 const void *buf, size_t len, SSL *ssl, void *arg)
369 whenever a protocol message has been completely received
370 (write_p == 0) or sent (write_p == 1). Here 'version' is the
371 protocol version according to which the SSL library interprets
372 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
373 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
374 the content type as defined in the SSL 3.0/TLS 1.0 protocol
375 specification (change_cipher_spec(20), alert(21), handshake(22)).
376 'buf' and 'len' point to the actual message, 'ssl' to the
377 SSL object, and 'arg' is the application-defined value set by
378 SSL[_CTX]_set_msg_callback_arg().
380 'openssl s_client' and 'openssl s_server' have new '-msg' options
381 to enable a callback that displays all protocol messages.
384 *) Change the shared library support so shared libraries are built as
385 soon as the corresponding static library is finished, and thereby get
386 openssl and the test programs linked against the shared library.
387 This still only happens when the keyword "shard" has been given to
388 the configuration scripts.
390 NOTE: shared library support is still an experimental thing, and
391 backward binary compatibility is still not guaranteed.
392 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
394 *) Add support for Subject Information Access extension.
395 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
397 *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
398 additional bytes when new memory had to be allocated, not just
399 when reusing an existing buffer.
402 *) New command line and configuration option 'utf8' for the req command.
403 This allows field values to be specified as UTF8 strings.
406 *) Add -multi and -mr options to "openssl speed" - giving multiple parallel
407 runs for the former and machine-readable output for the latter.
410 *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
411 of the e-mail address in the DN (i.e., it will go into a certificate
412 extension only). The new configuration file option 'email_in_dn = no'
414 [Massimiliano Pala madwolf@openca.org]
416 *) Change all functions with names starting with des_ to be starting
417 with DES_ instead. Add wrappers that are compatible with libdes,
418 but are named _ossl_old_des_*. Finally, add macros that map the
419 des_* symbols to the corresponding _ossl_old_des_* if libdes
420 compatibility is desired. If OpenSSL 0.9.6c compatibility is
421 desired, the des_* symbols will be mapped to DES_*, with one
424 Since we provide two compatibility mappings, the user needs to
425 define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
426 compatibility is desired. The default (i.e., when that macro
427 isn't defined) is OpenSSL 0.9.6c compatibility.
429 There are also macros that enable and disable the support of old
430 des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
431 and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
432 are defined, the default will apply: to support the old des routines.
434 In either case, one must include openssl/des.h to get the correct
435 definitions. Do not try to just include openssl/des_old.h, that
438 NOTE: This is a major break of an old API into a new one. Software
439 authors are encouraged to switch to the DES_ style functions. Some
440 time in the future, des_old.h and the libdes compatibility functions
441 will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the
442 default), and then completely removed.
445 *) Test for certificates which contain unsupported critical extensions.
446 If such a certificate is found during a verify operation it is
447 rejected by default: this behaviour can be overridden by either
448 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
449 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
450 X509_supported_extension() has also been added which returns 1 if a
451 particular extension is supported.
454 *) Modify the behaviour of EVP cipher functions in similar way to digests
455 to retain compatibility with existing code.
458 *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
459 compatibility with existing code. In particular the 'ctx' parameter does
460 not have to be to be initialized before the call to EVP_DigestInit() and
461 it is tidied up after a call to EVP_DigestFinal(). New function
462 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
463 EVP_MD_CTX_copy() changed to not require the destination to be
464 initialized valid and new function EVP_MD_CTX_copy_ex() added which
465 requires the destination to be valid.
467 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
468 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
471 *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
472 so that complete 'Handshake' protocol structures are kept in memory
473 instead of overwriting 'msg_type' and 'length' with 'body' data.
476 *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
477 [Massimo Santin via Richard Levitte]
479 *) Major restructuring to the underlying ENGINE code. This includes
480 reduction of linker bloat, separation of pure "ENGINE" manipulation
481 (initialisation, etc) from functionality dealing with implementations
482 of specific crypto iterfaces. This change also introduces integrated
483 support for symmetric ciphers and digest implementations - so ENGINEs
484 can now accelerate these by providing EVP_CIPHER and EVP_MD
485 implementations of their own. This is detailed in crypto/engine/README
486 as it couldn't be adequately described here. However, there are a few
487 API changes worth noting - some RSA, DSA, DH, and RAND functions that
488 were changed in the original introduction of ENGINE code have now
489 reverted back - the hooking from this code to ENGINE is now a good
490 deal more passive and at run-time, operations deal directly with
491 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
492 dereferencing through an ENGINE pointer any more. Also, the ENGINE
493 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
494 they were not being used by the framework as there is no concept of a
495 BIGNUM_METHOD and they could not be generalised to the new
496 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
497 ENGINE_cpy() has been removed as it cannot be consistently defined in
501 *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
504 *) Change mkdef.pl to sort symbols that get the same entry number,
505 and make sure the automatically generated functions ERR_load_*
506 become part of libeay.num as well.
509 *) New function SSL_renegotiate_pending(). This returns true once
510 renegotiation has been requested (either SSL_renegotiate() call
511 or HelloRequest/ClientHello receveived from the peer) and becomes
512 false once a handshake has been completed.
513 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
514 sends a HelloRequest, but does not ensure that a handshake takes
515 place. SSL_renegotiate_pending() is useful for checking if the
516 client has followed the request.)
519 *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
520 By default, clients may request session resumption even during
521 renegotiation (if session ID contexts permit); with this option,
522 session resumption is possible only in the first handshake.
524 SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
525 more bits available for options that should not be part of
526 SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
529 *) Add some demos for certificate and certificate request creation.
532 *) Make maximum certificate chain size accepted from the peer application
533 settable (SSL*_get/set_max_cert_list()), as proposed by
534 "Douglas E. Engert" <deengert@anl.gov>.
537 *) Add support for shared libraries for Unixware-7
538 (Boyd Lynn Gerber <gerberb@zenez.com>).
541 *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
542 be done prior to destruction. Use this to unload error strings from
543 ENGINEs that load their own error strings. NB: This adds two new API
544 functions to "get" and "set" this destroy handler in an ENGINE.
547 *) Alter all existing ENGINE implementations (except "openssl" and
548 "openbsd") to dynamically instantiate their own error strings. This
549 makes them more flexible to be built both as statically-linked ENGINEs
550 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
551 Also, add stub code to each that makes building them as self-contained
552 shared-libraries easier (see README.ENGINE).
555 *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
556 implementations into applications that are completely implemented in
557 self-contained shared-libraries. The "dynamic" ENGINE exposes control
558 commands that can be used to configure what shared-library to load and
559 to control aspects of the way it is handled. Also, made an update to
560 the README.ENGINE file that brings its information up-to-date and
561 provides some information and instructions on the "dynamic" ENGINE
562 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
565 *) Make it possible to unload ranges of ERR strings with a new
566 "ERR_unload_strings" function.
569 *) Add a copy() function to EVP_MD.
572 *) Make EVP_MD routines take a context pointer instead of just the
573 md_data void pointer.
576 *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
577 that the digest can only process a single chunk of data
578 (typically because it is provided by a piece of
579 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
580 is only going to provide a single chunk of data, and hence the
581 framework needn't accumulate the data for oneshot drivers.
584 *) As with "ERR", make it possible to replace the underlying "ex_data"
585 functions. This change also alters the storage and management of global
586 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
587 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
588 index counters. The API functions that use this state have been changed
589 to take a "class_index" rather than pointers to the class's local STACK
590 and counter, and there is now an API function to dynamically create new
591 classes. This centralisation allows us to (a) plug a lot of the
592 thread-safety problems that existed, and (b) makes it possible to clean
593 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
594 such data would previously have always leaked in application code and
595 workarounds were in place to make the memory debugging turn a blind eye
596 to it. Application code that doesn't use this new function will still
597 leak as before, but their memory debugging output will announce it now
598 rather than letting it slide.
600 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
601 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
602 has a return value to indicate success or failure.
605 *) Make it possible to replace the underlying "ERR" functions such that the
606 global state (2 LHASH tables and 2 locks) is only used by the "default"
607 implementation. This change also adds two functions to "get" and "set"
608 the implementation prior to it being automatically set the first time
609 any other ERR function takes place. Ie. an application can call "get",
610 pass the return value to a module it has just loaded, and that module
611 can call its own "set" function using that value. This means the
612 module's "ERR" operations will use (and modify) the error state in the
613 application and not in its own statically linked copy of OpenSSL code.
616 *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
617 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
618 the operation, and provides a more encapsulated way for external code
619 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
620 to use these functions rather than manually incrementing the counts.
622 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
625 *) Add EVP test program.
628 *) Add symmetric cipher support to ENGINE. Expect the API to change!
631 *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
632 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
633 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
634 These allow a CRL to be built without having to access X509_CRL fields
635 directly. Modify 'ca' application to use new functions.
638 *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
639 bug workarounds. Rollback attack detection is a security feature.
640 The problem will only arise on OpenSSL servers when TLSv1 is not
641 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
642 Software authors not wanting to support TLSv1 will have special reasons
643 for their choice and can explicitly enable this option.
644 [Bodo Moeller, Lutz Jaenicke]
646 *) Rationalise EVP so it can be extended: don't include a union of
647 cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
648 (similar to those existing for EVP_CIPHER_CTX).
653 EVP_MD_CTX_init(&md); /* new function call */
654 EVP_DigestInit(&md, EVP_sha1());
655 EVP_DigestUpdate(&md, in, len);
656 EVP_DigestFinal(&md, out, NULL);
657 EVP_MD_CTX_cleanup(&md); /* new function call */
661 *) Make DES key schedule conform to the usual scheme, as well as
662 correcting its structure. This means that calls to DES functions
663 now have to pass a pointer to a des_key_schedule instead of a
664 plain des_key_schedule (which was actually always a pointer
669 des_set_key_checked(..., &ks);
670 des_ncbc_encrypt(..., &ks, ...);
672 (Note that a later change renames 'des_...' into 'DES_...'.)
675 *) Initial reduction of linker bloat: the use of some functions, such as
676 PEM causes large amounts of unused functions to be linked in due to
677 poor organisation. For example pem_all.c contains every PEM function
678 which has a knock on effect of linking in large amounts of (unused)
679 ASN1 code. Grouping together similar functions and splitting unrelated
680 functions prevents this.
683 *) Cleanup of EVP macros.
686 *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
690 *) Add initial OCSP responder support to ocsp application. The
691 revocation information is handled using the text based index
692 use by the ca application. The responder can either handle
693 requests generated internally, supplied in files (for example
694 via a CGI script) or using an internal minimal server.
697 *) Add configuration choices to get zlib compression for TLS.
700 *) Changes to Kerberos SSL for RFC 2712 compliance:
701 1. Implemented real KerberosWrapper, instead of just using
702 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
703 2. Implemented optional authenticator field of KerberosWrapper.
705 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
706 and authenticator structs; see crypto/krb5/.
708 Generalized Kerberos calls to support multiple Kerberos libraries.
709 [Vern Staats <staatsvr@asc.hpc.mil>,
710 Jeffrey Altman <jaltman@columbia.edu>
713 *) Cause 'openssl speed' to use fully hard-coded DSA keys as it
714 already does with RSA. testdsa.h now has 'priv_key/pub_key'
715 values for each of the key sizes rather than having just
716 parameters (and 'speed' generating keys each time).
719 *) Speed up EVP routines.
722 type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes

737 *) Added the OS2-EMX target.
738 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
740 *) Rewrite apps to use NCONF routines instead of the old CONF. New functions
741 to support NCONF routines in extension code. New function CONF_set_nconf()
742 to allow functions which take an NCONF to also handle the old LHASH
743 structure: this means that the old CONF compatible routines can be
744 retained (in particular wrt extensions) without having to duplicate the
745 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
748 *) Enhance the general user interface with mechanisms for inner control
749 and with possibilities to have yes/no kind of prompts.
752 *) Change all calls to low level digest routines in the library and
753 applications to use EVP. Add missing calls to HMAC_cleanup() and
754 don't assume HMAC_CTX can be copied using memcpy().
755 [Verdon Walker <VWalker@novell.com>, Steve Henson]
757 *) Add the possibility to control engines through control names but with
758 arbitrary arguments instead of just a string.
759 Change the key loaders to take a UI_METHOD instead of a callback
760 function pointer. NOTE: this breaks binary compatibility with earlier
761 versions of OpenSSL [engine].
762 Adapt the nCipher code for these new conditions and add a card insertion
766 *) Enhance the general user interface with mechanisms to better support
767 dialog box interfaces, application-defined prompts, the possibility
768 to use defaults (for example default passwords from somewhere else)
769 and interrupts/cancellations.
772 *) Tidy up PKCS#12 attribute handling. Add support for the CSP name
773 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
776 *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
777 tidy up some unnecessarily weird code in 'sk_new()').
778 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
780 *) Change the key loading routines for ENGINEs to use the same kind
781 callback (pem_password_cb) as all other routines that need this
785 *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
786 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
787 than this minimum value is recommended.
790 *) New random seeder for OpenVMS, using the system process statistics
791 that are easily reachable.
794 *) Windows apparently can't transparently handle global
795 variables defined in DLLs. Initialisations such as:
797 const ASN1_ITEM *it = &ASN1_INTEGER_it;
799 wont compile. This is used by the any applications that need to
800 declare their own ASN1 modules. This was fixed by adding the option
801 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
802 needed for static libraries under Win32.
805 *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
806 setting of purpose and trust fields. New X509_STORE trust and
807 purpose functions and tidy up setting in other SSL functions.
810 *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
811 structure. These are inherited by X509_STORE_CTX when it is
812 initialised. This allows various defaults to be set in the
813 X509_STORE structure (such as flags for CRL checking and custom
814 purpose or trust settings) for functions which only use X509_STORE_CTX
815 internally such as S/MIME.
817 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
818 trust settings if they are not set in X509_STORE. This allows X509_STORE
819 purposes and trust (in S/MIME for example) to override any set by default.
821 Add command line options for CRL checking to smime, s_client and s_server
825 *) Initial CRL based revocation checking. If the CRL checking flag(s)
826 are set then the CRL is looked up in the X509_STORE structure and
827 its validity and signature checked, then if the certificate is found
828 in the CRL the verify fails with a revoked error.
830 Various new CRL related callbacks added to X509_STORE_CTX structure.
832 Command line options added to 'verify' application to support this.
834 This needs some additional work, such as being able to handle multiple
835 CRLs with different times, extension based lookup (rather than just
836 by subject name) and ultimately more complete V2 CRL extension
840 *) Add a general user interface API (crypto/ui/). This is designed
841 to replace things like des_read_password and friends (backward
842 compatibility functions using this new API are provided).
843 The purpose is to remove prompting functions from the DES code
844 section as well as provide for prompting through dialog boxes in
845 a window system and the like.
848 *) Add "ex_data" support to ENGINE so implementations can add state at a
849 per-structure level rather than having to store it globally.
852 *) Make it possible for ENGINE structures to be copied when retrieved by
853 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
854 This causes the "original" ENGINE structure to act like a template,
855 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
856 operational state can be localised to each ENGINE structure, despite the
857 fact they all share the same "methods". New ENGINE structures returned in
858 this case have no functional references and the return value is the single
859 structural reference. This matches the single structural reference returned
860 by ENGINE_by_id() normally, when it is incremented on the pre-existing
864 *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
865 needs to match any other type at all we need to manually clear the
869 *) Changes to the "openssl engine" utility to include;
870 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
871 about an ENGINE's available control commands.
872 - executing control commands from command line arguments using the
873 '-pre' and '-post' switches. '-post' is only used if '-t' is
874 specified and the ENGINE is successfully initialised. The syntax for
875 the individual commands are colon-separated, for example;
876 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
879 *) New dynamic control command support for ENGINEs. ENGINEs can now
880 declare their own commands (numbers), names (strings), descriptions,
881 and input types for run-time discovery by calling applications. A
882 subset of these commands are implicitly classed as "executable"
883 depending on their input type, and only these can be invoked through
884 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
885 can be based on user input, config files, etc). The distinction is
886 that "executable" commands cannot return anything other than a boolean
887 result and can only support numeric or string input, whereas some
888 discoverable commands may only be for direct use through
889 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
890 pointers, or other custom uses. The "executable" commands are to
891 support parameterisations of ENGINE behaviour that can be
892 unambiguously defined by ENGINEs and used consistently across any
893 OpenSSL-based application. Commands have been added to all the
894 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
895 control over shared-library paths without source code alterations.
898 *) Changed all ENGINE implementations to dynamically allocate their
899 ENGINEs rather than declaring them statically. Apart from this being
900 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
901 this also allows the implementations to compile without using the
902 internal engine_int.h header.
905 *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
906 'const' value. Any code that should be able to modify a RAND_METHOD
907 should already have non-const pointers to it (ie. they should only
908 modify their own ones).
911 *) Made a variety of little tweaks to the ENGINE code.
912 - "atalla" and "ubsec" string definitions were moved from header files
913 to C code. "nuron" string definitions were placed in variables
914 rather than hard-coded - allowing parameterisation of these values
915 later on via ctrl() commands.
916 - Removed unused "#if 0"'d code.
917 - Fixed engine list iteration code so it uses ENGINE_free() to release
918 structural references.
919 - Constified the RAND_METHOD element of ENGINE structures.
920 - Constified various get/set functions as appropriate and added
921 missing functions (including a catch-all ENGINE_cpy that duplicates
922 all ENGINE values onto a new ENGINE except reference counts/state).
923 - Removed NULL parameter checks in get/set functions. Setting a method
924 or function to NULL is a way of cancelling out a previously set
925 value. Passing a NULL ENGINE parameter is just plain stupid anyway
926 and doesn't justify the extra error symbols and code.
927 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
928 flags from engine_int.h to engine.h.
929 - Changed prototypes for ENGINE handler functions (init(), finish(),
930 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
933 *) Implement binary inversion algorithm for BN_mod_inverse in addition
934 to the algorithm using long division. The binary algorithm can be
935 used only if the modulus is odd. On 32-bit systems, it is faster
936 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
937 roughly 5-15% for 256-bit moduli), so we use it only for moduli
938 up to 450 bits. In 64-bit environments, the binary algorithm
939 appears to be advantageous for much longer moduli; here we use it
940 for moduli up to 2048 bits.
943 *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
944 could not support the combine flag in choice fields.
947 *) Add a 'copy_extensions' option to the 'ca' utility. This copies
948 extensions from a certificate request to the certificate.
951 *) Allow multiple 'certopt' and 'nameopt' options to be separated
952 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
953 file: this allows the display of the certificate about to be
954 signed to be customised, to allow certain fields to be included
955 or excluded and extension details. The old system didn't display
956 multicharacter strings properly, omitted fields not in the policy
957 and couldn't display additional details such as extensions.
960 *) Function EC_POINTs_mul for multiple scalar multiplication
961 of an arbitrary number of elliptic curve points
962 \sum scalars[i]*points[i],
963 optionally including the generator defined for the EC_GROUP:
964 scalar*generator + \sum scalars[i]*points[i].
966 EC_POINT_mul is a simple wrapper function for the typical case
967 that the point list has just one item (besides the optional
971 *) First EC_METHODs for curves over GF(p):
973 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
974 operations and provides various method functions that can also
975 operate with faster implementations of modular arithmetic.
977 EC_GFp_mont_method() reuses most functions that are part of
978 EC_GFp_simple_method, but uses Montgomery arithmetic.
980 [Bodo Moeller; point addition and point doubling
981 implementation directly derived from source code provided by
982 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
984 *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
987 Curves are EC_GROUP objects (with an optional group generator)
988 based on EC_METHODs that are built into the library.
990 Points are EC_POINT objects based on EC_GROUP objects.
992 Most of the framework would be able to handle curves over arbitrary
993 finite fields, but as there are no obvious types for fields other
994 than GF(p), some functions are limited to that for now.
997 *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
998 that the file contains a complete HTTP response.
1001 *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
1002 change the def and num file printf format specifier from "%-40sXXX"
1003 to "%-39s XXX". The latter will always guarantee a space after the
1004 field while the former will cause them to run together if the field
1005 is 40 of more characters long.
1008 *) Constify the cipher and digest 'method' functions and structures
1009 and modify related functions to take constant EVP_MD and EVP_CIPHER
1013 *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
1014 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
1017 *) Modify EVP_Digest*() routines so they now return values. Although the
1018 internal software routines can never fail additional hardware versions
1022 *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
1024 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
1025 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
1028 ERR_R_NESTED_ASN1_ERROR
1030 ERR_R_MISSING_ASN1_EOS
1031 were 4 .. 9, conflicting with
1032 ERR_LIB_RSA (= ERR_R_RSA_LIB)
1034 ERR_LIB_PEM (= ERR_R_PEM_LIB).
1035 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
1037 Add new error code 'ERR_R_INTERNAL_ERROR'.
1040 *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
1044 *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
1045 sets the subject name for a new request or supersedes the
1046 subject name in a given request. Formats that can be parsed are
1047 'CN=Some Name, OU=myOU, C=IT'
1049 'CN=Some Name/OU=myOU/C=IT'.
1051 Add options '-batch' and '-verbose' to 'openssl req'.
1052 [Massimiliano Pala <madwolf@hackmasters.net>]
1054 *) Introduce the possibility to access global variables through
1055 functions on platform were that's the best way to handle exporting
1056 global variables in shared libraries. To enable this functionality,
1057 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
1058 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
1059 is normally done by Configure or something similar).
1061 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
1062 in the source file (foo.c) like this:
1064 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
1065 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
1067 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
1068 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
1070 OPENSSL_DECLARE_GLOBAL(int,foo);
1071 #define foo OPENSSL_GLOBAL_REF(foo)
1072 OPENSSL_DECLARE_GLOBAL(double,bar);
1073 #define bar OPENSSL_GLOBAL_REF(bar)
1075 The #defines are very important, and therefore so is including the
1076 header file everywhere where the defined globals are used.
1078 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
1079 of ASN.1 items, but that structure is a bit different.
1081 The largest change is in util/mkdef.pl which has been enhanced with
1082 better and easier to understand logic to choose which symbols should
1083 go into the Windows .def files as well as a number of fixes and code
1084 cleanup (among others, algorithm keywords are now sorted
1085 lexicographically to avoid constant rewrites).
1088 *) In BN_div() keep a copy of the sign of 'num' before writing the
1089 result to 'rm' because if rm==num the value will be overwritten
1090 and produce the wrong result if 'num' is negative: this caused
1091 problems with BN_mod() and BN_nnmod().
1094 *) Function OCSP_request_verify(). This checks the signature on an
1095 OCSP request and verifies the signer certificate. The signer
1096 certificate is just checked for a generic purpose and OCSP request
1100 *) Add OCSP_check_validity() function to check the validity of OCSP
1101 responses. OCSP responses are prepared in real time and may only
1102 be a few seconds old. Simply checking that the current time lies
1103 between thisUpdate and nextUpdate max reject otherwise valid responses
1104 caused by either OCSP responder or client clock inaccuracy. Instead
1105 we allow thisUpdate and nextUpdate to fall within a certain period of
1106 the current time. The age of the response can also optionally be
1107 checked. Two new options -validity_period and -status_age added to
1111 *) If signature or public key algorithm is unrecognized print out its
1112 OID rather that just UNKNOWN.
1115 *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
1116 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
1117 ID to be generated from the issuer certificate alone which can then be
1118 passed to OCSP_id_issuer_cmp().
1121 *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
1122 ASN1 modules to export functions returning ASN1_ITEM pointers
1123 instead of the ASN1_ITEM structures themselves. This adds several
1124 new macros which allow the underlying ASN1 function/structure to
1125 be accessed transparently. As a result code should not use ASN1_ITEM
1126 references directly (such as &X509_it) but instead use the relevant
1127 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
1128 use of the new ASN1 code on platforms where exporting structures
1129 is problematical (for example in shared libraries) but exporting
1130 functions returning pointers to structures is not.
1133 *) Add support for overriding the generation of SSL/TLS session IDs.
1134 These callbacks can be registered either in an SSL_CTX or per SSL.
1135 The purpose of this is to allow applications to control, if they wish,
1136 the arbitrary values chosen for use as session IDs, particularly as it
1137 can be useful for session caching in multiple-server environments. A
1138 command-line switch for testing this (and any client code that wishes
1139 to use such a feature) has been added to "s_server".
1140 [Geoff Thorpe, Lutz Jaenicke]
1142 *) Modify mkdef.pl to recognise and parse preprocessor conditionals
1143 of the form '#if defined(...) || defined(...) || ...' and
1144 '#if !defined(...) && !defined(...) && ...'. This also avoids
1145 the growing number of special cases it was previously handling.
1148 *) Make all configuration macros available for application by making
1149 sure they are available in opensslconf.h, by giving them names starting
1150 with "OPENSSL_" to avoid conflicts with other packages and by making
1151 sure e_os2.h will cover all platform-specific cases together with
1153 Additionally, it is now possible to define configuration/platform-
1154 specific names (called "system identities"). In the C code, these
1155 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
1156 macro with the name beginning with "OPENSSL_SYS_", which is determined
1157 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
1161 *) New option -set_serial to 'req' and 'x509' this allows the serial
1162 number to use to be specified on the command line. Previously self
1163 signed certificates were hard coded with serial number 0 and the
1164 CA options of 'x509' had to use a serial number in a file which was
1168 *) New options to 'ca' utility to support V2 CRL entry extensions.
1169 Currently CRL reason, invalidity date and hold instruction are
1170 supported. Add new CRL extensions to V3 code and some new objects.
1173 *) New function EVP_CIPHER_CTX_set_padding() this is used to
1174 disable standard block padding (aka PKCS#5 padding) in the EVP
1175 API, which was previously mandatory. This means that the data is
1176 not padded in any way and so the total length much be a multiple
1177 of the block size, otherwise an error occurs.
1180 *) Initial (incomplete) OCSP SSL support.
1183 *) New function OCSP_parse_url(). This splits up a URL into its host,
1184 port and path components: primarily to parse OCSP URLs. New -url
1185 option to ocsp utility.
1188 *) New nonce behavior. The return value of OCSP_check_nonce() now
1189 reflects the various checks performed. Applications can decide
1190 whether to tolerate certain situations such as an absent nonce
1191 in a response when one was present in a request: the ocsp application
1192 just prints out a warning. New function OCSP_add1_basic_nonce()
1193 this is to allow responders to include a nonce in a response even if
1194 the request is nonce-less.
1197 *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
1198 skipped when using openssl x509 multiple times on a single input file,
1199 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
1202 *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
1203 set string type: to handle setting ASN1_TIME structures. Fix ca
1204 utility to correctly initialize revocation date of CRLs.
1207 *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
1208 the clients preferred ciphersuites and rather use its own preferences.
1209 Should help to work around M$ SGC (Server Gated Cryptography) bug in
1210 Internet Explorer by ensuring unchanged hash method during stepup.
1211 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
1214 *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
1215 to aes and add a new 'exist' option to print out symbols that don't
1219 *) Additional options to ocsp utility to allow flags to be set and
1220 additional certificates supplied.
1223 *) Add the option -VAfile to 'openssl ocsp', so the user can give the
1224 OCSP client a number of certificate to only verify the response
1228 *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
1229 handle the new API. Currently only ECB, CBC modes supported. Add new
1232 Add TLS AES ciphersuites as described in RFC3268, "Advanced
1233 Encryption Standard (AES) Ciphersuites for Transport Layer
1234 Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
1235 not enabled by default and were not part of the "ALL" ciphersuite
1236 alias because they were not yet official; they could be
1237 explicitly requested by specifying the "AESdraft" ciphersuite
1238 group alias. In the final release of OpenSSL 0.9.7, the group
1239 alias is called "AES" and is part of "ALL".)
1240 [Ben Laurie, Steve Henson, Bodo Moeller]
1242 *) New function OCSP_copy_nonce() to copy nonce value (if present) from
1243 request to response.
1246 *) Functions for OCSP responders. OCSP_request_onereq_count(),
1247 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
1248 extract information from a certificate request. OCSP_response_create()
1249 creates a response and optionally adds a basic response structure.
1250 OCSP_basic_add1_status() adds a complete single response to a basic
1251 response and returns the OCSP_SINGLERESP structure just added (to allow
1252 extensions to be included for example). OCSP_basic_add1_cert() adds a
1253 certificate to a basic response and OCSP_basic_sign() signs a basic
1254 response with various flags. New helper functions ASN1_TIME_check()
1255 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
1256 (converts ASN1_TIME to GeneralizedTime).
1259 *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
1260 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
1261 structure from a certificate. X509_pubkey_digest() digests the public_key
1262 contents: this is used in various key identifiers.
1265 *) Make sk_sort() tolerate a NULL argument.
1266 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
1268 *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
1269 passed by the function are trusted implicitly. If any of them signed the
1270 response then it is assumed to be valid and is not verified.
1273 *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
1274 to data. This was previously part of the PKCS7 ASN1 code. This
1275 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
1276 [Steve Henson, reported by Kenneth R. Robinette
1277 <support@securenetterm.com>]
1279 *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
1280 routines: without these tracing memory leaks is very painful.
1281 Fix leaks in PKCS12 and PKCS7 routines.
1284 *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
1285 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
1286 effectively meant GeneralizedTime would never be used. Now it
1287 is initialised to -1 but X509_time_adj() now has to check the value
1288 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
1289 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
1290 [Steve Henson, reported by Kenneth R. Robinette
1291 <support@securenetterm.com>]
1293 *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
1294 result in a zero length in the ASN1_INTEGER structure which was
1295 not consistent with the structure when d2i_ASN1_INTEGER() was used
1296 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
1297 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
1298 where it did not print out a minus for negative ASN1_INTEGER.
1301 *) Add summary printout to ocsp utility. The various functions which
1302 convert status values to strings have been renamed to:
1303 OCSP_response_status_str(), OCSP_cert_status_str() and
1304 OCSP_crl_reason_str() and are no longer static. New options
1305 to verify nonce values and to disable verification. OCSP response
1306 printout format cleaned up.
1309 *) Add additional OCSP certificate checks. These are those specified
1310 in RFC2560. This consists of two separate checks: the CA of the
1311 certificate being checked must either be the OCSP signer certificate
1312 or the issuer of the OCSP signer certificate. In the latter case the
1313 OCSP signer certificate must contain the OCSP signing extended key
1314 usage. This check is performed by attempting to match the OCSP
1315 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
1316 in the OCSP_CERTID structures of the response.
1319 *) Initial OCSP certificate verification added to OCSP_basic_verify()
1320 and related routines. This uses the standard OpenSSL certificate
1321 verify routines to perform initial checks (just CA validity) and
1322 to obtain the certificate chain. Then additional checks will be
1323 performed on the chain. Currently the root CA is checked to see
1324 if it is explicitly trusted for OCSP signing. This is used to set
1325 a root CA as a global signing root: that is any certificate that
1326 chains to that CA is an acceptable OCSP signing certificate.
1329 *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
1330 extensions from a separate configuration file.
1331 As when reading extensions from the main configuration file,
1332 the '-extensions ...' option may be used for specifying the
1334 [Massimiliano Pala <madwolf@comune.modena.it>]
1336 *) New OCSP utility. Allows OCSP requests to be generated or
1337 read. The request can be sent to a responder and the output
1338 parsed, outputed or printed in text form. Not complete yet:
1339 still needs to check the OCSP response validity.
1342 *) New subcommands for 'openssl ca':
1343 'openssl ca -status <serial>' prints the status of the cert with
1344 the given serial number (according to the index file).
1345 'openssl ca -updatedb' updates the expiry status of certificates
1347 [Massimiliano Pala <madwolf@comune.modena.it>]
1349 *) New '-newreq-nodes' command option to CA.pl. This is like
1350 '-newreq', but calls 'openssl req' with the '-nodes' option
1351 so that the resulting key is not encrypted.
1352 [Damien Miller <djm@mindrot.org>]
1354 *) New configuration for the GNU Hurd.
1355 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
1357 *) Initial code to implement OCSP basic response verify. This
1358 is currently incomplete. Currently just finds the signer's
1359 certificate and verifies the signature on the response.
1362 *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
1363 value of OPENSSLDIR. This is available via the new '-d' option
1364 to 'openssl version', and is also included in 'openssl version -a'.
1367 *) Allowing defining memory allocation callbacks that will be given
1368 file name and line number information in additional arguments
1369 (a const char* and an int). The basic functionality remains, as
1370 well as the original possibility to just replace malloc(),
1371 realloc() and free() by functions that do not know about these
1372 additional arguments. To register and find out the current
1373 settings for extended allocation functions, the following
1374 functions are provided:
1376 CRYPTO_set_mem_ex_functions
1377 CRYPTO_set_locked_mem_ex_functions
1378 CRYPTO_get_mem_ex_functions
1379 CRYPTO_get_locked_mem_ex_functions
1381 These work the same way as CRYPTO_set_mem_functions and friends.
1382 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
1383 extended allocation function is enabled.
1384 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
1385 a conventional allocation function is enabled.
1386 [Richard Levitte, Bodo Moeller]
1388 *) Finish off removing the remaining LHASH function pointer casts.
1389 There should no longer be any prototype-casting required when using
1390 the LHASH abstraction, and any casts that remain are "bugs". See
1391 the callback types and macros at the head of lhash.h for details
1392 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
1395 *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
1396 If /dev/[u]random devices are not available or do not return enough
1397 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
1399 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
1400 /etc/entropy will be queried once each in this sequence, quering stops
1401 when enough entropy was collected without querying more sockets.
1404 *) Change the Unix RAND_poll() variant to be able to poll several
1405 random devices, as specified by DEVRANDOM, until a sufficient amount
1406 of data has been collected. We spend at most 10 ms on each file
1407 (select timeout) and read in non-blocking mode. DEVRANDOM now
1408 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
1409 (previously it was just the string "/dev/urandom"), so on typical
1410 platforms the 10 ms delay will never occur.
1411 Also separate out the Unix variant to its own file, rand_unix.c.
1412 For VMS, there's a currently-empty rand_vms.c.
1415 *) Move OCSP client related routines to ocsp_cl.c. These
1416 provide utility functions which an application needing
1417 to issue a request to an OCSP responder and analyse the
1418 response will typically need: as opposed to those which an
1419 OCSP responder itself would need which will be added later.
1421 OCSP_request_sign() signs an OCSP request with an API similar
1422 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
1423 response. OCSP_response_get1_basic() extracts basic response
1424 from response. OCSP_resp_find_status(): finds and extracts status
1425 information from an OCSP_CERTID structure (which will be created
1426 when the request structure is built). These are built from lower
1427 level functions which work on OCSP_SINGLERESP structures but
1428 wont normally be used unless the application wishes to examine
1429 extensions in the OCSP response for example.
1431 Replace nonce routines with a pair of functions.
1432 OCSP_request_add1_nonce() adds a nonce value and optionally
1433 generates a random value. OCSP_check_nonce() checks the
1434 validity of the nonce in an OCSP response.
1437 *) Change function OCSP_request_add() to OCSP_request_add0_id().
1438 This doesn't copy the supplied OCSP_CERTID and avoids the
1439 need to free up the newly created id. Change return type
1440 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
1441 This can then be used to add extensions to the request.
1442 Deleted OCSP_request_new(), since most of its functionality
1443 is now in OCSP_REQUEST_new() (and the case insensitive name
1444 clash) apart from the ability to set the request name which
1445 will be added elsewhere.
1448 *) Update OCSP API. Remove obsolete extensions argument from
1449 various functions. Extensions are now handled using the new
1450 OCSP extension code. New simple OCSP HTTP function which
1451 can be used to send requests and parse the response.
1454 *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
1455 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
1456 uses the special reorder version of SET OF to sort the attributes
1457 and reorder them to match the encoded order. This resolves a long
1458 standing problem: a verify on a PKCS7 structure just after signing
1459 it used to fail because the attribute order did not match the
1460 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
1461 it uses the received order. This is necessary to tolerate some broken
1462 software that does not order SET OF. This is handled by encoding
1463 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
1464 to produce the required SET OF.
1467 *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
1468 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
1469 files to get correct declarations of the ASN.1 item variables.
1472 *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
1473 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
1474 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
1475 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
1476 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
1477 ASN1_ITEM and no wrapper functions.
1480 *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
1481 replace the old function pointer based I/O routines. Change most of
1482 the *_d2i_bio() and *_d2i_fp() functions to use these.
1485 *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
1486 lines, recognice more "algorithms" that can be deselected, and make
1487 it complain about algorithm deselection that isn't recognised.
1490 *) New ASN1 functions to handle dup, sign, verify, digest, pack and
1491 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
1492 to use new functions. Add NO_ASN1_OLD which can be set to remove
1493 some old style ASN1 functions: this can be used to determine if old
1494 code will still work when these eventually go away.
1497 *) New extension functions for OCSP structures, these follow the
1498 same conventions as certificates and CRLs.
1501 *) New function X509V3_add1_i2d(). This automatically encodes and
1502 adds an extension. Its behaviour can be customised with various
1503 flags to append, replace or delete. Various wrappers added for
1504 certifcates and CRLs.
1507 *) Fix to avoid calling the underlying ASN1 print routine when
1508 an extension cannot be parsed. Correct a typo in the
1509 OCSP_SERVICELOC extension. Tidy up print OCSP format.
1512 *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
1513 entries for variables.
1516 *) Add functionality to apps/openssl.c for detecting locking
1517 problems: As the program is single-threaded, all we have
1518 to do is register a locking callback using an array for
1519 storing which locks are currently held by the program.
1522 *) Use a lock around the call to CRYPTO_get_ex_new_index() in
1523 SSL_get_ex_data_X509_STORE_idx(), which is used in
1524 ssl_verify_cert_chain() and thus can be called at any time
1525 during TLS/SSL handshakes so that thread-safety is essential.
1526 Unfortunately, the ex_data design is not at all suited
1527 for multi-threaded use, so it probably should be abolished.
1530 *) Added Broadcom "ubsec" ENGINE to OpenSSL.
1531 [Broadcom, tweaked and integrated by Geoff Thorpe]
1533 *) Move common extension printing code to new function
1534 X509V3_print_extensions(). Reorganise OCSP print routines and
1535 implement some needed OCSP ASN1 functions. Add OCSP extensions.
1538 *) New function X509_signature_print() to remove duplication in some
1542 *) Add a special meaning when SET OF and SEQUENCE OF flags are both
1543 set (this was treated exactly the same as SET OF previously). This
1544 is used to reorder the STACK representing the structure to match the
1545 encoding. This will be used to get round a problem where a PKCS7
1546 structure which was signed could not be verified because the STACK
1547 order did not reflect the encoded order.
1550 *) Reimplement the OCSP ASN1 module using the new code.
1553 *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
1554 for its ASN1 operations. The old style function pointers still exist
1555 for now but they will eventually go away.
1558 *) Merge in replacement ASN1 code from the ASN1 branch. This almost
1559 completely replaces the old ASN1 functionality with a table driven
1560 encoder and decoder which interprets an ASN1_ITEM structure describing
1561 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
1562 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
1563 has also been converted to the new form.
1566 *) Change BN_mod_exp_recp so that negative moduli are tolerated
1567 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
1568 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
1569 for negative moduli.
1572 *) Fix BN_uadd and BN_usub: Always return non-negative results instead
1573 of not touching the result's sign bit.
1576 *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
1580 *) Changed the LHASH code to use prototypes for callbacks, and created
1581 macros to declare and implement thin (optionally static) functions
1582 that provide type-safety and avoid function pointer casting for the
1583 type-specific callbacks.
1586 *) Added Kerberos Cipher Suites to be used with TLS, as written in
1588 [Veers Staats <staatsvr@asc.hpc.mil>,
1589 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
1591 *) Reformat the FAQ so the different questions and answers can be divided
1592 in sections depending on the subject.
1595 *) Have the zlib compression code load ZLIB.DLL dynamically under
1599 *) New function BN_mod_sqrt for computing square roots modulo a prime
1600 (using the probabilistic Tonelli-Shanks algorithm unless
1601 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
1602 be handled deterministically).
1603 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1605 *) Make BN_mod_inverse faster by explicitly handling small quotients
1606 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
1607 512 bits], about 30% for larger ones [1024 or 2048 bits].)
1610 *) New function BN_kronecker.
1613 *) Fix BN_gcd so that it works on negative inputs; the result is
1614 positive unless both parameters are zero.
1615 Previously something reasonably close to an infinite loop was
1616 possible because numbers could be growing instead of shrinking
1617 in the implementation of Euclid's algorithm.
1620 *) Fix BN_is_word() and BN_is_one() macros to take into account the
1621 sign of the number in question.
1623 Fix BN_is_word(a,w) to work correctly for w == 0.
1625 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
1626 because its test if the absolute value of 'a' equals 'w'.
1627 Note that BN_abs_is_word does *not* handle w == 0 reliably;
1628 it exists mostly for use in the implementations of BN_is_zero(),
1629 BN_is_one(), and BN_is_word().
1632 *) New function BN_swap.
1635 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
1636 the exponentiation functions are more likely to produce reasonable
1637 results on negative inputs.
1640 *) Change BN_mod_mul so that the result is always non-negative.
1641 Previously, it could be negative if one of the factors was negative;
1642 I don't think anyone really wanted that behaviour.
1645 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
1646 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
1647 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
1648 and add new functions:
1657 BN_mod_lshift1_quick
1661 These functions always generate non-negative results.
1663 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
1664 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
1666 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
1667 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
1668 be reduced modulo m.
1669 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1671 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
1672 was actually never needed) and in BN_mul(). The removal in BN_mul()
1673 required a small change in bn_mul_part_recursive() and the addition
1674 of the functions bn_cmp_part_words(), bn_sub_part_words() and
1675 bn_add_part_words(), which do the same thing as bn_cmp_words(),
1676 bn_sub_words() and bn_add_words() except they take arrays with
1680 *) In 'openssl passwd', verify passwords read from the terminal
1681 unless the '-salt' option is used (which usually means that
1682 verification would just waste user's time since the resulting
1683 hash is going to be compared with some given password hash)
1684 or the new '-noverify' option is used.
1686 This is an incompatible change, but it does not affect
1687 non-interactive use of 'openssl passwd' (passwords on the command
1688 line, '-stdin' option, '-in ...' option) and thus should not
1692 *) Remove all references to RSAref, since there's no more need for it.
1695 *) Make DSO load along a path given through an environment variable
1696 (SHLIB_PATH) with shl_load().
1699 *) Constify the ENGINE code as a result of BIGNUM constification.
1700 Also constify the RSA code and most things related to it. In a
1701 few places, most notable in the depth of the ASN.1 code, ugly
1702 casts back to non-const were required (to be solved at a later
1706 *) Make it so the openssl application has all engines loaded by default.
1709 *) Constify the BIGNUM routines a little more.
1712 *) Add the following functions:
1714 ENGINE_load_cswift()
1716 ENGINE_load_atalla()
1718 ENGINE_load_builtin_engines()
1720 That way, an application can itself choose if external engines that
1721 are built-in in OpenSSL shall ever be used or not. The benefit is
1722 that applications won't have to be linked with libdl or other dso
1723 libraries unless it's really needed.
1725 Changed 'openssl engine' to load all engines on demand.
1726 Changed the engine header files to avoid the duplication of some
1727 declarations (they differed!).
1730 *) 'openssl engine' can now list capabilities.
1733 *) Better error reporting in 'openssl engine'.
1736 *) Never call load_dh_param(NULL) in s_server.
1739 *) Add engine application. It can currently list engines by name and
1740 identity, and test if they are actually available.
1743 *) Improve RPM specification file by forcing symbolic linking and making
1744 sure the installed documentation is also owned by root.root.
1745 [Damien Miller <djm@mindrot.org>]
1747 *) Give the OpenSSL applications more possibilities to make use of
1748 keys (public as well as private) handled by engines.
1751 *) Add OCSP code that comes from CertCo.
1754 *) Add VMS support for the Rijndael code.
1757 *) Added untested support for Nuron crypto accelerator.
1760 *) Add support for external cryptographic devices. This code was
1761 previously distributed separately as the "engine" branch.
1762 [Geoff Thorpe, Richard Levitte]
1764 *) Rework the filename-translation in the DSO code. It is now possible to
1765 have far greater control over how a "name" is turned into a filename
1766 depending on the operating environment and any oddities about the
1767 different shared library filenames on each system.
1770 *) Support threads on FreeBSD-elf in Configure.
1773 *) Fix for SHA1 assembly problem with MASM: it produces
1774 warnings about corrupt line number information when assembling
1775 with debugging information. This is caused by the overlapping
1777 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
1780 NCONF_get_number() has no error checking at all. As a replacement,
1781 NCONF_get_number_e() is defined (_e for "error checking") and is
1782 promoted strongly. The old NCONF_get_number is kept around for
1783 binary backward compatibility.
1784 Make it possible for methods to load from something other than a BIO,
1785 by providing a function pointer that is given a name instead of a BIO.
1786 For example, this could be used to load configuration data from an
1790 *) Fix for non blocking accept BIOs. Added new I/O special reason
1791 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
1792 with non blocking I/O was not possible because no retry code was
1793 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
1797 *) Added the beginnings of Rijndael support.
1800 *) Fix for bug in DirectoryString mask setting. Add support for
1801 X509_NAME_print_ex() in 'req' and X509_print_ex() function
1802 to allow certificate printing to more controllable, additional
1803 'certopt' option to 'x509' to allow new printing options to be
1807 *) Clean old EAY MD5 hack from e_os.h.
1810 Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
1812 *) New function OPENSSL_cleanse(), which is used to cleanse a section of
1813 memory from it's contents. This is done with a counter that will
1814 place alternating values in each byte. This can be used to solve
1815 two issues: 1) the removal of calls to memset() by highly optimizing
1816 compilers, and 2) cleansing with other values than 0, since those can
1817 be read through on certain media, for example a swap space on disk.
1820 *) Bugfix: client side session caching did not work with external caching,
1821 because the session->cipher setting was not restored when reloading
1822 from the external cache. This problem was masked, when
1823 SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
1824 (Found by Steve Haslam <steve@araqnid.ddts.net>.)
1827 *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
1828 length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
1829 [Zeev Lieber <zeev-l@yahoo.com>]
1831 *) Undo an undocumented change introduced in 0.9.6e which caused
1832 repeated calls to OpenSSL_add_all_ciphers() and
1833 OpenSSL_add_all_digests() to be ignored, even after calling
1837 *) Change the default configuration reader to deal with last line not
1838 being properly terminated.
1841 *) Change X509_NAME_cmp() so it applies the special rules on handling
1842 DN values that are of type PrintableString, as well as RDNs of type
1843 emailAddress where the value has the type ia5String.
1844 [stefank@valicert.com via Richard Levitte]
1846 *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
1847 the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
1848 doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
1849 the bitwise-OR of the two for use by the majority of applications
1850 wanting this behaviour, and update the docs. The documented
1851 behaviour and actual behaviour were inconsistent and had been
1852 changing anyway, so this is more a bug-fix than a behavioural
1854 [Geoff Thorpe, diagnosed by Nadav Har'El]
1856 *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
1857 (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
1860 *) Fix initialization code race conditions in
1861 SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
1862 SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
1863 SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),
1864 TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(),
1865 ssl2_get_cipher_by_char(),
1866 ssl3_get_cipher_by_char().
1867 [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
1869 *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
1870 the cached sessions are flushed, as the remove_cb() might use ex_data
1871 contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
1872 (see [openssl.org #212]).
1873 [Geoff Thorpe, Lutz Jaenicke]
1875 *) Fix typo in OBJ_txt2obj which incorrectly passed the content
1876 length, instead of the encoding length to d2i_ASN1_OBJECT.
1879 Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
1881 *) [In 0.9.6g-engine release:]
1882 Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
1883 [Lynn Gazis <lgazis@rainbow.com>]
1885 Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
1887 *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
1888 and get fix the header length calculation.
1889 [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
1890 Alon Kantor <alonk@checkpoint.com> (and others),
1893 *) Use proper error handling instead of 'assertions' in buffer
1894 overflow checks added in 0.9.6e. This prevents DoS (the
1895 assertions could call abort()).
1896 [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
1898 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
1900 *) Add various sanity checks to asn1_get_length() to reject
1901 the ASN1 length bytes if they exceed sizeof(long), will appear
1902 negative or the content length exceeds the length of the
1904 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
1906 *) Fix cipher selection routines: ciphers without encryption had no flags
1907 for the cipher strength set and where therefore not handled correctly
1908 by the selection routines (PR #130).
1911 *) Fix EVP_dsa_sha macro.
1915 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
1916 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
1917 that was added in OpenSSL 0.9.6d.
1919 As the countermeasure turned out to be incompatible with some
1920 broken SSL implementations, the new option is part of SSL_OP_ALL.
1921 SSL_OP_ALL is usually employed when compatibility with weird SSL
1922 implementations is desired (e.g. '-bugs' option to 's_client' and
1923 's_server'), so the new option is automatically set in many
1927 *) Changes in security patch:
1929 Changes marked "(CHATS)" were sponsored by the Defense Advanced
1930 Research Projects Agency (DARPA) and Air Force Research Laboratory,
1931 Air Force Materiel Command, USAF, under agreement number
1934 *) Add various sanity checks to asn1_get_length() to reject
1935 the ASN1 length bytes if they exceed sizeof(long), will appear
1936 negative or the content length exceeds the length of the
1937 supplied buffer. (CAN-2002-0659)
1938 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
1940 *) Assertions for various potential buffer overflows, not known to
1942 [Ben Laurie (CHATS)]
1944 *) Various temporary buffers to hold ASCII versions of integers were
1945 too small for 64 bit platforms. (CAN-2002-0655)
1946 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
1948 *) Remote buffer overflow in SSL3 protocol - an attacker could
1949 supply an oversized session ID to a client. (CAN-2002-0656)
1950 [Ben Laurie (CHATS)]
1952 *) Remote buffer overflow in SSL2 protocol - an attacker could
1953 supply an oversized client master key. (CAN-2002-0656)
1954 [Ben Laurie (CHATS)]
1956 Changes between 0.9.6c and 0.9.6d [9 May 2002]
1958 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
1959 encoded as NULL) with id-dsa-with-sha1.
1960 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
1962 *) Check various X509_...() return values in apps/req.c.
1963 [Nils Larsch <nla@trustcenter.de>]
1965 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
1966 an end-of-file condition would erronously be flagged, when the CRLF
1967 was just at the end of a processed block. The bug was discovered when
1968 processing data through a buffering memory BIO handing the data to a
1969 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
1970 <ptsekov@syntrex.com> and Nedelcho Stanev.
1973 *) Implement a countermeasure against a vulnerability recently found
1974 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
1975 before application data chunks to avoid the use of known IVs
1976 with data potentially chosen by the attacker.
1979 *) Fix length checks in ssl3_get_client_hello().
1982 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
1983 to prevent ssl3_read_internal() from incorrectly assuming that
1984 ssl3_read_bytes() found application data while handshake
1985 processing was enabled when in fact s->s3->in_read_app_data was
1986 merely automatically cleared during the initial handshake.
1987 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
1989 *) Fix object definitions for Private and Enterprise: they were not
1990 recognized in their shortname (=lowercase) representation. Extend
1991 obj_dat.pl to issue an error when using undefined keywords instead
1992 of silently ignoring the problem (Svenning Sorensen
1993 <sss@sss.dnsalias.net>).
1996 *) Fix DH_generate_parameters() so that it works for 'non-standard'
1997 generators, i.e. generators other than 2 and 5. (Previously, the
1998 code did not properly initialise the 'add' and 'rem' values to
1999 BN_generate_prime().)
2001 In the new general case, we do not insist that 'generator' is
2002 actually a primitive root: This requirement is rather pointless;
2003 a generator of the order-q subgroup is just as good, if not
2007 *) Map new X509 verification errors to alerts. Discovered and submitted by
2008 Tom Wu <tom@arcot.com>.
2011 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
2012 returning non-zero before the data has been completely received
2013 when using non-blocking I/O.
2014 [Bodo Moeller; problem pointed out by John Hughes]
2016 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
2017 [Ben Laurie, Lutz Jaenicke]
2019 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
2020 Yoram Zahavi <YoramZ@gilian.com>).
2023 *) Add information about CygWin 1.3 and on, and preserve proper
2024 configuration for the versions before that.
2025 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
2027 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
2028 check whether we deal with a copy of a session and do not delete from
2029 the cache in this case. Problem reported by "Izhar Shoshani Levi"
2030 <izhar@checkpoint.com>.
2033 *) Do not store session data into the internal session cache, if it
2034 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
2035 flag is set). Proposed by Aslam <aslam@funk.com>.
2038 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
2042 *) [In 0.9.6d-engine release:]
2043 Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
2044 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
2046 *) Add the configuration target linux-s390x.
2047 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
2049 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
2050 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
2051 variable as an indication that a ClientHello message has been
2052 received. As the flag value will be lost between multiple
2053 invocations of ssl3_accept when using non-blocking I/O, the
2054 function may not be aware that a handshake has actually taken
2055 place, thus preventing a new session from being added to the
2058 To avoid this problem, we now set s->new_session to 2 instead of
2059 using a local variable.
2060 [Lutz Jaenicke, Bodo Moeller]
2062 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
2063 if the SSL_R_LENGTH_MISMATCH error is detected.
2064 [Geoff Thorpe, Bodo Moeller]
2066 *) New 'shared_ldflag' column in Configure platform table.
2069 *) Fix EVP_CIPHER_mode macro.
2070 ["Dan S. Camper" <dan@bti.net>]
2072 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
2073 type, we must throw them away by setting rr->length to 0.
2074 [D P Chang <dpc@qualys.com>]
2076 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
2078 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
2079 <Dominikus.Scherkl@biodata.com>. (The previous implementation
2080 worked incorrectly for those cases where range = 10..._2 and
2081 3*range is two bits longer than range.)
2084 *) Only add signing time to PKCS7 structures if it is not already
2088 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
2089 OBJ_ld_ce should be OBJ_id_ce.
2090 Also some ip-pda OIDs in crypto/objects/objects.txt were
2091 incorrect (cf. RFC 3039).
2092 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
2094 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
2095 returns early because it has nothing to do.
2096 [Andy Schneider <andy.schneider@bjss.co.uk>]
2098 *) [In 0.9.6c-engine release:]
2099 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
2100 [Andy Schneider <andy.schneider@bjss.co.uk>]
2102 *) [In 0.9.6c-engine release:]
2103 Add support for Cryptographic Appliance's keyserver technology.
2104 (Use engine 'keyclient')
2105 [Cryptographic Appliances and Geoff Thorpe]
2107 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
2108 is called via tools/c89.sh because arguments have to be
2109 rearranged (all '-L' options must appear before the first object
2111 [Richard Shapiro <rshapiro@abinitio.com>]
2113 *) [In 0.9.6c-engine release:]
2114 Add support for Broadcom crypto accelerator cards, backported
2116 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
2118 *) [In 0.9.6c-engine release:]
2119 Add support for SureWare crypto accelerator cards from
2120 Baltimore Technologies. (Use engine 'sureware')
2121 [Baltimore Technologies and Mark Cox]
2123 *) [In 0.9.6c-engine release:]
2124 Add support for crypto accelerator cards from Accelerated
2125 Encryption Processing, www.aep.ie. (Use engine 'aep')
2126 [AEP Inc. and Mark Cox]
2128 *) Add a configuration entry for gcc on UnixWare.
2129 [Gary Benson <gbenson@redhat.com>]
2131 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
2132 messages are stored in a single piece (fixed-length part and
2133 variable-length part combined) and fix various bugs found on the way.
2136 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
2137 instead. BIO_gethostbyname() does not know what timeouts are
2138 appropriate, so entries would stay in cache even when they have
2140 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
2142 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
2143 faced with a pathologically small ClientHello fragment that does
2144 not contain client_version: Instead of aborting with an error,
2145 simply choose the highest available protocol version (i.e.,
2146 TLS 1.0 unless it is disabled). In practice, ClientHello
2147 messages are never sent like this, but this change gives us
2148 strictly correct behaviour at least for TLS.
2151 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
2152 never resets s->method to s->ctx->method when called from within
2153 one of the SSL handshake functions.
2154 [Bodo Moeller; problem pointed out by Niko Baric]
2156 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
2157 (sent using the client's version number) if client_version is
2158 smaller than the protocol version in use. Also change
2159 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
2160 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
2161 the client will at least see that alert.
2164 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
2168 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
2169 client receives HelloRequest while in a handshake.
2170 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
2172 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
2173 should end in 'break', not 'goto end' which circuments various
2174 cleanups done in state SSL_ST_OK. But session related stuff
2175 must be disabled for SSL_ST_OK in the case that we just sent a
2178 Also avoid some overhead by not calling ssl_init_wbio_buffer()
2179 before just sending a HelloRequest.
2180 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
2182 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
2183 reveal whether illegal block cipher padding was found or a MAC
2184 verification error occured. (Neither SSLerr() codes nor alerts
2185 are directly visible to potential attackers, but the information
2186 may leak via logfiles.)
2188 Similar changes are not required for the SSL 2.0 implementation
2189 because the number of padding bytes is sent in clear for SSL 2.0,
2190 and the extra bytes are just ignored. However ssl/s2_pkt.c
2191 failed to verify that the purported number of padding bytes is in
2195 *) Add OpenUNIX-8 support including shared libraries
2196 (Boyd Lynn Gerber <gerberb@zenez.com>).
2199 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
2200 'wristwatch attack' using huge encoding parameters (cf.
2201 James H. Manger's CRYPTO 2001 paper). Note that the
2202 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
2203 encoding parameters and hence was not vulnerable.
2206 *) BN_sqr() bug fix.
2207 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
2209 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
2210 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
2211 followed by modular reduction.
2212 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
2214 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
2215 equivalent based on BN_pseudo_rand() instead of BN_rand().
2218 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
2219 This function was broken, as the check for a new client hello message
2220 to handle SGC did not allow these large messages.
2221 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
2224 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
2227 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
2228 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
2231 *) Rework the configuration and shared library support for Tru64 Unix.
2232 The configuration part makes use of modern compiler features and
2233 still retains old compiler behavior for those that run older versions
2234 of the OS. The shared library support part includes a variant that
2235 uses the RPATH feature, and is available through the special
2236 configuration target "alpha-cc-rpath", which will never be selected
2238 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
2240 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
2241 with the same message size as in ssl3_get_certificate_request().
2242 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
2243 messages might inadvertently be reject as too long.
2244 [Petr Lampa <lampa@fee.vutbr.cz>]
2246 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
2249 *) Modified SSL library such that the verify_callback that has been set
2250 specificly for an SSL object with SSL_set_verify() is actually being
2251 used. Before the change, a verify_callback set with this function was
2252 ignored and the verify_callback() set in the SSL_CTX at the time of
2253 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
2254 to allow the necessary settings.
2257 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
2258 explicitly to NULL, as at least on Solaris 8 this seems not always to be
2259 done automatically (in contradiction to the requirements of the C
2260 standard). This made problems when used from OpenSSH.
2263 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
2264 dh->length and always used
2266 BN_rand_range(priv_key, dh->p).
2268 BN_rand_range() is not necessary for Diffie-Hellman, and this
2269 specific range makes Diffie-Hellman unnecessarily inefficient if
2270 dh->length (recommended exponent length) is much smaller than the
2271 length of dh->p. We could use BN_rand_range() if the order of
2272 the subgroup was stored in the DH structure, but we only have
2277 BN_rand(priv_key, l, ...)
2279 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
2285 RSA_eay_public_encrypt
2286 RSA_eay_private_decrypt
2287 RSA_eay_private_encrypt (signing)
2288 RSA_eay_public_decrypt (signature verification)
2290 (default implementations for RSA_public_encrypt,
2291 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
2292 always reject numbers >= n.
2295 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
2296 to synchronize access to 'locking_thread'. This is necessary on
2297 systems where access to 'locking_thread' (an 'unsigned long'
2298 variable) is not atomic.
2301 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
2302 *before* setting the 'crypto_lock_rand' flag. The previous code had
2303 a race condition if 0 is a valid thread ID.
2304 [Travis Vitek <vitek@roguewave.com>]
2306 *) Add support for shared libraries under Irix.
2307 [Albert Chin-A-Young <china@thewrittenword.com>]
2309 *) Add configuration option to build on Linux on both big-endian and
2311 [Ralf Baechle <ralf@uni-koblenz.de>]
2313 *) Add the possibility to create shared libraries on HP-UX.
2316 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
2318 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
2319 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
2320 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
2321 PRNG state recovery was possible based on the output of
2322 one PRNG request appropriately sized to gain knowledge on
2323 'md' followed by enough consecutive 1-byte PRNG requests
2324 to traverse all of 'state'.
2326 1. When updating 'md_local' (the current thread's copy of 'md')
2327 during PRNG output generation, hash all of the previous
2328 'md_local' value, not just the half used for PRNG output.
2330 2. Make the number of bytes from 'state' included into the hash
2331 independent from the number of PRNG bytes requested.
2333 The first measure alone would be sufficient to avoid
2334 Markku-Juhani's attack. (Actually it had never occurred
2335 to me that the half of 'md_local' used for chaining was the
2336 half from which PRNG output bytes were taken -- I had always
2337 assumed that the secret half would be used.) The second
2338 measure makes sure that additional data from 'state' is never
2339 mixed into 'md_local' in small portions; this heuristically
2340 further strengthens the PRNG.
2343 *) Fix crypto/bn/asm/mips3.s.
2346 *) When only the key is given to "enc", the IV is undefined. Print out
2347 an error message in this case.
2350 *) Handle special case when X509_NAME is empty in X509 printing routines.
2353 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
2354 positive and less than q.
2357 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
2358 used: it isn't thread safe and the add_lock_callback should handle
2360 [Paul Rose <Paul.Rose@bridge.com>]
2362 *) Verify that incoming data obeys the block size in
2363 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
2367 [Ulf Möller, Bodo Möller]
2369 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
2370 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
2371 when fixing the server behaviour for backwards-compatible 'client
2372 hello' messages. (Note that the attack is impractical against
2373 SSL 3.0 and TLS 1.0 anyway because length and version checking
2374 means that the probability of guessing a valid ciphertext is
2375 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
2378 Before 0.9.5, the countermeasure (hide the error by generating a
2379 random 'decryption result') did not work properly because
2380 ERR_clear_error() was missing, meaning that SSL_get_error() would
2381 detect the supposedly ignored error.
2383 Both problems are now fixed.
2386 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
2387 (previously it was 1024).
2390 *) Fix for compatibility mode trust settings: ignore trust settings
2391 unless some valid trust or reject settings are present.
2394 *) Fix for blowfish EVP: its a variable length cipher.
2397 *) Fix various bugs related to DSA S/MIME verification. Handle missing
2398 parameters in DSA public key structures and return an error in the
2399 DSA routines if parameters are absent.
2402 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
2403 in the current directory if neither $RANDFILE nor $HOME was set.
2404 RAND_file_name() in 0.9.6a returned NULL in this case. This has
2405 caused some confusion to Windows users who haven't defined $HOME.
2406 Thus RAND_file_name() is changed again: e_os.h can define a
2407 DEFAULT_HOME, which will be used if $HOME is not set.
2408 For Windows, we use "C:"; on other platforms, we still require
2409 environment variables.
2411 *) Move 'if (!initialized) RAND_poll()' into regions protected by
2412 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
2413 having multiple threads call RAND_poll() concurrently.
2416 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
2417 combination of a flag and a thread ID variable.
2418 Otherwise while one thread is in ssleay_rand_bytes (which sets the
2419 flag), *other* threads can enter ssleay_add_bytes without obeying
2420 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
2421 that they do not hold after the first thread unsets add_do_not_lock).
2424 *) Change bctest again: '-x' expressions are not available in all
2428 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
2430 *) Fix a couple of memory leaks in PKCS7_dataDecode()
2431 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
2433 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
2434 the default extension for executables, if any. Also, make the perl
2435 scripts that use symlink() to test if it really exists and use "cp"
2436 if it doesn't. All this made OpenSSL compilable and installable in
2440 *) Fix for asn1_GetSequence() for indefinite length constructed data.
2441 If SEQUENCE is length is indefinite just set c->slen to the total
2442 amount of data available.
2443 [Steve Henson, reported by shige@FreeBSD.org]
2444 [This change does not apply to 0.9.7.]
2446 *) Change bctest to avoid here-documents inside command substitution
2447 (workaround for FreeBSD /bin/sh bug).
2448 For compatibility with Ultrix, avoid shell functions (introduced
2449 in the bctest version that searches along $PATH).
2452 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
2453 with des_encrypt() defined on some operating systems, like Solaris
2457 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
2458 On the Importance of Eliminating Errors in Cryptographic
2459 Computations, J. Cryptology 14 (2001) 2, 101-119,
2460 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
2463 *) MIPS assembler BIGNUM division bug fix.
2466 *) Disabled incorrect Alpha assembler code.
2469 *) Fix PKCS#7 decode routines so they correctly update the length
2470 after reading an EOC for the EXPLICIT tag.
2472 [This change does not apply to 0.9.7.]
2474 *) Fix bug in PKCS#12 key generation routines. This was triggered
2475 if a 3DES key was generated with a 0 initial byte. Include
2476 PKCS12_BROKEN_KEYGEN compilation option to retain the old
2477 (but broken) behaviour.
2480 *) Enhance bctest to search for a working bc along $PATH and print
2482 [Tim Rice <tim@multitalents.net> via Richard Levitte]
2484 *) Fix memory leaks in err.c: free err_data string if necessary;
2485 don't write to the wrong index in ERR_set_error_data.
2488 *) Implement ssl23_peek (analogous to ssl23_read), which previously
2492 *) Replace rdtsc with _emit statements for VC++ version 5.
2493 [Jeremy Cooper <jeremy@baymoo.org>]
2495 *) Make it possible to reuse SSLv2 sessions.
2498 *) In copy_email() check for >= 0 as a return value for
2499 X509_NAME_get_index_by_NID() since 0 is a valid index.
2500 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
2502 *) Avoid coredump with unsupported or invalid public keys by checking if
2503 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
2504 PKCS7_verify() fails with non detached data.
2507 *) Don't use getenv in library functions when run as setuid/setgid.
2508 New function OPENSSL_issetugid().
2511 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
2512 due to incorrect handling of multi-threading:
2514 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
2516 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
2518 3. Count how many times MemCheck_off() has been called so that
2519 nested use can be treated correctly. This also avoids
2520 inband-signalling in the previous code (which relied on the
2521 assumption that thread ID 0 is impossible).
2524 *) Add "-rand" option also to s_client and s_server.
2527 *) Fix CPU detection on Irix 6.x.
2528 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
2529 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
2531 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
2534 [This change does not apply to 0.9.7.]
2536 *) Use the cached encoding of an X509_NAME structure rather than
2537 copying it. This is apparently the reason for the libsafe "errors"
2538 but the code is actually correct.
2541 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
2542 Bleichenbacher's DSA attack.
2543 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
2544 to be set and top=0 forces the highest bit to be set; top=-1 is new
2545 and leaves the highest bit random.
2546 [Ulf Moeller, Bodo Moeller]
2548 *) In the NCONF_...-based implementations for CONF_... queries
2549 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
2550 a temporary CONF structure with the data component set to NULL
2551 (which gives segmentation faults in lh_retrieve).
2552 Instead, use NULL for the CONF pointer in CONF_get_string and
2553 CONF_get_number (which may use environment variables) and directly
2554 return NULL from CONF_get_section.
2557 *) Fix potential buffer overrun for EBCDIC.
2560 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
2561 keyUsage if basicConstraints absent for a CA.
2564 *) Make SMIME_write_PKCS7() write mail header values with a format that
2565 is more generally accepted (no spaces before the semicolon), since
2566 some programs can't parse those values properly otherwise. Also make
2567 sure BIO's that break lines after each write do not create invalid
2571 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
2572 macros previously used would not encode an empty SEQUENCE OF
2573 and break the signature.
2575 [This change does not apply to 0.9.7.]
2577 *) Zero the premaster secret after deriving the master secret in
2581 *) Add some EVP_add_digest_alias registrations (as found in
2582 OpenSSL_add_all_digests()) to SSL_library_init()
2583 aka OpenSSL_add_ssl_algorithms(). This provides improved
2584 compatibility with peers using X.509 certificates
2585 with unconventional AlgorithmIdentifier OIDs.
2588 *) Fix for Irix with NO_ASM.
2589 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
2591 *) ./config script fixes.
2592 [Ulf Moeller, Richard Levitte]
2594 *) Fix 'openssl passwd -1'.
2597 *) Change PKCS12_key_gen_asc() so it can cope with non null
2598 terminated strings whose length is passed in the passlen
2599 parameter, for example from PEM callbacks. This was done
2600 by adding an extra length parameter to asc2uni().
2601 [Steve Henson, reported by <oddissey@samsung.co.kr>]
2603 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
2604 call failed, free the DSA structure.
2607 *) Fix to uni2asc() to cope with zero length Unicode strings.
2608 These are present in some PKCS#12 files.
2611 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
2612 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
2613 when writing a 32767 byte record.
2614 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
2616 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
2617 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
2619 (RSA objects have a reference count access to which is protected
2620 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
2621 so they are meant to be shared between threads.)
2622 [Bodo Moeller, Geoff Thorpe; original patch submitted by
2623 "Reddie, Steven" <Steven.Reddie@ca.com>]
2625 *) Fix a deadlock in CRYPTO_mem_leaks().
2628 *) Use better test patterns in bntest.
2631 *) rand_win.c fix for Borland C.
2634 *) BN_rshift bugfix for n == 0.
2637 *) Add a 'bctest' script that checks for some known 'bc' bugs
2638 so that 'make test' does not abort just because 'bc' is broken.
2641 *) Store verify_result within SSL_SESSION also for client side to
2642 avoid potential security hole. (Re-used sessions on the client side
2643 always resulted in verify_result==X509_V_OK, not using the original
2644 result of the server certificate verification.)
2647 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
2648 SSL3_RT_APPLICATION_DATA, return 0.
2649 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
2653 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
2654 releases, have been re-implemented by renaming the previous
2655 implementations of ssl2_read and ssl3_read to ssl2_read_internal
2656 and ssl3_read_internal, respectively, and adding 'peek' parameters
2657 to them. The new ssl[23]_{read,peek} functions are calls to
2658 ssl[23]_read_internal with the 'peek' flag set appropriately.
2659 A 'peek' parameter has also been added to ssl3_read_bytes, which
2660 does the actual work for ssl3_read_internal.
2663 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
2664 the method-specific "init()" handler. Also clean up ex_data after
2665 calling the method-specific "finish()" handler. Previously, this was
2666 happening the other way round.
2669 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
2670 The previous value, 12, was not always sufficient for BN_mod_exp().
2673 *) Make sure that shared libraries get the internal name engine with
2674 the full version number and not just 0. This should mark the
2675 shared libraries as not backward compatible. Of course, this should
2676 be changed again when we can guarantee backward binary compatibility.
2679 *) Fix typo in get_cert_by_subject() in by_dir.c
2680 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
2682 *) Rework the system to generate shared libraries:
2684 - Make note of the expected extension for the shared libraries and
2685 if there is a need for symbolic links from for example libcrypto.so.0
2686 to libcrypto.so.0.9.7. There is extended info in Configure for
2689 - Make as few rebuilds of the shared libraries as possible.
2691 - Still avoid linking the OpenSSL programs with the shared libraries.
2693 - When installing, install the shared libraries separately from the
2697 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
2699 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
2700 and not in SSL_clear because the latter is also used by the
2701 accept/connect functions; previously, the settings made by
2702 SSL_set_read_ahead would be lost during the handshake.
2703 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
2705 *) Correct util/mkdef.pl to be selective about disabled algorithms.
2706 Previously, it would create entries for disableed algorithms no
2710 *) Added several new manual pages for SSL_* function.
2713 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
2715 *) In ssl23_get_client_hello, generate an error message when faced
2716 with an initial SSL 3.0/TLS record that is too small to contain the
2717 first two bytes of the ClientHello message, i.e. client_version.
2718 (Note that this is a pathologic case that probably has never happened
2719 in real life.) The previous approach was to use the version number
2720 from the record header as a substitute; but our protocol choice
2721 should not depend on that one because it is not authenticated
2722 by the Finished messages.
2725 *) More robust randomness gathering functions for Windows.
2726 [Jeffrey Altman <jaltman@columbia.edu>]
2728 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
2729 not set then we don't setup the error code for issuer check errors
2730 to avoid possibly overwriting other errors which the callback does
2731 handle. If an application does set the flag then we assume it knows
2732 what it is doing and can handle the new informational codes
2736 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
2737 a general "ANY" type, as such it should be able to decode anything
2738 including tagged types. However it didn't check the class so it would
2739 wrongly interpret tagged types in the same way as their universal
2740 counterpart and unknown types were just rejected. Changed so that the
2741 tagged and unknown types are handled in the same way as a SEQUENCE:
2742 that is the encoding is stored intact. There is also a new type
2743 "V_ASN1_OTHER" which is used when the class is not universal, in this
2744 case we have no idea what the actual type is so we just lump them all
2748 *) On VMS, stdout may very well lead to a file that is written to
2749 in a record-oriented fashion. That means that every write() will
2750 write a separate record, which will be read separately by the
2751 programs trying to read from it. This can be very confusing.
2753 The solution is to put a BIO filter in the way that will buffer
2754 text until a linefeed is reached, and then write everything a
2755 line at a time, so every record written will be an actual line,
2756 not chunks of lines and not (usually doesn't happen, but I've
2757 seen it once) several lines in one record. BIO_f_linebuffer() is
2760 Currently, it's a VMS-only method, because that's where it has
2761 been tested well enough.
2764 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
2765 it can return incorrect results.
2766 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
2767 but it was in 0.9.6-beta[12].)
2770 *) Disable the check for content being present when verifying detached
2771 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
2772 include zero length content when signing messages.
2775 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
2776 BIO_ctrl (for BIO pairs).
2779 *) Add DSO method for VMS.
2782 *) Bug fix: Montgomery multiplication could produce results with the
2786 *) Add RPM specification openssl.spec and modify it to build three
2787 packages. The default package contains applications, application
2788 documentation and run-time libraries. The devel package contains
2789 include files, static libraries and function documentation. The
2790 doc package contains the contents of the doc directory. The original
2791 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
2794 *) Add a large number of documentation files for many SSL routines.
2795 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2797 *) Add a configuration entry for Sony News 4.
2798 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
2800 *) Don't set the two most significant bits to one when generating a
2801 random number < q in the DSA library.
2804 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
2805 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
2806 the underlying transport is blocking) if a handshake took place.
2807 (The default behaviour is needed by applications such as s_client
2808 and s_server that use select() to determine when to use SSL_read;
2809 but for applications that know in advance when to expect data, it
2810 just makes things more complicated.)
2813 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
2817 *) Add a few more EBCDIC conditionals that make `req' and `x509'
2818 work better on such systems.
2819 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2821 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
2822 Update PKCS12_parse() so it copies the friendlyName and the
2823 keyid to the certificates aux info.
2826 *) Fix bug in PKCS7_verify() which caused an infinite loop
2827 if there was more than one signature.
2828 [Sven Uszpelkat <su@celocom.de>]
2830 *) Major change in util/mkdef.pl to include extra information
2831 about each symbol, as well as presentig variables as well
2832 as functions. This change means that there's n more need
2833 to rebuild the .num files when some algorithms are excluded.
2836 *) Allow the verify time to be set by an application,
2837 rather than always using the current time.
2840 *) Phase 2 verify code reorganisation. The certificate
2841 verify code now looks up an issuer certificate by a
2842 number of criteria: subject name, authority key id
2843 and key usage. It also verifies self signed certificates
2844 by the same criteria. The main comparison function is
2845 X509_check_issued() which performs these checks.
2847 Lot of changes were necessary in order to support this
2848 without completely rewriting the lookup code.
2850 Authority and subject key identifier are now cached.
2852 The LHASH 'certs' is X509_STORE has now been replaced
2853 by a STACK_OF(X509_OBJECT). This is mainly because an
2854 LHASH can't store or retrieve multiple objects with
2855 the same hash value.
2857 As a result various functions (which were all internal
2858 use only) have changed to handle the new X509_STORE
2859 structure. This will break anything that messed round
2860 with X509_STORE internally.
2862 The functions X509_STORE_add_cert() now checks for an
2863 exact match, rather than just subject name.
2865 The X509_STORE API doesn't directly support the retrieval
2866 of multiple certificates matching a given criteria, however
2867 this can be worked round by performing a lookup first
2868 (which will fill the cache with candidate certificates)
2869 and then examining the cache for matches. This is probably
2870 the best we can do without throwing out X509_LOOKUP
2871 entirely (maybe later...).
2873 The X509_VERIFY_CTX structure has been enhanced considerably.
2875 All certificate lookup operations now go via a get_issuer()
2876 callback. Although this currently uses an X509_STORE it
2877 can be replaced by custom lookups. This is a simple way
2878 to bypass the X509_STORE hackery necessary to make this
2879 work and makes it possible to use more efficient techniques
2880 in future. A very simple version which uses a simple
2881 STACK for its trusted certificate store is also provided
2882 using X509_STORE_CTX_trusted_stack().
2884 The verify_cb() and verify() callbacks now have equivalents
2885 in the X509_STORE_CTX structure.
2887 X509_STORE_CTX also has a 'flags' field which can be used
2888 to customise the verify behaviour.
2891 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
2892 excludes S/MIME capabilities.
2895 *) When a certificate request is read in keep a copy of the
2896 original encoding of the signed data and use it when outputing
2897 again. Signatures then use the original encoding rather than
2898 a decoded, encoded version which may cause problems if the
2899 request is improperly encoded.
2902 *) For consistency with other BIO_puts implementations, call
2903 buffer_write(b, ...) directly in buffer_puts instead of calling
2906 In BIO_puts, increment b->num_write as in BIO_write.
2907 [Peter.Sylvester@EdelWeb.fr]
2909 *) Fix BN_mul_word for the case where the word is 0. (We have to use
2910 BN_zero, we may not return a BIGNUM with an array consisting of
2914 *) Avoid calling abort() from within the library when problems are
2915 detected, except if preprocessor symbols have been defined
2916 (such as REF_CHECK, BN_DEBUG etc.).
2919 *) New openssl application 'rsautl'. This utility can be
2920 used for low level RSA operations. DER public key
2921 BIO/fp routines also added.
2924 *) New Configure entry and patches for compiling on QNX 4.
2925 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
2927 *) A demo state-machine implementation was sponsored by
2928 Nuron (http://www.nuron.com/) and is now available in
2929 demos/state_machine.
2932 *) New options added to the 'dgst' utility for signature
2933 generation and verification.
2936 *) Unrecognized PKCS#7 content types are now handled via a
2937 catch all ASN1_TYPE structure. This allows unsupported
2938 types to be stored as a "blob" and an application can
2939 encode and decode it manually.
2942 *) Fix various signed/unsigned issues to make a_strex.c
2944 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
2946 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
2947 length if passed a buffer. ASN1_INTEGER_to_BN failed
2948 if passed a NULL BN and its argument was negative.
2949 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
2951 *) Modification to PKCS#7 encoding routines to output definite
2952 length encoding. Since currently the whole structures are in
2953 memory there's not real point in using indefinite length
2954 constructed encoding. However if OpenSSL is compiled with
2955 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
2958 *) Added BIO_vprintf() and BIO_vsnprintf().
2961 *) Added more prefixes to parse for in the the strings written
2962 through a logging bio, to cover all the levels that are available
2963 through syslog. The prefixes are now:
2965 PANIC, EMERG, EMR => LOG_EMERG
2966 ALERT, ALR => LOG_ALERT
2967 CRIT, CRI => LOG_CRIT
2968 ERROR, ERR => LOG_ERR
2969 WARNING, WARN, WAR => LOG_WARNING
2970 NOTICE, NOTE, NOT => LOG_NOTICE
2971 INFO, INF => LOG_INFO
2972 DEBUG, DBG => LOG_DEBUG
2974 and as before, if none of those prefixes are present at the
2975 beginning of the string, LOG_ERR is chosen.
2977 On Win32, the LOG_* levels are mapped according to this:
2979 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
2980 LOG_WARNING => EVENTLOG_WARNING_TYPE
2981 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
2985 *) Made it possible to reconfigure with just the configuration
2986 argument "reconf" or "reconfigure". The command line arguments
2987 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
2988 and are retrieved from there when reconfiguring.
2992 [Assar Westerlund <assar@sics.se>, Richard Levitte]
2994 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
2997 *) The obj_dat.pl script was messing up the sorting of object
2998 names. The reason was that it compared the quoted version
2999 of strings as a result "OCSP" > "OCSP Signing" because
3000 " > SPACE. Changed script to store unquoted versions of
3001 names and add quotes on output. It was also omitting some
3002 names from the lookup table if they were given a default
3003 value (that is if SN is missing it is given the same
3004 value as LN and vice versa), these are now added on the
3005 grounds that if an object has a name we should be able to
3006 look it up. Finally added warning output when duplicate
3007 short or long names are found.
3010 *) Changes needed for Tandem NSK.
3011 [Scott Uroff <scott@xypro.com>]
3013 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
3014 RSA_padding_check_SSLv23(), special padding was never detected
3015 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
3016 version rollback attacks was not effective.
3018 In s23_clnt.c, don't use special rollback-attack detection padding
3019 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
3020 client; similarly, in s23_srvr.c, don't do the rollback check if
3021 SSL 2.0 is the only protocol enabled in the server.
3024 *) Make it possible to get hexdumps of unprintable data with 'openssl
3025 asn1parse'. By implication, the functions ASN1_parse_dump() and
3026 BIO_dump_indent() are added.
3029 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
3030 these print out strings and name structures based on various
3031 flags including RFC2253 support and proper handling of
3032 multibyte characters. Added options to the 'x509' utility
3033 to allow the various flags to be set.
3036 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
3037 Also change the functions X509_cmp_current_time() and
3038 X509_gmtime_adj() work with an ASN1_TIME structure,
3039 this will enable certificates using GeneralizedTime in validity
3040 dates to be checked.
3043 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
3044 negative public key encodings) on by default,
3045 NO_NEG_PUBKEY_BUG can be set to disable it.
3048 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
3049 content octets. An i2c_ASN1_OBJECT is unnecessary because
3050 the encoding can be trivially obtained from the structure.
3053 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
3054 not read locks (CRYPTO_r_[un]lock).
3057 *) A first attempt at creating official support for shared
3058 libraries through configuration. I've kept it so the
3059 default is static libraries only, and the OpenSSL programs
3060 are always statically linked for now, but there are
3061 preparations for dynamic linking in place.
3062 This has been tested on Linux and Tru64.
3065 *) Randomness polling function for Win9x, as described in:
3066 Peter Gutmann, Software Generation of Practically Strong
3070 *) Fix so PRNG is seeded in req if using an already existing
3074 *) New options to smime application. -inform and -outform
3075 allow alternative formats for the S/MIME message including
3076 PEM and DER. The -content option allows the content to be
3077 specified separately. This should allow things like Netscape
3078 form signing output easier to verify.
3081 *) Fix the ASN1 encoding of tags using the 'long form'.
3084 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
3085 STRING types. These convert content octets to and from the
3086 underlying type. The actual tag and length octets are
3087 already assumed to have been read in and checked. These
3088 are needed because all other string types have virtually
3089 identical handling apart from the tag. By having versions
3090 of the ASN1 functions that just operate on content octets
3091 IMPLICIT tagging can be handled properly. It also allows
3092 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
3093 and ASN1_INTEGER are identical apart from the tag.
3096 *) Change the handling of OID objects as follows:
3098 - New object identifiers are inserted in objects.txt, following
3099 the syntax given in objects.README.
3100 - objects.pl is used to process obj_mac.num and create a new
3102 - obj_dat.pl is used to create a new obj_dat.h, using the data in
3105 This is currently kind of a hack, and the perl code in objects.pl
3106 isn't very elegant, but it works as I intended. The simplest way
3107 to check that it worked correctly is to look in obj_dat.h and
3108 check the array nid_objs and make sure the objects haven't moved
3109 around (this is important!). Additions are OK, as well as
3110 consistent name changes.
3113 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
3116 *) Addition of the command line parameter '-rand file' to 'openssl req'.
3117 The given file adds to whatever has already been seeded into the
3118 random pool through the RANDFILE configuration file option or
3119 environment variable, or the default random state file.
3122 *) mkstack.pl now sorts each macro group into lexical order.
3123 Previously the output order depended on the order the files
3124 appeared in the directory, resulting in needless rewriting
3128 *) Patches to make OpenSSL compile under Win32 again. Mostly
3129 work arounds for the VC++ problem that it treats func() as
3130 func(void). Also stripped out the parts of mkdef.pl that
3131 added extra typesafe functions: these no longer exist.
3134 *) Reorganisation of the stack code. The macros are now all
3135 collected in safestack.h . Each macro is defined in terms of
3136 a "stack macro" of the form SKM_<name>(type, a, b). The
3137 DEBUG_SAFESTACK is now handled in terms of function casts,
3138 this has the advantage of retaining type safety without the
3139 use of additional functions. If DEBUG_SAFESTACK is not defined
3140 then the non typesafe macros are used instead. Also modified the
3141 mkstack.pl script to handle the new form. Needs testing to see
3142 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
3143 the default if no major problems. Similar behaviour for ASN1_SET_OF
3144 and PKCS12_STACK_OF.
3147 *) When some versions of IIS use the 'NET' form of private key the
3148 key derivation algorithm is different. Normally MD5(password) is
3149 used as a 128 bit RC4 key. In the modified case
3150 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
3151 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
3152 as the old Netscape_RSA functions except they have an additional
3153 'sgckey' parameter which uses the modified algorithm. Also added
3154 an -sgckey command line option to the rsa utility. Thanks to
3155 Adrian Peck <bertie@ncipher.com> for posting details of the modified
3156 algorithm to openssl-dev.
3159 *) The evp_local.h macros were using 'c.##kname' which resulted in
3160 invalid expansion on some systems (SCO 5.0.5 for example).
3161 Corrected to 'c.kname'.
3162 [Phillip Porch <root@theporch.com>]
3164 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
3165 a STACK of email addresses from a certificate or request, these look
3166 in the subject name and the subject alternative name extensions and
3167 omit any duplicate addresses.
3170 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
3171 This makes DSA verification about 2 % faster.
3174 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
3175 (meaning that now 2^5 values will be precomputed, which is only 4 KB
3176 plus overhead for 1024 bit moduli).
3177 This makes exponentiations about 0.5 % faster for 1024 bit
3178 exponents (as measured by "openssl speed rsa2048").
3181 *) Rename memory handling macros to avoid conflicts with other
3183 Malloc => OPENSSL_malloc
3184 Malloc_locked => OPENSSL_malloc_locked
3185 Realloc => OPENSSL_realloc
3186 Free => OPENSSL_free
3189 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
3190 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
3193 *) CygWin32 support.
3194 [John Jarvie <jjarvie@newsguy.com>]
3196 *) The type-safe stack code has been rejigged. It is now only compiled
3197 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
3198 by default all type-specific stack functions are "#define"d back to
3199 standard stack functions. This results in more streamlined output
3200 but retains the type-safety checking possibilities of the original
3204 *) The STACK code has been cleaned up, and certain type declarations
3205 that didn't make a lot of sense have been brought in line. This has
3206 also involved a cleanup of sorts in safestack.h to more correctly
3207 map type-safe stack functions onto their plain stack counterparts.
3208 This work has also resulted in a variety of "const"ifications of
3209 lots of the code, especially "_cmp" operations which should normally
3210 be prototyped with "const" parameters anyway.
3213 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
3214 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
3215 (The PRNG state consists of two parts, the large pool 'state' and 'md',
3216 where all of 'md' is used each time the PRNG is used, but 'state'
3217 is used only indexed by a cyclic counter. As entropy may not be
3218 well distributed from the beginning, 'md' is important as a
3219 chaining variable. However, the output function chains only half
3220 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
3221 all of 'md', and seeding with STATE_SIZE dummy bytes will result
3222 in all of 'state' being rewritten, with the new values depending
3223 on virtually all of 'md'. This overcomes the 80 bit limitation.)
3226 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
3227 the handshake is continued after ssl_verify_cert_chain();
3228 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
3229 can lead to 'unexplainable' connection aborts later.
3230 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
3232 *) Major EVP API cipher revision.
3233 Add hooks for extra EVP features. This allows various cipher
3234 parameters to be set in the EVP interface. Support added for variable
3235 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
3236 setting of RC2 and RC5 parameters.
3238 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
3241 Remove lots of duplicated code from the EVP library. For example *every*
3242 cipher init() function handles the 'iv' in the same way according to the
3243 cipher mode. They also all do nothing if the 'key' parameter is NULL and
3244 for CFB and OFB modes they zero ctx->num.
3246 New functionality allows removal of S/MIME code RC2 hack.
3248 Most of the routines have the same form and so can be declared in terms
3251 By shifting this to the top level EVP_CipherInit() it can be removed from
3252 all individual ciphers. If the cipher wants to handle IVs or keys
3253 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
3256 Change lots of functions like EVP_EncryptUpdate() to now return a
3257 value: although software versions of the algorithms cannot fail
3258 any installed hardware versions can.
3261 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
3262 this option is set, tolerate broken clients that send the negotiated
3263 protocol version number instead of the requested protocol version
3267 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
3268 i.e. non-zero for export ciphersuites, zero otherwise.
3269 Previous versions had this flag inverted, inconsistent with
3270 rsa_tmp_cb (..._TMP_RSA_CB).
3271 [Bodo Moeller; problem reported by Amit Chopra]
3273 *) Add missing DSA library text string. Work around for some IIS
3274 key files with invalid SEQUENCE encoding.
3277 *) Add a document (doc/standards.txt) that list all kinds of standards
3278 and so on that are implemented in OpenSSL.
3281 *) Enhance c_rehash script. Old version would mishandle certificates
3282 with the same subject name hash and wouldn't handle CRLs at all.
3283 Added -fingerprint option to crl utility, to support new c_rehash
3287 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
3290 *) Fix for SSL server purpose checking. Server checking was
3291 rejecting certificates which had extended key usage present
3292 but no ssl client purpose.
3293 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
3295 *) Make PKCS#12 code work with no password. The PKCS#12 spec
3296 is a little unclear about how a blank password is handled.
3297 Since the password in encoded as a BMPString with terminating
3298 double NULL a zero length password would end up as just the
3299 double NULL. However no password at all is different and is
3300 handled differently in the PKCS#12 key generation code. NS
3301 treats a blank password as zero length. MSIE treats it as no
3302 password on export: but it will try both on import. We now do
3303 the same: PKCS12_parse() tries zero length and no password if
3304 the password is set to "" or NULL (NULL is now a valid password:
3305 it wasn't before) as does the pkcs12 application.
3308 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
3309 perror when PEM_read_bio_X509_REQ fails, the error message must
3310 be obtained from the error queue.
3313 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
3314 it in ERR_remove_state if appropriate, and change ERR_get_state
3315 accordingly to avoid race conditions (this is necessary because
3316 thread_hash is no longer constant once set).
3319 *) Bugfix for linux-elf makefile.one.
3322 *) RSA_get_default_method() will now cause a default
3323 RSA_METHOD to be chosen if one doesn't exist already.
3324 Previously this was only set during a call to RSA_new()
3325 or RSA_new_method(NULL) meaning it was possible for
3326 RSA_get_default_method() to return NULL.
3329 *) Added native name translation to the existing DSO code
3330 that will convert (if the flag to do so is set) filenames
3331 that are sufficiently small and have no path information
3332 into a canonical native form. Eg. "blah" converted to
3333 "libblah.so" or "blah.dll" etc.
3336 *) New function ERR_error_string_n(e, buf, len) which is like
3337 ERR_error_string(e, buf), but writes at most 'len' bytes
3338 including the 0 terminator. For ERR_error_string_n, 'buf'
3340 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
3342 *) CONF library reworked to become more general. A new CONF
3343 configuration file reader "class" is implemented as well as a
3344 new functions (NCONF_*, for "New CONF") to handle it. The now
3345 old CONF_* functions are still there, but are reimplemented to
3346 work in terms of the new functions. Also, a set of functions
3347 to handle the internal storage of the configuration data is
3348 provided to make it easier to write new configuration file
3349 reader "classes" (I can definitely see something reading a
3350 configuration file in XML format, for example), called _CONF_*,
3351 or "the configuration storage API"...
3353 The new configuration file reading functions are:
3355 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
3356 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
3358 NCONF_default, NCONF_WIN32
3360 NCONF_dump_fp, NCONF_dump_bio
3362 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
3363 NCONF_new creates a new CONF object. This works in the same way
3364 as other interfaces in OpenSSL, like the BIO interface.
3365 NCONF_dump_* dump the internal storage of the configuration file,
3366 which is useful for debugging. All other functions take the same
3367 arguments as the old CONF_* functions wth the exception of the
3368 first that must be a `CONF *' instead of a `LHASH *'.
3370 To make it easer to use the new classes with the old CONF_* functions,
3371 the function CONF_set_default_method is provided.
3374 *) Add '-tls1' option to 'openssl ciphers', which was already
3375 mentioned in the documentation but had not been implemented.
3376 (This option is not yet really useful because even the additional
3377 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
3380 *) Initial DSO code added into libcrypto for letting OpenSSL (and
3381 OpenSSL-based applications) load shared libraries and bind to
3382 them in a portable way.
3383 [Geoff Thorpe, with contributions from Richard Levitte]
3385 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
3387 *) Make sure _lrotl and _lrotr are only used with MSVC.
3389 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
3390 (the default implementation of RAND_status).
3392 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
3393 to '-clrext' (= clear extensions), as intended and documented.
3394 [Bodo Moeller; inconsistency pointed out by Michael Attili
3397 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
3398 was larger than the MD block size.
3399 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
3401 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
3402 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
3403 using the passed key: if the passed key was a private key the result
3404 of X509_print(), for example, would be to print out all the private key
3408 *) des_quad_cksum() byte order bug fix.
3409 [Ulf Möller, using the problem description in krb4-0.9.7, where
3410 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
3412 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
3414 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
3416 *) For easily testing in shell scripts whether some command
3417 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
3418 returns with exit code 0 iff no command of the given name is available.
3419 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
3420 the output goes to stdout and nothing is printed to stderr.
3421 Additional arguments are always ignored.
3423 Since for each cipher there is a command of the same name,
3424 the 'no-cipher' compilation switches can be tested this way.
3426 ('openssl no-XXX' is not able to detect pseudo-commands such
3427 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
3430 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
3433 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
3434 is set; it will be thrown away anyway because each handshake creates
3436 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
3437 to parameters -- in previous versions (since OpenSSL 0.9.3) the
3438 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
3439 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
3442 *) New s_client option -ign_eof: EOF at stdin is ignored, and
3443 'Q' and 'R' lose their special meanings (quit/renegotiate).
3444 This is part of what -quiet does; unlike -quiet, -ign_eof
3445 does not suppress any output.
3448 *) Add compatibility options to the purpose and trust code. The
3449 purpose X509_PURPOSE_ANY is "any purpose" which automatically
3450 accepts a certificate or CA, this was the previous behaviour,
3451 with all the associated security issues.
3453 X509_TRUST_COMPAT is the old trust behaviour: only and
3454 automatically trust self signed roots in certificate store. A
3455 new trust setting X509_TRUST_DEFAULT is used to specify that
3456 a purpose has no associated trust setting and it should instead
3457 use the value in the default purpose.
3460 *) Fix the PKCS#8 DSA private key code so it decodes keys again
3461 and fix a memory leak.
3464 *) In util/mkerr.pl (which implements 'make errors'), preserve
3465 reason strings from the previous version of the .c file, as
3466 the default to have only downcase letters (and digits) in
3467 automatically generated reasons codes is not always appropriate.
3470 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
3471 using strerror. Previously, ERR_reason_error_string() returned
3472 library names as reason strings for SYSerr; but SYSerr is a special
3473 case where small numbers are errno values, not library numbers.
3476 *) Add '-dsaparam' option to 'openssl dhparam' application. This
3477 converts DSA parameters into DH parameters. (When creating parameters,
3478 DSA_generate_parameters is used.)
3481 *) Include 'length' (recommended exponent length) in C code generated
3482 by 'openssl dhparam -C'.
3485 *) The second argument to set_label in perlasm was already being used
3486 so couldn't be used as a "file scope" flag. Moved to third argument
3490 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
3491 instead of RAND_bytes for encryption IVs and salts.
3494 *) Include RAND_status() into RAND_METHOD instead of implementing
3495 it only for md_rand.c Otherwise replacing the PRNG by calling
3496 RAND_set_rand_method would be impossible.
3499 *) Don't let DSA_generate_key() enter an infinite loop if the random
3500 number generation fails.
3503 *) New 'rand' application for creating pseudo-random output.
3506 *) Added configuration support for Linux/IA64
3507 [Rolf Haberrecker <rolf@suse.de>]
3509 *) Assembler module support for Mingw32.
3512 *) Shared library support for HPUX (in shlib/).
3513 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
3515 *) Shared library support for Solaris gcc.
3516 [Lutz Behnke <behnke@trustcenter.de>]
3518 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
3520 *) PKCS7_encrypt() was adding text MIME headers twice because they
3521 were added manually and by SMIME_crlf_copy().
3524 *) In bntest.c don't call BN_rand with zero bits argument.
3525 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
3527 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
3528 case was implemented. This caused BN_div_recp() to fail occasionally.
3531 *) Add an optional second argument to the set_label() in the perl
3532 assembly language builder. If this argument exists and is set
3533 to 1 it signals that the assembler should use a symbol whose
3534 scope is the entire file, not just the current function. This
3535 is needed with MASM which uses the format label:: for this scope.
3536 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
3538 *) Change the ASN1 types so they are typedefs by default. Before
3539 almost all types were #define'd to ASN1_STRING which was causing
3540 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
3544 *) Change names of new functions to the new get1/get0 naming
3545 convention: After 'get1', the caller owns a reference count
3546 and has to call ..._free; 'get0' returns a pointer to some
3547 data structure without incrementing reference counters.
3548 (Some of the existing 'get' functions increment a reference
3549 counter, some don't.)
3550 Similarly, 'set1' and 'add1' functions increase reference
3551 counters or duplicate objects.
3554 *) Allow for the possibility of temp RSA key generation failure:
3555 the code used to assume it always worked and crashed on failure.
3558 *) Fix potential buffer overrun problem in BIO_printf().
3559 [Ulf Möller, using public domain code by Patrick Powell; problem
3560 pointed out by David Sacerdote <das33@cornell.edu>]
3562 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
3563 RAND_egd() and RAND_status(). In the command line application,
3564 the EGD socket can be specified like a seed file using RANDFILE
3568 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
3569 Some CAs (e.g. Verisign) distribute certificates in this form.
3572 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
3573 list to exclude them. This means that no special compilation option
3574 is needed to use anonymous DH: it just needs to be included in the
3578 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
3579 EVP_MD_type. The old functionality is available in a new macro called
3580 EVP_MD_md(). Change code that uses it and update docs.
3583 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
3584 where the 'void *' argument is replaced by a function pointer argument.
3585 Previously 'void *' was abused to point to functions, which works on
3586 many platforms, but is not correct. As these functions are usually
3587 called by macros defined in OpenSSL header files, most source code
3588 should work without changes.
3591 *) <openssl/opensslconf.h> (which is created by Configure) now contains
3592 sections with information on -D... compiler switches used for
3593 compiling the library so that applications can see them. To enable
3594 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
3595 must be defined. E.g.,
3596 #define OPENSSL_ALGORITHM_DEFINES
3597 #include <openssl/opensslconf.h>
3598 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
3599 [Richard Levitte, Ulf and Bodo Möller]
3601 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
3605 *) Change the 'other' type in certificate aux info to a STACK_OF
3606 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
3607 the required ASN1 format: arbitrary types determined by an OID.
3610 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
3611 argument to 'req'. This is not because the function is newer or
3612 better than others it just uses the work 'NEW' in the certificate
3613 request header lines. Some software needs this.
3616 *) Reorganise password command line arguments: now passwords can be
3617 obtained from various sources. Delete the PEM_cb function and make
3618 it the default behaviour: i.e. if the callback is NULL and the
3619 usrdata argument is not NULL interpret it as a null terminated pass
3620 phrase. If usrdata and the callback are NULL then the pass phrase
3621 is prompted for as usual.
3624 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
3625 the support is automatically enabled. The resulting binaries will
3626 autodetect the card and use it if present.
3627 [Ben Laurie and Compaq Inc.]
3629 *) Work around for Netscape hang bug. This sends certificate request
3630 and server done in one record. Since this is perfectly legal in the
3631 SSL/TLS protocol it isn't a "bug" option and is on by default. See
3632 the bugs/SSLv3 entry for more info.
3635 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
3638 *) Add -rand argument to smime and pkcs12 applications and read/write
3642 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
3645 *) Add command line password options to the remaining applications.
3648 *) Bug fix for BN_div_recp() for numerators with an even number of
3652 *) More tests in bntest.c, and changed test_bn output.
3655 *) ./config recognizes MacOS X now.
3658 *) Bug fix for BN_div() when the first words of num and divsor are
3659 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
3662 *) Add support for various broken PKCS#8 formats, and command line
3663 options to produce them.
3666 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
3667 get temporary BIGNUMs from a BN_CTX.
3670 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
3674 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
3675 include a #define from the old name to the new. The original intent
3676 was that statically linked binaries could for example just call
3677 SSLeay_add_all_ciphers() to just add ciphers to the table and not
3678 link with digests. This never worked becayse SSLeay_add_all_digests()
3679 and SSLeay_add_all_ciphers() were in the same source file so calling
3680 one would link with the other. They are now in separate source files.
3683 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
3686 *) Use a less unusual form of the Miller-Rabin primality test (it used
3687 a binary algorithm for exponentiation integrated into the Miller-Rabin
3688 loop, our standard modexp algorithms are faster).
3691 *) Support for the EBCDIC character set completed.
3692 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
3694 *) Source code cleanups: use const where appropriate, eliminate casts,
3695 use void * instead of char * in lhash.
3698 *) Bugfix: ssl3_send_server_key_exchange was not restartable
3699 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
3700 this the server could overwrite ephemeral keys that the client
3704 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
3705 using 50 iterations of the Rabin-Miller test.
3707 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
3708 iterations of the Rabin-Miller test as required by the appendix
3709 to FIPS PUB 186[-1]) instead of DSA_is_prime.
3710 As BN_is_prime_fasttest includes trial division, DSA parameter
3711 generation becomes much faster.
3713 This implies a change for the callback functions in DSA_is_prime
3714 and DSA_generate_parameters: The callback function is called once
3715 for each positive witness in the Rabin-Miller test, not just
3716 occasionally in the inner loop; and the parameters to the
3717 callback function now provide an iteration count for the outer
3718 loop rather than for the current invocation of the inner loop.
3719 DSA_generate_parameters additionally can call the callback
3720 function with an 'iteration count' of -1, meaning that a
3721 candidate has passed the trial division test (when q is generated
3722 from an application-provided seed, trial division is skipped).
3725 *) New function BN_is_prime_fasttest that optionally does trial
3726 division before starting the Rabin-Miller test and has
3727 an additional BN_CTX * argument (whereas BN_is_prime always
3728 has to allocate at least one BN_CTX).
3729 'callback(1, -1, cb_arg)' is called when a number has passed the
3730 trial division stage.
3733 *) Fix for bug in CRL encoding. The validity dates weren't being handled
3737 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
3740 *) New function BN_pseudo_rand().
3743 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
3744 bignum version of BN_from_montgomery() with the working code from
3745 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
3749 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
3750 made it impossible to use the same SSL_SESSION data structure in
3751 SSL2 clients in multiple threads.
3754 *) The return value of RAND_load_file() no longer counts bytes obtained
3755 by stat(). RAND_load_file(..., -1) is new and uses the complete file
3756 to seed the PRNG (previously an explicit byte count was required).
3757 [Ulf Möller, Bodo Möller]
3759 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
3760 used (char *) instead of (void *) and had casts all over the place.
3763 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
3766 *) Retain source code compatibility for BN_prime_checks macro:
3767 BN_is_prime(..., BN_prime_checks, ...) now uses
3768 BN_prime_checks_for_size to determine the appropriate number of
3769 Rabin-Miller iterations.
3772 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
3773 DH_CHECK_P_NOT_SAFE_PRIME.
3774 (Check if this is true? OpenPGP calls them "strong".)
3777 *) Merge the functionality of "dh" and "gendh" programs into a new program
3778 "dhparam". The old programs are retained for now but will handle DH keys
3779 (instead of parameters) in future.
3782 *) Make the ciphers, s_server and s_client programs check the return values
3783 when a new cipher list is set.
3786 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
3787 ciphers. Before when the 56bit ciphers were enabled the sorting was
3790 The syntax for the cipher sorting has been extended to support sorting by
3791 cipher-strength (using the strength_bits hard coded in the tables).
3792 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
3794 Fix a bug in the cipher-command parser: when supplying a cipher command
3795 string with an "undefined" symbol (neither command nor alphanumeric
3796 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
3797 an error is flagged.
3799 Due to the strength-sorting extension, the code of the
3800 ssl_create_cipher_list() function was completely rearranged. I hope that
3801 the readability was also increased :-)
3802 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
3804 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
3805 for the first serial number and places 2 in the serial number file. This
3806 avoids problems when the root CA is created with serial number zero and
3807 the first user certificate has the same issuer name and serial number
3811 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
3812 the new code. Add documentation for this stuff.
3815 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
3816 X509_*() to X509at_*() on the grounds that they don't handle X509
3817 structures and behave in an analagous way to the X509v3 functions:
3818 they shouldn't be called directly but wrapper functions should be used
3821 So we also now have some wrapper functions that call the X509at functions
3822 when passed certificate requests. (TO DO: similar things can be done with
3823 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
3824 things. Some of these need some d2i or i2d and print functionality
3825 because they handle more complex structures.)
3828 *) Add missing #ifndefs that caused missing symbols when building libssl
3829 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
3830 NO_RSA in ssl/s2*.c.
3831 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
3833 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
3834 has a return value which indicates the quality of the random data
3835 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
3836 error queue. New function RAND_pseudo_bytes() generates output that is
3837 guaranteed to be unique but not unpredictable. RAND_add is like
3838 RAND_seed, but takes an extra argument for an entropy estimate
3839 (RAND_seed always assumes full entropy).
3842 *) Do more iterations of Rabin-Miller probable prime test (specifically,
3843 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
3844 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
3845 in crypto/bn/bn_prime.c for the complete table). This guarantees a
3846 false-positive rate of at most 2^-80 for random input.
3849 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
3852 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
3853 in the 0.9.5 release), this returns the chain
3854 from an X509_CTX structure with a dup of the stack and all
3855 the X509 reference counts upped: so the stack will exist
3856 after X509_CTX_cleanup() has been called. Modify pkcs12.c
3859 Also make SSL_SESSION_print() print out the verify return
3863 *) Add manpage for the pkcs12 command. Also change the default
3864 behaviour so MAC iteration counts are used unless the new
3865 -nomaciter option is used. This improves file security and
3866 only older versions of MSIE (4.0 for example) need it.
3869 *) Honor the no-xxx Configure options when creating .DEF files.
3872 *) Add PKCS#10 attributes to field table: challengePassword,
3873 unstructuredName and unstructuredAddress. These are taken from
3874 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
3875 international characters are used.
3877 More changes to X509_ATTRIBUTE code: allow the setting of types
3878 based on strings. Remove the 'loc' parameter when adding
3879 attributes because these will be a SET OF encoding which is sorted
3883 *) Initial changes to the 'req' utility to allow request generation
3884 automation. This will allow an application to just generate a template
3885 file containing all the field values and have req construct the
3888 Initial support for X509_ATTRIBUTE handling. Stacks of these are
3889 used all over the place including certificate requests and PKCS#7
3890 structures. They are currently handled manually where necessary with
3891 some primitive wrappers for PKCS#7. The new functions behave in a
3892 manner analogous to the X509 extension functions: they allow
3893 attributes to be looked up by NID and added.
3895 Later something similar to the X509V3 code would be desirable to
3896 automatically handle the encoding, decoding and printing of the
3897 more complex types. The string types like challengePassword can
3898 be handled by the string table functions.
3900 Also modified the multi byte string table handling. Now there is
3901 a 'global mask' which masks out certain types. The table itself
3902 can use the flag STABLE_NO_MASK to ignore the mask setting: this
3903 is useful when for example there is only one permissible type
3904 (as in countryName) and using the mask might result in no valid
3908 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
3909 SSL_get_peer_finished to allow applications to obtain the latest
3910 Finished messages sent to the peer or expected from the peer,
3911 respectively. (SSL_get_peer_finished is usually the Finished message
3912 actually received from the peer, otherwise the protocol will be aborted.)
3914 As the Finished message are message digests of the complete handshake
3915 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
3916 be used for external authentication procedures when the authentication
3917 provided by SSL/TLS is not desired or is not enough.
3920 *) Enhanced support for Alpha Linux is added. Now ./config checks if
3921 the host supports BWX extension and if Compaq C is present on the
3922 $PATH. Just exploiting of the BWX extension results in 20-30%
3923 performance kick for some algorithms, e.g. DES and RC4 to mention
3924 a couple. Compaq C in turn generates ~20% faster code for MD5 and
3928 *) Add support for MS "fast SGC". This is arguably a violation of the
3929 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
3930 weak crypto and after checking the certificate is SGC a second one
3931 with strong crypto. MS SGC stops the first handshake after receiving
3932 the server certificate message and sends a second client hello. Since
3933 a server will typically do all the time consuming operations before
3934 expecting any further messages from the client (server key exchange
3935 is the most expensive) there is little difference between the two.
3937 To get OpenSSL to support MS SGC we have to permit a second client
3938 hello message after we have sent server done. In addition we have to
3939 reset the MAC if we do get this second client hello.
3942 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
3943 if a DER encoded private key is RSA or DSA traditional format. Changed
3944 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
3945 format DER encoded private key. Newer code should use PKCS#8 format which
3946 has the key type encoded in the ASN1 structure. Added DER private key
3947 support to pkcs8 application.
3950 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
3951 ciphersuites has been selected (as required by the SSL 3/TLS 1
3952 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
3953 is set, we interpret this as a request to violate the specification
3954 (the worst that can happen is a handshake failure, and 'correct'
3955 behaviour would result in a handshake failure anyway).
3958 *) In SSL_CTX_add_session, take into account that there might be multiple
3959 SSL_SESSION structures with the same session ID (e.g. when two threads
3960 concurrently obtain them from an external cache).
3961 The internal cache can handle only one SSL_SESSION with a given ID,
3962 so if there's a conflict, we now throw out the old one to achieve
3966 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
3967 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
3968 some routines that use cipher OIDs: some ciphers do not have OIDs
3969 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
3973 *) Simplify the trust setting structure and code. Now we just have
3974 two sequences of OIDs for trusted and rejected settings. These will
3975 typically have values the same as the extended key usage extension
3976 and any application specific purposes.
3978 The trust checking code now has a default behaviour: it will just
3979 check for an object with the same NID as the passed id. Functions can
3980 be provided to override either the default behaviour or the behaviour
3981 for a given id. SSL client, server and email already have functions
3982 in place for compatibility: they check the NID and also return "trusted"
3983 if the certificate is self signed.
3986 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
3987 traditional format into an EVP_PKEY structure.
3990 *) Add a password callback function PEM_cb() which either prompts for
3991 a password if usr_data is NULL or otherwise assumes it is a null
3992 terminated password. Allow passwords to be passed on command line
3993 environment or config files in a few more utilities.
3996 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
3997 keys. Add some short names for PKCS#8 PBE algorithms and allow them
3998 to be specified on the command line for the pkcs8 and pkcs12 utilities.
3999 Update documentation.
4002 *) Support for ASN1 "NULL" type. This could be handled before by using
4003 ASN1_TYPE but there wasn't any function that would try to read a NULL
4004 and produce an error if it couldn't. For compatibility we also have
4005 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
4006 don't allocate anything because they don't need to.
4009 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
4011 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
4013 *) Rebuild of the memory allocation routines used by OpenSSL code and
4014 possibly others as well. The purpose is to make an interface that
4015 provide hooks so anyone can build a separate set of allocation and
4016 deallocation routines to be used by OpenSSL, for example memory
4017 pool implementations, or something else, which was previously hard
4018 since Malloc(), Realloc() and Free() were defined as macros having
4019 the values malloc, realloc and free, respectively (except for Win32
4020 compilations). The same is provided for memory debugging code.
4021 OpenSSL already comes with functionality to find memory leaks, but
4022 this gives people a chance to debug other memory problems.
4024 With these changes, a new set of functions and macros have appeared:
4026 CRYPTO_set_mem_debug_functions() [F]
4027 CRYPTO_get_mem_debug_functions() [F]
4028 CRYPTO_dbg_set_options() [F]
4029 CRYPTO_dbg_get_options() [F]
4030 CRYPTO_malloc_debug_init() [M]
4032 The memory debug functions are NULL by default, unless the library
4033 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
4034 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
4035 gives the standard debugging functions that come with OpenSSL) or
4036 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
4037 provided by the library user) must be used. When the standard
4038 debugging functions are used, CRYPTO_dbg_set_options can be used to
4039 request additional information:
4040 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
4041 the CRYPTO_MDEBUG_xxx macro when compiling the library.
4043 Also, things like CRYPTO_set_mem_functions will always give the
4044 expected result (the new set of functions is used for allocation
4045 and deallocation) at all times, regardless of platform and compiler
4048 To finish it up, some functions that were never use in any other
4049 way than through macros have a new API and new semantic:
4052 CRYPTO_dbg_realloc()
4055 All macros of value have retained their old syntax.
4056 [Richard Levitte and Bodo Moeller]
4058 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
4059 ordering of SMIMECapabilities wasn't in "strength order" and there
4060 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
4064 *) Some ASN1 types with illegal zero length encoding (INTEGER,
4065 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
4066 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
4068 *) Merge in my S/MIME library for OpenSSL. This provides a simple
4069 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
4070 functionality to handle multipart/signed properly) and a utility
4071 called 'smime' to call all this stuff. This is based on code I
4072 originally wrote for Celo who have kindly allowed it to be
4073 included in OpenSSL.
4076 *) Add variants des_set_key_checked and des_set_key_unchecked of
4077 des_set_key (aka des_key_sched). Global variable des_check_key
4078 decides which of these is called by des_set_key; this way
4079 des_check_key behaves as it always did, but applications and
4080 the library itself, which was buggy for des_check_key == 1,
4081 have a cleaner way to pick the version they need.
4084 *) New function PKCS12_newpass() which changes the password of a
4088 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
4089 dynamic mix. In both cases the ids can be used as an index into the
4090 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
4091 functions so they accept a list of the field values and the
4092 application doesn't need to directly manipulate the X509_TRUST
4096 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
4100 *) Modify the way the V3 extension code looks up extensions. This now
4101 works in a similar way to the object code: we have some "standard"
4102 extensions in a static table which is searched with OBJ_bsearch()
4103 and the application can add dynamic ones if needed. The file
4104 crypto/x509v3/ext_dat.h now has the info: this file needs to be
4105 updated whenever a new extension is added to the core code and kept
4106 in ext_nid order. There is a simple program 'tabtest.c' which checks
4107 this. New extensions are not added too often so this file can readily
4108 be maintained manually.
4110 There are two big advantages in doing things this way. The extensions
4111 can be looked up immediately and no longer need to be "added" using
4112 X509V3_add_standard_extensions(): this function now does nothing.
4113 [Side note: I get *lots* of email saying the extension code doesn't
4114 work because people forget to call this function]
4115 Also no dynamic allocation is done unless new extensions are added:
4116 so if we don't add custom extensions there is no need to call
4117 X509V3_EXT_cleanup().
4120 *) Modify enc utility's salting as follows: make salting the default. Add a
4121 magic header, so unsalted files fail gracefully instead of just decrypting
4122 to garbage. This is because not salting is a big security hole, so people
4123 should be discouraged from doing it.
4126 *) Fixes and enhancements to the 'x509' utility. It allowed a message
4127 digest to be passed on the command line but it only used this
4128 parameter when signing a certificate. Modified so all relevant
4129 operations are affected by the digest parameter including the
4130 -fingerprint and -x509toreq options. Also -x509toreq choked if a
4131 DSA key was used because it didn't fix the digest.
4134 *) Initial certificate chain verify code. Currently tests the untrusted
4135 certificates for consistency with the verify purpose (which is set
4136 when the X509_STORE_CTX structure is set up) and checks the pathlength.
4138 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
4139 this is because it will reject chains with invalid extensions whereas
4140 every previous version of OpenSSL and SSLeay made no checks at all.
4142 Trust code: checks the root CA for the relevant trust settings. Trust
4143 settings have an initial value consistent with the verify purpose: e.g.
4144 if the verify purpose is for SSL client use it expects the CA to be
4145 trusted for SSL client use. However the default value can be changed to
4146 permit custom trust settings: one example of this would be to only trust
4147 certificates from a specific "secure" set of CAs.
4149 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
4150 which should be used for version portability: especially since the
4151 verify structure is likely to change more often now.
4153 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
4154 to set them. If not set then assume SSL clients will verify SSL servers
4157 Two new options to the verify program: -untrusted allows a set of
4158 untrusted certificates to be passed in and -purpose which sets the
4159 intended purpose of the certificate. If a purpose is set then the
4160 new chain verify code is used to check extension consistency.
4163 *) Support for the authority information access extension.
4166 *) Modify RSA and DSA PEM read routines to transparently handle
4167 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
4168 public keys in a format compatible with certificate
4169 SubjectPublicKeyInfo structures. Unfortunately there were already
4170 functions called *_PublicKey_* which used various odd formats so
4171 these are retained for compatibility: however the DSA variants were
4172 never in a public release so they have been deleted. Changed dsa/rsa
4173 utilities to handle the new format: note no releases ever handled public
4174 keys so we should be OK.
4176 The primary motivation for this change is to avoid the same fiasco
4177 that dogs private keys: there are several incompatible private key
4178 formats some of which are standard and some OpenSSL specific and
4179 require various evil hacks to allow partial transparent handling and
4180 even then it doesn't work with DER formats. Given the option anything
4181 other than PKCS#8 should be dumped: but the other formats have to
4182 stay in the name of compatibility.
4184 With public keys and the benefit of hindsight one standard format
4185 is used which works with EVP_PKEY, RSA or DSA structures: though
4186 it clearly returns an error if you try to read the wrong kind of key.
4188 Added a -pubkey option to the 'x509' utility to output the public key.
4189 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
4190 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
4191 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
4192 that do the same as the EVP_PKEY_assign_*() except they up the
4193 reference count of the added key (they don't "swallow" the
4197 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
4198 CRLs would fail if the file contained no certificates or no CRLs:
4199 added a new function to read in both types and return the number
4200 read: this means that if none are read it will be an error. The
4201 DER versions of the certificate and CRL reader would always fail
4202 because it isn't possible to mix certificates and CRLs in DER format
4203 without choking one or the other routine. Changed this to just read
4204 a certificate: this is the best we can do. Also modified the code
4205 in apps/verify.c to take notice of return codes: it was previously
4206 attempting to read in certificates from NULL pointers and ignoring
4207 any errors: this is one reason why the cert and CRL reader seemed
4208 to work. It doesn't check return codes from the default certificate
4209 routines: these may well fail if the certificates aren't installed.
4212 *) Code to support otherName option in GeneralName.
4215 *) First update to verify code. Change the verify utility
4216 so it warns if it is passed a self signed certificate:
4217 for consistency with the normal behaviour. X509_verify
4218 has been modified to it will now verify a self signed
4219 certificate if *exactly* the same certificate appears
4220 in the store: it was previously impossible to trust a
4221 single self signed certificate. This means that:
4222 openssl verify ss.pem
4223 now gives a warning about a self signed certificate but
4224 openssl verify -CAfile ss.pem ss.pem
4228 *) For servers, store verify_result in SSL_SESSION data structure
4229 (and add it to external session representation).
4230 This is needed when client certificate verifications fails,
4231 but an application-provided verification callback (set by
4232 SSL_CTX_set_cert_verify_callback) allows accepting the session
4233 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
4234 but returns 1): When the session is reused, we have to set
4235 ssl->verify_result to the appropriate error code to avoid
4237 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
4239 *) Fix a bug in the new PKCS#7 code: it didn't consider the
4240 case in PKCS7_dataInit() where the signed PKCS7 structure
4241 didn't contain any existing data because it was being created.
4242 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
4244 *) Add a salt to the key derivation routines in enc.c. This
4245 forms the first 8 bytes of the encrypted file. Also add a
4246 -S option to allow a salt to be input on the command line.
4249 *) New function X509_cmp(). Oddly enough there wasn't a function
4250 to compare two certificates. We do this by working out the SHA1
4251 hash and comparing that. X509_cmp() will be needed by the trust
4255 *) SSL_get1_session() is like SSL_get_session(), but increments
4256 the reference count in the SSL_SESSION returned.
4257 [Geoff Thorpe <geoff@eu.c2.net>]
4259 *) Fix for 'req': it was adding a null to request attributes.
4260 Also change the X509_LOOKUP and X509_INFO code to handle
4261 certificate auxiliary information.
4264 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
4268 *) Add the possibility to add extra information to the memory leak
4269 detecting output, to form tracebacks, showing from where each
4270 allocation was originated: CRYPTO_push_info("constant string") adds
4271 the string plus current file name and line number to a per-thread
4272 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
4273 is like calling CYRPTO_pop_info() until the stack is empty.
4274 Also updated memory leak detection code to be multi-thread-safe.
4277 *) Add options -text and -noout to pkcs7 utility and delete the
4278 encryption options which never did anything. Update docs.
4281 *) Add options to some of the utilities to allow the pass phrase
4282 to be included on either the command line (not recommended on
4283 OSes like Unix) or read from the environment. Update the
4284 manpages and fix a few bugs.
4287 *) Add a few manpages for some of the openssl commands.
4290 *) Fix the -revoke option in ca. It was freeing up memory twice,
4291 leaking and not finding already revoked certificates.
4294 *) Extensive changes to support certificate auxiliary information.
4295 This involves the use of X509_CERT_AUX structure and X509_AUX
4296 functions. An X509_AUX function such as PEM_read_X509_AUX()
4297 can still read in a certificate file in the usual way but it
4298 will also read in any additional "auxiliary information". By
4299 doing things this way a fair degree of compatibility can be
4300 retained: existing certificates can have this information added
4301 using the new 'x509' options.
4303 Current auxiliary information includes an "alias" and some trust
4304 settings. The trust settings will ultimately be used in enhanced
4305 certificate chain verification routines: currently a certificate
4306 can only be trusted if it is self signed and then it is trusted
4310 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
4311 The problem was that one of the replacement routines had not been working
4312 since SSLeay releases. For now the offending routine has been replaced
4313 with non-optimised assembler. Even so, this now gives around 95%
4314 performance improvement for 1024 bit RSA signs.
4317 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
4318 handling. Most clients have the effective key size in bits equal to
4319 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
4320 A few however don't do this and instead use the size of the decrypted key
4321 to determine the RC2 key length and the AlgorithmIdentifier to determine
4322 the effective key length. In this case the effective key length can still
4323 be 40 bits but the key length can be 168 bits for example. This is fixed
4324 by manually forcing an RC2 key into the EVP_PKEY structure because the
4325 EVP code can't currently handle unusual RC2 key sizes: it always assumes
4326 the key length and effective key length are equal.
4329 *) Add a bunch of functions that should simplify the creation of
4330 X509_NAME structures. Now you should be able to do:
4331 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
4332 and have it automatically work out the correct field type and fill in
4333 the structures. The more adventurous can try:
4334 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
4335 and it will (hopefully) work out the correct multibyte encoding.
4338 *) Change the 'req' utility to use the new field handling and multibyte
4339 copy routines. Before the DN field creation was handled in an ad hoc
4340 way in req, ca, and x509 which was rather broken and didn't support
4341 BMPStrings or UTF8Strings. Since some software doesn't implement
4342 BMPStrings or UTF8Strings yet, they can be enabled using the config file
4343 using the dirstring_type option. See the new comment in the default
4344 openssl.cnf for more info.
4347 *) Make crypto/rand/md_rand.c more robust:
4348 - Assure unique random numbers after fork().
4349 - Make sure that concurrent threads access the global counter and
4350 md serializably so that we never lose entropy in them
4351 or use exactly the same state in multiple threads.
4352 Access to the large state is not always serializable because
4353 the additional locking could be a performance killer, and
4354 md should be large enough anyway.
4357 *) New file apps/app_rand.c with commonly needed functionality
4358 for handling the random seed file.
4360 Use the random seed file in some applications that previously did not:
4362 dsaparam -genkey (which also ignored its '-rand' option),
4365 x509 (when signing).
4366 Except on systems with /dev/urandom, it is crucial to have a random
4367 seed file at least for key creation, DSA signing, and for DH exchanges;
4368 for RSA signatures we could do without one.
4370 gendh and gendsa (unlike genrsa) used to read only the first byte
4371 of each file listed in the '-rand' option. The function as previously
4372 found in genrsa is now in app_rand.c and is used by all programs
4373 that support '-rand'.
4376 *) In RAND_write_file, use mode 0600 for creating files;
4377 don't just chmod when it may be too late.
4380 *) Report an error from X509_STORE_load_locations
4381 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
4384 *) New function ASN1_mbstring_copy() this copies a string in either
4385 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
4386 into an ASN1_STRING type. A mask of permissible types is passed
4387 and it chooses the "minimal" type to use or an error if not type
4391 *) Add function equivalents to the various macros in asn1.h. The old
4392 macros are retained with an M_ prefix. Code inside the library can
4393 use the M_ macros. External code (including the openssl utility)
4394 should *NOT* in order to be "shared library friendly".
4397 *) Add various functions that can check a certificate's extensions
4398 to see if it usable for various purposes such as SSL client,
4399 server or S/MIME and CAs of these types. This is currently
4400 VERY EXPERIMENTAL but will ultimately be used for certificate chain
4401 verification. Also added a -purpose flag to x509 utility to
4402 print out all the purposes.
4405 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
4409 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
4410 for, obtain and decode and extension and obtain its critical flag.
4411 This allows all the necessary extension code to be handled in a
4412 single function call.
4415 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
4416 platforms. See crypto/rc4/rc4_enc.c for further details.
4419 *) New -noout option to asn1parse. This causes no output to be produced
4420 its main use is when combined with -strparse and -out to extract data
4421 from a file (which may not be in ASN.1 format).
4424 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
4425 when producing the local key id.
4426 [Richard Levitte <levitte@stacken.kth.se>]
4428 *) New option -dhparam in s_server. This allows a DH parameter file to be
4429 stated explicitly. If it is not stated then it tries the first server
4430 certificate file. The previous behaviour hard coded the filename
4434 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
4435 a public key to be input or output. For example:
4436 openssl rsa -in key.pem -pubout -out pubkey.pem
4437 Also added necessary DSA public key functions to handle this.
4440 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
4441 in the message. This was handled by allowing
4442 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
4443 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
4445 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
4446 to the end of the strings whereas this didn't. This would cause problems
4447 if strings read with d2i_ASN1_bytes() were later modified.
4448 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
4450 *) Fix for base64 decode bug. When a base64 bio reads only one line of
4451 data and it contains EOF it will end up returning an error. This is
4452 caused by input 46 bytes long. The cause is due to the way base64
4453 BIOs find the start of base64 encoded data. They do this by trying a
4454 trial decode on each line until they find one that works. When they
4455 do a flag is set and it starts again knowing it can pass all the
4456 data directly through the decoder. Unfortunately it doesn't reset
4457 the context it uses. This means that if EOF is reached an attempt
4458 is made to pass two EOFs through the context and this causes the
4459 resulting error. This can also cause other problems as well. As is
4460 usual with these problems it takes *ages* to find and the fix is
4461 trivial: move one line.
4462 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
4464 *) Ugly workaround to get s_client and s_server working under Windows. The
4465 old code wouldn't work because it needed to select() on sockets and the
4466 tty (for keypresses and to see if data could be written). Win32 only
4467 supports select() on sockets so we select() with a 1s timeout on the
4468 sockets and then see if any characters are waiting to be read, if none
4469 are present then we retry, we also assume we can always write data to
4470 the tty. This isn't nice because the code then blocks until we've
4471 received a complete line of data and it is effectively polling the
4472 keyboard at 1s intervals: however it's quite a bit better than not
4473 working at all :-) A dedicated Windows application might handle this
4474 with an event loop for example.
4477 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
4478 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
4479 will be called when RSA_sign() and RSA_verify() are used. This is useful
4480 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
4481 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
4482 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
4483 This necessitated the support of an extra signature type NID_md5_sha1
4484 for SSL signatures and modifications to the SSL library to use it instead
4485 of calling RSA_public_decrypt() and RSA_private_encrypt().
4488 *) Add new -verify -CAfile and -CApath options to the crl program, these
4489 will lookup a CRL issuers certificate and verify the signature in a
4490 similar way to the verify program. Tidy up the crl program so it
4491 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
4492 less strict. It will now permit CRL extensions even if it is not
4493 a V2 CRL: this will allow it to tolerate some broken CRLs.
4496 *) Initialize all non-automatic variables each time one of the openssl
4497 sub-programs is started (this is necessary as they may be started
4498 multiple times from the "OpenSSL>" prompt).
4499 [Lennart Bang, Bodo Moeller]
4501 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
4502 removing all other RSA functionality (this is what NO_RSA does). This
4503 is so (for example) those in the US can disable those operations covered
4504 by the RSA patent while allowing storage and parsing of RSA keys and RSA
4508 *) Non-copying interface to BIO pairs.
4509 (still largely untested)
4512 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
4513 ASCII string. This was handled independently in various places before.
4516 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
4517 UTF8 strings a character at a time.
4520 *) Use client_version from client hello to select the protocol
4521 (s23_srvr.c) and for RSA client key exchange verification
4522 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
4525 *) Add various utility functions to handle SPKACs, these were previously
4526 handled by poking round in the structure internals. Added new function
4527 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
4528 print, verify and generate SPKACs. Based on an original idea from
4529 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
4532 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
4535 *) Allow the config file extension section to be overwritten on the
4536 command line. Based on an original idea from Massimiliano Pala
4537 <madwolf@comune.modena.it>. The new option is called -extensions
4538 and can be applied to ca, req and x509. Also -reqexts to override
4539 the request extensions in req and -crlexts to override the crl extensions
4543 *) Add new feature to the SPKAC handling in ca. Now you can include
4544 the same field multiple times by preceding it by "XXXX." for example:
4547 this is the same syntax as used in the req config file.
4550 *) Allow certificate extensions to be added to certificate requests. These
4551 are specified in a 'req_extensions' option of the req section of the
4552 config file. They can be printed out with the -text option to req but
4553 are otherwise ignored at present.
4556 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
4557 data read consists of only the final block it would not decrypted because
4558 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
4559 A misplaced 'break' also meant the decrypted final block might not be
4560 copied until the next read.
4563 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
4564 a few extra parameters to the DH structure: these will be useful if
4565 for example we want the value of 'q' or implement X9.42 DH.
4568 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
4569 provides hooks that allow the default DSA functions or functions on a
4570 "per key" basis to be replaced. This allows hardware acceleration and
4571 hardware key storage to be handled without major modification to the
4572 library. Also added low level modexp hooks and CRYPTO_EX structure and
4573 associated functions.
4576 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
4577 as "read only": it can't be written to and the buffer it points to will
4578 not be freed. Reading from a read only BIO is much more efficient than
4579 a normal memory BIO. This was added because there are several times when
4580 an area of memory needs to be read from a BIO. The previous method was
4581 to create a memory BIO and write the data to it, this results in two
4582 copies of the data and an O(n^2) reading algorithm. There is a new
4583 function BIO_new_mem_buf() which creates a read only memory BIO from
4584 an area of memory. Also modified the PKCS#7 routines to use read only
4588 *) Bugfix: ssl23_get_client_hello did not work properly when called in
4589 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
4590 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
4591 but a retry condition occured while trying to read the rest.
4594 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
4595 NID_pkcs7_encrypted by default: this was wrong since this should almost
4596 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
4597 the encrypted data type: this is a more sensible place to put it and it
4598 allows the PKCS#12 code to be tidied up that duplicated this
4602 *) Changed obj_dat.pl script so it takes its input and output files on
4603 the command line. This should avoid shell escape redirection problems
4607 *) Initial support for certificate extension requests, these are included
4608 in things like Xenroll certificate requests. Included functions to allow
4609 extensions to be obtained and added.
4612 *) -crlf option to s_client and s_server for sending newlines as
4613 CRLF (as required by many protocols).
4616 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
4618 *) Install libRSAglue.a when OpenSSL is built with RSAref.
4619 [Ralf S. Engelschall]
4621 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
4622 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
4624 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
4628 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
4629 DH parameters/keys (q is lost during that conversion, but the resulting
4630 DH parameters contain its length).
4632 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
4633 much faster than DH_generate_parameters (which creates parameters
4634 where p = 2*q + 1), and also the smaller q makes DH computations
4635 much more efficient (160-bit exponentiation instead of 1024-bit
4636 exponentiation); so this provides a convenient way to support DHE
4637 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
4638 utter importance to use
4639 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
4641 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
4642 when such DH parameters are used, because otherwise small subgroup
4643 attacks may become possible!
4646 *) Avoid memory leak in i2d_DHparams.
4649 *) Allow the -k option to be used more than once in the enc program:
4650 this allows the same encrypted message to be read by multiple recipients.
4653 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
4654 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
4655 it will always use the numerical form of the OID, even if it has a short
4659 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
4660 method only got called if p,q,dmp1,dmq1,iqmp components were present,
4661 otherwise bn_mod_exp was called. In the case of hardware keys for example
4662 no private key components need be present and it might store extra data
4663 in the RSA structure, which cannot be accessed from bn_mod_exp.
4664 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
4665 private key operations.
4668 *) Added support for SPARC Linux.
4671 *) pem_password_cb function type incompatibly changed from
4672 typedef int pem_password_cb(char *buf, int size, int rwflag);
4674 ....(char *buf, int size, int rwflag, void *userdata);
4675 so that applications can pass data to their callbacks:
4676 The PEM[_ASN1]_{read,write}... functions and macros now take an
4677 additional void * argument, which is just handed through whenever
4678 the password callback is called.
4679 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
4681 New function SSL_CTX_set_default_passwd_cb_userdata.
4683 Compatibility note: As many C implementations push function arguments
4684 onto the stack in reverse order, the new library version is likely to
4685 interoperate with programs that have been compiled with the old
4686 pem_password_cb definition (PEM_whatever takes some data that
4687 happens to be on the stack as its last argument, and the callback
4688 just ignores this garbage); but there is no guarantee whatsoever that
4691 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
4692 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
4693 problems not only on Windows, but also on some Unix platforms.
4694 To avoid problematic command lines, these definitions are now in an
4695 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
4696 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
4699 *) MIPS III/IV assembler module is reimplemented.
4702 *) More DES library cleanups: remove references to srand/rand and
4703 delete an unused file.
4706 *) Add support for the the free Netwide assembler (NASM) under Win32,
4707 since not many people have MASM (ml) and it can be hard to obtain.
4708 This is currently experimental but it seems to work OK and pass all
4709 the tests. Check out INSTALL.W32 for info.
4712 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
4713 without temporary keys kept an extra copy of the server key,
4714 and connections with temporary keys did not free everything in case
4718 *) New function RSA_check_key and new openssl rsa option -check
4719 for verifying the consistency of RSA keys.
4720 [Ulf Moeller, Bodo Moeller]
4722 *) Various changes to make Win32 compile work:
4723 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
4724 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
4725 comparison" warnings.
4726 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
4729 *) Add a debugging option to PKCS#5 v2 key generation function: when
4730 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
4731 derived keys are printed to stderr.
4734 *) Copy the flags in ASN1_STRING_dup().
4735 [Roman E. Pavlov <pre@mo.msk.ru>]
4737 *) The x509 application mishandled signing requests containing DSA
4738 keys when the signing key was also DSA and the parameters didn't match.
4740 It was supposed to omit the parameters when they matched the signing key:
4741 the verifying software was then supposed to automatically use the CA's
4742 parameters if they were absent from the end user certificate.
4744 Omitting parameters is no longer recommended. The test was also
4745 the wrong way round! This was probably due to unusual behaviour in
4746 EVP_cmp_parameters() which returns 1 if the parameters match.
4747 This meant that parameters were omitted when they *didn't* match and
4748 the certificate was useless. Certificates signed with 'ca' didn't have
4750 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
4752 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
4753 The interface is as follows:
4754 Applications can use
4755 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
4756 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
4757 "off" is now the default.
4758 The library internally uses
4759 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
4760 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
4761 to disable memory-checking temporarily.
4763 Some inconsistent states that previously were possible (and were
4764 even the default) are now avoided.
4766 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
4767 with each memory chunk allocated; this is occasionally more helpful
4768 than just having a counter.
4770 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
4772 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
4776 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
4777 which largely parallels "options", but is for changing API behaviour,
4778 whereas "options" are about protocol behaviour.
4779 Initial "mode" flags are:
4781 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
4782 a single record has been written.
4783 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
4784 retries use the same buffer location.
4785 (But all of the contents must be
4789 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
4792 *) Fix problems with no-hmac etc.
4793 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
4795 *) New functions RSA_get_default_method(), RSA_set_method() and
4796 RSA_get_method(). These allows replacement of RSA_METHODs without having
4797 to mess around with the internals of an RSA structure.
4800 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
4801 Also really enable memory leak checks in openssl.c and in some
4803 [Chad C. Mulligan, Bodo Moeller]
4805 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
4806 up the length of negative integers. This has now been simplified to just
4807 store the length when it is first determined and use it later, rather
4808 than trying to keep track of where data is copied and updating it to
4810 [Steve Henson, reported by Brien Wheeler
4811 <bwheeler@authentica-security.com>]
4813 *) Add a new function PKCS7_signatureVerify. This allows the verification
4814 of a PKCS#7 signature but with the signing certificate passed to the
4815 function itself. This contrasts with PKCS7_dataVerify which assumes the
4816 certificate is present in the PKCS#7 structure. This isn't always the
4817 case: certificates can be omitted from a PKCS#7 structure and be
4818 distributed by "out of band" means (such as a certificate database).
4821 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
4822 function prototypes in pem.h, also change util/mkdef.pl to add the
4823 necessary function names.
4826 *) mk1mf.pl (used by Windows builds) did not properly read the
4827 options set by Configure in the top level Makefile, and Configure
4828 was not even able to write more than one option correctly.
4829 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
4832 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
4833 file to be loaded from a BIO or FILE pointer. The BIO version will
4834 for example allow memory BIOs to contain config info.
4837 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
4838 Whoever hopes to achieve shared-library compatibility across versions
4839 must use this, not the compile-time macro.
4840 (Exercise 0.9.4: Which is the minimum library version required by
4842 Note: All this applies only to multi-threaded programs, others don't
4846 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
4847 through a BIO pair triggered the default case, i.e.
4848 SSLerr(...,SSL_R_UNKNOWN_STATE).
4851 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
4852 can use the SSL library even if none of the specific BIOs is
4856 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
4857 for the encoded length.
4858 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
4860 *) Add initial documentation of the X509V3 functions.
4863 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
4864 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
4865 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
4866 secure PKCS#8 private key format with a high iteration count.
4869 *) Fix determination of Perl interpreter: A perl or perl5
4870 _directory_ in $PATH was also accepted as the interpreter.
4871 [Ralf S. Engelschall]
4873 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
4874 wrong with it but it was very old and did things like calling
4875 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
4879 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
4880 to use the new extension code.
4883 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
4884 with macros. This should make it easier to change their form, add extra
4885 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
4889 *) Add to configuration table a new entry that can specify an alternative
4890 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
4891 according to Mark Crispin <MRC@Panda.COM>.
4895 *) DES CBC did not update the IV. Weird.
4898 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
4899 Changing the behaviour of the former might break existing programs --
4900 where IV updating is needed, des_ncbc_encrypt can be used.
4903 *) When bntest is run from "make test" it drives bc to check its
4904 calculations, as well as internally checking them. If an internal check
4905 fails, it needs to cause bc to give a non-zero result or make test carries
4906 on without noticing the failure. Fixed.
4909 *) DES library cleanups.
4912 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
4913 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
4914 ciphers. NOTE: although the key derivation function has been verified
4915 against some published test vectors it has not been extensively tested
4916 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
4920 *) Instead of "mkdir -p", which is not fully portable, use new
4921 Perl script "util/mkdir-p.pl".
4924 *) Rewrite the way password based encryption (PBE) is handled. It used to
4925 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
4926 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
4927 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
4928 the 'parameter' field of the AlgorithmIdentifier is passed to the
4929 underlying key generation function so it must do its own ASN1 parsing.
4930 This has also changed the EVP_PBE_CipherInit() function which now has a
4931 'parameter' argument instead of literal salt and iteration count values
4932 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
4935 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
4936 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
4937 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
4938 KEY" because this clashed with PKCS#8 unencrypted string. Since this
4939 value was just used as a "magic string" and not used directly its
4940 value doesn't matter.
4943 *) Introduce some semblance of const correctness to BN. Shame C doesn't
4947 *) "linux-sparc64" configuration (ultrapenguin).
4948 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
4949 "linux-sparc" configuration.
4950 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
4952 *) config now generates no-xxx options for missing ciphers.
4955 *) Support the EBCDIC character set (work in progress).
4956 File ebcdic.c not yet included because it has a different license.
4957 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4959 *) Support BS2000/OSD-POSIX.
4960 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
4962 *) Make callbacks for key generation use void * instead of char *.
4965 *) Make S/MIME samples compile (not yet tested).
4968 *) Additional typesafe stacks.
4971 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
4975 Changes between 0.9.3 and 0.9.3a [29 May 1999]
4977 *) New configuration variant "sco5-gcc".
4979 *) Updated some demos.
4980 [Sean O Riordain, Wade Scholine]
4982 *) Add missing BIO_free at exit of pkcs12 application.
4985 *) Fix memory leak in conf.c.
4988 *) Updates for Win32 to assembler version of MD5.
4991 *) Set #! path to perl in apps/der_chop to where we found it
4992 instead of using a fixed path.
4995 *) SHA library changes for irix64-mips4-cc.
4998 *) Improvements for VMS support.
5002 Changes between 0.9.2b and 0.9.3 [24 May 1999]
5004 *) Bignum library bug fix. IRIX 6 passes "make test" now!
5005 This also avoids the problems with SC4.2 and unpatched SC5.
5006 [Andy Polyakov <appro@fy.chalmers.se>]
5008 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
5009 These are required because of the typesafe stack would otherwise break
5010 existing code. If old code used a structure member which used to be STACK
5011 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
5012 sk_num or sk_value it would produce an error because the num, data members
5013 are not present in STACK_OF. Now it just produces a warning. sk_set
5014 replaces the old method of assigning a value to sk_value
5015 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
5016 that does this will no longer work (and should use sk_set instead) but
5017 this could be regarded as a "questionable" behaviour anyway.
5020 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
5021 correctly handle encrypted S/MIME data.
5024 *) Change type of various DES function arguments from des_cblock
5025 (which means, in function argument declarations, pointer to char)
5026 to des_cblock * (meaning pointer to array with 8 char elements),
5027 which allows the compiler to do more typechecking; it was like
5028 that back in SSLeay, but with lots of ugly casts.
5030 Introduce new type const_des_cblock.
5033 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
5034 problems: find RecipientInfo structure that matches recipient certificate
5035 and initialise the ASN1 structures properly based on passed cipher.
5038 *) Belatedly make the BN tests actually check the results.
5041 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
5042 to and from BNs: it was completely broken. New compilation option
5043 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
5044 key elements as negative integers.
5047 *) Reorganize and speed up MD5.
5048 [Andy Polyakov <appro@fy.chalmers.se>]
5051 [Richard Levitte <richard@levitte.org>]
5053 *) New option -out to asn1parse to allow the parsed structure to be
5054 output to a file. This is most useful when combined with the -strparse
5055 option to examine the output of things like OCTET STRINGS.
5058 *) Make SSL library a little more fool-proof by not requiring any longer
5059 that SSL_set_{accept,connect}_state be called before
5060 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
5061 in many applications because usually everything *appeared* to work as
5062 intended anyway -- now it really works as intended).
5065 *) Move openssl.cnf out of lib/.
5068 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
5069 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
5070 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
5071 [Ralf S. Engelschall]
5073 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
5074 handle PKCS#7 enveloped data properly.
5075 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
5077 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
5078 copying pointers. The cert_st handling is changed by this in
5079 various ways (and thus what used to be known as ctx->default_cert
5080 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
5081 any longer when s->cert does not give us what we need).
5082 ssl_cert_instantiate becomes obsolete by this change.
5083 As soon as we've got the new code right (possibly it already is?),
5084 we have solved a couple of bugs of the earlier code where s->cert
5085 was used as if it could not have been shared with other SSL structures.
5087 Note that using the SSL API in certain dirty ways now will result
5088 in different behaviour than observed with earlier library versions:
5089 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
5090 does not influence s as it used to.
5092 In order to clean up things more thoroughly, inside SSL_SESSION
5093 we don't use CERT any longer, but a new structure SESS_CERT
5094 that holds per-session data (if available); currently, this is
5095 the peer's certificate chain and, for clients, the server's certificate
5096 and temporary key. CERT holds only those values that can have
5097 meaningful defaults in an SSL_CTX.
5100 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
5101 from the internal representation. Various PKCS#7 fixes: remove some
5102 evil casts and set the enc_dig_alg field properly based on the signing
5106 *) Allow PKCS#12 password to be set from the command line or the
5107 environment. Let 'ca' get its config file name from the environment
5108 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
5112 *) Allow certificate policies extension to use an IA5STRING for the
5113 organization field. This is contrary to the PKIX definition but
5114 VeriSign uses it and IE5 only recognises this form. Document 'x509'
5118 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
5119 without disallowing inline assembler and the like for non-pedantic builds.
5122 *) Support Borland C++ builder.
5123 [Janez Jere <jj@void.si>, modified by Ulf Möller]
5128 *) SHA-1 cleanups and performance enhancements.
5129 [Andy Polyakov <appro@fy.chalmers.se>]
5131 *) Sparc v8plus assembler for the bignum library.
5132 [Andy Polyakov <appro@fy.chalmers.se>]
5134 *) Accept any -xxx and +xxx compiler options in Configure.
5137 *) Update HPUX configuration.
5140 *) Add missing sk_<type>_unshift() function to safestack.h
5141 [Ralf S. Engelschall]
5143 *) New function SSL_CTX_use_certificate_chain_file that sets the
5144 "extra_cert"s in addition to the certificate. (This makes sense
5145 only for "PEM" format files, as chains as a whole are not
5149 *) Support verify_depth from the SSL API.
5150 x509_vfy.c had what can be considered an off-by-one-error:
5151 Its depth (which was not part of the external interface)
5152 was actually counting the number of certificates in a chain;
5153 now it really counts the depth.
5156 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
5157 instead of X509err, which often resulted in confusing error
5158 messages since the error codes are not globally unique
5159 (e.g. an alleged error in ssl3_accept when a certificate
5160 didn't match the private key).
5162 *) New function SSL_CTX_set_session_id_context that allows to set a default
5163 value (so that you don't need SSL_set_session_id_context for each
5164 connection using the SSL_CTX).
5167 *) OAEP decoding bug fix.
5170 *) Support INSTALL_PREFIX for package builders, as proposed by
5174 *) New Configure options "threads" and "no-threads". For systems
5175 where the proper compiler options are known (currently Solaris
5176 and Linux), "threads" is the default.
5179 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
5182 *) Install various scripts to $(OPENSSLDIR)/misc, not to
5183 $(INSTALLTOP)/bin -- they shouldn't clutter directories
5184 such as /usr/local/bin.
5187 *) "make linux-shared" to build shared libraries.
5188 [Niels Poppe <niels@netbox.org>]
5190 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
5193 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
5194 extension adding in x509 utility.
5197 *) Remove NOPROTO sections and error code comments.
5200 *) Partial rewrite of the DEF file generator to now parse the ANSI
5204 *) New Configure options --prefix=DIR and --openssldir=DIR.
5207 *) Complete rewrite of the error code script(s). It is all now handled
5208 by one script at the top level which handles error code gathering,
5209 header rewriting and C source file generation. It should be much better
5210 than the old method: it now uses a modified version of Ulf's parser to
5211 read the ANSI prototypes in all header files (thus the old K&R definitions
5212 aren't needed for error creation any more) and do a better job of
5213 translating function codes into names. The old 'ASN1 error code imbedded
5214 in a comment' is no longer necessary and it doesn't use .err files which
5215 have now been deleted. Also the error code call doesn't have to appear all
5216 on one line (which resulted in some large lines...).
5219 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
5222 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
5223 0 (which usually indicates a closed connection), but continue reading.
5226 *) Fix some race conditions.
5229 *) Add support for CRL distribution points extension. Add Certificate
5230 Policies and CRL distribution points documentation.
5233 *) Move the autogenerated header file parts to crypto/opensslconf.h.
5236 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
5237 8 of keying material. Merlin has also confirmed interop with this fix
5238 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
5239 [Merlin Hughes <merlin@baltimore.ie>]
5241 *) Fix lots of warnings.
5242 [Richard Levitte <levitte@stacken.kth.se>]
5244 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
5245 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
5246 [Richard Levitte <levitte@stacken.kth.se>]
5248 *) Fix problems with sizeof(long) == 8.
5249 [Andy Polyakov <appro@fy.chalmers.se>]
5251 *) Change functions to ANSI C.
5254 *) Fix typos in error codes.
5255 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
5257 *) Remove defunct assembler files from Configure.
5260 *) SPARC v8 assembler BIGNUM implementation.
5261 [Andy Polyakov <appro@fy.chalmers.se>]
5263 *) Support for Certificate Policies extension: both print and set.
5264 Various additions to support the r2i method this uses.
5267 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
5268 return a const string when you are expecting an allocated buffer.
5271 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
5272 types DirectoryString and DisplayText.
5275 *) Add code to allow r2i extensions to access the configuration database,
5276 add an LHASH database driver and add several ctx helper functions.
5279 *) Fix an evil bug in bn_expand2() which caused various BN functions to
5280 fail when they extended the size of a BIGNUM.
5283 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
5284 support typesafe stack.
5287 *) Fix typo in SSL_[gs]et_options().
5288 [Nils Frostberg <nils@medcom.se>]
5290 *) Delete various functions and files that belonged to the (now obsolete)
5291 old X509V3 handling code.
5294 *) New Configure option "rsaref".
5297 *) Don't auto-generate pem.h.
5300 *) Introduce type-safe ASN.1 SETs.
5303 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
5304 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
5306 *) Introduce type-safe STACKs. This will almost certainly break lots of code
5307 that links with OpenSSL (well at least cause lots of warnings), but fear
5308 not: the conversion is trivial, and it eliminates loads of evil casts. A
5309 few STACKed things have been converted already. Feel free to convert more.
5310 In the fullness of time, I'll do away with the STACK type altogether.
5313 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
5314 specified in <certfile> by updating the entry in the index.txt file.
5315 This way one no longer has to edit the index.txt file manually for
5316 revoking a certificate. The -revoke option does the gory details now.
5317 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
5319 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
5320 `-text' option at all and this way the `-noout -text' combination was
5321 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
5322 [Ralf S. Engelschall]
5324 *) Make sure a corresponding plain text error message exists for the
5325 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
5326 verify callback function determined that a certificate was revoked.
5327 [Ralf S. Engelschall]
5329 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
5330 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
5331 all available cipers including rc5, which was forgotten until now.
5332 In order to let the testing shell script know which algorithms
5333 are available, a new (up to now undocumented) command
5334 "openssl list-cipher-commands" is used.
5337 *) Bugfix: s_client occasionally would sleep in select() when
5338 it should have checked SSL_pending() first.
5341 *) New functions DSA_do_sign and DSA_do_verify to provide access to
5342 the raw DSA values prior to ASN.1 encoding.
5345 *) Tweaks to Configure
5346 [Niels Poppe <niels@netbox.org>]
5348 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
5352 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
5355 *) New config option to avoid instructions that are illegal on the 80386.
5356 The default code is faster, but requires at least a 486.
5359 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
5360 SSL2_SERVER_VERSION (not used at all) macros, which are now the
5361 same as SSL2_VERSION anyway.
5364 *) New "-showcerts" option for s_client.
5367 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
5368 application. Various cleanups and fixes.
5371 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
5372 modify error routines to work internally. Add error codes and PBE init
5373 to library startup routines.
5376 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
5377 packing functions to asn1 and evp. Changed function names and error
5378 codes along the way.
5381 *) PKCS12 integration: and so it begins... First of several patches to
5382 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
5383 objects to objects.h
5386 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
5387 and display support for Thawte strong extranet extension.
5390 *) Add LinuxPPC support.
5391 [Jeff Dubrule <igor@pobox.org>]
5393 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
5394 bn_div_words in alpha.s.
5395 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
5397 *) Make sure the RSA OAEP test is skipped under -DRSAref because
5398 OAEP isn't supported when OpenSSL is built with RSAref.
5399 [Ulf Moeller <ulf@fitug.de>]
5401 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
5402 so they no longer are missing under -DNOPROTO.
5403 [Soren S. Jorvang <soren@t.dk>]
5406 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
5408 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
5409 doesn't work when the session is reused. Coming soon!
5412 *) Fix a security hole, that allows sessions to be reused in the wrong
5413 context thus bypassing client cert protection! All software that uses
5414 client certs and session caches in multiple contexts NEEDS PATCHING to
5415 allow session reuse! A fuller solution is in the works.
5416 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
5418 *) Some more source tree cleanups (removed obsolete files
5419 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
5420 permission on "config" script to be executable) and a fix for the INSTALL
5422 [Ulf Moeller <ulf@fitug.de>]
5424 *) Remove some legacy and erroneous uses of malloc, free instead of
5426 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
5428 *) Make rsa_oaep_test return non-zero on error.
5429 [Ulf Moeller <ulf@fitug.de>]
5431 *) Add support for native Solaris shared libraries. Configure
5432 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
5433 if someone would make that last step automatic.
5434 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
5436 *) ctx_size was not built with the right compiler during "make links". Fixed.
5439 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
5440 except NULL ciphers". This means the default cipher list will no longer
5441 enable NULL ciphers. They need to be specifically enabled e.g. with
5442 the string "DEFAULT:eNULL".
5445 *) Fix to RSA private encryption routines: if p < q then it would
5446 occasionally produce an invalid result. This will only happen with
5447 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
5450 *) Be less restrictive and allow also `perl util/perlpath.pl
5451 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
5452 because this way one can also use an interpreter named `perl5' (which is
5453 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
5454 installed as `perl').
5455 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5457 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
5458 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5460 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
5461 advapi32.lib to Win32 build and change the pem test comparision
5462 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
5463 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
5464 and crypto/des/ede_cbcm_enc.c.
5467 *) DES quad checksum was broken on big-endian architectures. Fixed.
5470 *) Comment out two functions in bio.h that aren't implemented. Fix up the
5471 Win32 test batch file so it (might) work again. The Win32 test batch file
5472 is horrible: I feel ill....
5475 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
5476 in e_os.h. Audit of header files to check ANSI and non ANSI
5477 sections: 10 functions were absent from non ANSI section and not exported
5478 from Windows DLLs. Fixed up libeay.num for new functions.
5481 *) Make `openssl version' output lines consistent.
5482 [Ralf S. Engelschall]
5484 *) Fix Win32 symbol export lists for BIO functions: Added
5485 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
5486 to ms/libeay{16,32}.def.
5487 [Ralf S. Engelschall]
5489 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
5490 fine under Unix and passes some trivial tests I've now added. But the
5491 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
5492 added to make sure no one expects that this stuff really works in the
5493 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
5494 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
5496 [Ralf S. Engelschall]
5498 *) Fix the generation of two part addresses in perl.
5499 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
5501 *) Add config entry for Linux on MIPS.
5502 [John Tobey <jtobey@channel1.com>]
5504 *) Make links whenever Configure is run, unless we are on Windoze.
5507 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
5508 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
5512 *) Add a useful kludge to allow package maintainers to specify compiler and
5513 other platforms details on the command line without having to patch the
5514 Configure script everytime: One now can use ``perl Configure
5515 <id>:<details>'', i.e. platform ids are allowed to have details appended
5516 to them (seperated by colons). This is treated as there would be a static
5517 pre-configured entry in Configure's %table under key <id> with value
5518 <details> and ``perl Configure <id>'' is called. So, when you want to
5519 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
5520 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
5521 now, which overrides the FreeBSD-elf entry on-the-fly.
5522 [Ralf S. Engelschall]
5524 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
5527 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
5528 on the `perl Configure ...' command line. This way one can compile
5529 OpenSSL libraries with Position Independent Code (PIC) which is needed
5530 for linking it into DSOs.
5531 [Ralf S. Engelschall]
5533 *) Remarkably, export ciphers were totally broken and no-one had noticed!
5537 *) Cleaned up the LICENSE document: The official contact for any license
5538 questions now is the OpenSSL core team under openssl-core@openssl.org.
5539 And add a paragraph about the dual-license situation to make sure people
5540 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
5541 to the OpenSSL toolkit.
5542 [Ralf S. Engelschall]
5544 *) General source tree makefile cleanups: Made `making xxx in yyy...'
5545 display consistent in the source tree and replaced `/bin/rm' by `rm'.
5546 Additonally cleaned up the `make links' target: Remove unnecessary
5547 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
5548 to speed processing and no longer clutter the display with confusing
5549 stuff. Instead only the actually done links are displayed.
5550 [Ralf S. Engelschall]
5552 *) Permit null encryption ciphersuites, used for authentication only. It used
5553 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
5554 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
5558 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
5559 signed attributes when verifying signatures (this would break them),
5560 the detached data encoding was wrong and public keys obtained using
5561 X509_get_pubkey() weren't freed.
5564 *) Add text documentation for the BUFFER functions. Also added a work around
5565 to a Win95 console bug. This was triggered by the password read stuff: the
5566 last character typed gets carried over to the next fread(). If you were
5567 generating a new cert request using 'req' for example then the last
5568 character of the passphrase would be CR which would then enter the first
5572 *) Added the new `Includes OpenSSL Cryptography Software' button as
5573 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
5574 button and can be used by applications based on OpenSSL to show the
5575 relationship to the OpenSSL project.
5576 [Ralf S. Engelschall]
5578 *) Remove confusing variables in function signatures in files
5579 ssl/ssl_lib.c and ssl/ssl.h.
5580 [Lennart Bong <lob@kulthea.stacken.kth.se>]
5582 *) Don't install bss_file.c under PREFIX/include/
5583 [Lennart Bong <lob@kulthea.stacken.kth.se>]
5585 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
5586 functions that return function pointers and has support for NT specific
5587 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
5588 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
5589 unsigned to signed types: this was killing the Win32 compile.
5592 *) Add new certificate file to stack functions,
5593 SSL_add_dir_cert_subjects_to_stack() and
5594 SSL_add_file_cert_subjects_to_stack(). These largely supplant
5595 SSL_load_client_CA_file(), and can be used to add multiple certs easily
5596 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
5597 This means that Apache-SSL and similar packages don't have to mess around
5598 to add as many CAs as they want to the preferred list.
5601 *) Experiment with doxygen documentation. Currently only partially applied to
5603 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
5604 openssl.doxy as the configuration file.
5607 *) Get rid of remaining C++-style comments which strict C compilers hate.
5608 [Ralf S. Engelschall, pointed out by Carlos Amengual]
5610 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
5611 compiled in by default: it has problems with large keys.
5614 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
5615 DH private keys and/or callback functions which directly correspond to
5616 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
5617 is needed for applications which have to configure certificates on a
5618 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
5620 For the RSA certificate situation is makes no difference, but
5621 for the DSA certificate situation this fixes the "no shared cipher"
5622 problem where the OpenSSL cipher selection procedure failed because the
5623 temporary keys were not overtaken from the context and the API provided
5624 no way to reconfigure them.
5625 The new functions now let applications reconfigure the stuff and they
5626 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
5627 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
5628 non-public-API function ssl_cert_instantiate() is used as a helper
5629 function and also to reduce code redundancy inside ssl_rsa.c.
5630 [Ralf S. Engelschall]
5632 *) Move s_server -dcert and -dkey options out of the undocumented feature
5633 area because they are useful for the DSA situation and should be
5634 recognized by the users.
5635 [Ralf S. Engelschall]
5637 *) Fix the cipher decision scheme for export ciphers: the export bits are
5638 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
5639 SSL_EXP_MASK. So, the original variable has to be used instead of the
5640 already masked variable.
5641 [Richard Levitte <levitte@stacken.kth.se>]
5643 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
5644 [Richard Levitte <levitte@stacken.kth.se>]
5646 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
5647 from `int' to `unsigned int' because it's a length and initialized by
5648 EVP_DigestFinal() which expects an `unsigned int *'.
5649 [Richard Levitte <levitte@stacken.kth.se>]
5651 *) Don't hard-code path to Perl interpreter on shebang line of Configure
5652 script. Instead use the usual Shell->Perl transition trick.
5653 [Ralf S. Engelschall]
5655 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
5656 (in addition to RSA certificates) to match the behaviour of `openssl dsa
5657 -noout -modulus' as it's already the case for `openssl rsa -noout
5658 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
5659 currently the public key is printed (a decision which was already done by
5660 `openssl dsa -modulus' in the past) which serves a similar purpose.
5661 Additionally the NO_RSA no longer completely removes the whole -modulus
5662 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
5664 [Ralf S. Engelschall]
5666 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
5667 BIO. See the source (crypto/evp/bio_ok.c) for more info.
5668 [Arne Ansper <arne@ats.cyber.ee>]
5670 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
5671 to be added. Now both 'req' and 'ca' can use new objects defined in the
5675 *) Add cool BIO that does syslog (or event log on NT).
5676 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
5678 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
5679 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
5680 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
5681 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
5684 *) Add preliminary config info for new extension code.
5687 *) Make RSA_NO_PADDING really use no padding.
5688 [Ulf Moeller <ulf@fitug.de>]
5690 *) Generate errors when private/public key check is done.
5693 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
5694 for some CRL extensions and new objects added.
5697 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
5698 key usage extension and fuller support for authority key id.
5701 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
5702 padding method for RSA, which is recommended for new applications in PKCS
5703 #1 v2.0 (RFC 2437, October 1998).
5704 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
5705 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
5706 against Bleichbacher's attack on RSA.
5707 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
5710 *) Updates to the new SSL compression code
5711 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5713 *) Fix so that the version number in the master secret, when passed
5714 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
5715 (because the server will not accept higher), that the version number
5716 is 0x03,0x01, not 0x03,0x00
5717 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5719 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
5720 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
5721 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
5724 *) Support for RAW extensions where an arbitrary extension can be
5725 created by including its DER encoding. See apps/openssl.cnf for
5729 *) Make sure latest Perl versions don't interpret some generated C array
5730 code as Perl array code in the crypto/err/err_genc.pl script.
5731 [Lars Weber <3weber@informatik.uni-hamburg.de>]
5733 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
5734 not many people have the assembler. Various Win32 compilation fixes and
5735 update to the INSTALL.W32 file with (hopefully) more accurate Win32
5739 *) Modify configure script 'Configure' to automatically create crypto/date.h
5740 file under Win32 and also build pem.h from pem.org. New script
5741 util/mkfiles.pl to create the MINFO file on environments that can't do a
5742 'make files': perl util/mkfiles.pl >MINFO should work.
5745 *) Major rework of DES function declarations, in the pursuit of correctness
5746 and purity. As a result, many evil casts evaporated, and some weirdness,
5747 too. You may find this causes warnings in your code. Zapping your evil
5748 casts will probably fix them. Mostly.
5751 *) Fix for a typo in asn1.h. Bug fix to object creation script
5752 obj_dat.pl. It considered a zero in an object definition to mean
5753 "end of object": none of the objects in objects.h have any zeros
5754 so it wasn't spotted.
5755 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
5757 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
5758 Masking (CBCM). In the absence of test vectors, the best I have been able
5759 to do is check that the decrypt undoes the encrypt, so far. Send me test
5760 vectors if you have them.
5763 *) Correct calculation of key length for export ciphers (too much space was
5764 allocated for null ciphers). This has not been tested!
5767 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
5768 message is now correct (it understands "crypto" and "ssl" on its
5769 command line). There is also now an "update" option. This will update
5770 the util/ssleay.num and util/libeay.num files with any new functions.
5772 perl util/mkdef.pl crypto ssl update
5773 it will update them.
5776 *) Overhauled the Perl interface (perl/*):
5777 - ported BN stuff to OpenSSL's different BN library
5778 - made the perl/ source tree CVS-aware
5779 - renamed the package from SSLeay to OpenSSL (the files still contain
5780 their history because I've copied them in the repository)
5781 - removed obsolete files (the test scripts will be replaced
5782 by better Test::Harness variants in the future)
5783 [Ralf S. Engelschall]
5785 *) First cut for a very conservative source tree cleanup:
5786 1. merge various obsolete readme texts into doc/ssleay.txt
5787 where we collect the old documents and readme texts.
5788 2. remove the first part of files where I'm already sure that we no
5789 longer need them because of three reasons: either they are just temporary
5790 files which were left by Eric or they are preserved original files where
5791 I've verified that the diff is also available in the CVS via "cvs diff
5792 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
5793 the crypto/md/ stuff).
5794 [Ralf S. Engelschall]
5796 *) More extension code. Incomplete support for subject and issuer alt
5797 name, issuer and authority key id. Change the i2v function parameters
5798 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
5799 what that's for :-) Fix to ASN1 macro which messed up
5800 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
5803 *) Preliminary support for ENUMERATED type. This is largely copied from the
5807 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
5808 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5810 *) Make sure `make rehash' target really finds the `openssl' program.
5811 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5813 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
5814 like to hear about it if this slows down other processors.
5817 *) Add CygWin32 platform information to Configure script.
5818 [Alan Batie <batie@aahz.jf.intel.com>]
5820 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
5821 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
5823 *) New program nseq to manipulate netscape certificate sequences
5826 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
5830 *) Fixes to BN code. Previously the default was to define BN_RECURSION
5831 but the BN code had some problems that would cause failures when
5832 doing certificate verification and some other functions.
5833 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
5835 *) Add ASN1 and PEM code to support netscape certificate sequences.
5838 *) Add ASN1 and PEM code to support netscape certificate sequences.
5841 *) Add several PKIX and private extended key usage OIDs.
5844 *) Modify the 'ca' program to handle the new extension code. Modify
5845 openssl.cnf for new extension format, add comments.
5848 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
5849 and add a sample to openssl.cnf so req -x509 now adds appropriate
5853 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
5854 error code, add initial support to X509_print() and x509 application.
5857 *) Takes a deep breath and start addding X509 V3 extension support code. Add
5858 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
5859 stuff is currently isolated and isn't even compiled yet.
5862 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
5863 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
5864 Removed the versions check from X509 routines when loading extensions:
5865 this allows certain broken certificates that don't set the version
5866 properly to be processed.
5869 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
5870 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
5871 can still be regenerated with "make depend".
5874 *) Spelling mistake in C version of CAST-128.
5875 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
5877 *) Changes to the error generation code. The perl script err-code.pl
5878 now reads in the old error codes and retains the old numbers, only
5879 adding new ones if necessary. It also only changes the .err files if new
5880 codes are added. The makefiles have been modified to only insert errors
5881 when needed (to avoid needlessly modifying header files). This is done
5882 by only inserting errors if the .err file is newer than the auto generated
5883 C file. To rebuild all the error codes from scratch (the old behaviour)
5884 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
5885 or delete all the .err files.
5888 *) CAST-128 was incorrectly implemented for short keys. The C version has
5889 been fixed, but is untested. The assembler versions are also fixed, but
5890 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
5891 to regenerate it if needed.
5892 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
5893 Hagino <itojun@kame.net>]
5895 *) File was opened incorrectly in randfile.c.
5896 [Ulf Möller <ulf@fitug.de>]
5898 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
5899 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
5900 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
5901 al: it's just almost always a UTCTime. Note this patch adds new error
5902 codes so do a "make errors" if there are problems.
5905 *) Correct Linux 1 recognition in config.
5906 [Ulf Möller <ulf@fitug.de>]
5908 *) Remove pointless MD5 hash when using DSA keys in ca.
5909 [Anonymous <nobody@replay.com>]
5911 *) Generate an error if given an empty string as a cert directory. Also
5912 generate an error if handed NULL (previously returned 0 to indicate an
5913 error, but didn't set one).
5914 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
5916 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
5919 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
5920 parameters. This was causing a warning which killed off the Win32 compile.
5923 *) Remove C++ style comments from crypto/bn/bn_local.h.
5924 [Neil Costigan <neil.costigan@celocom.com>]
5926 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
5927 based on a text string, looking up short and long names and finally
5928 "dot" format. The "dot" format stuff didn't work. Added new function
5929 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
5930 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
5931 OID is not part of the table.
5934 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
5935 X509_LOOKUP_by_alias().
5938 *) Sort openssl functions by name.
5941 *) Get the gendsa program working (hopefully) and add it to app list. Remove
5942 encryption from sample DSA keys (in case anyone is interested the password
5946 *) Make _all_ *_free functions accept a NULL pointer.
5947 [Frans Heymans <fheymans@isaserver.be>]
5949 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
5951 [Anonymous <nobody@replay.com>]
5953 *) s_server should send the CAfile as acceptable CAs, not its own cert.
5954 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5956 *) Don't blow it for numeric -newkey arguments to apps/req.
5957 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
5959 *) Temp key "for export" tests were wrong in s3_srvr.c.
5960 [Anonymous <nobody@replay.com>]
5962 *) Add prototype for temp key callback functions
5963 SSL_CTX_set_tmp_{rsa,dh}_callback().
5966 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
5967 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
5970 *) X509_name_add_entry() freed the wrong thing after an error.
5971 [Arne Ansper <arne@ats.cyber.ee>]
5973 *) rsa_eay.c would attempt to free a NULL context.
5974 [Arne Ansper <arne@ats.cyber.ee>]
5976 *) BIO_s_socket() had a broken should_retry() on Windoze.
5977 [Arne Ansper <arne@ats.cyber.ee>]
5979 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
5980 [Arne Ansper <arne@ats.cyber.ee>]
5982 *) Make sure the already existing X509_STORE->depth variable is initialized
5983 in X509_STORE_new(), but document the fact that this variable is still
5984 unused in the certificate verification process.
5985 [Ralf S. Engelschall]
5987 *) Fix the various library and apps files to free up pkeys obtained from
5988 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
5991 *) Fix reference counting in X509_PUBKEY_get(). This makes
5992 demos/maurice/example2.c work, amongst others, probably.
5993 [Steve Henson and Ben Laurie]
5995 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
5996 `openssl' and second, the shortcut symlinks for the `openssl <command>'
5997 are no longer created. This way we have a single and consistent command
5998 line interface `openssl <command>', similar to `cvs <command>'.
5999 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
6001 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
6002 BIT STRING wrapper always have zero unused bits.
6005 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
6008 *) Make the top-level INSTALL documentation easier to understand.
6011 *) Makefiles updated to exit if an error occurs in a sub-directory
6012 make (including if user presses ^C) [Paul Sutton]
6014 *) Make Montgomery context stuff explicit in RSA data structure.
6017 *) Fix build order of pem and err to allow for generated pem.h.
6020 *) Fix renumbering bug in X509_NAME_delete_entry().
6023 *) Enhanced the err-ins.pl script so it makes the error library number
6024 global and can add a library name. This is needed for external ASN1 and
6025 other error libraries.
6028 *) Fixed sk_insert which never worked properly.
6031 *) Fix ASN1 macros so they can handle indefinite length construted
6032 EXPLICIT tags. Some non standard certificates use these: they can now
6036 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
6037 into a single doc/ssleay.txt bundle. This way the information is still
6038 preserved but no longer messes up this directory. Now it's new room for
6039 the new set of documenation files.
6040 [Ralf S. Engelschall]
6042 *) SETs were incorrectly DER encoded. This was a major pain, because they
6043 shared code with SEQUENCEs, which aren't coded the same. This means that
6044 almost everything to do with SETs or SEQUENCEs has either changed name or
6045 number of arguments.
6046 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
6048 *) Fix test data to work with the above.
6051 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
6052 was already fixed by Eric for 0.9.1 it seems.
6053 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
6055 *) Autodetect FreeBSD3.
6058 *) Fix various bugs in Configure. This affects the following platforms:
6062 unixware-2.0-pentium
6066 *) Eliminate generated files from CVS. Reorder tests to regenerate files
6067 before they are needed.
6070 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
6074 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
6076 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
6077 changed SSLeay to OpenSSL in version strings.
6078 [Ralf S. Engelschall]
6080 *) Some fixups to the top-level documents.
6083 *) Fixed the nasty bug where rsaref.h was not found under compile-time
6084 because the symlink to include/ was missing.
6085 [Ralf S. Engelschall]
6087 *) Incorporated the popular no-RSA/DSA-only patches
6088 which allow to compile a RSA-free SSLeay.
6089 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
6091 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
6092 when "ssleay" is still not found.
6093 [Ralf S. Engelschall]
6095 *) Added more platforms to Configure: Cray T3E, HPUX 11,
6096 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
6098 *) Updated the README file.
6099 [Ralf S. Engelschall]
6101 *) Added various .cvsignore files in the CVS repository subdirs
6102 to make a "cvs update" really silent.
6103 [Ralf S. Engelschall]
6105 *) Recompiled the error-definition header files and added
6106 missing symbols to the Win32 linker tables.
6107 [Ralf S. Engelschall]
6109 *) Cleaned up the top-level documents;
6110 o new files: CHANGES and LICENSE
6111 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
6112 o merged COPYRIGHT into LICENSE
6113 o removed obsolete TODO file
6114 o renamed MICROSOFT to INSTALL.W32
6115 [Ralf S. Engelschall]
6117 *) Removed dummy files from the 0.9.1b source tree:
6118 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
6119 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
6120 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
6121 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
6122 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
6123 [Ralf S. Engelschall]
6125 *) Added various platform portability fixes.
6128 *) The Genesis of the OpenSSL rpject:
6129 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
6130 Young and Tim J. Hudson created while they were working for C2Net until
6132 [The OpenSSL Project]
6135 Changes between 0.9.0b and 0.9.1b [not released]
6137 *) Updated a few CA certificates under certs/
6140 *) Changed some BIGNUM api stuff.
6143 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
6144 DGUX x86, Linux Alpha, etc.
6147 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
6148 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
6152 *) Add -strparse option to asn1pars program which parses nested
6154 [Dr Stephen Henson <shenson@bigfoot.com>]
6156 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
6159 *) DSA fix for "ca" program.
6162 *) Added "-genkey" option to "dsaparam" program.
6165 *) Added RIPE MD160 (rmd160) message digest.
6168 *) Added -a (all) option to "ssleay version" command.
6171 *) Added PLATFORM define which is the id given to Configure.
6174 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
6177 *) Extended the ASN.1 parser routines.
6180 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
6183 *) Added a BN_CTX to the BN library.
6186 *) Fixed the weak key values in DES library
6189 *) Changed API in EVP library for cipher aliases.
6192 *) Added support for RC2/64bit cipher.
6195 *) Converted the lhash library to the crypto/mem.c functions.
6198 *) Added more recognized ASN.1 object ids.
6201 *) Added more RSA padding checks for SSL/TLS.
6204 *) Added BIO proxy/filter functionality.
6207 *) Added extra_certs to SSL_CTX which can be used
6208 send extra CA certificates to the client in the CA cert chain sending
6209 process. It can be configured with SSL_CTX_add_extra_chain_cert().
6212 *) Now Fortezza is denied in the authentication phase because
6213 this is key exchange mechanism is not supported by SSLeay at all.
6216 *) Additional PKCS1 checks.
6219 *) Support the string "TLSv1" for all TLS v1 ciphers.
6222 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
6223 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
6226 *) Fixed a few memory leaks.
6229 *) Fixed various code and comment typos.
6232 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
6233 bytes sent in the client random.
