4 Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
6 *) Reformat the FAQ so the different questions and answers can be divided
7 i sections depending on the subject.
10 *) Have the zlib compression code load ZLIB.DLL dynamically under
14 *) New function BN_mod_sqrt for computing square roots modulo a prime
15 (Tonelli-Shanks algorithm).
16 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
18 *) Store verify_result within SSL_SESSION also for client side to
19 avoid potential security hole. (Re-used sessions on the client side
20 always resulted in verify_result==X509_V_OK, not using the original
21 result of the server certificate verification.)
24 *) Make BN_mod_inverse faster by explicitly handling small quotients
25 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
26 512 bits], about 30% for larger ones [1024 or 2048 bits].)
29 *) Disable ssl2_peek and ssl3_peek (i.e., both implementations
30 of SSL_peek) because they both are completely broken.
31 They will be fixed RSN by adding an additional 'peek' parameter
32 to the internal read functions.
35 *) New function BN_kronecker.
38 *) Fix BN_gcd so that it works on negative inputs; the result is
39 positive unless both parameters are zero.
40 Previously something reasonably close to an infinite loop was
41 possible because numbers could be growing instead of shrinking
42 in the implementation of Euclid's algorithm.
45 *) Fix BN_is_word() and BN_is_one() macros to take into account the
46 sign of the number in question.
48 Fix BN_is_word(a,w) to work correctly for w == 0.
50 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
51 because its test if the absolute value of 'a' equals 'w'.
52 Note that BN_abs_is_word does *not* handle w == 0 reliably;
53 it exists mostly for use in the implementations of BN_is_zero(),
54 BN_is_one(), and BN_is_word().
57 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
58 the method-specific "init()" handler. Also clean up ex_data after
59 calling the method-specific "finish()" handler. Previously, this was
60 happening the other way round.
63 *) New function BN_swap.
66 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
67 the exponentiation functions are more likely to produce reasonable
68 results on negative inputs.
71 *) Change BN_mod_mul so that the result is always non-negative.
72 Previously, it could be negative if one of the factors was negative;
73 I don't think anyone really wanted that behaviour.
76 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
77 (except for exponentation, which stays in crypto/bn/bn_exp.c,
78 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
79 and add new functions:
92 These functions always generate non-negative results.
94 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
95 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
97 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
98 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
100 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
102 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
103 was actually never needed) and in BN_mul(). The removal in BN_mul()
104 required a small change in bn_mul_part_recursive() and the addition
105 of the static functions bn_cmp_part_words(), bn_sub_part_words()
106 and bn_add_part_words() which do the same thing as bn_cmp_words(),
107 bn_sub_words() and bn_add_words() except they take arrays with
111 *) In 'openssl passwd', verify passwords read from the terminal
112 unless the '-salt' option is used (which usually means that
113 verification would just waste user's time since the resulting
114 hash is going to be compared with some given password hash)
115 or the new '-noverify' option is used.
117 This is an incompatible change, but it does not affect
118 non-interactive use of 'openssl passwd' (passwords on the command
119 line, '-stdin' option, '-in ...' option) and thus should not
123 *) Remove all references to RSAref, since there's no more need for it.
126 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
127 The previous value, 12, was not always sufficient for BN_mod_exp().
130 *) Make DSO load along a path given through an environment variable
131 (SHLIB_PATH) with shl_load().
134 *) Constify the ENGINE code as a result of BIGNUM constification.
135 Also constify the RSA code and most things related to it. In a
136 few places, most notable in the depth of the ASN.1 code, ugly
137 casts back to non-const were required (to be solved at a later
141 *) Make it so the openssl application has all engines loaded by default.
144 *) Constify the BIGNUM routines a little more.
147 *) Make sure that shared libraries get the internal name engine with
148 the full version number and not just 0. This should mark the
149 shared libraries as not backward compatible. Of course, this should
150 be changed again when we can guarantee backward binary compatibility.
153 *) Add the following functions:
159 ENGINE_load_builtin_engines()
161 That way, an application can itself choose if external engines that
162 are built-in in OpenSSL shall ever be used or not. The benefit is
163 that applications won't have to be linked with libdl or other dso
164 libraries unless it's really needed.
166 Changed 'openssl engine' to load all engines on demand.
167 Changed the engine header files to avoid the duplication of some
168 declarations (they differed!).
171 *) 'openssl engine' can now list capabilities.
174 *) Better error reporting in 'openssl engine'.
177 *) Never call load_dh_param(NULL) in s_server.
180 *) Add engine application. It can currently list engines by name and
181 identity, and test if they are actually available.
184 *) Add support for shared libraries under Irix.
185 [Albert Chin-A-Young <china@thewrittenword.com>]
187 *) Improve RPM specification file by forcing symbolic linking and making
188 sure the installed documentation is also owned by root.root.
189 [Damien Miller <djm@mindrot.org>]
191 *) Add configuration option to build on Linux on both big-endian and
193 [Ralf Baechle <ralf@uni-koblenz.de>]
195 *) Give the OpenSSL applications more possibilities to make use of
196 keys (public as well as private) handled by engines.
199 *) Add OCSP code that comes from CertCo.
202 *) Add VMS support for the Rijndael code.
205 *) Added untested support for Nuron crypto accelerator.
208 *) Add support for external cryptographic devices. This code was
209 previously distributed separately as the "engine" branch.
210 [Geoff Thorpe, Richard Levitte]
212 *) Rework the filename-translation in the DSO code. It is now possible to
213 have far greater control over how a "name" is turned into a filename
214 depending on the operating environment and any oddities about the
215 different shared library filenames on each system.
218 *) Support threads on FreeBSD-elf in Configure.
221 *) Add the possibility to create shared libraries on HP-UX
224 *) Fix for SHA1 assembly problem with MASM: it produces
225 warnings about corrupt line number information when assembling
226 with debugging information. This is caused by the overlapping
228 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
231 NCONF_get_number() has no error checking at all. As a replacement,
232 NCONF_get_number_e() is defined (_e for "error checking") and is
233 promoted strongly. The old NCONF_get_number is kept around for
234 binary backward compatibility.
235 Make it possible for methods to load from something other than a BIO,
236 by providing a function pointer that is given a name instead of a BIO.
237 For example, this could be used to load configuration data from an
241 *) Fix typo in get_cert_by_subject() in by_dir.c
242 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
244 *) Rework the system to generate shared libraries:
246 - Make note of the expected extension for the shared libraries and
247 if there is a need for symbolic links from for example libcrypto.so.0
248 to libcrypto.so.0.9.7. There is extended info in Configure for
251 - Make as few rebuilds of the shared libraries as possible.
253 - Still avoid linking the OpenSSL programs with the shared libraries.
255 - When installing, install the shared libraries separately from the
259 *) Fix for non blocking accept BIOs. Added new I/O special reason
260 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
261 with non blocking I/O was not possible because no retry code was
262 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
266 *) Added the beginnings of Rijndael support.
269 *) Fix for bug in DirectoryString mask setting. Add support for
270 X509_NAME_print_ex() in 'req' and X509_print_ex() function
271 to allow certificate printing to more controllable, additional
272 'certopt' option to 'x509' to allow new printing options to be
276 *) Clean old EAY MD5 hack from e_os.h.
279 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
281 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
282 and not in SSL_clear because the latter is also used by the
283 accept/connect functions; previously, the settings made by
284 SSL_set_read_ahead would be lost during the handshake.
285 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
287 *) Correct util/mkdef.pl to be selective about disabled algorithms.
288 Previously, it would create entries for disableed algorithms no
292 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
294 *) In ssl23_get_client_hello, generate an error message when faced
295 with an initial SSL 3.0/TLS record that is too small to contain the
296 first two bytes of the ClientHello message, i.e. client_version.
297 (Note that this is a pathologic case that probably has never happened
298 in real life.) The previous approach was to use the version number
299 from the record header as a substitute; but our protocol choice
300 should not depend on that one because it is not authenticated
301 by the Finished messages.
304 *) More robust randomness gathering functions for Windows.
305 [Jeffrey Altman <jaltman@columbia.edu>]
307 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
308 not set then we don't setup the error code for issuer check errors
309 to avoid possibly overwriting other errors which the callback does
310 handle. If an application does set the flag then we assume it knows
311 what it is doing and can handle the new informational codes
315 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
316 a general "ANY" type, as such it should be able to decode anything
317 including tagged types. However it didn't check the class so it would
318 wrongly interpret tagged types in the same way as their universal
319 counterpart and unknown types were just rejected. Changed so that the
320 tagged and unknown types are handled in the same way as a SEQUENCE:
321 that is the encoding is stored intact. There is also a new type
322 "V_ASN1_OTHER" which is used when the class is not universal, in this
323 case we have no idea what the actual type is so we just lump them all
327 *) On VMS, stdout may very well lead to a file that is written to
328 in a record-oriented fashion. That means that every write() will
329 write a separate record, which will be read separately by the
330 programs trying to read from it. This can be very confusing.
332 The solution is to put a BIO filter in the way that will buffer
333 text until a linefeed is reached, and then write everything a
334 line at a time, so every record written will be an actual line,
335 not chunks of lines and not (usually doesn't happen, but I've
336 seen it once) several lines in one record. BIO_f_linebuffer() is
339 Currently, it's a VMS-only method, because that's where it has
340 been tested well enough.
343 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
344 it can return incorrect results.
345 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
346 but it was in 0.9.6-beta[12].)
349 *) Disable the check for content being present when verifying detached
350 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
351 include zero length content when signing messages.
354 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
355 BIO_ctrl (for BIO pairs).
358 *) Add DSO method for VMS.
361 *) Bug fix: Montgomery multiplication could produce results with the
365 *) Add RPM specification openssl.spec and modify it to build three
366 packages. The default package contains applications, application
367 documentation and run-time libraries. The devel package contains
368 include files, static libraries and function documentation. The
369 doc package contains the contents of the doc directory. The original
370 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
373 *) Add a large number of documentation files for many SSL routines.
374 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
376 *) Add a configuration entry for Sony News 4.
377 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
379 *) Don't set the two most significant bits to one when generating a
380 random number < q in the DSA library.
383 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
384 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
385 the underlying transport is blocking) if a handshake took place.
386 (The default behaviour is needed by applications such as s_client
387 and s_server that use select() to determine when to use SSL_read;
388 but for applications that know in advance when to expect data, it
389 just makes things more complicated.)
392 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
396 *) Add a few more EBCDIC conditionals that make `req' and `x509'
397 work better on such systems.
398 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
400 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
401 Update PKCS12_parse() so it copies the friendlyName and the
402 keyid to the certificates aux info.
405 *) Fix bug in PKCS7_verify() which caused an infinite loop
406 if there was more than one signature.
407 [Sven Uszpelkat <su@celocom.de>]
409 *) Major change in util/mkdef.pl to include extra information
410 about each symbol, as well as presentig variables as well
411 as functions. This change means that there's n more need
412 to rebuild the .num files when some algorithms are excluded.
415 *) Allow the verify time to be set by an application,
416 rather than always using the current time.
419 *) Phase 2 verify code reorganisation. The certificate
420 verify code now looks up an issuer certificate by a
421 number of criteria: subject name, authority key id
422 and key usage. It also verifies self signed certificates
423 by the same criteria. The main comparison function is
424 X509_check_issued() which performs these checks.
426 Lot of changes were necessary in order to support this
427 without completely rewriting the lookup code.
429 Authority and subject key identifier are now cached.
431 The LHASH 'certs' is X509_STORE has now been replaced
432 by a STACK_OF(X509_OBJECT). This is mainly because an
433 LHASH can't store or retrieve multiple objects with
436 As a result various functions (which were all internal
437 use only) have changed to handle the new X509_STORE
438 structure. This will break anything that messed round
439 with X509_STORE internally.
441 The functions X509_STORE_add_cert() now checks for an
442 exact match, rather than just subject name.
444 The X509_STORE API doesn't directly support the retrieval
445 of multiple certificates matching a given criteria, however
446 this can be worked round by performing a lookup first
447 (which will fill the cache with candidate certificates)
448 and then examining the cache for matches. This is probably
449 the best we can do without throwing out X509_LOOKUP
450 entirely (maybe later...).
452 The X509_VERIFY_CTX structure has been enhanced considerably.
454 All certificate lookup operations now go via a get_issuer()
455 callback. Although this currently uses an X509_STORE it
456 can be replaced by custom lookups. This is a simple way
457 to bypass the X509_STORE hackery necessary to make this
458 work and makes it possible to use more efficient techniques
459 in future. A very simple version which uses a simple
460 STACK for its trusted certificate store is also provided
461 using X509_STORE_CTX_trusted_stack().
463 The verify_cb() and verify() callbacks now have equivalents
464 in the X509_STORE_CTX structure.
466 X509_STORE_CTX also has a 'flags' field which can be used
467 to customise the verify behaviour.
470 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
471 excludes S/MIME capabilities.
474 *) When a certificate request is read in keep a copy of the
475 original encoding of the signed data and use it when outputing
476 again. Signatures then use the original encoding rather than
477 a decoded, encoded version which may cause problems if the
478 request is improperly encoded.
481 *) For consistency with other BIO_puts implementations, call
482 buffer_write(b, ...) directly in buffer_puts instead of calling
485 In BIO_puts, increment b->num_write as in BIO_write.
486 [Peter.Sylvester@EdelWeb.fr]
488 *) Fix BN_mul_word for the case where the word is 0. (We have to use
489 BN_zero, we may not return a BIGNUM with an array consisting of
493 *) Avoid calling abort() from within the library when problems are
494 detected, except if preprocessor symbols have been defined
495 (such as REF_CHECK, BN_DEBUG etc.).
498 *) New openssl application 'rsautl'. This utility can be
499 used for low level RSA operations. DER public key
500 BIO/fp routines also added.
503 *) New Configure entry and patches for compiling on QNX 4.
504 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
506 *) A demo state-machine implementation was sponsored by
507 Nuron (http://www.nuron.com/) and is now available in
511 *) New options added to the 'dgst' utility for signature
512 generation and verification.
515 *) Unrecognized PKCS#7 content types are now handled via a
516 catch all ASN1_TYPE structure. This allows unsupported
517 types to be stored as a "blob" and an application can
518 encode and decode it manually.
521 *) Fix various signed/unsigned issues to make a_strex.c
523 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
525 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
526 length if passed a buffer. ASN1_INTEGER_to_BN failed
527 if passed a NULL BN and its argument was negative.
528 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
530 *) Modification to PKCS#7 encoding routines to output definite
531 length encoding. Since currently the whole structures are in
532 memory there's not real point in using indefinite length
533 constructed encoding. However if OpenSSL is compiled with
534 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
537 *) Added BIO_vprintf() and BIO_vsnprintf().
540 *) Added more prefixes to parse for in the the strings written
541 through a logging bio, to cover all the levels that are available
542 through syslog. The prefixes are now:
544 PANIC, EMERG, EMR => LOG_EMERG
545 ALERT, ALR => LOG_ALERT
546 CRIT, CRI => LOG_CRIT
547 ERROR, ERR => LOG_ERR
548 WARNING, WARN, WAR => LOG_WARNING
549 NOTICE, NOTE, NOT => LOG_NOTICE
550 INFO, INF => LOG_INFO
551 DEBUG, DBG => LOG_DEBUG
553 and as before, if none of those prefixes are present at the
554 beginning of the string, LOG_ERR is chosen.
556 On Win32, the LOG_* levels are mapped according to this:
558 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
559 LOG_WARNING => EVENTLOG_WARNING_TYPE
560 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
564 *) Made it possible to reconfigure with just the configuration
565 argument "reconf" or "reconfigure". The command line arguments
566 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
567 and are retrieved from there when reconfiguring.
571 [Assar Westerlund <assar@sics.se>, Richard Levitte]
573 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
576 *) The obj_dat.pl script was messing up the sorting of object
577 names. The reason was that it compared the quoted version
578 of strings as a result "OCSP" > "OCSP Signing" because
579 " > SPACE. Changed script to store unquoted versions of
580 names and add quotes on output. It was also omitting some
581 names from the lookup table if they were given a default
582 value (that is if SN is missing it is given the same
583 value as LN and vice versa), these are now added on the
584 grounds that if an object has a name we should be able to
585 look it up. Finally added warning output when duplicate
586 short or long names are found.
589 *) Changes needed for Tandem NSK.
590 [Scott Uroff <scott@xypro.com>]
592 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
593 RSA_padding_check_SSLv23(), special padding was never detected
594 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
595 version rollback attacks was not effective.
597 In s23_clnt.c, don't use special rollback-attack detection padding
598 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
599 client; similarly, in s23_srvr.c, don't do the rollback check if
600 SSL 2.0 is the only protocol enabled in the server.
603 *) Make it possible to get hexdumps of unprintable data with 'openssl
604 asn1parse'. By implication, the functions ASN1_parse_dump() and
605 BIO_dump_indent() are added.
608 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
609 these print out strings and name structures based on various
610 flags including RFC2253 support and proper handling of
611 multibyte characters. Added options to the 'x509' utility
612 to allow the various flags to be set.
615 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
616 Also change the functions X509_cmp_current_time() and
617 X509_gmtime_adj() work with an ASN1_TIME structure,
618 this will enable certificates using GeneralizedTime in validity
622 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
623 negative public key encodings) on by default,
624 NO_NEG_PUBKEY_BUG can be set to disable it.
627 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
628 content octets. An i2c_ASN1_OBJECT is unnecessary because
629 the encoding can be trivially obtained from the structure.
632 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
633 not read locks (CRYPTO_r_[un]lock).
636 *) A first attempt at creating official support for shared
637 libraries through configuration. I've kept it so the
638 default is static libraries only, and the OpenSSL programs
639 are always statically linked for now, but there are
640 preparations for dynamic linking in place.
641 This has been tested on Linux and True64.
644 *) Randomness polling function for Win9x, as described in:
645 Peter Gutmann, Software Generation of Practically Strong
649 *) Fix so PRNG is seeded in req if using an already existing
653 *) New options to smime application. -inform and -outform
654 allow alternative formats for the S/MIME message including
655 PEM and DER. The -content option allows the content to be
656 specified separately. This should allow things like Netscape
657 form signing output easier to verify.
660 *) Fix the ASN1 encoding of tags using the 'long form'.
663 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
664 STRING types. These convert content octets to and from the
665 underlying type. The actual tag and length octets are
666 already assumed to have been read in and checked. These
667 are needed because all other string types have virtually
668 identical handling apart from the tag. By having versions
669 of the ASN1 functions that just operate on content octets
670 IMPLICIT tagging can be handled properly. It also allows
671 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
672 and ASN1_INTEGER are identical apart from the tag.
675 *) Change the handling of OID objects as follows:
677 - New object identifiers are inserted in objects.txt, following
678 the syntax given in objects.README.
679 - objects.pl is used to process obj_mac.num and create a new
681 - obj_dat.pl is used to create a new obj_dat.h, using the data in
684 This is currently kind of a hack, and the perl code in objects.pl
685 isn't very elegant, but it works as I intended. The simplest way
686 to check that it worked correctly is to look in obj_dat.h and
687 check the array nid_objs and make sure the objects haven't moved
688 around (this is important!). Additions are OK, as well as
689 consistent name changes.
692 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
695 *) Addition of the command line parameter '-rand file' to 'openssl req'.
696 The given file adds to whatever has already been seeded into the
697 random pool through the RANDFILE configuration file option or
698 environment variable, or the default random state file.
701 *) mkstack.pl now sorts each macro group into lexical order.
702 Previously the output order depended on the order the files
703 appeared in the directory, resulting in needless rewriting
707 *) Patches to make OpenSSL compile under Win32 again. Mostly
708 work arounds for the VC++ problem that it treats func() as
709 func(void). Also stripped out the parts of mkdef.pl that
710 added extra typesafe functions: these no longer exist.
713 *) Reorganisation of the stack code. The macros are now all
714 collected in safestack.h . Each macro is defined in terms of
715 a "stack macro" of the form SKM_<name>(type, a, b). The
716 DEBUG_SAFESTACK is now handled in terms of function casts,
717 this has the advantage of retaining type safety without the
718 use of additional functions. If DEBUG_SAFESTACK is not defined
719 then the non typesafe macros are used instead. Also modified the
720 mkstack.pl script to handle the new form. Needs testing to see
721 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
722 the default if no major problems. Similar behaviour for ASN1_SET_OF
726 *) When some versions of IIS use the 'NET' form of private key the
727 key derivation algorithm is different. Normally MD5(password) is
728 used as a 128 bit RC4 key. In the modified case
729 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
730 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
731 as the old Netscape_RSA functions except they have an additional
732 'sgckey' parameter which uses the modified algorithm. Also added
733 an -sgckey command line option to the rsa utility. Thanks to
734 Adrian Peck <bertie@ncipher.com> for posting details of the modified
735 algorithm to openssl-dev.
738 *) The evp_local.h macros were using 'c.##kname' which resulted in
739 invalid expansion on some systems (SCO 5.0.5 for example).
740 Corrected to 'c.kname'.
741 [Phillip Porch <root@theporch.com>]
743 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
744 a STACK of email addresses from a certificate or request, these look
745 in the subject name and the subject alternative name extensions and
746 omit any duplicate addresses.
749 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
750 This makes DSA verification about 2 % faster.
753 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
754 (meaning that now 2^5 values will be precomputed, which is only 4 KB
755 plus overhead for 1024 bit moduli).
756 This makes exponentiations about 0.5 % faster for 1024 bit
757 exponents (as measured by "openssl speed rsa2048").
760 *) Rename memory handling macros to avoid conflicts with other
762 Malloc => OPENSSL_malloc
763 Malloc_locked => OPENSSL_malloc_locked
764 Realloc => OPENSSL_realloc
768 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
769 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
773 [John Jarvie <jjarvie@newsguy.com>]
775 *) The type-safe stack code has been rejigged. It is now only compiled
776 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
777 by default all type-specific stack functions are "#define"d back to
778 standard stack functions. This results in more streamlined output
779 but retains the type-safety checking possibilities of the original
783 *) The STACK code has been cleaned up, and certain type declarations
784 that didn't make a lot of sense have been brought in line. This has
785 also involved a cleanup of sorts in safestack.h to more correctly
786 map type-safe stack functions onto their plain stack counterparts.
787 This work has also resulted in a variety of "const"ifications of
788 lots of the code, especially "_cmp" operations which should normally
789 be prototyped with "const" parameters anyway.
792 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
793 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
794 (The PRNG state consists of two parts, the large pool 'state' and 'md',
795 where all of 'md' is used each time the PRNG is used, but 'state'
796 is used only indexed by a cyclic counter. As entropy may not be
797 well distributed from the beginning, 'md' is important as a
798 chaining variable. However, the output function chains only half
799 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
800 all of 'md', and seeding with STATE_SIZE dummy bytes will result
801 in all of 'state' being rewritten, with the new values depending
802 on virtually all of 'md'. This overcomes the 80 bit limitation.)
805 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
806 the handshake is continued after ssl_verify_cert_chain();
807 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
808 can lead to 'unexplainable' connection aborts later.
809 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
811 *) Major EVP API cipher revision.
812 Add hooks for extra EVP features. This allows various cipher
813 parameters to be set in the EVP interface. Support added for variable
814 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
815 setting of RC2 and RC5 parameters.
817 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
820 Remove lots of duplicated code from the EVP library. For example *every*
821 cipher init() function handles the 'iv' in the same way according to the
822 cipher mode. They also all do nothing if the 'key' parameter is NULL and
823 for CFB and OFB modes they zero ctx->num.
825 New functionality allows removal of S/MIME code RC2 hack.
827 Most of the routines have the same form and so can be declared in terms
830 By shifting this to the top level EVP_CipherInit() it can be removed from
831 all individual ciphers. If the cipher wants to handle IVs or keys
832 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
835 Change lots of functions like EVP_EncryptUpdate() to now return a
836 value: although software versions of the algorithms cannot fail
837 any installed hardware versions can.
840 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
841 this option is set, tolerate broken clients that send the negotiated
842 protocol version number instead of the requested protocol version
846 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
847 i.e. non-zero for export ciphersuites, zero otherwise.
848 Previous versions had this flag inverted, inconsistent with
849 rsa_tmp_cb (..._TMP_RSA_CB).
850 [Bodo Moeller; problem reported by Amit Chopra]
852 *) Add missing DSA library text string. Work around for some IIS
853 key files with invalid SEQUENCE encoding.
856 *) Add a document (doc/standards.txt) that list all kinds of standards
857 and so on that are implemented in OpenSSL.
860 *) Enhance c_rehash script. Old version would mishandle certificates
861 with the same subject name hash and wouldn't handle CRLs at all.
862 Added -fingerprint option to crl utility, to support new c_rehash
866 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
869 *) Fix for SSL server purpose checking. Server checking was
870 rejecting certificates which had extended key usage present
871 but no ssl client purpose.
872 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
874 *) Make PKCS#12 code work with no password. The PKCS#12 spec
875 is a little unclear about how a blank password is handled.
876 Since the password in encoded as a BMPString with terminating
877 double NULL a zero length password would end up as just the
878 double NULL. However no password at all is different and is
879 handled differently in the PKCS#12 key generation code. NS
880 treats a blank password as zero length. MSIE treats it as no
881 password on export: but it will try both on import. We now do
882 the same: PKCS12_parse() tries zero length and no password if
883 the password is set to "" or NULL (NULL is now a valid password:
884 it wasn't before) as does the pkcs12 application.
887 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
888 perror when PEM_read_bio_X509_REQ fails, the error message must
889 be obtained from the error queue.
892 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
893 it in ERR_remove_state if appropriate, and change ERR_get_state
894 accordingly to avoid race conditions (this is necessary because
895 thread_hash is no longer constant once set).
898 *) Bugfix for linux-elf makefile.one.
901 *) RSA_get_default_method() will now cause a default
902 RSA_METHOD to be chosen if one doesn't exist already.
903 Previously this was only set during a call to RSA_new()
904 or RSA_new_method(NULL) meaning it was possible for
905 RSA_get_default_method() to return NULL.
908 *) Added native name translation to the existing DSO code
909 that will convert (if the flag to do so is set) filenames
910 that are sufficiently small and have no path information
911 into a canonical native form. Eg. "blah" converted to
912 "libblah.so" or "blah.dll" etc.
915 *) New function ERR_error_string_n(e, buf, len) which is like
916 ERR_error_string(e, buf), but writes at most 'len' bytes
917 including the 0 terminator. For ERR_error_string_n, 'buf'
919 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
921 *) CONF library reworked to become more general. A new CONF
922 configuration file reader "class" is implemented as well as a
923 new functions (NCONF_*, for "New CONF") to handle it. The now
924 old CONF_* functions are still there, but are reimplemented to
925 work in terms of the new functions. Also, a set of functions
926 to handle the internal storage of the configuration data is
927 provided to make it easier to write new configuration file
928 reader "classes" (I can definitely see something reading a
929 configuration file in XML format, for example), called _CONF_*,
930 or "the configuration storage API"...
932 The new configuration file reading functions are:
934 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
935 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
937 NCONF_default, NCONF_WIN32
939 NCONF_dump_fp, NCONF_dump_bio
941 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
942 NCONF_new creates a new CONF object. This works in the same way
943 as other interfaces in OpenSSL, like the BIO interface.
944 NCONF_dump_* dump the internal storage of the configuration file,
945 which is useful for debugging. All other functions take the same
946 arguments as the old CONF_* functions wth the exception of the
947 first that must be a `CONF *' instead of a `LHASH *'.
949 To make it easer to use the new classes with the old CONF_* functions,
950 the function CONF_set_default_method is provided.
953 *) Add '-tls1' option to 'openssl ciphers', which was already
954 mentioned in the documentation but had not been implemented.
955 (This option is not yet really useful because even the additional
956 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
959 *) Initial DSO code added into libcrypto for letting OpenSSL (and
960 OpenSSL-based applications) load shared libraries and bind to
961 them in a portable way.
962 [Geoff Thorpe, with contributions from Richard Levitte]
964 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
966 *) Make sure _lrotl and _lrotr are only used with MSVC.
968 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
969 (the default implementation of RAND_status).
971 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
972 to '-clrext' (= clear extensions), as intended and documented.
973 [Bodo Moeller; inconsistency pointed out by Michael Attili
976 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
977 was larger than the MD block size.
978 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
980 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
981 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
982 using the passed key: if the passed key was a private key the result
983 of X509_print(), for example, would be to print out all the private key
987 *) des_quad_cksum() byte order bug fix.
988 [Ulf Möller, using the problem description in krb4-0.9.7, where
989 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
991 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
993 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
995 *) For easily testing in shell scripts whether some command
996 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
997 returns with exit code 0 iff no command of the given name is available.
998 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
999 the output goes to stdout and nothing is printed to stderr.
1000 Additional arguments are always ignored.
1002 Since for each cipher there is a command of the same name,
1003 the 'no-cipher' compilation switches can be tested this way.
1005 ('openssl no-XXX' is not able to detect pseudo-commands such
1006 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
1009 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
1012 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
1013 is set; it will be thrown away anyway because each handshake creates
1015 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
1016 to parameters -- in previous versions (since OpenSSL 0.9.3) the
1017 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
1018 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
1021 *) New s_client option -ign_eof: EOF at stdin is ignored, and
1022 'Q' and 'R' lose their special meanings (quit/renegotiate).
1023 This is part of what -quiet does; unlike -quiet, -ign_eof
1024 does not suppress any output.
1027 *) Add compatibility options to the purpose and trust code. The
1028 purpose X509_PURPOSE_ANY is "any purpose" which automatically
1029 accepts a certificate or CA, this was the previous behaviour,
1030 with all the associated security issues.
1032 X509_TRUST_COMPAT is the old trust behaviour: only and
1033 automatically trust self signed roots in certificate store. A
1034 new trust setting X509_TRUST_DEFAULT is used to specify that
1035 a purpose has no associated trust setting and it should instead
1036 use the value in the default purpose.
1039 *) Fix the PKCS#8 DSA private key code so it decodes keys again
1040 and fix a memory leak.
1043 *) In util/mkerr.pl (which implements 'make errors'), preserve
1044 reason strings from the previous version of the .c file, as
1045 the default to have only downcase letters (and digits) in
1046 automatically generated reasons codes is not always appropriate.
1049 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
1050 using strerror. Previously, ERR_reason_error_string() returned
1051 library names as reason strings for SYSerr; but SYSerr is a special
1052 case where small numbers are errno values, not library numbers.
1055 *) Add '-dsaparam' option to 'openssl dhparam' application. This
1056 converts DSA parameters into DH parameters. (When creating parameters,
1057 DSA_generate_parameters is used.)
1060 *) Include 'length' (recommended exponent length) in C code generated
1061 by 'openssl dhparam -C'.
1064 *) The second argument to set_label in perlasm was already being used
1065 so couldn't be used as a "file scope" flag. Moved to third argument
1069 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
1070 instead of RAND_bytes for encryption IVs and salts.
1073 *) Include RAND_status() into RAND_METHOD instead of implementing
1074 it only for md_rand.c Otherwise replacing the PRNG by calling
1075 RAND_set_rand_method would be impossible.
1078 *) Don't let DSA_generate_key() enter an infinite loop if the random
1079 number generation fails.
1082 *) New 'rand' application for creating pseudo-random output.
1085 *) Added configuration support for Linux/IA64
1086 [Rolf Haberrecker <rolf@suse.de>]
1088 *) Assembler module support for Mingw32.
1091 *) Shared library support for HPUX (in shlib/).
1092 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
1094 *) Shared library support for Solaris gcc.
1095 [Lutz Behnke <behnke@trustcenter.de>]
1097 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
1099 *) PKCS7_encrypt() was adding text MIME headers twice because they
1100 were added manually and by SMIME_crlf_copy().
1103 *) In bntest.c don't call BN_rand with zero bits argument.
1104 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
1106 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
1107 case was implemented. This caused BN_div_recp() to fail occasionally.
1110 *) Add an optional second argument to the set_label() in the perl
1111 assembly language builder. If this argument exists and is set
1112 to 1 it signals that the assembler should use a symbol whose
1113 scope is the entire file, not just the current function. This
1114 is needed with MASM which uses the format label:: for this scope.
1115 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
1117 *) Change the ASN1 types so they are typedefs by default. Before
1118 almost all types were #define'd to ASN1_STRING which was causing
1119 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
1123 *) Change names of new functions to the new get1/get0 naming
1124 convention: After 'get1', the caller owns a reference count
1125 and has to call ..._free; 'get0' returns a pointer to some
1126 data structure without incrementing reference counters.
1127 (Some of the existing 'get' functions increment a reference
1128 counter, some don't.)
1129 Similarly, 'set1' and 'add1' functions increase reference
1130 counters or duplicate objects.
1133 *) Allow for the possibility of temp RSA key generation failure:
1134 the code used to assume it always worked and crashed on failure.
1137 *) Fix potential buffer overrun problem in BIO_printf().
1138 [Ulf Möller, using public domain code by Patrick Powell; problem
1139 pointed out by David Sacerdote <das33@cornell.edu>]
1141 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
1142 RAND_egd() and RAND_status(). In the command line application,
1143 the EGD socket can be specified like a seed file using RANDFILE
1147 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
1148 Some CAs (e.g. Verisign) distribute certificates in this form.
1151 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
1152 list to exclude them. This means that no special compilation option
1153 is needed to use anonymous DH: it just needs to be included in the
1157 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
1158 EVP_MD_type. The old functionality is available in a new macro called
1159 EVP_MD_md(). Change code that uses it and update docs.
1162 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
1163 where the 'void *' argument is replaced by a function pointer argument.
1164 Previously 'void *' was abused to point to functions, which works on
1165 many platforms, but is not correct. As these functions are usually
1166 called by macros defined in OpenSSL header files, most source code
1167 should work without changes.
1170 *) <openssl/opensslconf.h> (which is created by Configure) now contains
1171 sections with information on -D... compiler switches used for
1172 compiling the library so that applications can see them. To enable
1173 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
1174 must be defined. E.g.,
1175 #define OPENSSL_ALGORITHM_DEFINES
1176 #include <openssl/opensslconf.h>
1177 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
1178 [Richard Levitte, Ulf and Bodo Möller]
1180 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
1184 *) Change the 'other' type in certificate aux info to a STACK_OF
1185 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
1186 the required ASN1 format: arbitrary types determined by an OID.
1189 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
1190 argument to 'req'. This is not because the function is newer or
1191 better than others it just uses the work 'NEW' in the certificate
1192 request header lines. Some software needs this.
1195 *) Reorganise password command line arguments: now passwords can be
1196 obtained from various sources. Delete the PEM_cb function and make
1197 it the default behaviour: i.e. if the callback is NULL and the
1198 usrdata argument is not NULL interpret it as a null terminated pass
1199 phrase. If usrdata and the callback are NULL then the pass phrase
1200 is prompted for as usual.
1203 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
1204 the support is automatically enabled. The resulting binaries will
1205 autodetect the card and use it if present.
1206 [Ben Laurie and Compaq Inc.]
1208 *) Work around for Netscape hang bug. This sends certificate request
1209 and server done in one record. Since this is perfectly legal in the
1210 SSL/TLS protocol it isn't a "bug" option and is on by default. See
1211 the bugs/SSLv3 entry for more info.
1214 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
1217 *) Add -rand argument to smime and pkcs12 applications and read/write
1221 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
1224 *) Add command line password options to the remaining applications.
1227 *) Bug fix for BN_div_recp() for numerators with an even number of
1231 *) More tests in bntest.c, and changed test_bn output.
1234 *) ./config recognizes MacOS X now.
1237 *) Bug fix for BN_div() when the first words of num and divsor are
1238 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
1241 *) Add support for various broken PKCS#8 formats, and command line
1242 options to produce them.
1245 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
1246 get temporary BIGNUMs from a BN_CTX.
1249 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
1253 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
1254 include a #define from the old name to the new. The original intent
1255 was that statically linked binaries could for example just call
1256 SSLeay_add_all_ciphers() to just add ciphers to the table and not
1257 link with digests. This never worked becayse SSLeay_add_all_digests()
1258 and SSLeay_add_all_ciphers() were in the same source file so calling
1259 one would link with the other. They are now in separate source files.
1262 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
1265 *) Use a less unusual form of the Miller-Rabin primality test (it used
1266 a binary algorithm for exponentiation integrated into the Miller-Rabin
1267 loop, our standard modexp algorithms are faster).
1270 *) Support for the EBCDIC character set completed.
1271 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
1273 *) Source code cleanups: use const where appropriate, eliminate casts,
1274 use void * instead of char * in lhash.
1277 *) Bugfix: ssl3_send_server_key_exchange was not restartable
1278 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
1279 this the server could overwrite ephemeral keys that the client
1283 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
1284 using 50 iterations of the Rabin-Miller test.
1286 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
1287 iterations of the Rabin-Miller test as required by the appendix
1288 to FIPS PUB 186[-1]) instead of DSA_is_prime.
1289 As BN_is_prime_fasttest includes trial division, DSA parameter
1290 generation becomes much faster.
1292 This implies a change for the callback functions in DSA_is_prime
1293 and DSA_generate_parameters: The callback function is called once
1294 for each positive witness in the Rabin-Miller test, not just
1295 occasionally in the inner loop; and the parameters to the
1296 callback function now provide an iteration count for the outer
1297 loop rather than for the current invocation of the inner loop.
1298 DSA_generate_parameters additionally can call the callback
1299 function with an 'iteration count' of -1, meaning that a
1300 candidate has passed the trial division test (when q is generated
1301 from an application-provided seed, trial division is skipped).
1304 *) New function BN_is_prime_fasttest that optionally does trial
1305 division before starting the Rabin-Miller test and has
1306 an additional BN_CTX * argument (whereas BN_is_prime always
1307 has to allocate at least one BN_CTX).
1308 'callback(1, -1, cb_arg)' is called when a number has passed the
1309 trial division stage.
1312 *) Fix for bug in CRL encoding. The validity dates weren't being handled
1316 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
1319 *) New function BN_pseudo_rand().
1322 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
1323 bignum version of BN_from_montgomery() with the working code from
1324 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
1328 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
1329 made it impossible to use the same SSL_SESSION data structure in
1330 SSL2 clients in multiple threads.
1333 *) The return value of RAND_load_file() no longer counts bytes obtained
1334 by stat(). RAND_load_file(..., -1) is new and uses the complete file
1335 to seed the PRNG (previously an explicit byte count was required).
1336 [Ulf Möller, Bodo Möller]
1338 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
1339 used (char *) instead of (void *) and had casts all over the place.
1342 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
1345 *) Retain source code compatibility for BN_prime_checks macro:
1346 BN_is_prime(..., BN_prime_checks, ...) now uses
1347 BN_prime_checks_for_size to determine the appropriate number of
1348 Rabin-Miller iterations.
1351 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
1352 DH_CHECK_P_NOT_SAFE_PRIME.
1353 (Check if this is true? OpenPGP calls them "strong".)
1356 *) Merge the functionality of "dh" and "gendh" programs into a new program
1357 "dhparam". The old programs are retained for now but will handle DH keys
1358 (instead of parameters) in future.
1361 *) Make the ciphers, s_server and s_client programs check the return values
1362 when a new cipher list is set.
1365 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
1366 ciphers. Before when the 56bit ciphers were enabled the sorting was
1369 The syntax for the cipher sorting has been extended to support sorting by
1370 cipher-strength (using the strength_bits hard coded in the tables).
1371 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
1373 Fix a bug in the cipher-command parser: when supplying a cipher command
1374 string with an "undefined" symbol (neither command nor alphanumeric
1375 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
1376 an error is flagged.
1378 Due to the strength-sorting extension, the code of the
1379 ssl_create_cipher_list() function was completely rearranged. I hope that
1380 the readability was also increased :-)
1381 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1383 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
1384 for the first serial number and places 2 in the serial number file. This
1385 avoids problems when the root CA is created with serial number zero and
1386 the first user certificate has the same issuer name and serial number
1390 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
1391 the new code. Add documentation for this stuff.
1394 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
1395 X509_*() to X509at_*() on the grounds that they don't handle X509
1396 structures and behave in an analagous way to the X509v3 functions:
1397 they shouldn't be called directly but wrapper functions should be used
1400 So we also now have some wrapper functions that call the X509at functions
1401 when passed certificate requests. (TO DO: similar things can be done with
1402 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
1403 things. Some of these need some d2i or i2d and print functionality
1404 because they handle more complex structures.)
1407 *) Add missing #ifndefs that caused missing symbols when building libssl
1408 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
1409 NO_RSA in ssl/s2*.c.
1410 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
1412 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
1413 has a return value which indicates the quality of the random data
1414 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
1415 error queue. New function RAND_pseudo_bytes() generates output that is
1416 guaranteed to be unique but not unpredictable. RAND_add is like
1417 RAND_seed, but takes an extra argument for an entropy estimate
1418 (RAND_seed always assumes full entropy).
1421 *) Do more iterations of Rabin-Miller probable prime test (specifically,
1422 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
1423 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
1424 in crypto/bn/bn_prime.c for the complete table). This guarantees a
1425 false-positive rate of at most 2^-80 for random input.
1428 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
1431 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
1432 in the 0.9.5 release), this returns the chain
1433 from an X509_CTX structure with a dup of the stack and all
1434 the X509 reference counts upped: so the stack will exist
1435 after X509_CTX_cleanup() has been called. Modify pkcs12.c
1438 Also make SSL_SESSION_print() print out the verify return
1442 *) Add manpage for the pkcs12 command. Also change the default
1443 behaviour so MAC iteration counts are used unless the new
1444 -nomaciter option is used. This improves file security and
1445 only older versions of MSIE (4.0 for example) need it.
1448 *) Honor the no-xxx Configure options when creating .DEF files.
1451 *) Add PKCS#10 attributes to field table: challengePassword,
1452 unstructuredName and unstructuredAddress. These are taken from
1453 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
1454 international characters are used.
1456 More changes to X509_ATTRIBUTE code: allow the setting of types
1457 based on strings. Remove the 'loc' parameter when adding
1458 attributes because these will be a SET OF encoding which is sorted
1462 *) Initial changes to the 'req' utility to allow request generation
1463 automation. This will allow an application to just generate a template
1464 file containing all the field values and have req construct the
1467 Initial support for X509_ATTRIBUTE handling. Stacks of these are
1468 used all over the place including certificate requests and PKCS#7
1469 structures. They are currently handled manually where necessary with
1470 some primitive wrappers for PKCS#7. The new functions behave in a
1471 manner analogous to the X509 extension functions: they allow
1472 attributes to be looked up by NID and added.
1474 Later something similar to the X509V3 code would be desirable to
1475 automatically handle the encoding, decoding and printing of the
1476 more complex types. The string types like challengePassword can
1477 be handled by the string table functions.
1479 Also modified the multi byte string table handling. Now there is
1480 a 'global mask' which masks out certain types. The table itself
1481 can use the flag STABLE_NO_MASK to ignore the mask setting: this
1482 is useful when for example there is only one permissible type
1483 (as in countryName) and using the mask might result in no valid
1487 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
1488 SSL_get_peer_finished to allow applications to obtain the latest
1489 Finished messages sent to the peer or expected from the peer,
1490 respectively. (SSL_get_peer_finished is usually the Finished message
1491 actually received from the peer, otherwise the protocol will be aborted.)
1493 As the Finished message are message digests of the complete handshake
1494 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
1495 be used for external authentication procedures when the authentication
1496 provided by SSL/TLS is not desired or is not enough.
1499 *) Enhanced support for Alpha Linux is added. Now ./config checks if
1500 the host supports BWX extension and if Compaq C is present on the
1501 $PATH. Just exploiting of the BWX extension results in 20-30%
1502 performance kick for some algorithms, e.g. DES and RC4 to mention
1503 a couple. Compaq C in turn generates ~20% faster code for MD5 and
1507 *) Add support for MS "fast SGC". This is arguably a violation of the
1508 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
1509 weak crypto and after checking the certificate is SGC a second one
1510 with strong crypto. MS SGC stops the first handshake after receiving
1511 the server certificate message and sends a second client hello. Since
1512 a server will typically do all the time consuming operations before
1513 expecting any further messages from the client (server key exchange
1514 is the most expensive) there is little difference between the two.
1516 To get OpenSSL to support MS SGC we have to permit a second client
1517 hello message after we have sent server done. In addition we have to
1518 reset the MAC if we do get this second client hello.
1521 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
1522 if a DER encoded private key is RSA or DSA traditional format. Changed
1523 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
1524 format DER encoded private key. Newer code should use PKCS#8 format which
1525 has the key type encoded in the ASN1 structure. Added DER private key
1526 support to pkcs8 application.
1529 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
1530 ciphersuites has been selected (as required by the SSL 3/TLS 1
1531 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
1532 is set, we interpret this as a request to violate the specification
1533 (the worst that can happen is a handshake failure, and 'correct'
1534 behaviour would result in a handshake failure anyway).
1537 *) In SSL_CTX_add_session, take into account that there might be multiple
1538 SSL_SESSION structures with the same session ID (e.g. when two threads
1539 concurrently obtain them from an external cache).
1540 The internal cache can handle only one SSL_SESSION with a given ID,
1541 so if there's a conflict, we now throw out the old one to achieve
1545 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
1546 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
1547 some routines that use cipher OIDs: some ciphers do not have OIDs
1548 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
1552 *) Simplify the trust setting structure and code. Now we just have
1553 two sequences of OIDs for trusted and rejected settings. These will
1554 typically have values the same as the extended key usage extension
1555 and any application specific purposes.
1557 The trust checking code now has a default behaviour: it will just
1558 check for an object with the same NID as the passed id. Functions can
1559 be provided to override either the default behaviour or the behaviour
1560 for a given id. SSL client, server and email already have functions
1561 in place for compatibility: they check the NID and also return "trusted"
1562 if the certificate is self signed.
1565 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
1566 traditional format into an EVP_PKEY structure.
1569 *) Add a password callback function PEM_cb() which either prompts for
1570 a password if usr_data is NULL or otherwise assumes it is a null
1571 terminated password. Allow passwords to be passed on command line
1572 environment or config files in a few more utilities.
1575 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
1576 keys. Add some short names for PKCS#8 PBE algorithms and allow them
1577 to be specified on the command line for the pkcs8 and pkcs12 utilities.
1578 Update documentation.
1581 *) Support for ASN1 "NULL" type. This could be handled before by using
1582 ASN1_TYPE but there wasn't any function that would try to read a NULL
1583 and produce an error if it couldn't. For compatibility we also have
1584 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
1585 don't allocate anything because they don't need to.
1588 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
1590 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
1592 *) Rebuild of the memory allocation routines used by OpenSSL code and
1593 possibly others as well. The purpose is to make an interface that
1594 provide hooks so anyone can build a separate set of allocation and
1595 deallocation routines to be used by OpenSSL, for example memory
1596 pool implementations, or something else, which was previously hard
1597 since Malloc(), Realloc() and Free() were defined as macros having
1598 the values malloc, realloc and free, respectively (except for Win32
1599 compilations). The same is provided for memory debugging code.
1600 OpenSSL already comes with functionality to find memory leaks, but
1601 this gives people a chance to debug other memory problems.
1603 With these changes, a new set of functions and macros have appeared:
1605 CRYPTO_set_mem_debug_functions() [F]
1606 CRYPTO_get_mem_debug_functions() [F]
1607 CRYPTO_dbg_set_options() [F]
1608 CRYPTO_dbg_get_options() [F]
1609 CRYPTO_malloc_debug_init() [M]
1611 The memory debug functions are NULL by default, unless the library
1612 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
1613 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
1614 gives the standard debugging functions that come with OpenSSL) or
1615 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
1616 provided by the library user) must be used. When the standard
1617 debugging functions are used, CRYPTO_dbg_set_options can be used to
1618 request additional information:
1619 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
1620 the CRYPTO_MDEBUG_xxx macro when compiling the library.
1622 Also, things like CRYPTO_set_mem_functions will always give the
1623 expected result (the new set of functions is used for allocation
1624 and deallocation) at all times, regardless of platform and compiler
1627 To finish it up, some functions that were never use in any other
1628 way than through macros have a new API and new semantic:
1631 CRYPTO_dbg_realloc()
1634 All macros of value have retained their old syntax.
1635 [Richard Levitte and Bodo Moeller]
1637 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
1638 ordering of SMIMECapabilities wasn't in "strength order" and there
1639 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
1643 *) Some ASN1 types with illegal zero length encoding (INTEGER,
1644 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
1645 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
1647 *) Merge in my S/MIME library for OpenSSL. This provides a simple
1648 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
1649 functionality to handle multipart/signed properly) and a utility
1650 called 'smime' to call all this stuff. This is based on code I
1651 originally wrote for Celo who have kindly allowed it to be
1652 included in OpenSSL.
1655 *) Add variants des_set_key_checked and des_set_key_unchecked of
1656 des_set_key (aka des_key_sched). Global variable des_check_key
1657 decides which of these is called by des_set_key; this way
1658 des_check_key behaves as it always did, but applications and
1659 the library itself, which was buggy for des_check_key == 1,
1660 have a cleaner way to pick the version they need.
1663 *) New function PKCS12_newpass() which changes the password of a
1667 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
1668 dynamic mix. In both cases the ids can be used as an index into the
1669 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
1670 functions so they accept a list of the field values and the
1671 application doesn't need to directly manipulate the X509_TRUST
1675 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
1679 *) Modify the way the V3 extension code looks up extensions. This now
1680 works in a similar way to the object code: we have some "standard"
1681 extensions in a static table which is searched with OBJ_bsearch()
1682 and the application can add dynamic ones if needed. The file
1683 crypto/x509v3/ext_dat.h now has the info: this file needs to be
1684 updated whenever a new extension is added to the core code and kept
1685 in ext_nid order. There is a simple program 'tabtest.c' which checks
1686 this. New extensions are not added too often so this file can readily
1687 be maintained manually.
1689 There are two big advantages in doing things this way. The extensions
1690 can be looked up immediately and no longer need to be "added" using
1691 X509V3_add_standard_extensions(): this function now does nothing.
1692 [Side note: I get *lots* of email saying the extension code doesn't
1693 work because people forget to call this function]
1694 Also no dynamic allocation is done unless new extensions are added:
1695 so if we don't add custom extensions there is no need to call
1696 X509V3_EXT_cleanup().
1699 *) Modify enc utility's salting as follows: make salting the default. Add a
1700 magic header, so unsalted files fail gracefully instead of just decrypting
1701 to garbage. This is because not salting is a big security hole, so people
1702 should be discouraged from doing it.
1705 *) Fixes and enhancements to the 'x509' utility. It allowed a message
1706 digest to be passed on the command line but it only used this
1707 parameter when signing a certificate. Modified so all relevant
1708 operations are affected by the digest parameter including the
1709 -fingerprint and -x509toreq options. Also -x509toreq choked if a
1710 DSA key was used because it didn't fix the digest.
1713 *) Initial certificate chain verify code. Currently tests the untrusted
1714 certificates for consistency with the verify purpose (which is set
1715 when the X509_STORE_CTX structure is set up) and checks the pathlength.
1717 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
1718 this is because it will reject chains with invalid extensions whereas
1719 every previous version of OpenSSL and SSLeay made no checks at all.
1721 Trust code: checks the root CA for the relevant trust settings. Trust
1722 settings have an initial value consistent with the verify purpose: e.g.
1723 if the verify purpose is for SSL client use it expects the CA to be
1724 trusted for SSL client use. However the default value can be changed to
1725 permit custom trust settings: one example of this would be to only trust
1726 certificates from a specific "secure" set of CAs.
1728 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
1729 which should be used for version portability: especially since the
1730 verify structure is likely to change more often now.
1732 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
1733 to set them. If not set then assume SSL clients will verify SSL servers
1736 Two new options to the verify program: -untrusted allows a set of
1737 untrusted certificates to be passed in and -purpose which sets the
1738 intended purpose of the certificate. If a purpose is set then the
1739 new chain verify code is used to check extension consistency.
1742 *) Support for the authority information access extension.
1745 *) Modify RSA and DSA PEM read routines to transparently handle
1746 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
1747 public keys in a format compatible with certificate
1748 SubjectPublicKeyInfo structures. Unfortunately there were already
1749 functions called *_PublicKey_* which used various odd formats so
1750 these are retained for compatibility: however the DSA variants were
1751 never in a public release so they have been deleted. Changed dsa/rsa
1752 utilities to handle the new format: note no releases ever handled public
1753 keys so we should be OK.
1755 The primary motivation for this change is to avoid the same fiasco
1756 that dogs private keys: there are several incompatible private key
1757 formats some of which are standard and some OpenSSL specific and
1758 require various evil hacks to allow partial transparent handling and
1759 even then it doesn't work with DER formats. Given the option anything
1760 other than PKCS#8 should be dumped: but the other formats have to
1761 stay in the name of compatibility.
1763 With public keys and the benefit of hindsight one standard format
1764 is used which works with EVP_PKEY, RSA or DSA structures: though
1765 it clearly returns an error if you try to read the wrong kind of key.
1767 Added a -pubkey option to the 'x509' utility to output the public key.
1768 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
1769 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
1770 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
1771 that do the same as the EVP_PKEY_assign_*() except they up the
1772 reference count of the added key (they don't "swallow" the
1776 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
1777 CRLs would fail if the file contained no certificates or no CRLs:
1778 added a new function to read in both types and return the number
1779 read: this means that if none are read it will be an error. The
1780 DER versions of the certificate and CRL reader would always fail
1781 because it isn't possible to mix certificates and CRLs in DER format
1782 without choking one or the other routine. Changed this to just read
1783 a certificate: this is the best we can do. Also modified the code
1784 in apps/verify.c to take notice of return codes: it was previously
1785 attempting to read in certificates from NULL pointers and ignoring
1786 any errors: this is one reason why the cert and CRL reader seemed
1787 to work. It doesn't check return codes from the default certificate
1788 routines: these may well fail if the certificates aren't installed.
1791 *) Code to support otherName option in GeneralName.
1794 *) First update to verify code. Change the verify utility
1795 so it warns if it is passed a self signed certificate:
1796 for consistency with the normal behaviour. X509_verify
1797 has been modified to it will now verify a self signed
1798 certificate if *exactly* the same certificate appears
1799 in the store: it was previously impossible to trust a
1800 single self signed certificate. This means that:
1801 openssl verify ss.pem
1802 now gives a warning about a self signed certificate but
1803 openssl verify -CAfile ss.pem ss.pem
1807 *) For servers, store verify_result in SSL_SESSION data structure
1808 (and add it to external session representation).
1809 This is needed when client certificate verifications fails,
1810 but an application-provided verification callback (set by
1811 SSL_CTX_set_cert_verify_callback) allows accepting the session
1812 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
1813 but returns 1): When the session is reused, we have to set
1814 ssl->verify_result to the appropriate error code to avoid
1816 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
1818 *) Fix a bug in the new PKCS#7 code: it didn't consider the
1819 case in PKCS7_dataInit() where the signed PKCS7 structure
1820 didn't contain any existing data because it was being created.
1821 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
1823 *) Add a salt to the key derivation routines in enc.c. This
1824 forms the first 8 bytes of the encrypted file. Also add a
1825 -S option to allow a salt to be input on the command line.
1828 *) New function X509_cmp(). Oddly enough there wasn't a function
1829 to compare two certificates. We do this by working out the SHA1
1830 hash and comparing that. X509_cmp() will be needed by the trust
1834 *) SSL_get1_session() is like SSL_get_session(), but increments
1835 the reference count in the SSL_SESSION returned.
1836 [Geoff Thorpe <geoff@eu.c2.net>]
1838 *) Fix for 'req': it was adding a null to request attributes.
1839 Also change the X509_LOOKUP and X509_INFO code to handle
1840 certificate auxiliary information.
1843 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
1847 *) Add the possibility to add extra information to the memory leak
1848 detecting output, to form tracebacks, showing from where each
1849 allocation was originated: CRYPTO_push_info("constant string") adds
1850 the string plus current file name and line number to a per-thread
1851 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
1852 is like calling CYRPTO_pop_info() until the stack is empty.
1853 Also updated memory leak detection code to be multi-thread-safe.
1856 *) Add options -text and -noout to pkcs7 utility and delete the
1857 encryption options which never did anything. Update docs.
1860 *) Add options to some of the utilities to allow the pass phrase
1861 to be included on either the command line (not recommended on
1862 OSes like Unix) or read from the environment. Update the
1863 manpages and fix a few bugs.
1866 *) Add a few manpages for some of the openssl commands.
1869 *) Fix the -revoke option in ca. It was freeing up memory twice,
1870 leaking and not finding already revoked certificates.
1873 *) Extensive changes to support certificate auxiliary information.
1874 This involves the use of X509_CERT_AUX structure and X509_AUX
1875 functions. An X509_AUX function such as PEM_read_X509_AUX()
1876 can still read in a certificate file in the usual way but it
1877 will also read in any additional "auxiliary information". By
1878 doing things this way a fair degree of compatibility can be
1879 retained: existing certificates can have this information added
1880 using the new 'x509' options.
1882 Current auxiliary information includes an "alias" and some trust
1883 settings. The trust settings will ultimately be used in enhanced
1884 certificate chain verification routines: currently a certificate
1885 can only be trusted if it is self signed and then it is trusted
1889 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
1890 The problem was that one of the replacement routines had not been working
1891 since SSLeay releases. For now the offending routine has been replaced
1892 with non-optimised assembler. Even so, this now gives around 95%
1893 performance improvement for 1024 bit RSA signs.
1896 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
1897 handling. Most clients have the effective key size in bits equal to
1898 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
1899 A few however don't do this and instead use the size of the decrypted key
1900 to determine the RC2 key length and the AlgorithmIdentifier to determine
1901 the effective key length. In this case the effective key length can still
1902 be 40 bits but the key length can be 168 bits for example. This is fixed
1903 by manually forcing an RC2 key into the EVP_PKEY structure because the
1904 EVP code can't currently handle unusual RC2 key sizes: it always assumes
1905 the key length and effective key length are equal.
1908 *) Add a bunch of functions that should simplify the creation of
1909 X509_NAME structures. Now you should be able to do:
1910 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
1911 and have it automatically work out the correct field type and fill in
1912 the structures. The more adventurous can try:
1913 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
1914 and it will (hopefully) work out the correct multibyte encoding.
1917 *) Change the 'req' utility to use the new field handling and multibyte
1918 copy routines. Before the DN field creation was handled in an ad hoc
1919 way in req, ca, and x509 which was rather broken and didn't support
1920 BMPStrings or UTF8Strings. Since some software doesn't implement
1921 BMPStrings or UTF8Strings yet, they can be enabled using the config file
1922 using the dirstring_type option. See the new comment in the default
1923 openssl.cnf for more info.
1926 *) Make crypto/rand/md_rand.c more robust:
1927 - Assure unique random numbers after fork().
1928 - Make sure that concurrent threads access the global counter and
1929 md serializably so that we never lose entropy in them
1930 or use exactly the same state in multiple threads.
1931 Access to the large state is not always serializable because
1932 the additional locking could be a performance killer, and
1933 md should be large enough anyway.
1936 *) New file apps/app_rand.c with commonly needed functionality
1937 for handling the random seed file.
1939 Use the random seed file in some applications that previously did not:
1941 dsaparam -genkey (which also ignored its '-rand' option),
1944 x509 (when signing).
1945 Except on systems with /dev/urandom, it is crucial to have a random
1946 seed file at least for key creation, DSA signing, and for DH exchanges;
1947 for RSA signatures we could do without one.
1949 gendh and gendsa (unlike genrsa) used to read only the first byte
1950 of each file listed in the '-rand' option. The function as previously
1951 found in genrsa is now in app_rand.c and is used by all programs
1952 that support '-rand'.
1955 *) In RAND_write_file, use mode 0600 for creating files;
1956 don't just chmod when it may be too late.
1959 *) Report an error from X509_STORE_load_locations
1960 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
1963 *) New function ASN1_mbstring_copy() this copies a string in either
1964 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
1965 into an ASN1_STRING type. A mask of permissible types is passed
1966 and it chooses the "minimal" type to use or an error if not type
1970 *) Add function equivalents to the various macros in asn1.h. The old
1971 macros are retained with an M_ prefix. Code inside the library can
1972 use the M_ macros. External code (including the openssl utility)
1973 should *NOT* in order to be "shared library friendly".
1976 *) Add various functions that can check a certificate's extensions
1977 to see if it usable for various purposes such as SSL client,
1978 server or S/MIME and CAs of these types. This is currently
1979 VERY EXPERIMENTAL but will ultimately be used for certificate chain
1980 verification. Also added a -purpose flag to x509 utility to
1981 print out all the purposes.
1984 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
1988 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
1989 for, obtain and decode and extension and obtain its critical flag.
1990 This allows all the necessary extension code to be handled in a
1991 single function call.
1994 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
1995 platforms. See crypto/rc4/rc4_enc.c for further details.
1998 *) New -noout option to asn1parse. This causes no output to be produced
1999 its main use is when combined with -strparse and -out to extract data
2000 from a file (which may not be in ASN.1 format).
2003 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
2004 when producing the local key id.
2005 [Richard Levitte <levitte@stacken.kth.se>]
2007 *) New option -dhparam in s_server. This allows a DH parameter file to be
2008 stated explicitly. If it is not stated then it tries the first server
2009 certificate file. The previous behaviour hard coded the filename
2013 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
2014 a public key to be input or output. For example:
2015 openssl rsa -in key.pem -pubout -out pubkey.pem
2016 Also added necessary DSA public key functions to handle this.
2019 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
2020 in the message. This was handled by allowing
2021 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
2022 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
2024 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
2025 to the end of the strings whereas this didn't. This would cause problems
2026 if strings read with d2i_ASN1_bytes() were later modified.
2027 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
2029 *) Fix for base64 decode bug. When a base64 bio reads only one line of
2030 data and it contains EOF it will end up returning an error. This is
2031 caused by input 46 bytes long. The cause is due to the way base64
2032 BIOs find the start of base64 encoded data. They do this by trying a
2033 trial decode on each line until they find one that works. When they
2034 do a flag is set and it starts again knowing it can pass all the
2035 data directly through the decoder. Unfortunately it doesn't reset
2036 the context it uses. This means that if EOF is reached an attempt
2037 is made to pass two EOFs through the context and this causes the
2038 resulting error. This can also cause other problems as well. As is
2039 usual with these problems it takes *ages* to find and the fix is
2040 trivial: move one line.
2041 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
2043 *) Ugly workaround to get s_client and s_server working under Windows. The
2044 old code wouldn't work because it needed to select() on sockets and the
2045 tty (for keypresses and to see if data could be written). Win32 only
2046 supports select() on sockets so we select() with a 1s timeout on the
2047 sockets and then see if any characters are waiting to be read, if none
2048 are present then we retry, we also assume we can always write data to
2049 the tty. This isn't nice because the code then blocks until we've
2050 received a complete line of data and it is effectively polling the
2051 keyboard at 1s intervals: however it's quite a bit better than not
2052 working at all :-) A dedicated Windows application might handle this
2053 with an event loop for example.
2056 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
2057 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
2058 will be called when RSA_sign() and RSA_verify() are used. This is useful
2059 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
2060 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
2061 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
2062 This necessitated the support of an extra signature type NID_md5_sha1
2063 for SSL signatures and modifications to the SSL library to use it instead
2064 of calling RSA_public_decrypt() and RSA_private_encrypt().
2067 *) Add new -verify -CAfile and -CApath options to the crl program, these
2068 will lookup a CRL issuers certificate and verify the signature in a
2069 similar way to the verify program. Tidy up the crl program so it
2070 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
2071 less strict. It will now permit CRL extensions even if it is not
2072 a V2 CRL: this will allow it to tolerate some broken CRLs.
2075 *) Initialize all non-automatic variables each time one of the openssl
2076 sub-programs is started (this is necessary as they may be started
2077 multiple times from the "OpenSSL>" prompt).
2078 [Lennart Bang, Bodo Moeller]
2080 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
2081 removing all other RSA functionality (this is what NO_RSA does). This
2082 is so (for example) those in the US can disable those operations covered
2083 by the RSA patent while allowing storage and parsing of RSA keys and RSA
2087 *) Non-copying interface to BIO pairs.
2088 (still largely untested)
2091 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
2092 ASCII string. This was handled independently in various places before.
2095 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
2096 UTF8 strings a character at a time.
2099 *) Use client_version from client hello to select the protocol
2100 (s23_srvr.c) and for RSA client key exchange verification
2101 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
2104 *) Add various utility functions to handle SPKACs, these were previously
2105 handled by poking round in the structure internals. Added new function
2106 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
2107 print, verify and generate SPKACs. Based on an original idea from
2108 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
2111 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
2114 *) Allow the config file extension section to be overwritten on the
2115 command line. Based on an original idea from Massimiliano Pala
2116 <madwolf@comune.modena.it>. The new option is called -extensions
2117 and can be applied to ca, req and x509. Also -reqexts to override
2118 the request extensions in req and -crlexts to override the crl extensions
2122 *) Add new feature to the SPKAC handling in ca. Now you can include
2123 the same field multiple times by preceding it by "XXXX." for example:
2126 this is the same syntax as used in the req config file.
2129 *) Allow certificate extensions to be added to certificate requests. These
2130 are specified in a 'req_extensions' option of the req section of the
2131 config file. They can be printed out with the -text option to req but
2132 are otherwise ignored at present.
2135 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
2136 data read consists of only the final block it would not decrypted because
2137 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
2138 A misplaced 'break' also meant the decrypted final block might not be
2139 copied until the next read.
2142 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
2143 a few extra parameters to the DH structure: these will be useful if
2144 for example we want the value of 'q' or implement X9.42 DH.
2147 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
2148 provides hooks that allow the default DSA functions or functions on a
2149 "per key" basis to be replaced. This allows hardware acceleration and
2150 hardware key storage to be handled without major modification to the
2151 library. Also added low level modexp hooks and CRYPTO_EX structure and
2152 associated functions.
2155 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
2156 as "read only": it can't be written to and the buffer it points to will
2157 not be freed. Reading from a read only BIO is much more efficient than
2158 a normal memory BIO. This was added because there are several times when
2159 an area of memory needs to be read from a BIO. The previous method was
2160 to create a memory BIO and write the data to it, this results in two
2161 copies of the data and an O(n^2) reading algorithm. There is a new
2162 function BIO_new_mem_buf() which creates a read only memory BIO from
2163 an area of memory. Also modified the PKCS#7 routines to use read only
2167 *) Bugfix: ssl23_get_client_hello did not work properly when called in
2168 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
2169 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
2170 but a retry condition occured while trying to read the rest.
2173 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
2174 NID_pkcs7_encrypted by default: this was wrong since this should almost
2175 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
2176 the encrypted data type: this is a more sensible place to put it and it
2177 allows the PKCS#12 code to be tidied up that duplicated this
2181 *) Changed obj_dat.pl script so it takes its input and output files on
2182 the command line. This should avoid shell escape redirection problems
2186 *) Initial support for certificate extension requests, these are included
2187 in things like Xenroll certificate requests. Included functions to allow
2188 extensions to be obtained and added.
2191 *) -crlf option to s_client and s_server for sending newlines as
2192 CRLF (as required by many protocols).
2195 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
2197 *) Install libRSAglue.a when OpenSSL is built with RSAref.
2198 [Ralf S. Engelschall]
2200 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
2201 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
2203 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
2207 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
2208 DH parameters/keys (q is lost during that conversion, but the resulting
2209 DH parameters contain its length).
2211 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
2212 much faster than DH_generate_parameters (which creates parameters
2213 where p = 2*q + 1), and also the smaller q makes DH computations
2214 much more efficient (160-bit exponentiation instead of 1024-bit
2215 exponentiation); so this provides a convenient way to support DHE
2216 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
2217 utter importance to use
2218 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2220 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2221 when such DH parameters are used, because otherwise small subgroup
2222 attacks may become possible!
2225 *) Avoid memory leak in i2d_DHparams.
2228 *) Allow the -k option to be used more than once in the enc program:
2229 this allows the same encrypted message to be read by multiple recipients.
2232 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
2233 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
2234 it will always use the numerical form of the OID, even if it has a short
2238 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
2239 method only got called if p,q,dmp1,dmq1,iqmp components were present,
2240 otherwise bn_mod_exp was called. In the case of hardware keys for example
2241 no private key components need be present and it might store extra data
2242 in the RSA structure, which cannot be accessed from bn_mod_exp.
2243 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
2244 private key operations.
2247 *) Added support for SPARC Linux.
2250 *) pem_password_cb function type incompatibly changed from
2251 typedef int pem_password_cb(char *buf, int size, int rwflag);
2253 ....(char *buf, int size, int rwflag, void *userdata);
2254 so that applications can pass data to their callbacks:
2255 The PEM[_ASN1]_{read,write}... functions and macros now take an
2256 additional void * argument, which is just handed through whenever
2257 the password callback is called.
2258 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
2260 New function SSL_CTX_set_default_passwd_cb_userdata.
2262 Compatibility note: As many C implementations push function arguments
2263 onto the stack in reverse order, the new library version is likely to
2264 interoperate with programs that have been compiled with the old
2265 pem_password_cb definition (PEM_whatever takes some data that
2266 happens to be on the stack as its last argument, and the callback
2267 just ignores this garbage); but there is no guarantee whatsoever that
2270 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
2271 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
2272 problems not only on Windows, but also on some Unix platforms.
2273 To avoid problematic command lines, these definitions are now in an
2274 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
2275 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
2278 *) MIPS III/IV assembler module is reimplemented.
2281 *) More DES library cleanups: remove references to srand/rand and
2282 delete an unused file.
2285 *) Add support for the the free Netwide assembler (NASM) under Win32,
2286 since not many people have MASM (ml) and it can be hard to obtain.
2287 This is currently experimental but it seems to work OK and pass all
2288 the tests. Check out INSTALL.W32 for info.
2291 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
2292 without temporary keys kept an extra copy of the server key,
2293 and connections with temporary keys did not free everything in case
2297 *) New function RSA_check_key and new openssl rsa option -check
2298 for verifying the consistency of RSA keys.
2299 [Ulf Moeller, Bodo Moeller]
2301 *) Various changes to make Win32 compile work:
2302 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
2303 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
2304 comparison" warnings.
2305 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
2308 *) Add a debugging option to PKCS#5 v2 key generation function: when
2309 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
2310 derived keys are printed to stderr.
2313 *) Copy the flags in ASN1_STRING_dup().
2314 [Roman E. Pavlov <pre@mo.msk.ru>]
2316 *) The x509 application mishandled signing requests containing DSA
2317 keys when the signing key was also DSA and the parameters didn't match.
2319 It was supposed to omit the parameters when they matched the signing key:
2320 the verifying software was then supposed to automatically use the CA's
2321 parameters if they were absent from the end user certificate.
2323 Omitting parameters is no longer recommended. The test was also
2324 the wrong way round! This was probably due to unusual behaviour in
2325 EVP_cmp_parameters() which returns 1 if the parameters match.
2326 This meant that parameters were omitted when they *didn't* match and
2327 the certificate was useless. Certificates signed with 'ca' didn't have
2329 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
2331 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
2332 The interface is as follows:
2333 Applications can use
2334 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
2335 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
2336 "off" is now the default.
2337 The library internally uses
2338 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
2339 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
2340 to disable memory-checking temporarily.
2342 Some inconsistent states that previously were possible (and were
2343 even the default) are now avoided.
2345 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
2346 with each memory chunk allocated; this is occasionally more helpful
2347 than just having a counter.
2349 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
2351 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
2355 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
2356 which largely parallels "options", but is for changing API behaviour,
2357 whereas "options" are about protocol behaviour.
2358 Initial "mode" flags are:
2360 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
2361 a single record has been written.
2362 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
2363 retries use the same buffer location.
2364 (But all of the contents must be
2368 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
2371 *) Fix problems with no-hmac etc.
2372 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
2374 *) New functions RSA_get_default_method(), RSA_set_method() and
2375 RSA_get_method(). These allows replacement of RSA_METHODs without having
2376 to mess around with the internals of an RSA structure.
2379 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
2380 Also really enable memory leak checks in openssl.c and in some
2382 [Chad C. Mulligan, Bodo Moeller]
2384 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
2385 up the length of negative integers. This has now been simplified to just
2386 store the length when it is first determined and use it later, rather
2387 than trying to keep track of where data is copied and updating it to
2389 [Steve Henson, reported by Brien Wheeler
2390 <bwheeler@authentica-security.com>]
2392 *) Add a new function PKCS7_signatureVerify. This allows the verification
2393 of a PKCS#7 signature but with the signing certificate passed to the
2394 function itself. This contrasts with PKCS7_dataVerify which assumes the
2395 certificate is present in the PKCS#7 structure. This isn't always the
2396 case: certificates can be omitted from a PKCS#7 structure and be
2397 distributed by "out of band" means (such as a certificate database).
2400 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
2401 function prototypes in pem.h, also change util/mkdef.pl to add the
2402 necessary function names.
2405 *) mk1mf.pl (used by Windows builds) did not properly read the
2406 options set by Configure in the top level Makefile, and Configure
2407 was not even able to write more than one option correctly.
2408 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
2411 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
2412 file to be loaded from a BIO or FILE pointer. The BIO version will
2413 for example allow memory BIOs to contain config info.
2416 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
2417 Whoever hopes to achieve shared-library compatibility across versions
2418 must use this, not the compile-time macro.
2419 (Exercise 0.9.4: Which is the minimum library version required by
2421 Note: All this applies only to multi-threaded programs, others don't
2425 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
2426 through a BIO pair triggered the default case, i.e.
2427 SSLerr(...,SSL_R_UNKNOWN_STATE).
2430 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
2431 can use the SSL library even if none of the specific BIOs is
2435 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
2436 for the encoded length.
2437 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
2439 *) Add initial documentation of the X509V3 functions.
2442 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
2443 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
2444 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
2445 secure PKCS#8 private key format with a high iteration count.
2448 *) Fix determination of Perl interpreter: A perl or perl5
2449 _directory_ in $PATH was also accepted as the interpreter.
2450 [Ralf S. Engelschall]
2452 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
2453 wrong with it but it was very old and did things like calling
2454 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
2458 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
2459 to use the new extension code.
2462 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
2463 with macros. This should make it easier to change their form, add extra
2464 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
2468 *) Add to configuration table a new entry that can specify an alternative
2469 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
2470 according to Mark Crispin <MRC@Panda.COM>.
2474 *) DES CBC did not update the IV. Weird.
2477 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
2478 Changing the behaviour of the former might break existing programs --
2479 where IV updating is needed, des_ncbc_encrypt can be used.
2482 *) When bntest is run from "make test" it drives bc to check its
2483 calculations, as well as internally checking them. If an internal check
2484 fails, it needs to cause bc to give a non-zero result or make test carries
2485 on without noticing the failure. Fixed.
2488 *) DES library cleanups.
2491 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
2492 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
2493 ciphers. NOTE: although the key derivation function has been verified
2494 against some published test vectors it has not been extensively tested
2495 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
2499 *) Instead of "mkdir -p", which is not fully portable, use new
2500 Perl script "util/mkdir-p.pl".
2503 *) Rewrite the way password based encryption (PBE) is handled. It used to
2504 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
2505 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
2506 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
2507 the 'parameter' field of the AlgorithmIdentifier is passed to the
2508 underlying key generation function so it must do its own ASN1 parsing.
2509 This has also changed the EVP_PBE_CipherInit() function which now has a
2510 'parameter' argument instead of literal salt and iteration count values
2511 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
2514 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
2515 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
2516 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
2517 KEY" because this clashed with PKCS#8 unencrypted string. Since this
2518 value was just used as a "magic string" and not used directly its
2519 value doesn't matter.
2522 *) Introduce some semblance of const correctness to BN. Shame C doesn't
2526 *) "linux-sparc64" configuration (ultrapenguin).
2527 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
2528 "linux-sparc" configuration.
2529 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
2531 *) config now generates no-xxx options for missing ciphers.
2534 *) Support the EBCDIC character set (work in progress).
2535 File ebcdic.c not yet included because it has a different license.
2536 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2538 *) Support BS2000/OSD-POSIX.
2539 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
2541 *) Make callbacks for key generation use void * instead of char *.
2544 *) Make S/MIME samples compile (not yet tested).
2547 *) Additional typesafe stacks.
2550 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
2554 Changes between 0.9.3 and 0.9.3a [29 May 1999]
2556 *) New configuration variant "sco5-gcc".
2558 *) Updated some demos.
2559 [Sean O Riordain, Wade Scholine]
2561 *) Add missing BIO_free at exit of pkcs12 application.
2564 *) Fix memory leak in conf.c.
2567 *) Updates for Win32 to assembler version of MD5.
2570 *) Set #! path to perl in apps/der_chop to where we found it
2571 instead of using a fixed path.
2574 *) SHA library changes for irix64-mips4-cc.
2577 *) Improvements for VMS support.
2581 Changes between 0.9.2b and 0.9.3 [24 May 1999]
2583 *) Bignum library bug fix. IRIX 6 passes "make test" now!
2584 This also avoids the problems with SC4.2 and unpatched SC5.
2585 [Andy Polyakov <appro@fy.chalmers.se>]
2587 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
2588 These are required because of the typesafe stack would otherwise break
2589 existing code. If old code used a structure member which used to be STACK
2590 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
2591 sk_num or sk_value it would produce an error because the num, data members
2592 are not present in STACK_OF. Now it just produces a warning. sk_set
2593 replaces the old method of assigning a value to sk_value
2594 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
2595 that does this will no longer work (and should use sk_set instead) but
2596 this could be regarded as a "questionable" behaviour anyway.
2599 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
2600 correctly handle encrypted S/MIME data.
2603 *) Change type of various DES function arguments from des_cblock
2604 (which means, in function argument declarations, pointer to char)
2605 to des_cblock * (meaning pointer to array with 8 char elements),
2606 which allows the compiler to do more typechecking; it was like
2607 that back in SSLeay, but with lots of ugly casts.
2609 Introduce new type const_des_cblock.
2612 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
2613 problems: find RecipientInfo structure that matches recipient certificate
2614 and initialise the ASN1 structures properly based on passed cipher.
2617 *) Belatedly make the BN tests actually check the results.
2620 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
2621 to and from BNs: it was completely broken. New compilation option
2622 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
2623 key elements as negative integers.
2626 *) Reorganize and speed up MD5.
2627 [Andy Polyakov <appro@fy.chalmers.se>]
2630 [Richard Levitte <richard@levitte.org>]
2632 *) New option -out to asn1parse to allow the parsed structure to be
2633 output to a file. This is most useful when combined with the -strparse
2634 option to examine the output of things like OCTET STRINGS.
2637 *) Make SSL library a little more fool-proof by not requiring any longer
2638 that SSL_set_{accept,connect}_state be called before
2639 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
2640 in many applications because usually everything *appeared* to work as
2641 intended anyway -- now it really works as intended).
2644 *) Move openssl.cnf out of lib/.
2647 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
2648 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
2649 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
2650 [Ralf S. Engelschall]
2652 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
2653 handle PKCS#7 enveloped data properly.
2654 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
2656 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
2657 copying pointers. The cert_st handling is changed by this in
2658 various ways (and thus what used to be known as ctx->default_cert
2659 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
2660 any longer when s->cert does not give us what we need).
2661 ssl_cert_instantiate becomes obsolete by this change.
2662 As soon as we've got the new code right (possibly it already is?),
2663 we have solved a couple of bugs of the earlier code where s->cert
2664 was used as if it could not have been shared with other SSL structures.
2666 Note that using the SSL API in certain dirty ways now will result
2667 in different behaviour than observed with earlier library versions:
2668 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
2669 does not influence s as it used to.
2671 In order to clean up things more thoroughly, inside SSL_SESSION
2672 we don't use CERT any longer, but a new structure SESS_CERT
2673 that holds per-session data (if available); currently, this is
2674 the peer's certificate chain and, for clients, the server's certificate
2675 and temporary key. CERT holds only those values that can have
2676 meaningful defaults in an SSL_CTX.
2679 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
2680 from the internal representation. Various PKCS#7 fixes: remove some
2681 evil casts and set the enc_dig_alg field properly based on the signing
2685 *) Allow PKCS#12 password to be set from the command line or the
2686 environment. Let 'ca' get its config file name from the environment
2687 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
2691 *) Allow certificate policies extension to use an IA5STRING for the
2692 organization field. This is contrary to the PKIX definition but
2693 VeriSign uses it and IE5 only recognises this form. Document 'x509'
2697 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
2698 without disallowing inline assembler and the like for non-pedantic builds.
2701 *) Support Borland C++ builder.
2702 [Janez Jere <jj@void.si>, modified by Ulf Möller]
2707 *) SHA-1 cleanups and performance enhancements.
2708 [Andy Polyakov <appro@fy.chalmers.se>]
2710 *) Sparc v8plus assembler for the bignum library.
2711 [Andy Polyakov <appro@fy.chalmers.se>]
2713 *) Accept any -xxx and +xxx compiler options in Configure.
2716 *) Update HPUX configuration.
2719 *) Add missing sk_<type>_unshift() function to safestack.h
2720 [Ralf S. Engelschall]
2722 *) New function SSL_CTX_use_certificate_chain_file that sets the
2723 "extra_cert"s in addition to the certificate. (This makes sense
2724 only for "PEM" format files, as chains as a whole are not
2728 *) Support verify_depth from the SSL API.
2729 x509_vfy.c had what can be considered an off-by-one-error:
2730 Its depth (which was not part of the external interface)
2731 was actually counting the number of certificates in a chain;
2732 now it really counts the depth.
2735 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
2736 instead of X509err, which often resulted in confusing error
2737 messages since the error codes are not globally unique
2738 (e.g. an alleged error in ssl3_accept when a certificate
2739 didn't match the private key).
2741 *) New function SSL_CTX_set_session_id_context that allows to set a default
2742 value (so that you don't need SSL_set_session_id_context for each
2743 connection using the SSL_CTX).
2746 *) OAEP decoding bug fix.
2749 *) Support INSTALL_PREFIX for package builders, as proposed by
2753 *) New Configure options "threads" and "no-threads". For systems
2754 where the proper compiler options are known (currently Solaris
2755 and Linux), "threads" is the default.
2758 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
2761 *) Install various scripts to $(OPENSSLDIR)/misc, not to
2762 $(INSTALLTOP)/bin -- they shouldn't clutter directories
2763 such as /usr/local/bin.
2766 *) "make linux-shared" to build shared libraries.
2767 [Niels Poppe <niels@netbox.org>]
2769 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
2772 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
2773 extension adding in x509 utility.
2776 *) Remove NOPROTO sections and error code comments.
2779 *) Partial rewrite of the DEF file generator to now parse the ANSI
2783 *) New Configure options --prefix=DIR and --openssldir=DIR.
2786 *) Complete rewrite of the error code script(s). It is all now handled
2787 by one script at the top level which handles error code gathering,
2788 header rewriting and C source file generation. It should be much better
2789 than the old method: it now uses a modified version of Ulf's parser to
2790 read the ANSI prototypes in all header files (thus the old K&R definitions
2791 aren't needed for error creation any more) and do a better job of
2792 translating function codes into names. The old 'ASN1 error code imbedded
2793 in a comment' is no longer necessary and it doesn't use .err files which
2794 have now been deleted. Also the error code call doesn't have to appear all
2795 on one line (which resulted in some large lines...).
2798 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
2801 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
2802 0 (which usually indicates a closed connection), but continue reading.
2805 *) Fix some race conditions.
2808 *) Add support for CRL distribution points extension. Add Certificate
2809 Policies and CRL distribution points documentation.
2812 *) Move the autogenerated header file parts to crypto/opensslconf.h.
2815 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
2816 8 of keying material. Merlin has also confirmed interop with this fix
2817 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
2818 [Merlin Hughes <merlin@baltimore.ie>]
2820 *) Fix lots of warnings.
2821 [Richard Levitte <levitte@stacken.kth.se>]
2823 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
2824 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
2825 [Richard Levitte <levitte@stacken.kth.se>]
2827 *) Fix problems with sizeof(long) == 8.
2828 [Andy Polyakov <appro@fy.chalmers.se>]
2830 *) Change functions to ANSI C.
2833 *) Fix typos in error codes.
2834 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
2836 *) Remove defunct assembler files from Configure.
2839 *) SPARC v8 assembler BIGNUM implementation.
2840 [Andy Polyakov <appro@fy.chalmers.se>]
2842 *) Support for Certificate Policies extension: both print and set.
2843 Various additions to support the r2i method this uses.
2846 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
2847 return a const string when you are expecting an allocated buffer.
2850 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
2851 types DirectoryString and DisplayText.
2854 *) Add code to allow r2i extensions to access the configuration database,
2855 add an LHASH database driver and add several ctx helper functions.
2858 *) Fix an evil bug in bn_expand2() which caused various BN functions to
2859 fail when they extended the size of a BIGNUM.
2862 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
2863 support typesafe stack.
2866 *) Fix typo in SSL_[gs]et_options().
2867 [Nils Frostberg <nils@medcom.se>]
2869 *) Delete various functions and files that belonged to the (now obsolete)
2870 old X509V3 handling code.
2873 *) New Configure option "rsaref".
2876 *) Don't auto-generate pem.h.
2879 *) Introduce type-safe ASN.1 SETs.
2882 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
2883 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
2885 *) Introduce type-safe STACKs. This will almost certainly break lots of code
2886 that links with OpenSSL (well at least cause lots of warnings), but fear
2887 not: the conversion is trivial, and it eliminates loads of evil casts. A
2888 few STACKed things have been converted already. Feel free to convert more.
2889 In the fullness of time, I'll do away with the STACK type altogether.
2892 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
2893 specified in <certfile> by updating the entry in the index.txt file.
2894 This way one no longer has to edit the index.txt file manually for
2895 revoking a certificate. The -revoke option does the gory details now.
2896 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
2898 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
2899 `-text' option at all and this way the `-noout -text' combination was
2900 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
2901 [Ralf S. Engelschall]
2903 *) Make sure a corresponding plain text error message exists for the
2904 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
2905 verify callback function determined that a certificate was revoked.
2906 [Ralf S. Engelschall]
2908 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
2909 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
2910 all available cipers including rc5, which was forgotten until now.
2911 In order to let the testing shell script know which algorithms
2912 are available, a new (up to now undocumented) command
2913 "openssl list-cipher-commands" is used.
2916 *) Bugfix: s_client occasionally would sleep in select() when
2917 it should have checked SSL_pending() first.
2920 *) New functions DSA_do_sign and DSA_do_verify to provide access to
2921 the raw DSA values prior to ASN.1 encoding.
2924 *) Tweaks to Configure
2925 [Niels Poppe <niels@netbox.org>]
2927 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
2931 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
2934 *) New config option to avoid instructions that are illegal on the 80386.
2935 The default code is faster, but requires at least a 486.
2938 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
2939 SSL2_SERVER_VERSION (not used at all) macros, which are now the
2940 same as SSL2_VERSION anyway.
2943 *) New "-showcerts" option for s_client.
2946 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
2947 application. Various cleanups and fixes.
2950 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
2951 modify error routines to work internally. Add error codes and PBE init
2952 to library startup routines.
2955 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
2956 packing functions to asn1 and evp. Changed function names and error
2957 codes along the way.
2960 *) PKCS12 integration: and so it begins... First of several patches to
2961 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
2962 objects to objects.h
2965 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
2966 and display support for Thawte strong extranet extension.
2969 *) Add LinuxPPC support.
2970 [Jeff Dubrule <igor@pobox.org>]
2972 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
2973 bn_div_words in alpha.s.
2974 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
2976 *) Make sure the RSA OAEP test is skipped under -DRSAref because
2977 OAEP isn't supported when OpenSSL is built with RSAref.
2978 [Ulf Moeller <ulf@fitug.de>]
2980 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
2981 so they no longer are missing under -DNOPROTO.
2982 [Soren S. Jorvang <soren@t.dk>]
2985 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
2987 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
2988 doesn't work when the session is reused. Coming soon!
2991 *) Fix a security hole, that allows sessions to be reused in the wrong
2992 context thus bypassing client cert protection! All software that uses
2993 client certs and session caches in multiple contexts NEEDS PATCHING to
2994 allow session reuse! A fuller solution is in the works.
2995 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
2997 *) Some more source tree cleanups (removed obsolete files
2998 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
2999 permission on "config" script to be executable) and a fix for the INSTALL
3001 [Ulf Moeller <ulf@fitug.de>]
3003 *) Remove some legacy and erroneous uses of malloc, free instead of
3005 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
3007 *) Make rsa_oaep_test return non-zero on error.
3008 [Ulf Moeller <ulf@fitug.de>]
3010 *) Add support for native Solaris shared libraries. Configure
3011 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
3012 if someone would make that last step automatic.
3013 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
3015 *) ctx_size was not built with the right compiler during "make links". Fixed.
3018 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
3019 except NULL ciphers". This means the default cipher list will no longer
3020 enable NULL ciphers. They need to be specifically enabled e.g. with
3021 the string "DEFAULT:eNULL".
3024 *) Fix to RSA private encryption routines: if p < q then it would
3025 occasionally produce an invalid result. This will only happen with
3026 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
3029 *) Be less restrictive and allow also `perl util/perlpath.pl
3030 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
3031 because this way one can also use an interpreter named `perl5' (which is
3032 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
3033 installed as `perl').
3034 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3036 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
3037 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3039 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
3040 advapi32.lib to Win32 build and change the pem test comparision
3041 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
3042 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
3043 and crypto/des/ede_cbcm_enc.c.
3046 *) DES quad checksum was broken on big-endian architectures. Fixed.
3049 *) Comment out two functions in bio.h that aren't implemented. Fix up the
3050 Win32 test batch file so it (might) work again. The Win32 test batch file
3051 is horrible: I feel ill....
3054 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
3055 in e_os.h. Audit of header files to check ANSI and non ANSI
3056 sections: 10 functions were absent from non ANSI section and not exported
3057 from Windows DLLs. Fixed up libeay.num for new functions.
3060 *) Make `openssl version' output lines consistent.
3061 [Ralf S. Engelschall]
3063 *) Fix Win32 symbol export lists for BIO functions: Added
3064 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
3065 to ms/libeay{16,32}.def.
3066 [Ralf S. Engelschall]
3068 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
3069 fine under Unix and passes some trivial tests I've now added. But the
3070 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
3071 added to make sure no one expects that this stuff really works in the
3072 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
3073 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
3075 [Ralf S. Engelschall]
3077 *) Fix the generation of two part addresses in perl.
3078 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
3080 *) Add config entry for Linux on MIPS.
3081 [John Tobey <jtobey@channel1.com>]
3083 *) Make links whenever Configure is run, unless we are on Windoze.
3086 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
3087 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
3091 *) Add a useful kludge to allow package maintainers to specify compiler and
3092 other platforms details on the command line without having to patch the
3093 Configure script everytime: One now can use ``perl Configure
3094 <id>:<details>'', i.e. platform ids are allowed to have details appended
3095 to them (seperated by colons). This is treated as there would be a static
3096 pre-configured entry in Configure's %table under key <id> with value
3097 <details> and ``perl Configure <id>'' is called. So, when you want to
3098 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
3099 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
3100 now, which overrides the FreeBSD-elf entry on-the-fly.
3101 [Ralf S. Engelschall]
3103 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
3106 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
3107 on the `perl Configure ...' command line. This way one can compile
3108 OpenSSL libraries with Position Independent Code (PIC) which is needed
3109 for linking it into DSOs.
3110 [Ralf S. Engelschall]
3112 *) Remarkably, export ciphers were totally broken and no-one had noticed!
3116 *) Cleaned up the LICENSE document: The official contact for any license
3117 questions now is the OpenSSL core team under openssl-core@openssl.org.
3118 And add a paragraph about the dual-license situation to make sure people
3119 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
3120 to the OpenSSL toolkit.
3121 [Ralf S. Engelschall]
3123 *) General source tree makefile cleanups: Made `making xxx in yyy...'
3124 display consistent in the source tree and replaced `/bin/rm' by `rm'.
3125 Additonally cleaned up the `make links' target: Remove unnecessary
3126 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
3127 to speed processing and no longer clutter the display with confusing
3128 stuff. Instead only the actually done links are displayed.
3129 [Ralf S. Engelschall]
3131 *) Permit null encryption ciphersuites, used for authentication only. It used
3132 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
3133 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
3137 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
3138 signed attributes when verifying signatures (this would break them),
3139 the detached data encoding was wrong and public keys obtained using
3140 X509_get_pubkey() weren't freed.
3143 *) Add text documentation for the BUFFER functions. Also added a work around
3144 to a Win95 console bug. This was triggered by the password read stuff: the
3145 last character typed gets carried over to the next fread(). If you were
3146 generating a new cert request using 'req' for example then the last
3147 character of the passphrase would be CR which would then enter the first
3151 *) Added the new `Includes OpenSSL Cryptography Software' button as
3152 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
3153 button and can be used by applications based on OpenSSL to show the
3154 relationship to the OpenSSL project.
3155 [Ralf S. Engelschall]
3157 *) Remove confusing variables in function signatures in files
3158 ssl/ssl_lib.c and ssl/ssl.h.
3159 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3161 *) Don't install bss_file.c under PREFIX/include/
3162 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3164 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
3165 functions that return function pointers and has support for NT specific
3166 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
3167 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
3168 unsigned to signed types: this was killing the Win32 compile.
3171 *) Add new certificate file to stack functions,
3172 SSL_add_dir_cert_subjects_to_stack() and
3173 SSL_add_file_cert_subjects_to_stack(). These largely supplant
3174 SSL_load_client_CA_file(), and can be used to add multiple certs easily
3175 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
3176 This means that Apache-SSL and similar packages don't have to mess around
3177 to add as many CAs as they want to the preferred list.
3180 *) Experiment with doxygen documentation. Currently only partially applied to
3182 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
3183 openssl.doxy as the configuration file.
3186 *) Get rid of remaining C++-style comments which strict C compilers hate.
3187 [Ralf S. Engelschall, pointed out by Carlos Amengual]
3189 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
3190 compiled in by default: it has problems with large keys.
3193 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
3194 DH private keys and/or callback functions which directly correspond to
3195 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
3196 is needed for applications which have to configure certificates on a
3197 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
3199 For the RSA certificate situation is makes no difference, but
3200 for the DSA certificate situation this fixes the "no shared cipher"
3201 problem where the OpenSSL cipher selection procedure failed because the
3202 temporary keys were not overtaken from the context and the API provided
3203 no way to reconfigure them.
3204 The new functions now let applications reconfigure the stuff and they
3205 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
3206 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
3207 non-public-API function ssl_cert_instantiate() is used as a helper
3208 function and also to reduce code redundancy inside ssl_rsa.c.
3209 [Ralf S. Engelschall]
3211 *) Move s_server -dcert and -dkey options out of the undocumented feature
3212 area because they are useful for the DSA situation and should be
3213 recognized by the users.
3214 [Ralf S. Engelschall]
3216 *) Fix the cipher decision scheme for export ciphers: the export bits are
3217 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
3218 SSL_EXP_MASK. So, the original variable has to be used instead of the
3219 already masked variable.
3220 [Richard Levitte <levitte@stacken.kth.se>]
3222 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
3223 [Richard Levitte <levitte@stacken.kth.se>]
3225 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
3226 from `int' to `unsigned int' because it's a length and initialized by
3227 EVP_DigestFinal() which expects an `unsigned int *'.
3228 [Richard Levitte <levitte@stacken.kth.se>]
3230 *) Don't hard-code path to Perl interpreter on shebang line of Configure
3231 script. Instead use the usual Shell->Perl transition trick.
3232 [Ralf S. Engelschall]
3234 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
3235 (in addition to RSA certificates) to match the behaviour of `openssl dsa
3236 -noout -modulus' as it's already the case for `openssl rsa -noout
3237 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
3238 currently the public key is printed (a decision which was already done by
3239 `openssl dsa -modulus' in the past) which serves a similar purpose.
3240 Additionally the NO_RSA no longer completely removes the whole -modulus
3241 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
3243 [Ralf S. Engelschall]
3245 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
3246 BIO. See the source (crypto/evp/bio_ok.c) for more info.
3247 [Arne Ansper <arne@ats.cyber.ee>]
3249 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
3250 to be added. Now both 'req' and 'ca' can use new objects defined in the
3254 *) Add cool BIO that does syslog (or event log on NT).
3255 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
3257 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
3258 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
3259 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
3260 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
3263 *) Add preliminary config info for new extension code.
3266 *) Make RSA_NO_PADDING really use no padding.
3267 [Ulf Moeller <ulf@fitug.de>]
3269 *) Generate errors when private/public key check is done.
3272 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
3273 for some CRL extensions and new objects added.
3276 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
3277 key usage extension and fuller support for authority key id.
3280 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
3281 padding method for RSA, which is recommended for new applications in PKCS
3282 #1 v2.0 (RFC 2437, October 1998).
3283 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
3284 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
3285 against Bleichbacher's attack on RSA.
3286 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
3289 *) Updates to the new SSL compression code
3290 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3292 *) Fix so that the version number in the master secret, when passed
3293 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
3294 (because the server will not accept higher), that the version number
3295 is 0x03,0x01, not 0x03,0x00
3296 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3298 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
3299 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
3300 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
3303 *) Support for RAW extensions where an arbitrary extension can be
3304 created by including its DER encoding. See apps/openssl.cnf for
3308 *) Make sure latest Perl versions don't interpret some generated C array
3309 code as Perl array code in the crypto/err/err_genc.pl script.
3310 [Lars Weber <3weber@informatik.uni-hamburg.de>]
3312 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
3313 not many people have the assembler. Various Win32 compilation fixes and
3314 update to the INSTALL.W32 file with (hopefully) more accurate Win32
3318 *) Modify configure script 'Configure' to automatically create crypto/date.h
3319 file under Win32 and also build pem.h from pem.org. New script
3320 util/mkfiles.pl to create the MINFO file on environments that can't do a
3321 'make files': perl util/mkfiles.pl >MINFO should work.
3324 *) Major rework of DES function declarations, in the pursuit of correctness
3325 and purity. As a result, many evil casts evaporated, and some weirdness,
3326 too. You may find this causes warnings in your code. Zapping your evil
3327 casts will probably fix them. Mostly.
3330 *) Fix for a typo in asn1.h. Bug fix to object creation script
3331 obj_dat.pl. It considered a zero in an object definition to mean
3332 "end of object": none of the objects in objects.h have any zeros
3333 so it wasn't spotted.
3334 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
3336 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
3337 Masking (CBCM). In the absence of test vectors, the best I have been able
3338 to do is check that the decrypt undoes the encrypt, so far. Send me test
3339 vectors if you have them.
3342 *) Correct calculation of key length for export ciphers (too much space was
3343 allocated for null ciphers). This has not been tested!
3346 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
3347 message is now correct (it understands "crypto" and "ssl" on its
3348 command line). There is also now an "update" option. This will update
3349 the util/ssleay.num and util/libeay.num files with any new functions.
3351 perl util/mkdef.pl crypto ssl update
3352 it will update them.
3355 *) Overhauled the Perl interface (perl/*):
3356 - ported BN stuff to OpenSSL's different BN library
3357 - made the perl/ source tree CVS-aware
3358 - renamed the package from SSLeay to OpenSSL (the files still contain
3359 their history because I've copied them in the repository)
3360 - removed obsolete files (the test scripts will be replaced
3361 by better Test::Harness variants in the future)
3362 [Ralf S. Engelschall]
3364 *) First cut for a very conservative source tree cleanup:
3365 1. merge various obsolete readme texts into doc/ssleay.txt
3366 where we collect the old documents and readme texts.
3367 2. remove the first part of files where I'm already sure that we no
3368 longer need them because of three reasons: either they are just temporary
3369 files which were left by Eric or they are preserved original files where
3370 I've verified that the diff is also available in the CVS via "cvs diff
3371 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
3372 the crypto/md/ stuff).
3373 [Ralf S. Engelschall]
3375 *) More extension code. Incomplete support for subject and issuer alt
3376 name, issuer and authority key id. Change the i2v function parameters
3377 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
3378 what that's for :-) Fix to ASN1 macro which messed up
3379 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
3382 *) Preliminary support for ENUMERATED type. This is largely copied from the
3386 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
3387 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3389 *) Make sure `make rehash' target really finds the `openssl' program.
3390 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3392 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
3393 like to hear about it if this slows down other processors.
3396 *) Add CygWin32 platform information to Configure script.
3397 [Alan Batie <batie@aahz.jf.intel.com>]
3399 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
3400 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
3402 *) New program nseq to manipulate netscape certificate sequences
3405 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
3409 *) Fixes to BN code. Previously the default was to define BN_RECURSION
3410 but the BN code had some problems that would cause failures when
3411 doing certificate verification and some other functions.
3412 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3414 *) Add ASN1 and PEM code to support netscape certificate sequences.
3417 *) Add ASN1 and PEM code to support netscape certificate sequences.
3420 *) Add several PKIX and private extended key usage OIDs.
3423 *) Modify the 'ca' program to handle the new extension code. Modify
3424 openssl.cnf for new extension format, add comments.
3427 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
3428 and add a sample to openssl.cnf so req -x509 now adds appropriate
3432 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
3433 error code, add initial support to X509_print() and x509 application.
3436 *) Takes a deep breath and start addding X509 V3 extension support code. Add
3437 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
3438 stuff is currently isolated and isn't even compiled yet.
3441 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
3442 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
3443 Removed the versions check from X509 routines when loading extensions:
3444 this allows certain broken certificates that don't set the version
3445 properly to be processed.
3448 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
3449 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
3450 can still be regenerated with "make depend".
3453 *) Spelling mistake in C version of CAST-128.
3454 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
3456 *) Changes to the error generation code. The perl script err-code.pl
3457 now reads in the old error codes and retains the old numbers, only
3458 adding new ones if necessary. It also only changes the .err files if new
3459 codes are added. The makefiles have been modified to only insert errors
3460 when needed (to avoid needlessly modifying header files). This is done
3461 by only inserting errors if the .err file is newer than the auto generated
3462 C file. To rebuild all the error codes from scratch (the old behaviour)
3463 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
3464 or delete all the .err files.
3467 *) CAST-128 was incorrectly implemented for short keys. The C version has
3468 been fixed, but is untested. The assembler versions are also fixed, but
3469 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
3470 to regenerate it if needed.
3471 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
3472 Hagino <itojun@kame.net>]
3474 *) File was opened incorrectly in randfile.c.
3475 [Ulf Möller <ulf@fitug.de>]
3477 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
3478 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
3479 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
3480 al: it's just almost always a UTCTime. Note this patch adds new error
3481 codes so do a "make errors" if there are problems.
3484 *) Correct Linux 1 recognition in config.
3485 [Ulf Möller <ulf@fitug.de>]
3487 *) Remove pointless MD5 hash when using DSA keys in ca.
3488 [Anonymous <nobody@replay.com>]
3490 *) Generate an error if given an empty string as a cert directory. Also
3491 generate an error if handed NULL (previously returned 0 to indicate an
3492 error, but didn't set one).
3493 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
3495 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
3498 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
3499 parameters. This was causing a warning which killed off the Win32 compile.
3502 *) Remove C++ style comments from crypto/bn/bn_local.h.
3503 [Neil Costigan <neil.costigan@celocom.com>]
3505 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
3506 based on a text string, looking up short and long names and finally
3507 "dot" format. The "dot" format stuff didn't work. Added new function
3508 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
3509 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
3510 OID is not part of the table.
3513 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
3514 X509_LOOKUP_by_alias().
3517 *) Sort openssl functions by name.
3520 *) Get the gendsa program working (hopefully) and add it to app list. Remove
3521 encryption from sample DSA keys (in case anyone is interested the password
3525 *) Make _all_ *_free functions accept a NULL pointer.
3526 [Frans Heymans <fheymans@isaserver.be>]
3528 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
3530 [Anonymous <nobody@replay.com>]
3532 *) s_server should send the CAfile as acceptable CAs, not its own cert.
3533 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3535 *) Don't blow it for numeric -newkey arguments to apps/req.
3536 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
3538 *) Temp key "for export" tests were wrong in s3_srvr.c.
3539 [Anonymous <nobody@replay.com>]
3541 *) Add prototype for temp key callback functions
3542 SSL_CTX_set_tmp_{rsa,dh}_callback().
3545 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
3546 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
3549 *) X509_name_add_entry() freed the wrong thing after an error.
3550 [Arne Ansper <arne@ats.cyber.ee>]
3552 *) rsa_eay.c would attempt to free a NULL context.
3553 [Arne Ansper <arne@ats.cyber.ee>]
3555 *) BIO_s_socket() had a broken should_retry() on Windoze.
3556 [Arne Ansper <arne@ats.cyber.ee>]
3558 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
3559 [Arne Ansper <arne@ats.cyber.ee>]
3561 *) Make sure the already existing X509_STORE->depth variable is initialized
3562 in X509_STORE_new(), but document the fact that this variable is still
3563 unused in the certificate verification process.
3564 [Ralf S. Engelschall]
3566 *) Fix the various library and apps files to free up pkeys obtained from
3567 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
3570 *) Fix reference counting in X509_PUBKEY_get(). This makes
3571 demos/maurice/example2.c work, amongst others, probably.
3572 [Steve Henson and Ben Laurie]
3574 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
3575 `openssl' and second, the shortcut symlinks for the `openssl <command>'
3576 are no longer created. This way we have a single and consistent command
3577 line interface `openssl <command>', similar to `cvs <command>'.
3578 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
3580 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
3581 BIT STRING wrapper always have zero unused bits.
3584 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
3587 *) Make the top-level INSTALL documentation easier to understand.
3590 *) Makefiles updated to exit if an error occurs in a sub-directory
3591 make (including if user presses ^C) [Paul Sutton]
3593 *) Make Montgomery context stuff explicit in RSA data structure.
3596 *) Fix build order of pem and err to allow for generated pem.h.
3599 *) Fix renumbering bug in X509_NAME_delete_entry().
3602 *) Enhanced the err-ins.pl script so it makes the error library number
3603 global and can add a library name. This is needed for external ASN1 and
3604 other error libraries.
3607 *) Fixed sk_insert which never worked properly.
3610 *) Fix ASN1 macros so they can handle indefinite length construted
3611 EXPLICIT tags. Some non standard certificates use these: they can now
3615 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
3616 into a single doc/ssleay.txt bundle. This way the information is still
3617 preserved but no longer messes up this directory. Now it's new room for
3618 the new set of documenation files.
3619 [Ralf S. Engelschall]
3621 *) SETs were incorrectly DER encoded. This was a major pain, because they
3622 shared code with SEQUENCEs, which aren't coded the same. This means that
3623 almost everything to do with SETs or SEQUENCEs has either changed name or
3624 number of arguments.
3625 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
3627 *) Fix test data to work with the above.
3630 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
3631 was already fixed by Eric for 0.9.1 it seems.
3632 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
3634 *) Autodetect FreeBSD3.
3637 *) Fix various bugs in Configure. This affects the following platforms:
3641 unixware-2.0-pentium
3645 *) Eliminate generated files from CVS. Reorder tests to regenerate files
3646 before they are needed.
3649 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
3653 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
3655 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
3656 changed SSLeay to OpenSSL in version strings.
3657 [Ralf S. Engelschall]
3659 *) Some fixups to the top-level documents.
3662 *) Fixed the nasty bug where rsaref.h was not found under compile-time
3663 because the symlink to include/ was missing.
3664 [Ralf S. Engelschall]
3666 *) Incorporated the popular no-RSA/DSA-only patches
3667 which allow to compile a RSA-free SSLeay.
3668 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
3670 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
3671 when "ssleay" is still not found.
3672 [Ralf S. Engelschall]
3674 *) Added more platforms to Configure: Cray T3E, HPUX 11,
3675 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
3677 *) Updated the README file.
3678 [Ralf S. Engelschall]
3680 *) Added various .cvsignore files in the CVS repository subdirs
3681 to make a "cvs update" really silent.
3682 [Ralf S. Engelschall]
3684 *) Recompiled the error-definition header files and added
3685 missing symbols to the Win32 linker tables.
3686 [Ralf S. Engelschall]
3688 *) Cleaned up the top-level documents;
3689 o new files: CHANGES and LICENSE
3690 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
3691 o merged COPYRIGHT into LICENSE
3692 o removed obsolete TODO file
3693 o renamed MICROSOFT to INSTALL.W32
3694 [Ralf S. Engelschall]
3696 *) Removed dummy files from the 0.9.1b source tree:
3697 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
3698 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
3699 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
3700 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
3701 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
3702 [Ralf S. Engelschall]
3704 *) Added various platform portability fixes.
3707 *) The Genesis of the OpenSSL rpject:
3708 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
3709 Young and Tim J. Hudson created while they were working for C2Net until
3711 [The OpenSSL Project]
3714 Changes between 0.9.0b and 0.9.1b [not released]
3716 *) Updated a few CA certificates under certs/
3719 *) Changed some BIGNUM api stuff.
3722 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
3723 DGUX x86, Linux Alpha, etc.
3726 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
3727 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
3731 *) Add -strparse option to asn1pars program which parses nested
3733 [Dr Stephen Henson <shenson@bigfoot.com>]
3735 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
3738 *) DSA fix for "ca" program.
3741 *) Added "-genkey" option to "dsaparam" program.
3744 *) Added RIPE MD160 (rmd160) message digest.
3747 *) Added -a (all) option to "ssleay version" command.
3750 *) Added PLATFORM define which is the id given to Configure.
3753 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
3756 *) Extended the ASN.1 parser routines.
3759 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
3762 *) Added a BN_CTX to the BN library.
3765 *) Fixed the weak key values in DES library
3768 *) Changed API in EVP library for cipher aliases.
3771 *) Added support for RC2/64bit cipher.
3774 *) Converted the lhash library to the crypto/mem.c functions.
3777 *) Added more recognized ASN.1 object ids.
3780 *) Added more RSA padding checks for SSL/TLS.
3783 *) Added BIO proxy/filter functionality.
3786 *) Added extra_certs to SSL_CTX which can be used
3787 send extra CA certificates to the client in the CA cert chain sending
3788 process. It can be configured with SSL_CTX_add_extra_chain_cert().
3791 *) Now Fortezza is denied in the authentication phase because
3792 this is key exchange mechanism is not supported by SSLeay at all.
3795 *) Additional PKCS1 checks.
3798 *) Support the string "TLSv1" for all TLS v1 ciphers.
3801 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
3802 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
3805 *) Fixed a few memory leaks.
3808 *) Fixed various code and comment typos.
3811 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
3812 bytes sent in the client random.
