5 Changes between 0.9.6 and 0.9.6a [xx XXX 2000]
7 *) Add some EVP_add_digest_alias registrations (as found in
8 OpenSSL_add_all_digests()) to SSL_library_init()
9 aka OpenSSL_add_ssl_algorithms(). This provides improved
10 compatibility with peers using X.509 certificates
11 with unconventional AlgorithmIdentifier OIDs.
14 *) Fix for Irix with NO_ASM.
15 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
17 *) ./config script fixes.
18 [Ulf Moeller, Richard Levitte]
20 *) Fix 'openssl passwd -1'.
23 *) Change PKCS12_key_gen_asc() so it can cope with non null
24 terminated strings whose length is passed in the passlen
25 parameter, for example from PEM callbacks. This was done
26 by adding an extra length parameter to asc2uni().
27 [Steve Henson, reported by <oddissey@samsung.co.kr>]
29 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
30 call failed, free the DSA structure.
33 *) Fix to uni2asc() to cope with zero length Unicode strings.
34 These are present in some PKCS#12 files.
37 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
38 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
39 when writing a 32767 byte record.
40 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
42 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
43 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
45 (RSA objects have a reference count access to which is protected
46 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
47 so they are meant to be shared between threads.)
48 [Bodo Moeller, Geoff Thorpe; original patch submitted by
49 "Reddie, Steven" <Steven.Reddie@ca.com>]
51 *) Fix a deadlock in CRYPTO_mem_leaks().
54 *) rand_win.c fix for Borland C.
57 *) BN_rshift bugfix for n == 0.
60 *) Store verify_result within SSL_SESSION also for client side to
61 avoid potential security hole. (Re-used sessions on the client side
62 always resulted in verify_result==X509_V_OK, not using the original
63 result of the server certificate verification.)
66 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
67 SSL3_RT_APPLICATION_DATA, return 0.
68 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
72 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
73 releases, have been re-implemented by renaming the previous
74 implementations of ssl2_read and ssl3_read to ssl2_read_internal
75 and ssl3_read_internal, respectively, and adding 'peek' parameters
76 to them. The new ssl[23]_{read,peek} functions are calls to
77 ssl[23]_read_internal with the 'peek' flag set appropriately.
78 A 'peek' parameter has also been added to ssl3_read_bytes, which
79 does the actual work for ssl3_read_internal.
82 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
83 The previous value, 12, was not always sufficient for BN_mod_exp().
86 *) Fix typo in get_cert_by_subject() in by_dir.c
87 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
89 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
91 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
92 and not in SSL_clear because the latter is also used by the
93 accept/connect functions; previously, the settings made by
94 SSL_set_read_ahead would be lost during the handshake.
95 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
97 *) Correct util/mkdef.pl to be selective about disabled algorithms.
98 Previously, it would create entries for disableed algorithms no
102 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
104 *) In ssl23_get_client_hello, generate an error message when faced
105 with an initial SSL 3.0/TLS record that is too small to contain the
106 first two bytes of the ClientHello message, i.e. client_version.
107 (Note that this is a pathologic case that probably has never happened
108 in real life.) The previous approach was to use the version number
109 from the record header as a substitute; but our protocol choice
110 should not depend on that one because it is not authenticated
111 by the Finished messages.
114 *) More robust randomness gathering functions for Windows.
115 [Jeffrey Altman <jaltman@columbia.edu>]
117 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
118 not set then we don't setup the error code for issuer check errors
119 to avoid possibly overwriting other errors which the callback does
120 handle. If an application does set the flag then we assume it knows
121 what it is doing and can handle the new informational codes
125 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
126 a general "ANY" type, as such it should be able to decode anything
127 including tagged types. However it didn't check the class so it would
128 wrongly interpret tagged types in the same way as their universal
129 counterpart and unknown types were just rejected. Changed so that the
130 tagged and unknown types are handled in the same way as a SEQUENCE:
131 that is the encoding is stored intact. There is also a new type
132 "V_ASN1_OTHER" which is used when the class is not universal, in this
133 case we have no idea what the actual type is so we just lump them all
137 *) On VMS, stdout may very well lead to a file that is written to
138 in a record-oriented fashion. That means that every write() will
139 write a separate record, which will be read separately by the
140 programs trying to read from it. This can be very confusing.
142 The solution is to put a BIO filter in the way that will buffer
143 text until a linefeed is reached, and then write everything a
144 line at a time, so every record written will be an actual line,
145 not chunks of lines and not (usually doesn't happen, but I've
146 seen it once) several lines in one record. BIO_f_linebuffer() is
149 Currently, it's a VMS-only method, because that's where it has
150 been tested well enough.
153 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
154 it can return incorrect results.
155 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
156 but it was in 0.9.6-beta[12].)
159 *) Disable the check for content being present when verifying detached
160 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
161 include zero length content when signing messages.
164 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
165 BIO_ctrl (for BIO pairs).
168 *) Add DSO method for VMS.
171 *) Bug fix: Montgomery multiplication could produce results with the
175 *) Add RPM specification openssl.spec and modify it to build three
176 packages. The default package contains applications, application
177 documentation and run-time libraries. The devel package contains
178 include files, static libraries and function documentation. The
179 doc package contains the contents of the doc directory. The original
180 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
183 *) Add a large number of documentation files for many SSL routines.
184 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
186 *) Add a configuration entry for Sony News 4.
187 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
189 *) Don't set the two most significant bits to one when generating a
190 random number < q in the DSA library.
193 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
194 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
195 the underlying transport is blocking) if a handshake took place.
196 (The default behaviour is needed by applications such as s_client
197 and s_server that use select() to determine when to use SSL_read;
198 but for applications that know in advance when to expect data, it
199 just makes things more complicated.)
202 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
206 *) Add a few more EBCDIC conditionals that make `req' and `x509'
207 work better on such systems.
208 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
210 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
211 Update PKCS12_parse() so it copies the friendlyName and the
212 keyid to the certificates aux info.
215 *) Fix bug in PKCS7_verify() which caused an infinite loop
216 if there was more than one signature.
217 [Sven Uszpelkat <su@celocom.de>]
219 *) Major change in util/mkdef.pl to include extra information
220 about each symbol, as well as presentig variables as well
221 as functions. This change means that there's n more need
222 to rebuild the .num files when some algorithms are excluded.
225 *) Allow the verify time to be set by an application,
226 rather than always using the current time.
229 *) Phase 2 verify code reorganisation. The certificate
230 verify code now looks up an issuer certificate by a
231 number of criteria: subject name, authority key id
232 and key usage. It also verifies self signed certificates
233 by the same criteria. The main comparison function is
234 X509_check_issued() which performs these checks.
236 Lot of changes were necessary in order to support this
237 without completely rewriting the lookup code.
239 Authority and subject key identifier are now cached.
241 The LHASH 'certs' is X509_STORE has now been replaced
242 by a STACK_OF(X509_OBJECT). This is mainly because an
243 LHASH can't store or retrieve multiple objects with
246 As a result various functions (which were all internal
247 use only) have changed to handle the new X509_STORE
248 structure. This will break anything that messed round
249 with X509_STORE internally.
251 The functions X509_STORE_add_cert() now checks for an
252 exact match, rather than just subject name.
254 The X509_STORE API doesn't directly support the retrieval
255 of multiple certificates matching a given criteria, however
256 this can be worked round by performing a lookup first
257 (which will fill the cache with candidate certificates)
258 and then examining the cache for matches. This is probably
259 the best we can do without throwing out X509_LOOKUP
260 entirely (maybe later...).
262 The X509_VERIFY_CTX structure has been enhanced considerably.
264 All certificate lookup operations now go via a get_issuer()
265 callback. Although this currently uses an X509_STORE it
266 can be replaced by custom lookups. This is a simple way
267 to bypass the X509_STORE hackery necessary to make this
268 work and makes it possible to use more efficient techniques
269 in future. A very simple version which uses a simple
270 STACK for its trusted certificate store is also provided
271 using X509_STORE_CTX_trusted_stack().
273 The verify_cb() and verify() callbacks now have equivalents
274 in the X509_STORE_CTX structure.
276 X509_STORE_CTX also has a 'flags' field which can be used
277 to customise the verify behaviour.
280 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
281 excludes S/MIME capabilities.
284 *) When a certificate request is read in keep a copy of the
285 original encoding of the signed data and use it when outputing
286 again. Signatures then use the original encoding rather than
287 a decoded, encoded version which may cause problems if the
288 request is improperly encoded.
291 *) For consistency with other BIO_puts implementations, call
292 buffer_write(b, ...) directly in buffer_puts instead of calling
295 In BIO_puts, increment b->num_write as in BIO_write.
296 [Peter.Sylvester@EdelWeb.fr]
298 *) Fix BN_mul_word for the case where the word is 0. (We have to use
299 BN_zero, we may not return a BIGNUM with an array consisting of
303 *) Avoid calling abort() from within the library when problems are
304 detected, except if preprocessor symbols have been defined
305 (such as REF_CHECK, BN_DEBUG etc.).
308 *) New openssl application 'rsautl'. This utility can be
309 used for low level RSA operations. DER public key
310 BIO/fp routines also added.
313 *) New Configure entry and patches for compiling on QNX 4.
314 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
316 *) A demo state-machine implementation was sponsored by
317 Nuron (http://www.nuron.com/) and is now available in
321 *) New options added to the 'dgst' utility for signature
322 generation and verification.
325 *) Unrecognized PKCS#7 content types are now handled via a
326 catch all ASN1_TYPE structure. This allows unsupported
327 types to be stored as a "blob" and an application can
328 encode and decode it manually.
331 *) Fix various signed/unsigned issues to make a_strex.c
333 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
335 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
336 length if passed a buffer. ASN1_INTEGER_to_BN failed
337 if passed a NULL BN and its argument was negative.
338 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
340 *) Modification to PKCS#7 encoding routines to output definite
341 length encoding. Since currently the whole structures are in
342 memory there's not real point in using indefinite length
343 constructed encoding. However if OpenSSL is compiled with
344 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
347 *) Added BIO_vprintf() and BIO_vsnprintf().
350 *) Added more prefixes to parse for in the the strings written
351 through a logging bio, to cover all the levels that are available
352 through syslog. The prefixes are now:
354 PANIC, EMERG, EMR => LOG_EMERG
355 ALERT, ALR => LOG_ALERT
356 CRIT, CRI => LOG_CRIT
357 ERROR, ERR => LOG_ERR
358 WARNING, WARN, WAR => LOG_WARNING
359 NOTICE, NOTE, NOT => LOG_NOTICE
360 INFO, INF => LOG_INFO
361 DEBUG, DBG => LOG_DEBUG
363 and as before, if none of those prefixes are present at the
364 beginning of the string, LOG_ERR is chosen.
366 On Win32, the LOG_* levels are mapped according to this:
368 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
369 LOG_WARNING => EVENTLOG_WARNING_TYPE
370 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
374 *) Made it possible to reconfigure with just the configuration
375 argument "reconf" or "reconfigure". The command line arguments
376 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
377 and are retrieved from there when reconfiguring.
381 [Assar Westerlund <assar@sics.se>, Richard Levitte]
383 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
386 *) The obj_dat.pl script was messing up the sorting of object
387 names. The reason was that it compared the quoted version
388 of strings as a result "OCSP" > "OCSP Signing" because
389 " > SPACE. Changed script to store unquoted versions of
390 names and add quotes on output. It was also omitting some
391 names from the lookup table if they were given a default
392 value (that is if SN is missing it is given the same
393 value as LN and vice versa), these are now added on the
394 grounds that if an object has a name we should be able to
395 look it up. Finally added warning output when duplicate
396 short or long names are found.
399 *) Changes needed for Tandem NSK.
400 [Scott Uroff <scott@xypro.com>]
402 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
403 RSA_padding_check_SSLv23(), special padding was never detected
404 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
405 version rollback attacks was not effective.
407 In s23_clnt.c, don't use special rollback-attack detection padding
408 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
409 client; similarly, in s23_srvr.c, don't do the rollback check if
410 SSL 2.0 is the only protocol enabled in the server.
413 *) Make it possible to get hexdumps of unprintable data with 'openssl
414 asn1parse'. By implication, the functions ASN1_parse_dump() and
415 BIO_dump_indent() are added.
418 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
419 these print out strings and name structures based on various
420 flags including RFC2253 support and proper handling of
421 multibyte characters. Added options to the 'x509' utility
422 to allow the various flags to be set.
425 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
426 Also change the functions X509_cmp_current_time() and
427 X509_gmtime_adj() work with an ASN1_TIME structure,
428 this will enable certificates using GeneralizedTime in validity
432 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
433 negative public key encodings) on by default,
434 NO_NEG_PUBKEY_BUG can be set to disable it.
437 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
438 content octets. An i2c_ASN1_OBJECT is unnecessary because
439 the encoding can be trivially obtained from the structure.
442 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
443 not read locks (CRYPTO_r_[un]lock).
446 *) A first attempt at creating official support for shared
447 libraries through configuration. I've kept it so the
448 default is static libraries only, and the OpenSSL programs
449 are always statically linked for now, but there are
450 preparations for dynamic linking in place.
451 This has been tested on Linux and True64.
454 *) Randomness polling function for Win9x, as described in:
455 Peter Gutmann, Software Generation of Practically Strong
459 *) Fix so PRNG is seeded in req if using an already existing
463 *) New options to smime application. -inform and -outform
464 allow alternative formats for the S/MIME message including
465 PEM and DER. The -content option allows the content to be
466 specified separately. This should allow things like Netscape
467 form signing output easier to verify.
470 *) Fix the ASN1 encoding of tags using the 'long form'.
473 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
474 STRING types. These convert content octets to and from the
475 underlying type. The actual tag and length octets are
476 already assumed to have been read in and checked. These
477 are needed because all other string types have virtually
478 identical handling apart from the tag. By having versions
479 of the ASN1 functions that just operate on content octets
480 IMPLICIT tagging can be handled properly. It also allows
481 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
482 and ASN1_INTEGER are identical apart from the tag.
485 *) Change the handling of OID objects as follows:
487 - New object identifiers are inserted in objects.txt, following
488 the syntax given in objects.README.
489 - objects.pl is used to process obj_mac.num and create a new
491 - obj_dat.pl is used to create a new obj_dat.h, using the data in
494 This is currently kind of a hack, and the perl code in objects.pl
495 isn't very elegant, but it works as I intended. The simplest way
496 to check that it worked correctly is to look in obj_dat.h and
497 check the array nid_objs and make sure the objects haven't moved
498 around (this is important!). Additions are OK, as well as
499 consistent name changes.
502 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
505 *) Addition of the command line parameter '-rand file' to 'openssl req'.
506 The given file adds to whatever has already been seeded into the
507 random pool through the RANDFILE configuration file option or
508 environment variable, or the default random state file.
511 *) mkstack.pl now sorts each macro group into lexical order.
512 Previously the output order depended on the order the files
513 appeared in the directory, resulting in needless rewriting
517 *) Patches to make OpenSSL compile under Win32 again. Mostly
518 work arounds for the VC++ problem that it treats func() as
519 func(void). Also stripped out the parts of mkdef.pl that
520 added extra typesafe functions: these no longer exist.
523 *) Reorganisation of the stack code. The macros are now all
524 collected in safestack.h . Each macro is defined in terms of
525 a "stack macro" of the form SKM_<name>(type, a, b). The
526 DEBUG_SAFESTACK is now handled in terms of function casts,
527 this has the advantage of retaining type safety without the
528 use of additional functions. If DEBUG_SAFESTACK is not defined
529 then the non typesafe macros are used instead. Also modified the
530 mkstack.pl script to handle the new form. Needs testing to see
531 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
532 the default if no major problems. Similar behaviour for ASN1_SET_OF
536 *) When some versions of IIS use the 'NET' form of private key the
537 key derivation algorithm is different. Normally MD5(password) is
538 used as a 128 bit RC4 key. In the modified case
539 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
540 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
541 as the old Netscape_RSA functions except they have an additional
542 'sgckey' parameter which uses the modified algorithm. Also added
543 an -sgckey command line option to the rsa utility. Thanks to
544 Adrian Peck <bertie@ncipher.com> for posting details of the modified
545 algorithm to openssl-dev.
548 *) The evp_local.h macros were using 'c.##kname' which resulted in
549 invalid expansion on some systems (SCO 5.0.5 for example).
550 Corrected to 'c.kname'.
551 [Phillip Porch <root@theporch.com>]
553 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
554 a STACK of email addresses from a certificate or request, these look
555 in the subject name and the subject alternative name extensions and
556 omit any duplicate addresses.
559 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
560 This makes DSA verification about 2 % faster.
563 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
564 (meaning that now 2^5 values will be precomputed, which is only 4 KB
565 plus overhead for 1024 bit moduli).
566 This makes exponentiations about 0.5 % faster for 1024 bit
567 exponents (as measured by "openssl speed rsa2048").
570 *) Rename memory handling macros to avoid conflicts with other
572 Malloc => OPENSSL_malloc
573 Malloc_locked => OPENSSL_malloc_locked
574 Realloc => OPENSSL_realloc
578 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
579 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
583 [John Jarvie <jjarvie@newsguy.com>]
585 *) The type-safe stack code has been rejigged. It is now only compiled
586 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
587 by default all type-specific stack functions are "#define"d back to
588 standard stack functions. This results in more streamlined output
589 but retains the type-safety checking possibilities of the original
593 *) The STACK code has been cleaned up, and certain type declarations
594 that didn't make a lot of sense have been brought in line. This has
595 also involved a cleanup of sorts in safestack.h to more correctly
596 map type-safe stack functions onto their plain stack counterparts.
597 This work has also resulted in a variety of "const"ifications of
598 lots of the code, especially "_cmp" operations which should normally
599 be prototyped with "const" parameters anyway.
602 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
603 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
604 (The PRNG state consists of two parts, the large pool 'state' and 'md',
605 where all of 'md' is used each time the PRNG is used, but 'state'
606 is used only indexed by a cyclic counter. As entropy may not be
607 well distributed from the beginning, 'md' is important as a
608 chaining variable. However, the output function chains only half
609 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
610 all of 'md', and seeding with STATE_SIZE dummy bytes will result
611 in all of 'state' being rewritten, with the new values depending
612 on virtually all of 'md'. This overcomes the 80 bit limitation.)
615 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
616 the handshake is continued after ssl_verify_cert_chain();
617 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
618 can lead to 'unexplainable' connection aborts later.
619 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
621 *) Major EVP API cipher revision.
622 Add hooks for extra EVP features. This allows various cipher
623 parameters to be set in the EVP interface. Support added for variable
624 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
625 setting of RC2 and RC5 parameters.
627 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
630 Remove lots of duplicated code from the EVP library. For example *every*
631 cipher init() function handles the 'iv' in the same way according to the
632 cipher mode. They also all do nothing if the 'key' parameter is NULL and
633 for CFB and OFB modes they zero ctx->num.
635 New functionality allows removal of S/MIME code RC2 hack.
637 Most of the routines have the same form and so can be declared in terms
640 By shifting this to the top level EVP_CipherInit() it can be removed from
641 all individual ciphers. If the cipher wants to handle IVs or keys
642 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
645 Change lots of functions like EVP_EncryptUpdate() to now return a
646 value: although software versions of the algorithms cannot fail
647 any installed hardware versions can.
650 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
651 this option is set, tolerate broken clients that send the negotiated
652 protocol version number instead of the requested protocol version
656 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
657 i.e. non-zero for export ciphersuites, zero otherwise.
658 Previous versions had this flag inverted, inconsistent with
659 rsa_tmp_cb (..._TMP_RSA_CB).
660 [Bodo Moeller; problem reported by Amit Chopra]
662 *) Add missing DSA library text string. Work around for some IIS
663 key files with invalid SEQUENCE encoding.
666 *) Add a document (doc/standards.txt) that list all kinds of standards
667 and so on that are implemented in OpenSSL.
670 *) Enhance c_rehash script. Old version would mishandle certificates
671 with the same subject name hash and wouldn't handle CRLs at all.
672 Added -fingerprint option to crl utility, to support new c_rehash
676 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
679 *) Fix for SSL server purpose checking. Server checking was
680 rejecting certificates which had extended key usage present
681 but no ssl client purpose.
682 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
684 *) Make PKCS#12 code work with no password. The PKCS#12 spec
685 is a little unclear about how a blank password is handled.
686 Since the password in encoded as a BMPString with terminating
687 double NULL a zero length password would end up as just the
688 double NULL. However no password at all is different and is
689 handled differently in the PKCS#12 key generation code. NS
690 treats a blank password as zero length. MSIE treats it as no
691 password on export: but it will try both on import. We now do
692 the same: PKCS12_parse() tries zero length and no password if
693 the password is set to "" or NULL (NULL is now a valid password:
694 it wasn't before) as does the pkcs12 application.
697 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
698 perror when PEM_read_bio_X509_REQ fails, the error message must
699 be obtained from the error queue.
702 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
703 it in ERR_remove_state if appropriate, and change ERR_get_state
704 accordingly to avoid race conditions (this is necessary because
705 thread_hash is no longer constant once set).
708 *) Bugfix for linux-elf makefile.one.
711 *) RSA_get_default_method() will now cause a default
712 RSA_METHOD to be chosen if one doesn't exist already.
713 Previously this was only set during a call to RSA_new()
714 or RSA_new_method(NULL) meaning it was possible for
715 RSA_get_default_method() to return NULL.
718 *) Added native name translation to the existing DSO code
719 that will convert (if the flag to do so is set) filenames
720 that are sufficiently small and have no path information
721 into a canonical native form. Eg. "blah" converted to
722 "libblah.so" or "blah.dll" etc.
725 *) New function ERR_error_string_n(e, buf, len) which is like
726 ERR_error_string(e, buf), but writes at most 'len' bytes
727 including the 0 terminator. For ERR_error_string_n, 'buf'
729 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
731 *) CONF library reworked to become more general. A new CONF
732 configuration file reader "class" is implemented as well as a
733 new functions (NCONF_*, for "New CONF") to handle it. The now
734 old CONF_* functions are still there, but are reimplemented to
735 work in terms of the new functions. Also, a set of functions
736 to handle the internal storage of the configuration data is
737 provided to make it easier to write new configuration file
738 reader "classes" (I can definitely see something reading a
739 configuration file in XML format, for example), called _CONF_*,
740 or "the configuration storage API"...
742 The new configuration file reading functions are:
744 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
745 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
747 NCONF_default, NCONF_WIN32
749 NCONF_dump_fp, NCONF_dump_bio
751 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
752 NCONF_new creates a new CONF object. This works in the same way
753 as other interfaces in OpenSSL, like the BIO interface.
754 NCONF_dump_* dump the internal storage of the configuration file,
755 which is useful for debugging. All other functions take the same
756 arguments as the old CONF_* functions wth the exception of the
757 first that must be a `CONF *' instead of a `LHASH *'.
759 To make it easer to use the new classes with the old CONF_* functions,
760 the function CONF_set_default_method is provided.
763 *) Add '-tls1' option to 'openssl ciphers', which was already
764 mentioned in the documentation but had not been implemented.
765 (This option is not yet really useful because even the additional
766 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
769 *) Initial DSO code added into libcrypto for letting OpenSSL (and
770 OpenSSL-based applications) load shared libraries and bind to
771 them in a portable way.
772 [Geoff Thorpe, with contributions from Richard Levitte]
774 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
776 *) Make sure _lrotl and _lrotr are only used with MSVC.
778 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
779 (the default implementation of RAND_status).
781 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
782 to '-clrext' (= clear extensions), as intended and documented.
783 [Bodo Moeller; inconsistency pointed out by Michael Attili
786 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
787 was larger than the MD block size.
788 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
790 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
791 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
792 using the passed key: if the passed key was a private key the result
793 of X509_print(), for example, would be to print out all the private key
797 *) des_quad_cksum() byte order bug fix.
798 [Ulf Möller, using the problem description in krb4-0.9.7, where
799 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
801 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
803 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
805 *) For easily testing in shell scripts whether some command
806 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
807 returns with exit code 0 iff no command of the given name is available.
808 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
809 the output goes to stdout and nothing is printed to stderr.
810 Additional arguments are always ignored.
812 Since for each cipher there is a command of the same name,
813 the 'no-cipher' compilation switches can be tested this way.
815 ('openssl no-XXX' is not able to detect pseudo-commands such
816 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
819 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
822 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
823 is set; it will be thrown away anyway because each handshake creates
825 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
826 to parameters -- in previous versions (since OpenSSL 0.9.3) the
827 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
828 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
831 *) New s_client option -ign_eof: EOF at stdin is ignored, and
832 'Q' and 'R' lose their special meanings (quit/renegotiate).
833 This is part of what -quiet does; unlike -quiet, -ign_eof
834 does not suppress any output.
837 *) Add compatibility options to the purpose and trust code. The
838 purpose X509_PURPOSE_ANY is "any purpose" which automatically
839 accepts a certificate or CA, this was the previous behaviour,
840 with all the associated security issues.
842 X509_TRUST_COMPAT is the old trust behaviour: only and
843 automatically trust self signed roots in certificate store. A
844 new trust setting X509_TRUST_DEFAULT is used to specify that
845 a purpose has no associated trust setting and it should instead
846 use the value in the default purpose.
849 *) Fix the PKCS#8 DSA private key code so it decodes keys again
850 and fix a memory leak.
853 *) In util/mkerr.pl (which implements 'make errors'), preserve
854 reason strings from the previous version of the .c file, as
855 the default to have only downcase letters (and digits) in
856 automatically generated reasons codes is not always appropriate.
859 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
860 using strerror. Previously, ERR_reason_error_string() returned
861 library names as reason strings for SYSerr; but SYSerr is a special
862 case where small numbers are errno values, not library numbers.
865 *) Add '-dsaparam' option to 'openssl dhparam' application. This
866 converts DSA parameters into DH parameters. (When creating parameters,
867 DSA_generate_parameters is used.)
870 *) Include 'length' (recommended exponent length) in C code generated
871 by 'openssl dhparam -C'.
874 *) The second argument to set_label in perlasm was already being used
875 so couldn't be used as a "file scope" flag. Moved to third argument
879 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
880 instead of RAND_bytes for encryption IVs and salts.
883 *) Include RAND_status() into RAND_METHOD instead of implementing
884 it only for md_rand.c Otherwise replacing the PRNG by calling
885 RAND_set_rand_method would be impossible.
888 *) Don't let DSA_generate_key() enter an infinite loop if the random
889 number generation fails.
892 *) New 'rand' application for creating pseudo-random output.
895 *) Added configuration support for Linux/IA64
896 [Rolf Haberrecker <rolf@suse.de>]
898 *) Assembler module support for Mingw32.
901 *) Shared library support for HPUX (in shlib/).
902 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
904 *) Shared library support for Solaris gcc.
905 [Lutz Behnke <behnke@trustcenter.de>]
907 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
909 *) PKCS7_encrypt() was adding text MIME headers twice because they
910 were added manually and by SMIME_crlf_copy().
913 *) In bntest.c don't call BN_rand with zero bits argument.
914 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
916 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
917 case was implemented. This caused BN_div_recp() to fail occasionally.
920 *) Add an optional second argument to the set_label() in the perl
921 assembly language builder. If this argument exists and is set
922 to 1 it signals that the assembler should use a symbol whose
923 scope is the entire file, not just the current function. This
924 is needed with MASM which uses the format label:: for this scope.
925 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
927 *) Change the ASN1 types so they are typedefs by default. Before
928 almost all types were #define'd to ASN1_STRING which was causing
929 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
933 *) Change names of new functions to the new get1/get0 naming
934 convention: After 'get1', the caller owns a reference count
935 and has to call ..._free; 'get0' returns a pointer to some
936 data structure without incrementing reference counters.
937 (Some of the existing 'get' functions increment a reference
938 counter, some don't.)
939 Similarly, 'set1' and 'add1' functions increase reference
940 counters or duplicate objects.
943 *) Allow for the possibility of temp RSA key generation failure:
944 the code used to assume it always worked and crashed on failure.
947 *) Fix potential buffer overrun problem in BIO_printf().
948 [Ulf Möller, using public domain code by Patrick Powell; problem
949 pointed out by David Sacerdote <das33@cornell.edu>]
951 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
952 RAND_egd() and RAND_status(). In the command line application,
953 the EGD socket can be specified like a seed file using RANDFILE
957 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
958 Some CAs (e.g. Verisign) distribute certificates in this form.
961 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
962 list to exclude them. This means that no special compilation option
963 is needed to use anonymous DH: it just needs to be included in the
967 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
968 EVP_MD_type. The old functionality is available in a new macro called
969 EVP_MD_md(). Change code that uses it and update docs.
972 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
973 where the 'void *' argument is replaced by a function pointer argument.
974 Previously 'void *' was abused to point to functions, which works on
975 many platforms, but is not correct. As these functions are usually
976 called by macros defined in OpenSSL header files, most source code
977 should work without changes.
980 *) <openssl/opensslconf.h> (which is created by Configure) now contains
981 sections with information on -D... compiler switches used for
982 compiling the library so that applications can see them. To enable
983 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
984 must be defined. E.g.,
985 #define OPENSSL_ALGORITHM_DEFINES
986 #include <openssl/opensslconf.h>
987 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
988 [Richard Levitte, Ulf and Bodo Möller]
990 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
994 *) Change the 'other' type in certificate aux info to a STACK_OF
995 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
996 the required ASN1 format: arbitrary types determined by an OID.
999 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
1000 argument to 'req'. This is not because the function is newer or
1001 better than others it just uses the work 'NEW' in the certificate
1002 request header lines. Some software needs this.
1005 *) Reorganise password command line arguments: now passwords can be
1006 obtained from various sources. Delete the PEM_cb function and make
1007 it the default behaviour: i.e. if the callback is NULL and the
1008 usrdata argument is not NULL interpret it as a null terminated pass
1009 phrase. If usrdata and the callback are NULL then the pass phrase
1010 is prompted for as usual.
1013 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
1014 the support is automatically enabled. The resulting binaries will
1015 autodetect the card and use it if present.
1016 [Ben Laurie and Compaq Inc.]
1018 *) Work around for Netscape hang bug. This sends certificate request
1019 and server done in one record. Since this is perfectly legal in the
1020 SSL/TLS protocol it isn't a "bug" option and is on by default. See
1021 the bugs/SSLv3 entry for more info.
1024 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
1027 *) Add -rand argument to smime and pkcs12 applications and read/write
1031 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
1034 *) Add command line password options to the remaining applications.
1037 *) Bug fix for BN_div_recp() for numerators with an even number of
1041 *) More tests in bntest.c, and changed test_bn output.
1044 *) ./config recognizes MacOS X now.
1047 *) Bug fix for BN_div() when the first words of num and divsor are
1048 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
1051 *) Add support for various broken PKCS#8 formats, and command line
1052 options to produce them.
1055 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
1056 get temporary BIGNUMs from a BN_CTX.
1059 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
1063 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
1064 include a #define from the old name to the new. The original intent
1065 was that statically linked binaries could for example just call
1066 SSLeay_add_all_ciphers() to just add ciphers to the table and not
1067 link with digests. This never worked becayse SSLeay_add_all_digests()
1068 and SSLeay_add_all_ciphers() were in the same source file so calling
1069 one would link with the other. They are now in separate source files.
1072 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
1075 *) Use a less unusual form of the Miller-Rabin primality test (it used
1076 a binary algorithm for exponentiation integrated into the Miller-Rabin
1077 loop, our standard modexp algorithms are faster).
1080 *) Support for the EBCDIC character set completed.
1081 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
1083 *) Source code cleanups: use const where appropriate, eliminate casts,
1084 use void * instead of char * in lhash.
1087 *) Bugfix: ssl3_send_server_key_exchange was not restartable
1088 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
1089 this the server could overwrite ephemeral keys that the client
1093 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
1094 using 50 iterations of the Rabin-Miller test.
1096 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
1097 iterations of the Rabin-Miller test as required by the appendix
1098 to FIPS PUB 186[-1]) instead of DSA_is_prime.
1099 As BN_is_prime_fasttest includes trial division, DSA parameter
1100 generation becomes much faster.
1102 This implies a change for the callback functions in DSA_is_prime
1103 and DSA_generate_parameters: The callback function is called once
1104 for each positive witness in the Rabin-Miller test, not just
1105 occasionally in the inner loop; and the parameters to the
1106 callback function now provide an iteration count for the outer
1107 loop rather than for the current invocation of the inner loop.
1108 DSA_generate_parameters additionally can call the callback
1109 function with an 'iteration count' of -1, meaning that a
1110 candidate has passed the trial division test (when q is generated
1111 from an application-provided seed, trial division is skipped).
1114 *) New function BN_is_prime_fasttest that optionally does trial
1115 division before starting the Rabin-Miller test and has
1116 an additional BN_CTX * argument (whereas BN_is_prime always
1117 has to allocate at least one BN_CTX).
1118 'callback(1, -1, cb_arg)' is called when a number has passed the
1119 trial division stage.
1122 *) Fix for bug in CRL encoding. The validity dates weren't being handled
1126 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
1129 *) New function BN_pseudo_rand().
1132 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
1133 bignum version of BN_from_montgomery() with the working code from
1134 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
1138 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
1139 made it impossible to use the same SSL_SESSION data structure in
1140 SSL2 clients in multiple threads.
1143 *) The return value of RAND_load_file() no longer counts bytes obtained
1144 by stat(). RAND_load_file(..., -1) is new and uses the complete file
1145 to seed the PRNG (previously an explicit byte count was required).
1146 [Ulf Möller, Bodo Möller]
1148 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
1149 used (char *) instead of (void *) and had casts all over the place.
1152 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
1155 *) Retain source code compatibility for BN_prime_checks macro:
1156 BN_is_prime(..., BN_prime_checks, ...) now uses
1157 BN_prime_checks_for_size to determine the appropriate number of
1158 Rabin-Miller iterations.
1161 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
1162 DH_CHECK_P_NOT_SAFE_PRIME.
1163 (Check if this is true? OpenPGP calls them "strong".)
1166 *) Merge the functionality of "dh" and "gendh" programs into a new program
1167 "dhparam". The old programs are retained for now but will handle DH keys
1168 (instead of parameters) in future.
1171 *) Make the ciphers, s_server and s_client programs check the return values
1172 when a new cipher list is set.
1175 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
1176 ciphers. Before when the 56bit ciphers were enabled the sorting was
1179 The syntax for the cipher sorting has been extended to support sorting by
1180 cipher-strength (using the strength_bits hard coded in the tables).
1181 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
1183 Fix a bug in the cipher-command parser: when supplying a cipher command
1184 string with an "undefined" symbol (neither command nor alphanumeric
1185 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
1186 an error is flagged.
1188 Due to the strength-sorting extension, the code of the
1189 ssl_create_cipher_list() function was completely rearranged. I hope that
1190 the readability was also increased :-)
1191 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1193 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
1194 for the first serial number and places 2 in the serial number file. This
1195 avoids problems when the root CA is created with serial number zero and
1196 the first user certificate has the same issuer name and serial number
1200 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
1201 the new code. Add documentation for this stuff.
1204 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
1205 X509_*() to X509at_*() on the grounds that they don't handle X509
1206 structures and behave in an analagous way to the X509v3 functions:
1207 they shouldn't be called directly but wrapper functions should be used
1210 So we also now have some wrapper functions that call the X509at functions
1211 when passed certificate requests. (TO DO: similar things can be done with
1212 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
1213 things. Some of these need some d2i or i2d and print functionality
1214 because they handle more complex structures.)
1217 *) Add missing #ifndefs that caused missing symbols when building libssl
1218 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
1219 NO_RSA in ssl/s2*.c.
1220 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
1222 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
1223 has a return value which indicates the quality of the random data
1224 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
1225 error queue. New function RAND_pseudo_bytes() generates output that is
1226 guaranteed to be unique but not unpredictable. RAND_add is like
1227 RAND_seed, but takes an extra argument for an entropy estimate
1228 (RAND_seed always assumes full entropy).
1231 *) Do more iterations of Rabin-Miller probable prime test (specifically,
1232 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
1233 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
1234 in crypto/bn/bn_prime.c for the complete table). This guarantees a
1235 false-positive rate of at most 2^-80 for random input.
1238 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
1241 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
1242 in the 0.9.5 release), this returns the chain
1243 from an X509_CTX structure with a dup of the stack and all
1244 the X509 reference counts upped: so the stack will exist
1245 after X509_CTX_cleanup() has been called. Modify pkcs12.c
1248 Also make SSL_SESSION_print() print out the verify return
1252 *) Add manpage for the pkcs12 command. Also change the default
1253 behaviour so MAC iteration counts are used unless the new
1254 -nomaciter option is used. This improves file security and
1255 only older versions of MSIE (4.0 for example) need it.
1258 *) Honor the no-xxx Configure options when creating .DEF files.
1261 *) Add PKCS#10 attributes to field table: challengePassword,
1262 unstructuredName and unstructuredAddress. These are taken from
1263 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
1264 international characters are used.
1266 More changes to X509_ATTRIBUTE code: allow the setting of types
1267 based on strings. Remove the 'loc' parameter when adding
1268 attributes because these will be a SET OF encoding which is sorted
1272 *) Initial changes to the 'req' utility to allow request generation
1273 automation. This will allow an application to just generate a template
1274 file containing all the field values and have req construct the
1277 Initial support for X509_ATTRIBUTE handling. Stacks of these are
1278 used all over the place including certificate requests and PKCS#7
1279 structures. They are currently handled manually where necessary with
1280 some primitive wrappers for PKCS#7. The new functions behave in a
1281 manner analogous to the X509 extension functions: they allow
1282 attributes to be looked up by NID and added.
1284 Later something similar to the X509V3 code would be desirable to
1285 automatically handle the encoding, decoding and printing of the
1286 more complex types. The string types like challengePassword can
1287 be handled by the string table functions.
1289 Also modified the multi byte string table handling. Now there is
1290 a 'global mask' which masks out certain types. The table itself
1291 can use the flag STABLE_NO_MASK to ignore the mask setting: this
1292 is useful when for example there is only one permissible type
1293 (as in countryName) and using the mask might result in no valid
1297 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
1298 SSL_get_peer_finished to allow applications to obtain the latest
1299 Finished messages sent to the peer or expected from the peer,
1300 respectively. (SSL_get_peer_finished is usually the Finished message
1301 actually received from the peer, otherwise the protocol will be aborted.)
1303 As the Finished message are message digests of the complete handshake
1304 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
1305 be used for external authentication procedures when the authentication
1306 provided by SSL/TLS is not desired or is not enough.
1309 *) Enhanced support for Alpha Linux is added. Now ./config checks if
1310 the host supports BWX extension and if Compaq C is present on the
1311 $PATH. Just exploiting of the BWX extension results in 20-30%
1312 performance kick for some algorithms, e.g. DES and RC4 to mention
1313 a couple. Compaq C in turn generates ~20% faster code for MD5 and
1317 *) Add support for MS "fast SGC". This is arguably a violation of the
1318 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
1319 weak crypto and after checking the certificate is SGC a second one
1320 with strong crypto. MS SGC stops the first handshake after receiving
1321 the server certificate message and sends a second client hello. Since
1322 a server will typically do all the time consuming operations before
1323 expecting any further messages from the client (server key exchange
1324 is the most expensive) there is little difference between the two.
1326 To get OpenSSL to support MS SGC we have to permit a second client
1327 hello message after we have sent server done. In addition we have to
1328 reset the MAC if we do get this second client hello.
1331 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
1332 if a DER encoded private key is RSA or DSA traditional format. Changed
1333 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
1334 format DER encoded private key. Newer code should use PKCS#8 format which
1335 has the key type encoded in the ASN1 structure. Added DER private key
1336 support to pkcs8 application.
1339 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
1340 ciphersuites has been selected (as required by the SSL 3/TLS 1
1341 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
1342 is set, we interpret this as a request to violate the specification
1343 (the worst that can happen is a handshake failure, and 'correct'
1344 behaviour would result in a handshake failure anyway).
1347 *) In SSL_CTX_add_session, take into account that there might be multiple
1348 SSL_SESSION structures with the same session ID (e.g. when two threads
1349 concurrently obtain them from an external cache).
1350 The internal cache can handle only one SSL_SESSION with a given ID,
1351 so if there's a conflict, we now throw out the old one to achieve
1355 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
1356 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
1357 some routines that use cipher OIDs: some ciphers do not have OIDs
1358 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
1362 *) Simplify the trust setting structure and code. Now we just have
1363 two sequences of OIDs for trusted and rejected settings. These will
1364 typically have values the same as the extended key usage extension
1365 and any application specific purposes.
1367 The trust checking code now has a default behaviour: it will just
1368 check for an object with the same NID as the passed id. Functions can
1369 be provided to override either the default behaviour or the behaviour
1370 for a given id. SSL client, server and email already have functions
1371 in place for compatibility: they check the NID and also return "trusted"
1372 if the certificate is self signed.
1375 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
1376 traditional format into an EVP_PKEY structure.
1379 *) Add a password callback function PEM_cb() which either prompts for
1380 a password if usr_data is NULL or otherwise assumes it is a null
1381 terminated password. Allow passwords to be passed on command line
1382 environment or config files in a few more utilities.
1385 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
1386 keys. Add some short names for PKCS#8 PBE algorithms and allow them
1387 to be specified on the command line for the pkcs8 and pkcs12 utilities.
1388 Update documentation.
1391 *) Support for ASN1 "NULL" type. This could be handled before by using
1392 ASN1_TYPE but there wasn't any function that would try to read a NULL
1393 and produce an error if it couldn't. For compatibility we also have
1394 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
1395 don't allocate anything because they don't need to.
1398 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
1400 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
1402 *) Rebuild of the memory allocation routines used by OpenSSL code and
1403 possibly others as well. The purpose is to make an interface that
1404 provide hooks so anyone can build a separate set of allocation and
1405 deallocation routines to be used by OpenSSL, for example memory
1406 pool implementations, or something else, which was previously hard
1407 since Malloc(), Realloc() and Free() were defined as macros having
1408 the values malloc, realloc and free, respectively (except for Win32
1409 compilations). The same is provided for memory debugging code.
1410 OpenSSL already comes with functionality to find memory leaks, but
1411 this gives people a chance to debug other memory problems.
1413 With these changes, a new set of functions and macros have appeared:
1415 CRYPTO_set_mem_debug_functions() [F]
1416 CRYPTO_get_mem_debug_functions() [F]
1417 CRYPTO_dbg_set_options() [F]
1418 CRYPTO_dbg_get_options() [F]
1419 CRYPTO_malloc_debug_init() [M]
1421 The memory debug functions are NULL by default, unless the library
1422 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
1423 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
1424 gives the standard debugging functions that come with OpenSSL) or
1425 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
1426 provided by the library user) must be used. When the standard
1427 debugging functions are used, CRYPTO_dbg_set_options can be used to
1428 request additional information:
1429 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
1430 the CRYPTO_MDEBUG_xxx macro when compiling the library.
1432 Also, things like CRYPTO_set_mem_functions will always give the
1433 expected result (the new set of functions is used for allocation
1434 and deallocation) at all times, regardless of platform and compiler
1437 To finish it up, some functions that were never use in any other
1438 way than through macros have a new API and new semantic:
1441 CRYPTO_dbg_realloc()
1444 All macros of value have retained their old syntax.
1445 [Richard Levitte and Bodo Moeller]
1447 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
1448 ordering of SMIMECapabilities wasn't in "strength order" and there
1449 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
1453 *) Some ASN1 types with illegal zero length encoding (INTEGER,
1454 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
1455 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
1457 *) Merge in my S/MIME library for OpenSSL. This provides a simple
1458 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
1459 functionality to handle multipart/signed properly) and a utility
1460 called 'smime' to call all this stuff. This is based on code I
1461 originally wrote for Celo who have kindly allowed it to be
1462 included in OpenSSL.
1465 *) Add variants des_set_key_checked and des_set_key_unchecked of
1466 des_set_key (aka des_key_sched). Global variable des_check_key
1467 decides which of these is called by des_set_key; this way
1468 des_check_key behaves as it always did, but applications and
1469 the library itself, which was buggy for des_check_key == 1,
1470 have a cleaner way to pick the version they need.
1473 *) New function PKCS12_newpass() which changes the password of a
1477 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
1478 dynamic mix. In both cases the ids can be used as an index into the
1479 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
1480 functions so they accept a list of the field values and the
1481 application doesn't need to directly manipulate the X509_TRUST
1485 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
1489 *) Modify the way the V3 extension code looks up extensions. This now
1490 works in a similar way to the object code: we have some "standard"
1491 extensions in a static table which is searched with OBJ_bsearch()
1492 and the application can add dynamic ones if needed. The file
1493 crypto/x509v3/ext_dat.h now has the info: this file needs to be
1494 updated whenever a new extension is added to the core code and kept
1495 in ext_nid order. There is a simple program 'tabtest.c' which checks
1496 this. New extensions are not added too often so this file can readily
1497 be maintained manually.
1499 There are two big advantages in doing things this way. The extensions
1500 can be looked up immediately and no longer need to be "added" using
1501 X509V3_add_standard_extensions(): this function now does nothing.
1502 [Side note: I get *lots* of email saying the extension code doesn't
1503 work because people forget to call this function]
1504 Also no dynamic allocation is done unless new extensions are added:
1505 so if we don't add custom extensions there is no need to call
1506 X509V3_EXT_cleanup().
1509 *) Modify enc utility's salting as follows: make salting the default. Add a
1510 magic header, so unsalted files fail gracefully instead of just decrypting
1511 to garbage. This is because not salting is a big security hole, so people
1512 should be discouraged from doing it.
1515 *) Fixes and enhancements to the 'x509' utility. It allowed a message
1516 digest to be passed on the command line but it only used this
1517 parameter when signing a certificate. Modified so all relevant
1518 operations are affected by the digest parameter including the
1519 -fingerprint and -x509toreq options. Also -x509toreq choked if a
1520 DSA key was used because it didn't fix the digest.
1523 *) Initial certificate chain verify code. Currently tests the untrusted
1524 certificates for consistency with the verify purpose (which is set
1525 when the X509_STORE_CTX structure is set up) and checks the pathlength.
1527 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
1528 this is because it will reject chains with invalid extensions whereas
1529 every previous version of OpenSSL and SSLeay made no checks at all.
1531 Trust code: checks the root CA for the relevant trust settings. Trust
1532 settings have an initial value consistent with the verify purpose: e.g.
1533 if the verify purpose is for SSL client use it expects the CA to be
1534 trusted for SSL client use. However the default value can be changed to
1535 permit custom trust settings: one example of this would be to only trust
1536 certificates from a specific "secure" set of CAs.
1538 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
1539 which should be used for version portability: especially since the
1540 verify structure is likely to change more often now.
1542 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
1543 to set them. If not set then assume SSL clients will verify SSL servers
1546 Two new options to the verify program: -untrusted allows a set of
1547 untrusted certificates to be passed in and -purpose which sets the
1548 intended purpose of the certificate. If a purpose is set then the
1549 new chain verify code is used to check extension consistency.
1552 *) Support for the authority information access extension.
1555 *) Modify RSA and DSA PEM read routines to transparently handle
1556 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
1557 public keys in a format compatible with certificate
1558 SubjectPublicKeyInfo structures. Unfortunately there were already
1559 functions called *_PublicKey_* which used various odd formats so
1560 these are retained for compatibility: however the DSA variants were
1561 never in a public release so they have been deleted. Changed dsa/rsa
1562 utilities to handle the new format: note no releases ever handled public
1563 keys so we should be OK.
1565 The primary motivation for this change is to avoid the same fiasco
1566 that dogs private keys: there are several incompatible private key
1567 formats some of which are standard and some OpenSSL specific and
1568 require various evil hacks to allow partial transparent handling and
1569 even then it doesn't work with DER formats. Given the option anything
1570 other than PKCS#8 should be dumped: but the other formats have to
1571 stay in the name of compatibility.
1573 With public keys and the benefit of hindsight one standard format
1574 is used which works with EVP_PKEY, RSA or DSA structures: though
1575 it clearly returns an error if you try to read the wrong kind of key.
1577 Added a -pubkey option to the 'x509' utility to output the public key.
1578 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
1579 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
1580 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
1581 that do the same as the EVP_PKEY_assign_*() except they up the
1582 reference count of the added key (they don't "swallow" the
1586 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
1587 CRLs would fail if the file contained no certificates or no CRLs:
1588 added a new function to read in both types and return the number
1589 read: this means that if none are read it will be an error. The
1590 DER versions of the certificate and CRL reader would always fail
1591 because it isn't possible to mix certificates and CRLs in DER format
1592 without choking one or the other routine. Changed this to just read
1593 a certificate: this is the best we can do. Also modified the code
1594 in apps/verify.c to take notice of return codes: it was previously
1595 attempting to read in certificates from NULL pointers and ignoring
1596 any errors: this is one reason why the cert and CRL reader seemed
1597 to work. It doesn't check return codes from the default certificate
1598 routines: these may well fail if the certificates aren't installed.
1601 *) Code to support otherName option in GeneralName.
1604 *) First update to verify code. Change the verify utility
1605 so it warns if it is passed a self signed certificate:
1606 for consistency with the normal behaviour. X509_verify
1607 has been modified to it will now verify a self signed
1608 certificate if *exactly* the same certificate appears
1609 in the store: it was previously impossible to trust a
1610 single self signed certificate. This means that:
1611 openssl verify ss.pem
1612 now gives a warning about a self signed certificate but
1613 openssl verify -CAfile ss.pem ss.pem
1617 *) For servers, store verify_result in SSL_SESSION data structure
1618 (and add it to external session representation).
1619 This is needed when client certificate verifications fails,
1620 but an application-provided verification callback (set by
1621 SSL_CTX_set_cert_verify_callback) allows accepting the session
1622 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
1623 but returns 1): When the session is reused, we have to set
1624 ssl->verify_result to the appropriate error code to avoid
1626 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
1628 *) Fix a bug in the new PKCS#7 code: it didn't consider the
1629 case in PKCS7_dataInit() where the signed PKCS7 structure
1630 didn't contain any existing data because it was being created.
1631 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
1633 *) Add a salt to the key derivation routines in enc.c. This
1634 forms the first 8 bytes of the encrypted file. Also add a
1635 -S option to allow a salt to be input on the command line.
1638 *) New function X509_cmp(). Oddly enough there wasn't a function
1639 to compare two certificates. We do this by working out the SHA1
1640 hash and comparing that. X509_cmp() will be needed by the trust
1644 *) SSL_get1_session() is like SSL_get_session(), but increments
1645 the reference count in the SSL_SESSION returned.
1646 [Geoff Thorpe <geoff@eu.c2.net>]
1648 *) Fix for 'req': it was adding a null to request attributes.
1649 Also change the X509_LOOKUP and X509_INFO code to handle
1650 certificate auxiliary information.
1653 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
1657 *) Add the possibility to add extra information to the memory leak
1658 detecting output, to form tracebacks, showing from where each
1659 allocation was originated: CRYPTO_push_info("constant string") adds
1660 the string plus current file name and line number to a per-thread
1661 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
1662 is like calling CYRPTO_pop_info() until the stack is empty.
1663 Also updated memory leak detection code to be multi-thread-safe.
1666 *) Add options -text and -noout to pkcs7 utility and delete the
1667 encryption options which never did anything. Update docs.
1670 *) Add options to some of the utilities to allow the pass phrase
1671 to be included on either the command line (not recommended on
1672 OSes like Unix) or read from the environment. Update the
1673 manpages and fix a few bugs.
1676 *) Add a few manpages for some of the openssl commands.
1679 *) Fix the -revoke option in ca. It was freeing up memory twice,
1680 leaking and not finding already revoked certificates.
1683 *) Extensive changes to support certificate auxiliary information.
1684 This involves the use of X509_CERT_AUX structure and X509_AUX
1685 functions. An X509_AUX function such as PEM_read_X509_AUX()
1686 can still read in a certificate file in the usual way but it
1687 will also read in any additional "auxiliary information". By
1688 doing things this way a fair degree of compatibility can be
1689 retained: existing certificates can have this information added
1690 using the new 'x509' options.
1692 Current auxiliary information includes an "alias" and some trust
1693 settings. The trust settings will ultimately be used in enhanced
1694 certificate chain verification routines: currently a certificate
1695 can only be trusted if it is self signed and then it is trusted
1699 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
1700 The problem was that one of the replacement routines had not been working
1701 since SSLeay releases. For now the offending routine has been replaced
1702 with non-optimised assembler. Even so, this now gives around 95%
1703 performance improvement for 1024 bit RSA signs.
1706 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
1707 handling. Most clients have the effective key size in bits equal to
1708 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
1709 A few however don't do this and instead use the size of the decrypted key
1710 to determine the RC2 key length and the AlgorithmIdentifier to determine
1711 the effective key length. In this case the effective key length can still
1712 be 40 bits but the key length can be 168 bits for example. This is fixed
1713 by manually forcing an RC2 key into the EVP_PKEY structure because the
1714 EVP code can't currently handle unusual RC2 key sizes: it always assumes
1715 the key length and effective key length are equal.
1718 *) Add a bunch of functions that should simplify the creation of
1719 X509_NAME structures. Now you should be able to do:
1720 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
1721 and have it automatically work out the correct field type and fill in
1722 the structures. The more adventurous can try:
1723 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
1724 and it will (hopefully) work out the correct multibyte encoding.
1727 *) Change the 'req' utility to use the new field handling and multibyte
1728 copy routines. Before the DN field creation was handled in an ad hoc
1729 way in req, ca, and x509 which was rather broken and didn't support
1730 BMPStrings or UTF8Strings. Since some software doesn't implement
1731 BMPStrings or UTF8Strings yet, they can be enabled using the config file
1732 using the dirstring_type option. See the new comment in the default
1733 openssl.cnf for more info.
1736 *) Make crypto/rand/md_rand.c more robust:
1737 - Assure unique random numbers after fork().
1738 - Make sure that concurrent threads access the global counter and
1739 md serializably so that we never lose entropy in them
1740 or use exactly the same state in multiple threads.
1741 Access to the large state is not always serializable because
1742 the additional locking could be a performance killer, and
1743 md should be large enough anyway.
1746 *) New file apps/app_rand.c with commonly needed functionality
1747 for handling the random seed file.
1749 Use the random seed file in some applications that previously did not:
1751 dsaparam -genkey (which also ignored its '-rand' option),
1754 x509 (when signing).
1755 Except on systems with /dev/urandom, it is crucial to have a random
1756 seed file at least for key creation, DSA signing, and for DH exchanges;
1757 for RSA signatures we could do without one.
1759 gendh and gendsa (unlike genrsa) used to read only the first byte
1760 of each file listed in the '-rand' option. The function as previously
1761 found in genrsa is now in app_rand.c and is used by all programs
1762 that support '-rand'.
1765 *) In RAND_write_file, use mode 0600 for creating files;
1766 don't just chmod when it may be too late.
1769 *) Report an error from X509_STORE_load_locations
1770 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
1773 *) New function ASN1_mbstring_copy() this copies a string in either
1774 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
1775 into an ASN1_STRING type. A mask of permissible types is passed
1776 and it chooses the "minimal" type to use or an error if not type
1780 *) Add function equivalents to the various macros in asn1.h. The old
1781 macros are retained with an M_ prefix. Code inside the library can
1782 use the M_ macros. External code (including the openssl utility)
1783 should *NOT* in order to be "shared library friendly".
1786 *) Add various functions that can check a certificate's extensions
1787 to see if it usable for various purposes such as SSL client,
1788 server or S/MIME and CAs of these types. This is currently
1789 VERY EXPERIMENTAL but will ultimately be used for certificate chain
1790 verification. Also added a -purpose flag to x509 utility to
1791 print out all the purposes.
1794 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
1798 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
1799 for, obtain and decode and extension and obtain its critical flag.
1800 This allows all the necessary extension code to be handled in a
1801 single function call.
1804 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
1805 platforms. See crypto/rc4/rc4_enc.c for further details.
1808 *) New -noout option to asn1parse. This causes no output to be produced
1809 its main use is when combined with -strparse and -out to extract data
1810 from a file (which may not be in ASN.1 format).
1813 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
1814 when producing the local key id.
1815 [Richard Levitte <levitte@stacken.kth.se>]
1817 *) New option -dhparam in s_server. This allows a DH parameter file to be
1818 stated explicitly. If it is not stated then it tries the first server
1819 certificate file. The previous behaviour hard coded the filename
1823 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
1824 a public key to be input or output. For example:
1825 openssl rsa -in key.pem -pubout -out pubkey.pem
1826 Also added necessary DSA public key functions to handle this.
1829 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
1830 in the message. This was handled by allowing
1831 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
1832 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
1834 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
1835 to the end of the strings whereas this didn't. This would cause problems
1836 if strings read with d2i_ASN1_bytes() were later modified.
1837 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
1839 *) Fix for base64 decode bug. When a base64 bio reads only one line of
1840 data and it contains EOF it will end up returning an error. This is
1841 caused by input 46 bytes long. The cause is due to the way base64
1842 BIOs find the start of base64 encoded data. They do this by trying a
1843 trial decode on each line until they find one that works. When they
1844 do a flag is set and it starts again knowing it can pass all the
1845 data directly through the decoder. Unfortunately it doesn't reset
1846 the context it uses. This means that if EOF is reached an attempt
1847 is made to pass two EOFs through the context and this causes the
1848 resulting error. This can also cause other problems as well. As is
1849 usual with these problems it takes *ages* to find and the fix is
1850 trivial: move one line.
1851 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
1853 *) Ugly workaround to get s_client and s_server working under Windows. The
1854 old code wouldn't work because it needed to select() on sockets and the
1855 tty (for keypresses and to see if data could be written). Win32 only
1856 supports select() on sockets so we select() with a 1s timeout on the
1857 sockets and then see if any characters are waiting to be read, if none
1858 are present then we retry, we also assume we can always write data to
1859 the tty. This isn't nice because the code then blocks until we've
1860 received a complete line of data and it is effectively polling the
1861 keyboard at 1s intervals: however it's quite a bit better than not
1862 working at all :-) A dedicated Windows application might handle this
1863 with an event loop for example.
1866 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
1867 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
1868 will be called when RSA_sign() and RSA_verify() are used. This is useful
1869 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
1870 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
1871 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
1872 This necessitated the support of an extra signature type NID_md5_sha1
1873 for SSL signatures and modifications to the SSL library to use it instead
1874 of calling RSA_public_decrypt() and RSA_private_encrypt().
1877 *) Add new -verify -CAfile and -CApath options to the crl program, these
1878 will lookup a CRL issuers certificate and verify the signature in a
1879 similar way to the verify program. Tidy up the crl program so it
1880 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
1881 less strict. It will now permit CRL extensions even if it is not
1882 a V2 CRL: this will allow it to tolerate some broken CRLs.
1885 *) Initialize all non-automatic variables each time one of the openssl
1886 sub-programs is started (this is necessary as they may be started
1887 multiple times from the "OpenSSL>" prompt).
1888 [Lennart Bang, Bodo Moeller]
1890 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
1891 removing all other RSA functionality (this is what NO_RSA does). This
1892 is so (for example) those in the US can disable those operations covered
1893 by the RSA patent while allowing storage and parsing of RSA keys and RSA
1897 *) Non-copying interface to BIO pairs.
1898 (still largely untested)
1901 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
1902 ASCII string. This was handled independently in various places before.
1905 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
1906 UTF8 strings a character at a time.
1909 *) Use client_version from client hello to select the protocol
1910 (s23_srvr.c) and for RSA client key exchange verification
1911 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
1914 *) Add various utility functions to handle SPKACs, these were previously
1915 handled by poking round in the structure internals. Added new function
1916 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
1917 print, verify and generate SPKACs. Based on an original idea from
1918 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
1921 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
1924 *) Allow the config file extension section to be overwritten on the
1925 command line. Based on an original idea from Massimiliano Pala
1926 <madwolf@comune.modena.it>. The new option is called -extensions
1927 and can be applied to ca, req and x509. Also -reqexts to override
1928 the request extensions in req and -crlexts to override the crl extensions
1932 *) Add new feature to the SPKAC handling in ca. Now you can include
1933 the same field multiple times by preceding it by "XXXX." for example:
1936 this is the same syntax as used in the req config file.
1939 *) Allow certificate extensions to be added to certificate requests. These
1940 are specified in a 'req_extensions' option of the req section of the
1941 config file. They can be printed out with the -text option to req but
1942 are otherwise ignored at present.
1945 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
1946 data read consists of only the final block it would not decrypted because
1947 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
1948 A misplaced 'break' also meant the decrypted final block might not be
1949 copied until the next read.
1952 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
1953 a few extra parameters to the DH structure: these will be useful if
1954 for example we want the value of 'q' or implement X9.42 DH.
1957 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
1958 provides hooks that allow the default DSA functions or functions on a
1959 "per key" basis to be replaced. This allows hardware acceleration and
1960 hardware key storage to be handled without major modification to the
1961 library. Also added low level modexp hooks and CRYPTO_EX structure and
1962 associated functions.
1965 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
1966 as "read only": it can't be written to and the buffer it points to will
1967 not be freed. Reading from a read only BIO is much more efficient than
1968 a normal memory BIO. This was added because there are several times when
1969 an area of memory needs to be read from a BIO. The previous method was
1970 to create a memory BIO and write the data to it, this results in two
1971 copies of the data and an O(n^2) reading algorithm. There is a new
1972 function BIO_new_mem_buf() which creates a read only memory BIO from
1973 an area of memory. Also modified the PKCS#7 routines to use read only
1977 *) Bugfix: ssl23_get_client_hello did not work properly when called in
1978 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
1979 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
1980 but a retry condition occured while trying to read the rest.
1983 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
1984 NID_pkcs7_encrypted by default: this was wrong since this should almost
1985 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
1986 the encrypted data type: this is a more sensible place to put it and it
1987 allows the PKCS#12 code to be tidied up that duplicated this
1991 *) Changed obj_dat.pl script so it takes its input and output files on
1992 the command line. This should avoid shell escape redirection problems
1996 *) Initial support for certificate extension requests, these are included
1997 in things like Xenroll certificate requests. Included functions to allow
1998 extensions to be obtained and added.
2001 *) -crlf option to s_client and s_server for sending newlines as
2002 CRLF (as required by many protocols).
2005 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
2007 *) Install libRSAglue.a when OpenSSL is built with RSAref.
2008 [Ralf S. Engelschall]
2010 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
2011 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
2013 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
2017 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
2018 DH parameters/keys (q is lost during that conversion, but the resulting
2019 DH parameters contain its length).
2021 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
2022 much faster than DH_generate_parameters (which creates parameters
2023 where p = 2*q + 1), and also the smaller q makes DH computations
2024 much more efficient (160-bit exponentiation instead of 1024-bit
2025 exponentiation); so this provides a convenient way to support DHE
2026 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
2027 utter importance to use
2028 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2030 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2031 when such DH parameters are used, because otherwise small subgroup
2032 attacks may become possible!
2035 *) Avoid memory leak in i2d_DHparams.
2038 *) Allow the -k option to be used more than once in the enc program:
2039 this allows the same encrypted message to be read by multiple recipients.
2042 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
2043 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
2044 it will always use the numerical form of the OID, even if it has a short
2048 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
2049 method only got called if p,q,dmp1,dmq1,iqmp components were present,
2050 otherwise bn_mod_exp was called. In the case of hardware keys for example
2051 no private key components need be present and it might store extra data
2052 in the RSA structure, which cannot be accessed from bn_mod_exp.
2053 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
2054 private key operations.
2057 *) Added support for SPARC Linux.
2060 *) pem_password_cb function type incompatibly changed from
2061 typedef int pem_password_cb(char *buf, int size, int rwflag);
2063 ....(char *buf, int size, int rwflag, void *userdata);
2064 so that applications can pass data to their callbacks:
2065 The PEM[_ASN1]_{read,write}... functions and macros now take an
2066 additional void * argument, which is just handed through whenever
2067 the password callback is called.
2068 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
2070 New function SSL_CTX_set_default_passwd_cb_userdata.
2072 Compatibility note: As many C implementations push function arguments
2073 onto the stack in reverse order, the new library version is likely to
2074 interoperate with programs that have been compiled with the old
2075 pem_password_cb definition (PEM_whatever takes some data that
2076 happens to be on the stack as its last argument, and the callback
2077 just ignores this garbage); but there is no guarantee whatsoever that
2080 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
2081 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
2082 problems not only on Windows, but also on some Unix platforms.
2083 To avoid problematic command lines, these definitions are now in an
2084 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
2085 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
2088 *) MIPS III/IV assembler module is reimplemented.
2091 *) More DES library cleanups: remove references to srand/rand and
2092 delete an unused file.
2095 *) Add support for the the free Netwide assembler (NASM) under Win32,
2096 since not many people have MASM (ml) and it can be hard to obtain.
2097 This is currently experimental but it seems to work OK and pass all
2098 the tests. Check out INSTALL.W32 for info.
2101 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
2102 without temporary keys kept an extra copy of the server key,
2103 and connections with temporary keys did not free everything in case
2107 *) New function RSA_check_key and new openssl rsa option -check
2108 for verifying the consistency of RSA keys.
2109 [Ulf Moeller, Bodo Moeller]
2111 *) Various changes to make Win32 compile work:
2112 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
2113 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
2114 comparison" warnings.
2115 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
2118 *) Add a debugging option to PKCS#5 v2 key generation function: when
2119 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
2120 derived keys are printed to stderr.
2123 *) Copy the flags in ASN1_STRING_dup().
2124 [Roman E. Pavlov <pre@mo.msk.ru>]
2126 *) The x509 application mishandled signing requests containing DSA
2127 keys when the signing key was also DSA and the parameters didn't match.
2129 It was supposed to omit the parameters when they matched the signing key:
2130 the verifying software was then supposed to automatically use the CA's
2131 parameters if they were absent from the end user certificate.
2133 Omitting parameters is no longer recommended. The test was also
2134 the wrong way round! This was probably due to unusual behaviour in
2135 EVP_cmp_parameters() which returns 1 if the parameters match.
2136 This meant that parameters were omitted when they *didn't* match and
2137 the certificate was useless. Certificates signed with 'ca' didn't have
2139 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
2141 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
2142 The interface is as follows:
2143 Applications can use
2144 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
2145 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
2146 "off" is now the default.
2147 The library internally uses
2148 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
2149 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
2150 to disable memory-checking temporarily.
2152 Some inconsistent states that previously were possible (and were
2153 even the default) are now avoided.
2155 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
2156 with each memory chunk allocated; this is occasionally more helpful
2157 than just having a counter.
2159 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
2161 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
2165 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
2166 which largely parallels "options", but is for changing API behaviour,
2167 whereas "options" are about protocol behaviour.
2168 Initial "mode" flags are:
2170 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
2171 a single record has been written.
2172 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
2173 retries use the same buffer location.
2174 (But all of the contents must be
2178 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
2181 *) Fix problems with no-hmac etc.
2182 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
2184 *) New functions RSA_get_default_method(), RSA_set_method() and
2185 RSA_get_method(). These allows replacement of RSA_METHODs without having
2186 to mess around with the internals of an RSA structure.
2189 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
2190 Also really enable memory leak checks in openssl.c and in some
2192 [Chad C. Mulligan, Bodo Moeller]
2194 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
2195 up the length of negative integers. This has now been simplified to just
2196 store the length when it is first determined and use it later, rather
2197 than trying to keep track of where data is copied and updating it to
2199 [Steve Henson, reported by Brien Wheeler
2200 <bwheeler@authentica-security.com>]
2202 *) Add a new function PKCS7_signatureVerify. This allows the verification
2203 of a PKCS#7 signature but with the signing certificate passed to the
2204 function itself. This contrasts with PKCS7_dataVerify which assumes the
2205 certificate is present in the PKCS#7 structure. This isn't always the
2206 case: certificates can be omitted from a PKCS#7 structure and be
2207 distributed by "out of band" means (such as a certificate database).
2210 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
2211 function prototypes in pem.h, also change util/mkdef.pl to add the
2212 necessary function names.
2215 *) mk1mf.pl (used by Windows builds) did not properly read the
2216 options set by Configure in the top level Makefile, and Configure
2217 was not even able to write more than one option correctly.
2218 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
2221 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
2222 file to be loaded from a BIO or FILE pointer. The BIO version will
2223 for example allow memory BIOs to contain config info.
2226 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
2227 Whoever hopes to achieve shared-library compatibility across versions
2228 must use this, not the compile-time macro.
2229 (Exercise 0.9.4: Which is the minimum library version required by
2231 Note: All this applies only to multi-threaded programs, others don't
2235 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
2236 through a BIO pair triggered the default case, i.e.
2237 SSLerr(...,SSL_R_UNKNOWN_STATE).
2240 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
2241 can use the SSL library even if none of the specific BIOs is
2245 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
2246 for the encoded length.
2247 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
2249 *) Add initial documentation of the X509V3 functions.
2252 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
2253 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
2254 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
2255 secure PKCS#8 private key format with a high iteration count.
2258 *) Fix determination of Perl interpreter: A perl or perl5
2259 _directory_ in $PATH was also accepted as the interpreter.
2260 [Ralf S. Engelschall]
2262 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
2263 wrong with it but it was very old and did things like calling
2264 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
2268 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
2269 to use the new extension code.
2272 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
2273 with macros. This should make it easier to change their form, add extra
2274 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
2278 *) Add to configuration table a new entry that can specify an alternative
2279 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
2280 according to Mark Crispin <MRC@Panda.COM>.
2284 *) DES CBC did not update the IV. Weird.
2287 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
2288 Changing the behaviour of the former might break existing programs --
2289 where IV updating is needed, des_ncbc_encrypt can be used.
2292 *) When bntest is run from "make test" it drives bc to check its
2293 calculations, as well as internally checking them. If an internal check
2294 fails, it needs to cause bc to give a non-zero result or make test carries
2295 on without noticing the failure. Fixed.
2298 *) DES library cleanups.
2301 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
2302 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
2303 ciphers. NOTE: although the key derivation function has been verified
2304 against some published test vectors it has not been extensively tested
2305 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
2309 *) Instead of "mkdir -p", which is not fully portable, use new
2310 Perl script "util/mkdir-p.pl".
2313 *) Rewrite the way password based encryption (PBE) is handled. It used to
2314 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
2315 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
2316 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
2317 the 'parameter' field of the AlgorithmIdentifier is passed to the
2318 underlying key generation function so it must do its own ASN1 parsing.
2319 This has also changed the EVP_PBE_CipherInit() function which now has a
2320 'parameter' argument instead of literal salt and iteration count values
2321 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
2324 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
2325 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
2326 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
2327 KEY" because this clashed with PKCS#8 unencrypted string. Since this
2328 value was just used as a "magic string" and not used directly its
2329 value doesn't matter.
2332 *) Introduce some semblance of const correctness to BN. Shame C doesn't
2336 *) "linux-sparc64" configuration (ultrapenguin).
2337 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
2338 "linux-sparc" configuration.
2339 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
2341 *) config now generates no-xxx options for missing ciphers.
2344 *) Support the EBCDIC character set (work in progress).
2345 File ebcdic.c not yet included because it has a different license.
2346 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2348 *) Support BS2000/OSD-POSIX.
2349 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2351 *) Make callbacks for key generation use void * instead of char *.
2354 *) Make S/MIME samples compile (not yet tested).
2357 *) Additional typesafe stacks.
2360 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
2364 Changes between 0.9.3 and 0.9.3a [29 May 1999]
2366 *) New configuration variant "sco5-gcc".
2368 *) Updated some demos.
2369 [Sean O Riordain, Wade Scholine]
2371 *) Add missing BIO_free at exit of pkcs12 application.
2374 *) Fix memory leak in conf.c.
2377 *) Updates for Win32 to assembler version of MD5.
2380 *) Set #! path to perl in apps/der_chop to where we found it
2381 instead of using a fixed path.
2384 *) SHA library changes for irix64-mips4-cc.
2387 *) Improvements for VMS support.
2391 Changes between 0.9.2b and 0.9.3 [24 May 1999]
2393 *) Bignum library bug fix. IRIX 6 passes "make test" now!
2394 This also avoids the problems with SC4.2 and unpatched SC5.
2395 [Andy Polyakov <appro@fy.chalmers.se>]
2397 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
2398 These are required because of the typesafe stack would otherwise break
2399 existing code. If old code used a structure member which used to be STACK
2400 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
2401 sk_num or sk_value it would produce an error because the num, data members
2402 are not present in STACK_OF. Now it just produces a warning. sk_set
2403 replaces the old method of assigning a value to sk_value
2404 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
2405 that does this will no longer work (and should use sk_set instead) but
2406 this could be regarded as a "questionable" behaviour anyway.
2409 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
2410 correctly handle encrypted S/MIME data.
2413 *) Change type of various DES function arguments from des_cblock
2414 (which means, in function argument declarations, pointer to char)
2415 to des_cblock * (meaning pointer to array with 8 char elements),
2416 which allows the compiler to do more typechecking; it was like
2417 that back in SSLeay, but with lots of ugly casts.
2419 Introduce new type const_des_cblock.
2422 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
2423 problems: find RecipientInfo structure that matches recipient certificate
2424 and initialise the ASN1 structures properly based on passed cipher.
2427 *) Belatedly make the BN tests actually check the results.
2430 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
2431 to and from BNs: it was completely broken. New compilation option
2432 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
2433 key elements as negative integers.
2436 *) Reorganize and speed up MD5.
2437 [Andy Polyakov <appro@fy.chalmers.se>]
2440 [Richard Levitte <richard@levitte.org>]
2442 *) New option -out to asn1parse to allow the parsed structure to be
2443 output to a file. This is most useful when combined with the -strparse
2444 option to examine the output of things like OCTET STRINGS.
2447 *) Make SSL library a little more fool-proof by not requiring any longer
2448 that SSL_set_{accept,connect}_state be called before
2449 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
2450 in many applications because usually everything *appeared* to work as
2451 intended anyway -- now it really works as intended).
2454 *) Move openssl.cnf out of lib/.
2457 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
2458 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
2459 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
2460 [Ralf S. Engelschall]
2462 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
2463 handle PKCS#7 enveloped data properly.
2464 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
2466 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
2467 copying pointers. The cert_st handling is changed by this in
2468 various ways (and thus what used to be known as ctx->default_cert
2469 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
2470 any longer when s->cert does not give us what we need).
2471 ssl_cert_instantiate becomes obsolete by this change.
2472 As soon as we've got the new code right (possibly it already is?),
2473 we have solved a couple of bugs of the earlier code where s->cert
2474 was used as if it could not have been shared with other SSL structures.
2476 Note that using the SSL API in certain dirty ways now will result
2477 in different behaviour than observed with earlier library versions:
2478 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
2479 does not influence s as it used to.
2481 In order to clean up things more thoroughly, inside SSL_SESSION
2482 we don't use CERT any longer, but a new structure SESS_CERT
2483 that holds per-session data (if available); currently, this is
2484 the peer's certificate chain and, for clients, the server's certificate
2485 and temporary key. CERT holds only those values that can have
2486 meaningful defaults in an SSL_CTX.
2489 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
2490 from the internal representation. Various PKCS#7 fixes: remove some
2491 evil casts and set the enc_dig_alg field properly based on the signing
2495 *) Allow PKCS#12 password to be set from the command line or the
2496 environment. Let 'ca' get its config file name from the environment
2497 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
2501 *) Allow certificate policies extension to use an IA5STRING for the
2502 organization field. This is contrary to the PKIX definition but
2503 VeriSign uses it and IE5 only recognises this form. Document 'x509'
2507 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
2508 without disallowing inline assembler and the like for non-pedantic builds.
2511 *) Support Borland C++ builder.
2512 [Janez Jere <jj@void.si>, modified by Ulf Möller]
2517 *) SHA-1 cleanups and performance enhancements.
2518 [Andy Polyakov <appro@fy.chalmers.se>]
2520 *) Sparc v8plus assembler for the bignum library.
2521 [Andy Polyakov <appro@fy.chalmers.se>]
2523 *) Accept any -xxx and +xxx compiler options in Configure.
2526 *) Update HPUX configuration.
2529 *) Add missing sk_<type>_unshift() function to safestack.h
2530 [Ralf S. Engelschall]
2532 *) New function SSL_CTX_use_certificate_chain_file that sets the
2533 "extra_cert"s in addition to the certificate. (This makes sense
2534 only for "PEM" format files, as chains as a whole are not
2538 *) Support verify_depth from the SSL API.
2539 x509_vfy.c had what can be considered an off-by-one-error:
2540 Its depth (which was not part of the external interface)
2541 was actually counting the number of certificates in a chain;
2542 now it really counts the depth.
2545 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
2546 instead of X509err, which often resulted in confusing error
2547 messages since the error codes are not globally unique
2548 (e.g. an alleged error in ssl3_accept when a certificate
2549 didn't match the private key).
2551 *) New function SSL_CTX_set_session_id_context that allows to set a default
2552 value (so that you don't need SSL_set_session_id_context for each
2553 connection using the SSL_CTX).
2556 *) OAEP decoding bug fix.
2559 *) Support INSTALL_PREFIX for package builders, as proposed by
2563 *) New Configure options "threads" and "no-threads". For systems
2564 where the proper compiler options are known (currently Solaris
2565 and Linux), "threads" is the default.
2568 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
2571 *) Install various scripts to $(OPENSSLDIR)/misc, not to
2572 $(INSTALLTOP)/bin -- they shouldn't clutter directories
2573 such as /usr/local/bin.
2576 *) "make linux-shared" to build shared libraries.
2577 [Niels Poppe <niels@netbox.org>]
2579 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
2582 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
2583 extension adding in x509 utility.
2586 *) Remove NOPROTO sections and error code comments.
2589 *) Partial rewrite of the DEF file generator to now parse the ANSI
2593 *) New Configure options --prefix=DIR and --openssldir=DIR.
2596 *) Complete rewrite of the error code script(s). It is all now handled
2597 by one script at the top level which handles error code gathering,
2598 header rewriting and C source file generation. It should be much better
2599 than the old method: it now uses a modified version of Ulf's parser to
2600 read the ANSI prototypes in all header files (thus the old K&R definitions
2601 aren't needed for error creation any more) and do a better job of
2602 translating function codes into names. The old 'ASN1 error code imbedded
2603 in a comment' is no longer necessary and it doesn't use .err files which
2604 have now been deleted. Also the error code call doesn't have to appear all
2605 on one line (which resulted in some large lines...).
2608 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
2611 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
2612 0 (which usually indicates a closed connection), but continue reading.
2615 *) Fix some race conditions.
2618 *) Add support for CRL distribution points extension. Add Certificate
2619 Policies and CRL distribution points documentation.
2622 *) Move the autogenerated header file parts to crypto/opensslconf.h.
2625 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
2626 8 of keying material. Merlin has also confirmed interop with this fix
2627 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
2628 [Merlin Hughes <merlin@baltimore.ie>]
2630 *) Fix lots of warnings.
2631 [Richard Levitte <levitte@stacken.kth.se>]
2633 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
2634 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
2635 [Richard Levitte <levitte@stacken.kth.se>]
2637 *) Fix problems with sizeof(long) == 8.
2638 [Andy Polyakov <appro@fy.chalmers.se>]
2640 *) Change functions to ANSI C.
2643 *) Fix typos in error codes.
2644 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
2646 *) Remove defunct assembler files from Configure.
2649 *) SPARC v8 assembler BIGNUM implementation.
2650 [Andy Polyakov <appro@fy.chalmers.se>]
2652 *) Support for Certificate Policies extension: both print and set.
2653 Various additions to support the r2i method this uses.
2656 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
2657 return a const string when you are expecting an allocated buffer.
2660 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
2661 types DirectoryString and DisplayText.
2664 *) Add code to allow r2i extensions to access the configuration database,
2665 add an LHASH database driver and add several ctx helper functions.
2668 *) Fix an evil bug in bn_expand2() which caused various BN functions to
2669 fail when they extended the size of a BIGNUM.
2672 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
2673 support typesafe stack.
2676 *) Fix typo in SSL_[gs]et_options().
2677 [Nils Frostberg <nils@medcom.se>]
2679 *) Delete various functions and files that belonged to the (now obsolete)
2680 old X509V3 handling code.
2683 *) New Configure option "rsaref".
2686 *) Don't auto-generate pem.h.
2689 *) Introduce type-safe ASN.1 SETs.
2692 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
2693 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
2695 *) Introduce type-safe STACKs. This will almost certainly break lots of code
2696 that links with OpenSSL (well at least cause lots of warnings), but fear
2697 not: the conversion is trivial, and it eliminates loads of evil casts. A
2698 few STACKed things have been converted already. Feel free to convert more.
2699 In the fullness of time, I'll do away with the STACK type altogether.
2702 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
2703 specified in <certfile> by updating the entry in the index.txt file.
2704 This way one no longer has to edit the index.txt file manually for
2705 revoking a certificate. The -revoke option does the gory details now.
2706 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
2708 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
2709 `-text' option at all and this way the `-noout -text' combination was
2710 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
2711 [Ralf S. Engelschall]
2713 *) Make sure a corresponding plain text error message exists for the
2714 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
2715 verify callback function determined that a certificate was revoked.
2716 [Ralf S. Engelschall]
2718 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
2719 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
2720 all available cipers including rc5, which was forgotten until now.
2721 In order to let the testing shell script know which algorithms
2722 are available, a new (up to now undocumented) command
2723 "openssl list-cipher-commands" is used.
2726 *) Bugfix: s_client occasionally would sleep in select() when
2727 it should have checked SSL_pending() first.
2730 *) New functions DSA_do_sign and DSA_do_verify to provide access to
2731 the raw DSA values prior to ASN.1 encoding.
2734 *) Tweaks to Configure
2735 [Niels Poppe <niels@netbox.org>]
2737 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
2741 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
2744 *) New config option to avoid instructions that are illegal on the 80386.
2745 The default code is faster, but requires at least a 486.
2748 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
2749 SSL2_SERVER_VERSION (not used at all) macros, which are now the
2750 same as SSL2_VERSION anyway.
2753 *) New "-showcerts" option for s_client.
2756 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
2757 application. Various cleanups and fixes.
2760 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
2761 modify error routines to work internally. Add error codes and PBE init
2762 to library startup routines.
2765 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
2766 packing functions to asn1 and evp. Changed function names and error
2767 codes along the way.
2770 *) PKCS12 integration: and so it begins... First of several patches to
2771 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
2772 objects to objects.h
2775 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
2776 and display support for Thawte strong extranet extension.
2779 *) Add LinuxPPC support.
2780 [Jeff Dubrule <igor@pobox.org>]
2782 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
2783 bn_div_words in alpha.s.
2784 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
2786 *) Make sure the RSA OAEP test is skipped under -DRSAref because
2787 OAEP isn't supported when OpenSSL is built with RSAref.
2788 [Ulf Moeller <ulf@fitug.de>]
2790 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
2791 so they no longer are missing under -DNOPROTO.
2792 [Soren S. Jorvang <soren@t.dk>]
2795 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
2797 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
2798 doesn't work when the session is reused. Coming soon!
2801 *) Fix a security hole, that allows sessions to be reused in the wrong
2802 context thus bypassing client cert protection! All software that uses
2803 client certs and session caches in multiple contexts NEEDS PATCHING to
2804 allow session reuse! A fuller solution is in the works.
2805 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
2807 *) Some more source tree cleanups (removed obsolete files
2808 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
2809 permission on "config" script to be executable) and a fix for the INSTALL
2811 [Ulf Moeller <ulf@fitug.de>]
2813 *) Remove some legacy and erroneous uses of malloc, free instead of
2815 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
2817 *) Make rsa_oaep_test return non-zero on error.
2818 [Ulf Moeller <ulf@fitug.de>]
2820 *) Add support for native Solaris shared libraries. Configure
2821 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
2822 if someone would make that last step automatic.
2823 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
2825 *) ctx_size was not built with the right compiler during "make links". Fixed.
2828 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
2829 except NULL ciphers". This means the default cipher list will no longer
2830 enable NULL ciphers. They need to be specifically enabled e.g. with
2831 the string "DEFAULT:eNULL".
2834 *) Fix to RSA private encryption routines: if p < q then it would
2835 occasionally produce an invalid result. This will only happen with
2836 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
2839 *) Be less restrictive and allow also `perl util/perlpath.pl
2840 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
2841 because this way one can also use an interpreter named `perl5' (which is
2842 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
2843 installed as `perl').
2844 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2846 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
2847 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2849 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
2850 advapi32.lib to Win32 build and change the pem test comparision
2851 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
2852 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
2853 and crypto/des/ede_cbcm_enc.c.
2856 *) DES quad checksum was broken on big-endian architectures. Fixed.
2859 *) Comment out two functions in bio.h that aren't implemented. Fix up the
2860 Win32 test batch file so it (might) work again. The Win32 test batch file
2861 is horrible: I feel ill....
2864 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
2865 in e_os.h. Audit of header files to check ANSI and non ANSI
2866 sections: 10 functions were absent from non ANSI section and not exported
2867 from Windows DLLs. Fixed up libeay.num for new functions.
2870 *) Make `openssl version' output lines consistent.
2871 [Ralf S. Engelschall]
2873 *) Fix Win32 symbol export lists for BIO functions: Added
2874 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
2875 to ms/libeay{16,32}.def.
2876 [Ralf S. Engelschall]
2878 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
2879 fine under Unix and passes some trivial tests I've now added. But the
2880 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
2881 added to make sure no one expects that this stuff really works in the
2882 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
2883 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
2885 [Ralf S. Engelschall]
2887 *) Fix the generation of two part addresses in perl.
2888 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
2890 *) Add config entry for Linux on MIPS.
2891 [John Tobey <jtobey@channel1.com>]
2893 *) Make links whenever Configure is run, unless we are on Windoze.
2896 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
2897 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
2901 *) Add a useful kludge to allow package maintainers to specify compiler and
2902 other platforms details on the command line without having to patch the
2903 Configure script everytime: One now can use ``perl Configure
2904 <id>:<details>'', i.e. platform ids are allowed to have details appended
2905 to them (seperated by colons). This is treated as there would be a static
2906 pre-configured entry in Configure's %table under key <id> with value
2907 <details> and ``perl Configure <id>'' is called. So, when you want to
2908 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
2909 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
2910 now, which overrides the FreeBSD-elf entry on-the-fly.
2911 [Ralf S. Engelschall]
2913 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
2916 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
2917 on the `perl Configure ...' command line. This way one can compile
2918 OpenSSL libraries with Position Independent Code (PIC) which is needed
2919 for linking it into DSOs.
2920 [Ralf S. Engelschall]
2922 *) Remarkably, export ciphers were totally broken and no-one had noticed!
2926 *) Cleaned up the LICENSE document: The official contact for any license
2927 questions now is the OpenSSL core team under openssl-core@openssl.org.
2928 And add a paragraph about the dual-license situation to make sure people
2929 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
2930 to the OpenSSL toolkit.
2931 [Ralf S. Engelschall]
2933 *) General source tree makefile cleanups: Made `making xxx in yyy...'
2934 display consistent in the source tree and replaced `/bin/rm' by `rm'.
2935 Additonally cleaned up the `make links' target: Remove unnecessary
2936 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
2937 to speed processing and no longer clutter the display with confusing
2938 stuff. Instead only the actually done links are displayed.
2939 [Ralf S. Engelschall]
2941 *) Permit null encryption ciphersuites, used for authentication only. It used
2942 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
2943 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
2947 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
2948 signed attributes when verifying signatures (this would break them),
2949 the detached data encoding was wrong and public keys obtained using
2950 X509_get_pubkey() weren't freed.
2953 *) Add text documentation for the BUFFER functions. Also added a work around
2954 to a Win95 console bug. This was triggered by the password read stuff: the
2955 last character typed gets carried over to the next fread(). If you were
2956 generating a new cert request using 'req' for example then the last
2957 character of the passphrase would be CR which would then enter the first
2961 *) Added the new `Includes OpenSSL Cryptography Software' button as
2962 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
2963 button and can be used by applications based on OpenSSL to show the
2964 relationship to the OpenSSL project.
2965 [Ralf S. Engelschall]
2967 *) Remove confusing variables in function signatures in files
2968 ssl/ssl_lib.c and ssl/ssl.h.
2969 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2971 *) Don't install bss_file.c under PREFIX/include/
2972 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2974 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
2975 functions that return function pointers and has support for NT specific
2976 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
2977 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
2978 unsigned to signed types: this was killing the Win32 compile.
2981 *) Add new certificate file to stack functions,
2982 SSL_add_dir_cert_subjects_to_stack() and
2983 SSL_add_file_cert_subjects_to_stack(). These largely supplant
2984 SSL_load_client_CA_file(), and can be used to add multiple certs easily
2985 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
2986 This means that Apache-SSL and similar packages don't have to mess around
2987 to add as many CAs as they want to the preferred list.
2990 *) Experiment with doxygen documentation. Currently only partially applied to
2992 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
2993 openssl.doxy as the configuration file.
2996 *) Get rid of remaining C++-style comments which strict C compilers hate.
2997 [Ralf S. Engelschall, pointed out by Carlos Amengual]
2999 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
3000 compiled in by default: it has problems with large keys.
3003 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
3004 DH private keys and/or callback functions which directly correspond to
3005 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
3006 is needed for applications which have to configure certificates on a
3007 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
3009 For the RSA certificate situation is makes no difference, but
3010 for the DSA certificate situation this fixes the "no shared cipher"
3011 problem where the OpenSSL cipher selection procedure failed because the
3012 temporary keys were not overtaken from the context and the API provided
3013 no way to reconfigure them.
3014 The new functions now let applications reconfigure the stuff and they
3015 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
3016 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
3017 non-public-API function ssl_cert_instantiate() is used as a helper
3018 function and also to reduce code redundancy inside ssl_rsa.c.
3019 [Ralf S. Engelschall]
3021 *) Move s_server -dcert and -dkey options out of the undocumented feature
3022 area because they are useful for the DSA situation and should be
3023 recognized by the users.
3024 [Ralf S. Engelschall]
3026 *) Fix the cipher decision scheme for export ciphers: the export bits are
3027 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
3028 SSL_EXP_MASK. So, the original variable has to be used instead of the
3029 already masked variable.
3030 [Richard Levitte <levitte@stacken.kth.se>]
3032 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
3033 [Richard Levitte <levitte@stacken.kth.se>]
3035 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
3036 from `int' to `unsigned int' because it's a length and initialized by
3037 EVP_DigestFinal() which expects an `unsigned int *'.
3038 [Richard Levitte <levitte@stacken.kth.se>]
3040 *) Don't hard-code path to Perl interpreter on shebang line of Configure
3041 script. Instead use the usual Shell->Perl transition trick.
3042 [Ralf S. Engelschall]
3044 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
3045 (in addition to RSA certificates) to match the behaviour of `openssl dsa
3046 -noout -modulus' as it's already the case for `openssl rsa -noout
3047 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
3048 currently the public key is printed (a decision which was already done by
3049 `openssl dsa -modulus' in the past) which serves a similar purpose.
3050 Additionally the NO_RSA no longer completely removes the whole -modulus
3051 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
3053 [Ralf S. Engelschall]
3055 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
3056 BIO. See the source (crypto/evp/bio_ok.c) for more info.
3057 [Arne Ansper <arne@ats.cyber.ee>]
3059 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
3060 to be added. Now both 'req' and 'ca' can use new objects defined in the
3064 *) Add cool BIO that does syslog (or event log on NT).
3065 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
3067 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
3068 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
3069 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
3070 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
3073 *) Add preliminary config info for new extension code.
3076 *) Make RSA_NO_PADDING really use no padding.
3077 [Ulf Moeller <ulf@fitug.de>]
3079 *) Generate errors when private/public key check is done.
3082 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
3083 for some CRL extensions and new objects added.
3086 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
3087 key usage extension and fuller support for authority key id.
3090 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
3091 padding method for RSA, which is recommended for new applications in PKCS
3092 #1 v2.0 (RFC 2437, October 1998).
3093 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
3094 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
3095 against Bleichbacher's attack on RSA.
3096 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
3099 *) Updates to the new SSL compression code
3100 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3102 *) Fix so that the version number in the master secret, when passed
3103 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
3104 (because the server will not accept higher), that the version number
3105 is 0x03,0x01, not 0x03,0x00
3106 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3108 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
3109 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
3110 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
3113 *) Support for RAW extensions where an arbitrary extension can be
3114 created by including its DER encoding. See apps/openssl.cnf for
3118 *) Make sure latest Perl versions don't interpret some generated C array
3119 code as Perl array code in the crypto/err/err_genc.pl script.
3120 [Lars Weber <3weber@informatik.uni-hamburg.de>]
3122 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
3123 not many people have the assembler. Various Win32 compilation fixes and
3124 update to the INSTALL.W32 file with (hopefully) more accurate Win32
3128 *) Modify configure script 'Configure' to automatically create crypto/date.h
3129 file under Win32 and also build pem.h from pem.org. New script
3130 util/mkfiles.pl to create the MINFO file on environments that can't do a
3131 'make files': perl util/mkfiles.pl >MINFO should work.
3134 *) Major rework of DES function declarations, in the pursuit of correctness
3135 and purity. As a result, many evil casts evaporated, and some weirdness,
3136 too. You may find this causes warnings in your code. Zapping your evil
3137 casts will probably fix them. Mostly.
3140 *) Fix for a typo in asn1.h. Bug fix to object creation script
3141 obj_dat.pl. It considered a zero in an object definition to mean
3142 "end of object": none of the objects in objects.h have any zeros
3143 so it wasn't spotted.
3144 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
3146 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
3147 Masking (CBCM). In the absence of test vectors, the best I have been able
3148 to do is check that the decrypt undoes the encrypt, so far. Send me test
3149 vectors if you have them.
3152 *) Correct calculation of key length for export ciphers (too much space was
3153 allocated for null ciphers). This has not been tested!
3156 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
3157 message is now correct (it understands "crypto" and "ssl" on its
3158 command line). There is also now an "update" option. This will update
3159 the util/ssleay.num and util/libeay.num files with any new functions.
3161 perl util/mkdef.pl crypto ssl update
3162 it will update them.
3165 *) Overhauled the Perl interface (perl/*):
3166 - ported BN stuff to OpenSSL's different BN library
3167 - made the perl/ source tree CVS-aware
3168 - renamed the package from SSLeay to OpenSSL (the files still contain
3169 their history because I've copied them in the repository)
3170 - removed obsolete files (the test scripts will be replaced
3171 by better Test::Harness variants in the future)
3172 [Ralf S. Engelschall]
3174 *) First cut for a very conservative source tree cleanup:
3175 1. merge various obsolete readme texts into doc/ssleay.txt
3176 where we collect the old documents and readme texts.
3177 2. remove the first part of files where I'm already sure that we no
3178 longer need them because of three reasons: either they are just temporary
3179 files which were left by Eric or they are preserved original files where
3180 I've verified that the diff is also available in the CVS via "cvs diff
3181 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
3182 the crypto/md/ stuff).
3183 [Ralf S. Engelschall]
3185 *) More extension code. Incomplete support for subject and issuer alt
3186 name, issuer and authority key id. Change the i2v function parameters
3187 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
3188 what that's for :-) Fix to ASN1 macro which messed up
3189 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
3192 *) Preliminary support for ENUMERATED type. This is largely copied from the
3196 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
3197 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3199 *) Make sure `make rehash' target really finds the `openssl' program.
3200 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3202 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
3203 like to hear about it if this slows down other processors.
3206 *) Add CygWin32 platform information to Configure script.
3207 [Alan Batie <batie@aahz.jf.intel.com>]
3209 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
3210 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
3212 *) New program nseq to manipulate netscape certificate sequences
3215 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
3219 *) Fixes to BN code. Previously the default was to define BN_RECURSION
3220 but the BN code had some problems that would cause failures when
3221 doing certificate verification and some other functions.
3222 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3224 *) Add ASN1 and PEM code to support netscape certificate sequences.
3227 *) Add ASN1 and PEM code to support netscape certificate sequences.
3230 *) Add several PKIX and private extended key usage OIDs.
3233 *) Modify the 'ca' program to handle the new extension code. Modify
3234 openssl.cnf for new extension format, add comments.
3237 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
3238 and add a sample to openssl.cnf so req -x509 now adds appropriate
3242 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
3243 error code, add initial support to X509_print() and x509 application.
3246 *) Takes a deep breath and start addding X509 V3 extension support code. Add
3247 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
3248 stuff is currently isolated and isn't even compiled yet.
3251 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
3252 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
3253 Removed the versions check from X509 routines when loading extensions:
3254 this allows certain broken certificates that don't set the version
3255 properly to be processed.
3258 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
3259 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
3260 can still be regenerated with "make depend".
3263 *) Spelling mistake in C version of CAST-128.
3264 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
3266 *) Changes to the error generation code. The perl script err-code.pl
3267 now reads in the old error codes and retains the old numbers, only
3268 adding new ones if necessary. It also only changes the .err files if new
3269 codes are added. The makefiles have been modified to only insert errors
3270 when needed (to avoid needlessly modifying header files). This is done
3271 by only inserting errors if the .err file is newer than the auto generated
3272 C file. To rebuild all the error codes from scratch (the old behaviour)
3273 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
3274 or delete all the .err files.
3277 *) CAST-128 was incorrectly implemented for short keys. The C version has
3278 been fixed, but is untested. The assembler versions are also fixed, but
3279 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
3280 to regenerate it if needed.
3281 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
3282 Hagino <itojun@kame.net>]
3284 *) File was opened incorrectly in randfile.c.
3285 [Ulf Möller <ulf@fitug.de>]
3287 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
3288 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
3289 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
3290 al: it's just almost always a UTCTime. Note this patch adds new error
3291 codes so do a "make errors" if there are problems.
3294 *) Correct Linux 1 recognition in config.
3295 [Ulf Möller <ulf@fitug.de>]
3297 *) Remove pointless MD5 hash when using DSA keys in ca.
3298 [Anonymous <nobody@replay.com>]
3300 *) Generate an error if given an empty string as a cert directory. Also
3301 generate an error if handed NULL (previously returned 0 to indicate an
3302 error, but didn't set one).
3303 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
3305 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
3308 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
3309 parameters. This was causing a warning which killed off the Win32 compile.
3312 *) Remove C++ style comments from crypto/bn/bn_local.h.
3313 [Neil Costigan <neil.costigan@celocom.com>]
3315 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
3316 based on a text string, looking up short and long names and finally
3317 "dot" format. The "dot" format stuff didn't work. Added new function
3318 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
3319 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
3320 OID is not part of the table.
3323 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
3324 X509_LOOKUP_by_alias().
3327 *) Sort openssl functions by name.
3330 *) Get the gendsa program working (hopefully) and add it to app list. Remove
3331 encryption from sample DSA keys (in case anyone is interested the password
3335 *) Make _all_ *_free functions accept a NULL pointer.
3336 [Frans Heymans <fheymans@isaserver.be>]
3338 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
3340 [Anonymous <nobody@replay.com>]
3342 *) s_server should send the CAfile as acceptable CAs, not its own cert.
3343 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3345 *) Don't blow it for numeric -newkey arguments to apps/req.
3346 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3348 *) Temp key "for export" tests were wrong in s3_srvr.c.
3349 [Anonymous <nobody@replay.com>]
3351 *) Add prototype for temp key callback functions
3352 SSL_CTX_set_tmp_{rsa,dh}_callback().
3355 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
3356 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
3359 *) X509_name_add_entry() freed the wrong thing after an error.
3360 [Arne Ansper <arne@ats.cyber.ee>]
3362 *) rsa_eay.c would attempt to free a NULL context.
3363 [Arne Ansper <arne@ats.cyber.ee>]
3365 *) BIO_s_socket() had a broken should_retry() on Windoze.
3366 [Arne Ansper <arne@ats.cyber.ee>]
3368 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
3369 [Arne Ansper <arne@ats.cyber.ee>]
3371 *) Make sure the already existing X509_STORE->depth variable is initialized
3372 in X509_STORE_new(), but document the fact that this variable is still
3373 unused in the certificate verification process.
3374 [Ralf S. Engelschall]
3376 *) Fix the various library and apps files to free up pkeys obtained from
3377 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
3380 *) Fix reference counting in X509_PUBKEY_get(). This makes
3381 demos/maurice/example2.c work, amongst others, probably.
3382 [Steve Henson and Ben Laurie]
3384 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
3385 `openssl' and second, the shortcut symlinks for the `openssl <command>'
3386 are no longer created. This way we have a single and consistent command
3387 line interface `openssl <command>', similar to `cvs <command>'.
3388 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
3390 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
3391 BIT STRING wrapper always have zero unused bits.
3394 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
3397 *) Make the top-level INSTALL documentation easier to understand.
3400 *) Makefiles updated to exit if an error occurs in a sub-directory
3401 make (including if user presses ^C) [Paul Sutton]
3403 *) Make Montgomery context stuff explicit in RSA data structure.
3406 *) Fix build order of pem and err to allow for generated pem.h.
3409 *) Fix renumbering bug in X509_NAME_delete_entry().
3412 *) Enhanced the err-ins.pl script so it makes the error library number
3413 global and can add a library name. This is needed for external ASN1 and
3414 other error libraries.
3417 *) Fixed sk_insert which never worked properly.
3420 *) Fix ASN1 macros so they can handle indefinite length construted
3421 EXPLICIT tags. Some non standard certificates use these: they can now
3425 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
3426 into a single doc/ssleay.txt bundle. This way the information is still
3427 preserved but no longer messes up this directory. Now it's new room for
3428 the new set of documenation files.
3429 [Ralf S. Engelschall]
3431 *) SETs were incorrectly DER encoded. This was a major pain, because they
3432 shared code with SEQUENCEs, which aren't coded the same. This means that
3433 almost everything to do with SETs or SEQUENCEs has either changed name or
3434 number of arguments.
3435 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
3437 *) Fix test data to work with the above.
3440 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
3441 was already fixed by Eric for 0.9.1 it seems.
3442 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
3444 *) Autodetect FreeBSD3.
3447 *) Fix various bugs in Configure. This affects the following platforms:
3451 unixware-2.0-pentium
3455 *) Eliminate generated files from CVS. Reorder tests to regenerate files
3456 before they are needed.
3459 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
3463 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
3465 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
3466 changed SSLeay to OpenSSL in version strings.
3467 [Ralf S. Engelschall]
3469 *) Some fixups to the top-level documents.
3472 *) Fixed the nasty bug where rsaref.h was not found under compile-time
3473 because the symlink to include/ was missing.
3474 [Ralf S. Engelschall]
3476 *) Incorporated the popular no-RSA/DSA-only patches
3477 which allow to compile a RSA-free SSLeay.
3478 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
3480 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
3481 when "ssleay" is still not found.
3482 [Ralf S. Engelschall]
3484 *) Added more platforms to Configure: Cray T3E, HPUX 11,
3485 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
3487 *) Updated the README file.
3488 [Ralf S. Engelschall]
3490 *) Added various .cvsignore files in the CVS repository subdirs
3491 to make a "cvs update" really silent.
3492 [Ralf S. Engelschall]
3494 *) Recompiled the error-definition header files and added
3495 missing symbols to the Win32 linker tables.
3496 [Ralf S. Engelschall]
3498 *) Cleaned up the top-level documents;
3499 o new files: CHANGES and LICENSE
3500 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
3501 o merged COPYRIGHT into LICENSE
3502 o removed obsolete TODO file
3503 o renamed MICROSOFT to INSTALL.W32
3504 [Ralf S. Engelschall]
3506 *) Removed dummy files from the 0.9.1b source tree:
3507 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
3508 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
3509 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
3510 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
3511 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
3512 [Ralf S. Engelschall]
3514 *) Added various platform portability fixes.
3517 *) The Genesis of the OpenSSL rpject:
3518 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
3519 Young and Tim J. Hudson created while they were working for C2Net until
3521 [The OpenSSL Project]
3524 Changes between 0.9.0b and 0.9.1b [not released]
3526 *) Updated a few CA certificates under certs/
3529 *) Changed some BIGNUM api stuff.
3532 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
3533 DGUX x86, Linux Alpha, etc.
3536 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
3537 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
3541 *) Add -strparse option to asn1pars program which parses nested
3543 [Dr Stephen Henson <shenson@bigfoot.com>]
3545 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
3548 *) DSA fix for "ca" program.
3551 *) Added "-genkey" option to "dsaparam" program.
3554 *) Added RIPE MD160 (rmd160) message digest.
3557 *) Added -a (all) option to "ssleay version" command.
3560 *) Added PLATFORM define which is the id given to Configure.
3563 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
3566 *) Extended the ASN.1 parser routines.
3569 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
3572 *) Added a BN_CTX to the BN library.
3575 *) Fixed the weak key values in DES library
3578 *) Changed API in EVP library for cipher aliases.
3581 *) Added support for RC2/64bit cipher.
3584 *) Converted the lhash library to the crypto/mem.c functions.
3587 *) Added more recognized ASN.1 object ids.
3590 *) Added more RSA padding checks for SSL/TLS.
3593 *) Added BIO proxy/filter functionality.
3596 *) Added extra_certs to SSL_CTX which can be used
3597 send extra CA certificates to the client in the CA cert chain sending
3598 process. It can be configured with SSL_CTX_add_extra_chain_cert().
3601 *) Now Fortezza is denied in the authentication phase because
