5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first data
8 read consists of only the final block it would not decrypted because
9 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
10 A misplaced 'break' also meant the decrypted final block might not be
11 copied until the next read.
14 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
15 a few extra parameters to the DH structure: these will be useful if
16 for example we want the value of 'q' or implement X9.42 DH.
19 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
20 provides hooks that allow the default DSA functions or functions on a
21 "per key" basis to be replaced. This allows hardware acceleration and
22 hardware key storage to be handled without major modification to the
23 library. Also added low level modexp hooks and CRYPTO_EX structure and
27 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
28 as "read only": it can't be written to and the buffer it points to will
29 not be freed. Reading from a read only BIO is much more efficient than
30 a normal memory BIO. This was added because there are several times when
31 an area of memory needs to be read from a BIO. The previous method was
32 to create a memory BIO and write the data to it, this results in two
33 copies of the data and an O(n^2) reading algorithm. There is a new
34 function BIO_new_mem_buf() which creates a read only memory BIO from
35 an area of memory. Also modified the PKCS#7 routines to use read only
39 *) Bugfix: ssl23_get_client_hello did not work properly when called in
40 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
41 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
42 but a retry condition occured while trying to read the rest.
45 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
46 NID_pkcs7_encrypted by default: this was wrong since this should almost
47 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
48 the encrypted data type: this is a more sensible place to put it and it
49 allows the PKCS#12 code to be tidied up that duplicated this
53 *) Changed obj_dat.pl script so it takes its input and output files on
54 the command line. This should avoid shell escape redirection problems
58 *) Initial support for certificate extension requests, these are included
59 in things like Xenroll certificate requests. Included functions to allow
60 extensions to be obtained and added.
63 *) -crlf option to s_client and s_server for sending newlines as
64 CRLF (as required by many protocols).
67 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
69 *) Install libRSAglue.a when OpenSSL is built with RSAref.
72 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
73 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
75 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
79 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
80 DH parameters/keys (q is lost during that conversion, but the resulting
81 DH parameters contain its length).
83 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
84 much faster than DH_generate_parameters (which creates parameters
85 where p = 2*q + 1), and also the smaller q makes DH computations
86 much more efficient (160-bit exponentiation instead of 1024-bit
87 exponentiation); so this provides a convenient way to support DHE
88 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
89 utter importance to use
90 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
92 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
93 when such DH parameters are used, because otherwise small subgroup
94 attacks may become possible!
97 *) Avoid memory leak in i2d_DHparams.
100 *) Allow the -k option to be used more than once in the enc program:
101 this allows the same encrypted message to be read by multiple recipients.
104 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
105 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
106 it will always use the numerical form of the OID, even if it has a short
110 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
111 method only got called if p,q,dmp1,dmq1,iqmp components were present,
112 otherwise bn_mod_exp was called. In the case of hardware keys for example
113 no private key components need be present and it might store extra data
114 in the RSA structure, which cannot be accessed from bn_mod_exp. By setting
115 RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for private key
119 *) Added support for SPARC Linux.
122 *) pem_password_cb function type incompatibly changed from
123 typedef int pem_password_cb(char *buf, int size, int rwflag);
125 ....(char *buf, int size, int rwflag, void *userdata);
126 so that applications can pass data to their callbacks:
127 The PEM[_ASN1]_{read,write}... functions and macros now take an
128 additional void * argument, which is just handed through whenever
129 the password callback is called.
130 [Damien Miller <dmiller@ilogic.com.au>, with tiny changes by Bodo Moeller]
132 New function SSL_CTX_set_default_passwd_cb_userdata.
134 Compatibility note: As many C implementations push function arguments
135 onto the stack in reverse order, the new library version is likely to
136 interoperate with programs that have been compiled with the old
137 pem_password_cb definition (PEM_whatever takes some data that
138 happens to be on the stack as its last argument, and the callback
139 just ignores this garbage); but there is no guarantee whatsoever that
142 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
143 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
144 problems not only on Windows, but also on some Unix platforms.
145 To avoid problematic command lines, these definitions are now in an
146 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
147 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
150 *) MIPS III/IV assembler module is reimplemented.
153 *) More DES library cleanups: remove references to srand/rand and
154 delete an unused file.
157 *) Add support for the the free Netwide assembler (NASM) under Win32,
158 since not many people have MASM (ml) and it can be hard to obtain.
159 This is currently experimental but it seems to work OK and pass all
160 the tests. Check out INSTALL.W32 for info.
163 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
164 without temporary keys kept an extra copy of the server key,
165 and connections with temporary keys did not free everything in case
169 *) New function RSA_check_key and new openssl rsa option -check
170 for verifying the consistency of RSA keys.
171 [Ulf Moeller, Bodo Moeller]
173 *) Various changes to make Win32 compile work:
174 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
175 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
176 comparison" warnings.
177 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
180 *) Add a debugging option to PKCS#5 v2 key generation function: when
181 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
182 derived keys are printed to stderr.
185 *) Copy the flags in ASN1_STRING_dup().
186 [Roman E. Pavlov <pre@mo.msk.ru>]
188 *) The x509 application mishandled signing requests containing DSA
189 keys when the signing key was also DSA and the parameters didn't match.
191 It was supposed to omit the parameters when they matched the signing key:
192 the verifying software was then supposed to automatically use the CA's
193 parameters if they were absent from the end user certificate.
195 Omitting parameters is no longer recommended. The test was also
196 the wrong way round! This was probably due to unusual behaviour in
197 EVP_cmp_parameters() which returns 1 if the parameters match.
198 This meant that parameters were omitted when they *didn't* match and
199 the certificate was useless. Certificates signed with 'ca' didn't have
201 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
203 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
204 The interface is as follows:
206 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
207 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
208 "off" is now the default.
209 The library internally uses
210 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
211 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
212 to disable memory-checking temporarily.
214 Some inconsistent states that previously were possible (and were
215 even the default) are now avoided.
217 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
218 with each memory chunk allocated; this is occasionally more helpful
219 than just having a counter.
221 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
223 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
227 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
228 which largely parallels "options", but is for changing API behaviour,
229 whereas "options" are about protocol behaviour.
230 Initial "mode" flags are:
232 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
233 a single record has been written.
234 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
235 retries use the same buffer location.
236 (But all of the contents must be
240 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
243 *) Fix problems with no-hmac etc.
244 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
246 *) New functions RSA_get_default_method(), RSA_set_method() and
247 RSA_get_method(). These allows replacement of RSA_METHODs without having
248 to mess around with the internals of an RSA structure.
251 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
252 Also really enable memory leak checks in openssl.c and in some
254 [Chad C. Mulligan, Bodo Moeller]
256 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
257 up the length of negative integers. This has now been simplified to just
258 store the length when it is first determined and use it later, rather
259 than trying to keep track of where data is copied and updating it to
261 [Steve Henson, reported by Brien Wheeler
262 <bwheeler@authentica-security.com>]
264 *) Add a new function PKCS7_signatureVerify. This allows the verification
265 of a PKCS#7 signature but with the signing certificate passed to the
266 function itself. This contrasts with PKCS7_dataVerify which assumes the
267 certificate is present in the PKCS#7 structure. This isn't always the
268 case: certificates can be omitted from a PKCS#7 structure and be
269 distributed by "out of band" means (such as a certificate database).
272 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
273 function prototypes in pem.h, also change util/mkdef.pl to add the
274 necessary function names.
277 *) mk1mf.pl (used by Windows builds) did not properly read the
278 options set by Configure in the top level Makefile, and Configure
279 was not even able to write more than one option correctly.
280 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
283 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
284 file to be loaded from a BIO or FILE pointer. The BIO version will
285 for example allow memory BIOs to contain config info.
288 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
289 Whoever hopes to achieve shared-library compatibility across versions
290 must use this, not the compile-time macro.
291 (Exercise 0.9.4: Which is the minimum library version required by
293 Note: All this applies only to multi-threaded programs, others don't
297 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
298 through a BIO pair triggered the default case, i.e.
299 SSLerr(...,SSL_R_UNKNOWN_STATE).
302 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
303 can use the SSL library even if none of the specific BIOs is
307 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
308 for the encoded length.
309 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
311 *) Add initial documentation of the X509V3 functions.
314 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
315 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
316 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
317 secure PKCS#8 private key format with a high iteration count.
320 *) Fix determination of Perl interpreter: A perl or perl5
321 _directory_ in $PATH was also accepted as the interpreter.
322 [Ralf S. Engelschall]
324 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
325 wrong with it but it was very old and did things like calling
326 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
330 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
331 to use the new extension code.
334 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
335 with macros. This should make it easier to change their form, add extra
336 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
340 *) Add to configuration table a new entry that can specify an alternative
341 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
342 according to Mark Crispin <MRC@Panda.COM>.
346 *) DES CBC did not update the IV. Weird.
349 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
350 Changing the behaviour of the former might break existing programs --
351 where IV updating is needed, des_ncbc_encrypt can be used.
354 *) When bntest is run from "make test" it drives bc to check its
355 calculations, as well as internally checking them. If an internal check
356 fails, it needs to cause bc to give a non-zero result or make test carries
357 on without noticing the failure. Fixed.
360 *) DES library cleanups.
363 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
364 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
365 ciphers. NOTE: although the key derivation function has been verified
366 against some published test vectors it has not been extensively tested
367 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
371 *) Instead of "mkdir -p", which is not fully portable, use new
372 Perl script "util/mkdir-p.pl".
375 *) Rewrite the way password based encryption (PBE) is handled. It used to
376 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
377 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
378 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
379 the 'parameter' field of the AlgorithmIdentifier is passed to the
380 underlying key generation function so it must do its own ASN1 parsing.
381 This has also changed the EVP_PBE_CipherInit() function which now has a
382 'parameter' argument instead of literal salt and iteration count values
383 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
386 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
387 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
388 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
389 KEY" because this clashed with PKCS#8 unencrypted string. Since this
390 value was just used as a "magic string" and not used directly its
391 value doesn't matter.
394 *) Introduce some semblance of const correctness to BN. Shame C doesn't
398 *) "linux-sparc64" configuration (ultrapenguin).
399 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
400 "linux-sparc" configuration.
401 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
403 *) config now generates no-xxx options for missing ciphers.
406 *) Support the EBCDIC character set (work in progress).
407 File ebcdic.c not yet included because it has a different license.
408 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
410 *) Support BS2000/OSD-POSIX.
411 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
413 *) Make callbacks for key generation use void * instead of char *.
416 *) Make S/MIME samples compile (not yet tested).
419 *) Additional typesafe stacks.
422 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
426 Changes between 0.9.3 and 0.9.3a [29 May 1999]
428 *) New configuration variant "sco5-gcc".
430 *) Updated some demos.
431 [Sean O Riordain, Wade Scholine]
433 *) Add missing BIO_free at exit of pkcs12 application.
436 *) Fix memory leak in conf.c.
439 *) Updates for Win32 to assembler version of MD5.
442 *) Set #! path to perl in apps/der_chop to where we found it
443 instead of using a fixed path.
446 *) SHA library changes for irix64-mips4-cc.
449 *) Improvements for VMS support.
453 Changes between 0.9.2b and 0.9.3 [24 May 1999]
455 *) Bignum library bug fix. IRIX 6 passes "make test" now!
456 This also avoids the problems with SC4.2 and unpatched SC5.
457 [Andy Polyakov <appro@fy.chalmers.se>]
459 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
460 These are required because of the typesafe stack would otherwise break
461 existing code. If old code used a structure member which used to be STACK
462 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
463 sk_num or sk_value it would produce an error because the num, data members
464 are not present in STACK_OF. Now it just produces a warning. sk_set
465 replaces the old method of assigning a value to sk_value
466 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
467 that does this will no longer work (and should use sk_set instead) but
468 this could be regarded as a "questionable" behaviour anyway.
471 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
472 correctly handle encrypted S/MIME data.
475 *) Change type of various DES function arguments from des_cblock
476 (which means, in function argument declarations, pointer to char)
477 to des_cblock * (meaning pointer to array with 8 char elements),
478 which allows the compiler to do more typechecking; it was like
479 that back in SSLeay, but with lots of ugly casts.
481 Introduce new type const_des_cblock.
484 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
485 problems: find RecipientInfo structure that matches recipient certificate
486 and initialise the ASN1 structures properly based on passed cipher.
489 *) Belatedly make the BN tests actually check the results.
492 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
493 to and from BNs: it was completely broken. New compilation option
494 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
495 key elements as negative integers.
498 *) Reorganize and speed up MD5.
499 [Andy Polyakov <appro@fy.chalmers.se>]
502 [Richard Levitte <richard@levitte.org>]
504 *) New option -out to asn1parse to allow the parsed structure to be
505 output to a file. This is most useful when combined with the -strparse
506 option to examine the output of things like OCTET STRINGS.
509 *) Make SSL library a little more fool-proof by not requiring any longer
510 that SSL_set_{accept,connect}_state be called before
511 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
512 in many applications because usually everything *appeared* to work as
513 intended anyway -- now it really works as intended).
516 *) Move openssl.cnf out of lib/.
519 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
520 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
521 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
522 [Ralf S. Engelschall]
524 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
525 handle PKCS#7 enveloped data properly.
526 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
528 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
529 copying pointers. The cert_st handling is changed by this in
530 various ways (and thus what used to be known as ctx->default_cert
531 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
532 any longer when s->cert does not give us what we need).
533 ssl_cert_instantiate becomes obsolete by this change.
534 As soon as we've got the new code right (possibly it already is?),
535 we have solved a couple of bugs of the earlier code where s->cert
536 was used as if it could not have been shared with other SSL structures.
538 Note that using the SSL API in certain dirty ways now will result
539 in different behaviour than observed with earlier library versions:
540 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
541 does not influence s as it used to.
543 In order to clean up things more thoroughly, inside SSL_SESSION
544 we don't use CERT any longer, but a new structure SESS_CERT
545 that holds per-session data (if available); currently, this is
546 the peer's certificate chain and, for clients, the server's certificate
547 and temporary key. CERT holds only those values that can have
548 meaningful defaults in an SSL_CTX.
551 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
552 from the internal representation. Various PKCS#7 fixes: remove some
553 evil casts and set the enc_dig_alg field properly based on the signing
557 *) Allow PKCS#12 password to be set from the command line or the
558 environment. Let 'ca' get its config file name from the environment
559 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
563 *) Allow certificate policies extension to use an IA5STRING for the
564 organization field. This is contrary to the PKIX definition but
565 VeriSign uses it and IE5 only recognises this form. Document 'x509'
569 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
570 without disallowing inline assembler and the like for non-pedantic builds.
573 *) Support Borland C++ builder.
574 [Janez Jere <jj@void.si>, modified by Ulf Möller]
579 *) SHA-1 cleanups and performance enhancements.
580 [Andy Polyakov <appro@fy.chalmers.se>]
582 *) Sparc v8plus assembler for the bignum library.
583 [Andy Polyakov <appro@fy.chalmers.se>]
585 *) Accept any -xxx and +xxx compiler options in Configure.
588 *) Update HPUX configuration.
591 *) Add missing sk_<type>_unshift() function to safestack.h
592 [Ralf S. Engelschall]
594 *) New function SSL_CTX_use_certificate_chain_file that sets the
595 "extra_cert"s in addition to the certificate. (This makes sense
596 only for "PEM" format files, as chains as a whole are not
600 *) Support verify_depth from the SSL API.
601 x509_vfy.c had what can be considered an off-by-one-error:
602 Its depth (which was not part of the external interface)
603 was actually counting the number of certificates in a chain;
604 now it really counts the depth.
607 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
608 instead of X509err, which often resulted in confusing error
609 messages since the error codes are not globally unique
610 (e.g. an alleged error in ssl3_accept when a certificate
611 didn't match the private key).
613 *) New function SSL_CTX_set_session_id_context that allows to set a default
614 value (so that you don't need SSL_set_session_id_context for each
615 connection using the SSL_CTX).
618 *) OAEP decoding bug fix.
621 *) Support INSTALL_PREFIX for package builders, as proposed by
625 *) New Configure options "threads" and "no-threads". For systems
626 where the proper compiler options are known (currently Solaris
627 and Linux), "threads" is the default.
630 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
633 *) Install various scripts to $(OPENSSLDIR)/misc, not to
634 $(INSTALLTOP)/bin -- they shouldn't clutter directories
635 such as /usr/local/bin.
638 *) "make linux-shared" to build shared libraries.
639 [Niels Poppe <niels@netbox.org>]
641 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
644 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
645 extension adding in x509 utility.
648 *) Remove NOPROTO sections and error code comments.
651 *) Partial rewrite of the DEF file generator to now parse the ANSI
655 *) New Configure options --prefix=DIR and --openssldir=DIR.
658 *) Complete rewrite of the error code script(s). It is all now handled
659 by one script at the top level which handles error code gathering,
660 header rewriting and C source file generation. It should be much better
661 than the old method: it now uses a modified version of Ulf's parser to
662 read the ANSI prototypes in all header files (thus the old K&R definitions
663 aren't needed for error creation any more) and do a better job of
664 translating function codes into names. The old 'ASN1 error code imbedded
665 in a comment' is no longer necessary and it doesn't use .err files which
666 have now been deleted. Also the error code call doesn't have to appear all
667 on one line (which resulted in some large lines...).
670 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
673 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
674 0 (which usually indicates a closed connection), but continue reading.
677 *) Fix some race conditions.
680 *) Add support for CRL distribution points extension. Add Certificate
681 Policies and CRL distribution points documentation.
684 *) Move the autogenerated header file parts to crypto/opensslconf.h.
687 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
688 8 of keying material. Merlin has also confirmed interop with this fix
689 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
690 [Merlin Hughes <merlin@baltimore.ie>]
692 *) Fix lots of warnings.
693 [Richard Levitte <levitte@stacken.kth.se>]
695 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
696 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
697 [Richard Levitte <levitte@stacken.kth.se>]
699 *) Fix problems with sizeof(long) == 8.
700 [Andy Polyakov <appro@fy.chalmers.se>]
702 *) Change functions to ANSI C.
705 *) Fix typos in error codes.
706 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
708 *) Remove defunct assembler files from Configure.
711 *) SPARC v8 assembler BIGNUM implementation.
712 [Andy Polyakov <appro@fy.chalmers.se>]
714 *) Support for Certificate Policies extension: both print and set.
715 Various additions to support the r2i method this uses.
718 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
719 return a const string when you are expecting an allocated buffer.
722 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
723 types DirectoryString and DisplayText.
726 *) Add code to allow r2i extensions to access the configuration database,
727 add an LHASH database driver and add several ctx helper functions.
730 *) Fix an evil bug in bn_expand2() which caused various BN functions to
731 fail when they extended the size of a BIGNUM.
734 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
735 support typesafe stack.
738 *) Fix typo in SSL_[gs]et_options().
739 [Nils Frostberg <nils@medcom.se>]
741 *) Delete various functions and files that belonged to the (now obsolete)
742 old X509V3 handling code.
745 *) New Configure option "rsaref".
748 *) Don't auto-generate pem.h.
751 *) Introduce type-safe ASN.1 SETs.
754 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
755 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
757 *) Introduce type-safe STACKs. This will almost certainly break lots of code
758 that links with OpenSSL (well at least cause lots of warnings), but fear
759 not: the conversion is trivial, and it eliminates loads of evil casts. A
760 few STACKed things have been converted already. Feel free to convert more.
761 In the fullness of time, I'll do away with the STACK type altogether.
764 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
765 specified in <certfile> by updating the entry in the index.txt file.
766 This way one no longer has to edit the index.txt file manually for
767 revoking a certificate. The -revoke option does the gory details now.
768 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
770 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
771 `-text' option at all and this way the `-noout -text' combination was
772 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
773 [Ralf S. Engelschall]
775 *) Make sure a corresponding plain text error message exists for the
776 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
777 verify callback function determined that a certificate was revoked.
778 [Ralf S. Engelschall]
780 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
781 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
782 all available cipers including rc5, which was forgotten until now.
783 In order to let the testing shell script know which algorithms
784 are available, a new (up to now undocumented) command
785 "openssl list-cipher-commands" is used.
788 *) Bugfix: s_client occasionally would sleep in select() when
789 it should have checked SSL_pending() first.
792 *) New functions DSA_do_sign and DSA_do_verify to provide access to
793 the raw DSA values prior to ASN.1 encoding.
796 *) Tweaks to Configure
797 [Niels Poppe <niels@netbox.org>]
799 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
803 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
806 *) New config option to avoid instructions that are illegal on the 80386.
807 The default code is faster, but requires at least a 486.
810 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
811 SSL2_SERVER_VERSION (not used at all) macros, which are now the
812 same as SSL2_VERSION anyway.
815 *) New "-showcerts" option for s_client.
818 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
819 application. Various cleanups and fixes.
822 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
823 modify error routines to work internally. Add error codes and PBE init
824 to library startup routines.
827 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
828 packing functions to asn1 and evp. Changed function names and error
832 *) PKCS12 integration: and so it begins... First of several patches to
833 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
837 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
838 and display support for Thawte strong extranet extension.
841 *) Add LinuxPPC support.
842 [Jeff Dubrule <igor@pobox.org>]
844 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
845 bn_div_words in alpha.s.
846 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
848 *) Make sure the RSA OAEP test is skipped under -DRSAref because
849 OAEP isn't supported when OpenSSL is built with RSAref.
850 [Ulf Moeller <ulf@fitug.de>]
852 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
853 so they no longer are missing under -DNOPROTO.
854 [Soren S. Jorvang <soren@t.dk>]
857 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
859 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
860 doesn't work when the session is reused. Coming soon!
863 *) Fix a security hole, that allows sessions to be reused in the wrong
864 context thus bypassing client cert protection! All software that uses
865 client certs and session caches in multiple contexts NEEDS PATCHING to
866 allow session reuse! A fuller solution is in the works.
867 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
869 *) Some more source tree cleanups (removed obsolete files
870 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
871 permission on "config" script to be executable) and a fix for the INSTALL
873 [Ulf Moeller <ulf@fitug.de>]
875 *) Remove some legacy and erroneous uses of malloc, free instead of
877 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
879 *) Make rsa_oaep_test return non-zero on error.
880 [Ulf Moeller <ulf@fitug.de>]
882 *) Add support for native Solaris shared libraries. Configure
883 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
884 if someone would make that last step automatic.
885 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
887 *) ctx_size was not built with the right compiler during "make links". Fixed.
890 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
891 except NULL ciphers". This means the default cipher list will no longer
892 enable NULL ciphers. They need to be specifically enabled e.g. with
893 the string "DEFAULT:eNULL".
896 *) Fix to RSA private encryption routines: if p < q then it would
897 occasionally produce an invalid result. This will only happen with
898 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
901 *) Be less restrictive and allow also `perl util/perlpath.pl
902 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
903 because this way one can also use an interpreter named `perl5' (which is
904 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
905 installed as `perl').
906 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
908 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
909 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
911 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
912 advapi32.lib to Win32 build and change the pem test comparision
913 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
914 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
915 and crypto/des/ede_cbcm_enc.c.
918 *) DES quad checksum was broken on big-endian architectures. Fixed.
921 *) Comment out two functions in bio.h that aren't implemented. Fix up the
922 Win32 test batch file so it (might) work again. The Win32 test batch file
923 is horrible: I feel ill....
926 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
927 in e_os.h. Audit of header files to check ANSI and non ANSI
928 sections: 10 functions were absent from non ANSI section and not exported
929 from Windows DLLs. Fixed up libeay.num for new functions.
932 *) Make `openssl version' output lines consistent.
933 [Ralf S. Engelschall]
935 *) Fix Win32 symbol export lists for BIO functions: Added
936 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
937 to ms/libeay{16,32}.def.
938 [Ralf S. Engelschall]
940 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
941 fine under Unix and passes some trivial tests I've now added. But the
942 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
943 added to make sure no one expects that this stuff really works in the
944 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
945 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
947 [Ralf S. Engelschall]
949 *) Fix the generation of two part addresses in perl.
950 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
952 *) Add config entry for Linux on MIPS.
953 [John Tobey <jtobey@channel1.com>]
955 *) Make links whenever Configure is run, unless we are on Windoze.
958 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
959 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
963 *) Add a useful kludge to allow package maintainers to specify compiler and
964 other platforms details on the command line without having to patch the
965 Configure script everytime: One now can use ``perl Configure
966 <id>:<details>'', i.e. platform ids are allowed to have details appended
967 to them (seperated by colons). This is treated as there would be a static
968 pre-configured entry in Configure's %table under key <id> with value
969 <details> and ``perl Configure <id>'' is called. So, when you want to
970 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
971 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
972 now, which overrides the FreeBSD-elf entry on-the-fly.
973 [Ralf S. Engelschall]
975 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
978 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
979 on the `perl Configure ...' command line. This way one can compile
980 OpenSSL libraries with Position Independent Code (PIC) which is needed
981 for linking it into DSOs.
982 [Ralf S. Engelschall]
984 *) Remarkably, export ciphers were totally broken and no-one had noticed!
988 *) Cleaned up the LICENSE document: The official contact for any license
989 questions now is the OpenSSL core team under openssl-core@openssl.org.
990 And add a paragraph about the dual-license situation to make sure people
991 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
992 to the OpenSSL toolkit.
993 [Ralf S. Engelschall]
995 *) General source tree makefile cleanups: Made `making xxx in yyy...'
996 display consistent in the source tree and replaced `/bin/rm' by `rm'.
997 Additonally cleaned up the `make links' target: Remove unnecessary
998 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
999 to speed processing and no longer clutter the display with confusing
1000 stuff. Instead only the actually done links are displayed.
1001 [Ralf S. Engelschall]
1003 *) Permit null encryption ciphersuites, used for authentication only. It used
1004 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
1005 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
1009 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
1010 signed attributes when verifying signatures (this would break them),
1011 the detached data encoding was wrong and public keys obtained using
1012 X509_get_pubkey() weren't freed.
1015 *) Add text documentation for the BUFFER functions. Also added a work around
1016 to a Win95 console bug. This was triggered by the password read stuff: the
1017 last character typed gets carried over to the next fread(). If you were
1018 generating a new cert request using 'req' for example then the last
1019 character of the passphrase would be CR which would then enter the first
1023 *) Added the new `Includes OpenSSL Cryptography Software' button as
1024 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
1025 button and can be used by applications based on OpenSSL to show the
1026 relationship to the OpenSSL project.
1027 [Ralf S. Engelschall]
1029 *) Remove confusing variables in function signatures in files
1030 ssl/ssl_lib.c and ssl/ssl.h.
1031 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1033 *) Don't install bss_file.c under PREFIX/include/
1034 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1036 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
1037 functions that return function pointers and has support for NT specific
1038 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1039 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1040 unsigned to signed types: this was killing the Win32 compile.
1043 *) Add new certificate file to stack functions,
1044 SSL_add_dir_cert_subjects_to_stack() and
1045 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1046 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1047 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1048 This means that Apache-SSL and similar packages don't have to mess around
1049 to add as many CAs as they want to the preferred list.
1052 *) Experiment with doxygen documentation. Currently only partially applied to
1054 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1055 openssl.doxy as the configuration file.
1058 *) Get rid of remaining C++-style comments which strict C compilers hate.
1059 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1061 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1062 compiled in by default: it has problems with large keys.
1065 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1066 DH private keys and/or callback functions which directly correspond to
1067 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1068 is needed for applications which have to configure certificates on a
1069 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1071 For the RSA certificate situation is makes no difference, but
1072 for the DSA certificate situation this fixes the "no shared cipher"
1073 problem where the OpenSSL cipher selection procedure failed because the
1074 temporary keys were not overtaken from the context and the API provided
1075 no way to reconfigure them.
1076 The new functions now let applications reconfigure the stuff and they
1077 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1078 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1079 non-public-API function ssl_cert_instantiate() is used as a helper
1080 function and also to reduce code redundancy inside ssl_rsa.c.
1081 [Ralf S. Engelschall]
1083 *) Move s_server -dcert and -dkey options out of the undocumented feature
1084 area because they are useful for the DSA situation and should be
1085 recognized by the users.
1086 [Ralf S. Engelschall]
1088 *) Fix the cipher decision scheme for export ciphers: the export bits are
1089 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1090 SSL_EXP_MASK. So, the original variable has to be used instead of the
1091 already masked variable.
1092 [Richard Levitte <levitte@stacken.kth.se>]
1094 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1095 [Richard Levitte <levitte@stacken.kth.se>]
1097 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1098 from `int' to `unsigned int' because it's a length and initialized by
1099 EVP_DigestFinal() which expects an `unsigned int *'.
1100 [Richard Levitte <levitte@stacken.kth.se>]
1102 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1103 script. Instead use the usual Shell->Perl transition trick.
1104 [Ralf S. Engelschall]
1106 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1107 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1108 -noout -modulus' as it's already the case for `openssl rsa -noout
1109 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1110 currently the public key is printed (a decision which was already done by
1111 `openssl dsa -modulus' in the past) which serves a similar purpose.
1112 Additionally the NO_RSA no longer completely removes the whole -modulus
1113 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1115 [Ralf S. Engelschall]
1117 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1118 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1119 [Arne Ansper <arne@ats.cyber.ee>]
1121 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1122 to be added. Now both 'req' and 'ca' can use new objects defined in the
1126 *) Add cool BIO that does syslog (or event log on NT).
1127 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1129 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1130 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1131 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1132 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1135 *) Add preliminary config info for new extension code.
1138 *) Make RSA_NO_PADDING really use no padding.
1139 [Ulf Moeller <ulf@fitug.de>]
1141 *) Generate errors when private/public key check is done.
1144 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1145 for some CRL extensions and new objects added.
1148 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1149 key usage extension and fuller support for authority key id.
1152 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1153 padding method for RSA, which is recommended for new applications in PKCS
1154 #1 v2.0 (RFC 2437, October 1998).
1155 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1156 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1157 against Bleichbacher's attack on RSA.
1158 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1161 *) Updates to the new SSL compression code
1162 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1164 *) Fix so that the version number in the master secret, when passed
1165 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1166 (because the server will not accept higher), that the version number
1167 is 0x03,0x01, not 0x03,0x00
1168 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1170 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1171 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1172 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1175 *) Support for RAW extensions where an arbitrary extension can be
1176 created by including its DER encoding. See apps/openssl.cnf for
1180 *) Make sure latest Perl versions don't interpret some generated C array
1181 code as Perl array code in the crypto/err/err_genc.pl script.
1182 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1184 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1185 not many people have the assembler. Various Win32 compilation fixes and
1186 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1190 *) Modify configure script 'Configure' to automatically create crypto/date.h
1191 file under Win32 and also build pem.h from pem.org. New script
1192 util/mkfiles.pl to create the MINFO file on environments that can't do a
1193 'make files': perl util/mkfiles.pl >MINFO should work.
1196 *) Major rework of DES function declarations, in the pursuit of correctness
1197 and purity. As a result, many evil casts evaporated, and some weirdness,
1198 too. You may find this causes warnings in your code. Zapping your evil
1199 casts will probably fix them. Mostly.
1202 *) Fix for a typo in asn1.h. Bug fix to object creation script
1203 obj_dat.pl. It considered a zero in an object definition to mean
1204 "end of object": none of the objects in objects.h have any zeros
1205 so it wasn't spotted.
1206 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1208 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1209 Masking (CBCM). In the absence of test vectors, the best I have been able
1210 to do is check that the decrypt undoes the encrypt, so far. Send me test
1211 vectors if you have them.
1214 *) Correct calculation of key length for export ciphers (too much space was
1215 allocated for null ciphers). This has not been tested!
1218 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1219 message is now correct (it understands "crypto" and "ssl" on its
1220 command line). There is also now an "update" option. This will update
1221 the util/ssleay.num and util/libeay.num files with any new functions.
1223 perl util/mkdef.pl crypto ssl update
1224 it will update them.
1227 *) Overhauled the Perl interface (perl/*):
1228 - ported BN stuff to OpenSSL's different BN library
1229 - made the perl/ source tree CVS-aware
1230 - renamed the package from SSLeay to OpenSSL (the files still contain
1231 their history because I've copied them in the repository)
1232 - removed obsolete files (the test scripts will be replaced
1233 by better Test::Harness variants in the future)
1234 [Ralf S. Engelschall]
1236 *) First cut for a very conservative source tree cleanup:
1237 1. merge various obsolete readme texts into doc/ssleay.txt
1238 where we collect the old documents and readme texts.
1239 2. remove the first part of files where I'm already sure that we no
1240 longer need them because of three reasons: either they are just temporary
1241 files which were left by Eric or they are preserved original files where
1242 I've verified that the diff is also available in the CVS via "cvs diff
1243 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1244 the crypto/md/ stuff).
1245 [Ralf S. Engelschall]
1247 *) More extension code. Incomplete support for subject and issuer alt
1248 name, issuer and authority key id. Change the i2v function parameters
1249 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1250 what that's for :-) Fix to ASN1 macro which messed up
1251 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1254 *) Preliminary support for ENUMERATED type. This is largely copied from the
1258 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1259 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1261 *) Make sure `make rehash' target really finds the `openssl' program.
1262 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1264 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1265 like to hear about it if this slows down other processors.
1268 *) Add CygWin32 platform information to Configure script.
1269 [Alan Batie <batie@aahz.jf.intel.com>]
1271 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1272 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1274 *) New program nseq to manipulate netscape certificate sequences
1277 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1281 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1282 but the BN code had some problems that would cause failures when
1283 doing certificate verification and some other functions.
1284 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1286 *) Add ASN1 and PEM code to support netscape certificate sequences.
1289 *) Add ASN1 and PEM code to support netscape certificate sequences.
1292 *) Add several PKIX and private extended key usage OIDs.
1295 *) Modify the 'ca' program to handle the new extension code. Modify
1296 openssl.cnf for new extension format, add comments.
1299 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1300 and add a sample to openssl.cnf so req -x509 now adds appropriate
1304 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1305 error code, add initial support to X509_print() and x509 application.
1308 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1309 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1310 stuff is currently isolated and isn't even compiled yet.
1313 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1314 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1315 Removed the versions check from X509 routines when loading extensions:
1316 this allows certain broken certificates that don't set the version
1317 properly to be processed.
1320 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1321 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1322 can still be regenerated with "make depend".
1325 *) Spelling mistake in C version of CAST-128.
1326 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1328 *) Changes to the error generation code. The perl script err-code.pl
1329 now reads in the old error codes and retains the old numbers, only
1330 adding new ones if necessary. It also only changes the .err files if new
1331 codes are added. The makefiles have been modified to only insert errors
1332 when needed (to avoid needlessly modifying header files). This is done
1333 by only inserting errors if the .err file is newer than the auto generated
1334 C file. To rebuild all the error codes from scratch (the old behaviour)
1335 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1336 or delete all the .err files.
1339 *) CAST-128 was incorrectly implemented for short keys. The C version has
1340 been fixed, but is untested. The assembler versions are also fixed, but
1341 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1342 to regenerate it if needed.
1343 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1344 Hagino <itojun@kame.net>]
1346 *) File was opened incorrectly in randfile.c.
1347 [Ulf Möller <ulf@fitug.de>]
1349 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1350 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1351 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1352 al: it's just almost always a UTCTime. Note this patch adds new error
1353 codes so do a "make errors" if there are problems.
1356 *) Correct Linux 1 recognition in config.
1357 [Ulf Möller <ulf@fitug.de>]
1359 *) Remove pointless MD5 hash when using DSA keys in ca.
1360 [Anonymous <nobody@replay.com>]
1362 *) Generate an error if given an empty string as a cert directory. Also
1363 generate an error if handed NULL (previously returned 0 to indicate an
1364 error, but didn't set one).
1365 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1367 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1370 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1371 parameters. This was causing a warning which killed off the Win32 compile.
1374 *) Remove C++ style comments from crypto/bn/bn_local.h.
1375 [Neil Costigan <neil.costigan@celocom.com>]
1377 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1378 based on a text string, looking up short and long names and finally
1379 "dot" format. The "dot" format stuff didn't work. Added new function
1380 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1381 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1382 OID is not part of the table.
1385 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1386 X509_LOOKUP_by_alias().
1389 *) Sort openssl functions by name.
1392 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1393 encryption from sample DSA keys (in case anyone is interested the password
1397 *) Make _all_ *_free functions accept a NULL pointer.
1398 [Frans Heymans <fheymans@isaserver.be>]
1400 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1402 [Anonymous <nobody@replay.com>]
1404 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1405 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1407 *) Don't blow it for numeric -newkey arguments to apps/req.
1408 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1410 *) Temp key "for export" tests were wrong in s3_srvr.c.
1411 [Anonymous <nobody@replay.com>]
1413 *) Add prototype for temp key callback functions
1414 SSL_CTX_set_tmp_{rsa,dh}_callback().
1417 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1418 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1421 *) X509_name_add_entry() freed the wrong thing after an error.
1422 [Arne Ansper <arne@ats.cyber.ee>]
1424 *) rsa_eay.c would attempt to free a NULL context.
1425 [Arne Ansper <arne@ats.cyber.ee>]
1427 *) BIO_s_socket() had a broken should_retry() on Windoze.
1428 [Arne Ansper <arne@ats.cyber.ee>]
1430 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1431 [Arne Ansper <arne@ats.cyber.ee>]
1433 *) Make sure the already existing X509_STORE->depth variable is initialized
1434 in X509_STORE_new(), but document the fact that this variable is still
1435 unused in the certificate verification process.
1436 [Ralf S. Engelschall]
1438 *) Fix the various library and apps files to free up pkeys obtained from
1439 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1442 *) Fix reference counting in X509_PUBKEY_get(). This makes
1443 demos/maurice/example2.c work, amongst others, probably.
1444 [Steve Henson and Ben Laurie]
1446 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1447 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1448 are no longer created. This way we have a single and consistent command
1449 line interface `openssl <command>', similar to `cvs <command>'.
1450 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1452 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1453 BIT STRING wrapper always have zero unused bits.
1456 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1459 *) Make the top-level INSTALL documentation easier to understand.
1462 *) Makefiles updated to exit if an error occurs in a sub-directory
1463 make (including if user presses ^C) [Paul Sutton]
1465 *) Make Montgomery context stuff explicit in RSA data structure.
1468 *) Fix build order of pem and err to allow for generated pem.h.
1471 *) Fix renumbering bug in X509_NAME_delete_entry().
1474 *) Enhanced the err-ins.pl script so it makes the error library number
1475 global and can add a library name. This is needed for external ASN1 and
1476 other error libraries.
1479 *) Fixed sk_insert which never worked properly.
1482 *) Fix ASN1 macros so they can handle indefinite length construted
1483 EXPLICIT tags. Some non standard certificates use these: they can now
1487 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1488 into a single doc/ssleay.txt bundle. This way the information is still
1489 preserved but no longer messes up this directory. Now it's new room for
1490 the new set of documenation files.
1491 [Ralf S. Engelschall]
1493 *) SETs were incorrectly DER encoded. This was a major pain, because they
1494 shared code with SEQUENCEs, which aren't coded the same. This means that
1495 almost everything to do with SETs or SEQUENCEs has either changed name or
1496 number of arguments.
1497 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1499 *) Fix test data to work with the above.
1502 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1503 was already fixed by Eric for 0.9.1 it seems.
1504 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1506 *) Autodetect FreeBSD3.
1509 *) Fix various bugs in Configure. This affects the following platforms:
1513 unixware-2.0-pentium
1517 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1518 before they are needed.
1521 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1525 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1527 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1528 changed SSLeay to OpenSSL in version strings.
1529 [Ralf S. Engelschall]
1531 *) Some fixups to the top-level documents.
1534 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1535 because the symlink to include/ was missing.
1536 [Ralf S. Engelschall]
1538 *) Incorporated the popular no-RSA/DSA-only patches
1539 which allow to compile a RSA-free SSLeay.
1540 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1542 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1543 when "ssleay" is still not found.
1544 [Ralf S. Engelschall]
1546 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1547 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1549 *) Updated the README file.
1550 [Ralf S. Engelschall]
1552 *) Added various .cvsignore files in the CVS repository subdirs
1553 to make a "cvs update" really silent.
1554 [Ralf S. Engelschall]
1556 *) Recompiled the error-definition header files and added
1557 missing symbols to the Win32 linker tables.
1558 [Ralf S. Engelschall]
1560 *) Cleaned up the top-level documents;
1561 o new files: CHANGES and LICENSE
1562 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1563 o merged COPYRIGHT into LICENSE
1564 o removed obsolete TODO file
1565 o renamed MICROSOFT to INSTALL.W32
1566 [Ralf S. Engelschall]
1568 *) Removed dummy files from the 0.9.1b source tree:
1569 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1570 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1573 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1574 [Ralf S. Engelschall]
1576 *) Added various platform portability fixes.
1579 *) The Genesis of the OpenSSL rpject:
1580 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1581 Young and Tim J. Hudson created while they were working for C2Net until
1583 [The OpenSSL Project]
1586 Changes between 0.9.0b and 0.9.1b [not released]
1588 *) Updated a few CA certificates under certs/
1591 *) Changed some BIGNUM api stuff.
1594 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1595 DGUX x86, Linux Alpha, etc.
1598 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1599 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1603 *) Add -strparse option to asn1pars program which parses nested
1605 [Dr Stephen Henson <shenson@bigfoot.com>]
1607 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1610 *) DSA fix for "ca" program.
1613 *) Added "-genkey" option to "dsaparam" program.
1616 *) Added RIPE MD160 (rmd160) message digest.
1619 *) Added -a (all) option to "ssleay version" command.
1622 *) Added PLATFORM define which is the id given to Configure.
1625 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1628 *) Extended the ASN.1 parser routines.
1631 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1634 *) Added a BN_CTX to the BN library.
1637 *) Fixed the weak key values in DES library
1640 *) Changed API in EVP library for cipher aliases.
1643 *) Added support for RC2/64bit cipher.
1646 *) Converted the lhash library to the crypto/mem.c functions.
1649 *) Added more recognized ASN.1 object ids.
1652 *) Added more RSA padding checks for SSL/TLS.
1655 *) Added BIO proxy/filter functionality.
1658 *) Added extra_certs to SSL_CTX which can be used
1659 send extra CA certificates to the client in the CA cert chain sending
1660 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1663 *) Now Fortezza is denied in the authentication phase because
1664 this is key exchange mechanism is not supported by SSLeay at all.
1667 *) Additional PKCS1 checks.
1670 *) Support the string "TLSv1" for all TLS v1 ciphers.
1673 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1674 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1677 *) Fixed a few memory leaks.
1680 *) Fixed various code and comment typos.
1683 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1684 bytes sent in the client random.
