6 Changes between 0.9.2b and 0.9.3
8 *) New function SSL_CTX_use_certificate_chain_file that sets the
9 "extra_cert"s in addition to the certificate. (This makes sense
10 only for "PEM" format files, as chains as a whole are not
14 *) Support verify_depth from the SSL API.
15 x509_vfy.c had what can be considered an off-by-one-error:
16 Its depth (which was not part of the external interface)
17 was actually counting the number of certificates in a chain;
18 now it really counts the depth.
21 *) New function SSL_CTX_set_session_id_context that allows to set a default
22 value (so that you don't need SSL_set_session_id_context for each
23 connection using the SSL_CTX).
26 *) OAEP decoding bug fix.
29 *) Support INSTALL_PREFIX for package builders, as proposed by
33 *) New Configure options "threads" and "no-threads". For systems
34 where the proper compiler options are known (currently Solaris
35 and Linux), "threads" is the default.
38 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
41 *) Install various scripts to $(OPENSSLDIR)/misc, not to
42 $(INSTALLTOP)/bin -- they shouldn't clutter directories
43 such as /usr/local/bin.
46 *) "make linux-shared" to build shared libraries.
47 [Niels Poppe <niels@netbox.org>]
49 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
52 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
53 extension adding in x509 utility.
56 *) Remove NOPROTO sections and error code comments.
59 *) Partial rewrite of the DEF file generator to now parse the ANSI
63 *) New Configure options --prefix=DIR and --openssldir=DIR.
66 *) Complete rewrite of the error code script(s). It is all now handled
67 by one script at the top level which handles error code gathering,
68 header rewriting and C source file generation. It should be much better
69 than the old method: it now uses a modified version of Ulf's parser to
70 read the ANSI prototypes in all header files (thus the old K&R definitions
71 aren't needed for error creation any more) and do a better job of
72 translating function codes into names. The old 'ASN1 error code imbedded
73 in a comment' is no longer necessary and it doesn't use .err files which
74 have now been deleted. Also the error code call doesn't have to appear all
75 on one line (which resulted in some large lines...).
78 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
81 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
82 0 (which usually indicates a closed connection), but continue reading.
85 *) Fix some race conditions.
88 *) Add support for CRL distribution points extension. Add Certificate
89 Policies and CRL distribution points documentation.
92 *) Move the autogenerated header file parts to crypto/opensslconf.h.
95 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
96 8 of keying material. Merlin has also confirmed interop with this fix
97 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
98 [Merlin Hughes <merlin@baltimore.ie>]
100 *) Fix lots of warnings.
101 [Richard Levitte <levitte@stacken.kth.se>]
103 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
104 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
105 [Richard Levitte <levitte@stacken.kth.se>]
107 *) Fix problems with sizeof(long) == 8.
108 [Andy Polyakov <appro@fy.chalmers.se>]
110 *) Change functions to ANSI C.
113 *) Fix typos in error codes.
114 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
116 *) Remove defunct assembler files from Configure.
119 *) SPARC v8 assembler BIGNUM implementation.
120 [Andy Polyakov <appro@fy.chalmers.se>]
122 *) Support for Certificate Policies extension: both print and set.
123 Various additions to support the r2i method this uses.
126 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
127 return a const string when you are expecting an allocated buffer.
130 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
131 types DirectoryString and DisplayText.
134 *) Add code to allow r2i extensions to access the configuration database,
135 add an LHASH database driver and add several ctx helper functions.
138 *) Fix an evil bug in bn_expand2() which caused various BN functions to
139 fail when they extended the size of a BIGNUM.
142 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
143 support typesafe stack.
146 *) Fix typo in SSL_[gs]et_options().
147 [Nils Frostberg <nils@medcom.se>]
149 *) Delete various functions and files that belonged to the (now obsolete)
150 old X509V3 handling code.
153 *) New Configure option "rsaref".
156 *) Don't auto-generate pem.h.
159 *) Introduce type-safe ASN.1 SETs.
162 *) Introduce type-safe STACKs. This will almost certainly break lots of code
163 that links with OpenSSL (well at least cause lots of warnings), but fear
164 not: the conversion is trivial, and it eliminates loads of evil casts. A
165 few STACKed things have been converted already. Feel free to convert more.
166 In the fullness of time, I'll do away with the STACK type altogether.
169 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
170 specified in <certfile> by updating the entry in the index.txt file.
171 This way one no longer has to edit the index.txt file manually for
172 revoking a certificate. The -revoke option does the gory details now.
173 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
175 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
176 `-text' option at all and this way the `-noout -text' combination was
177 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
178 [Ralf S. Engelschall]
180 *) Make sure a corresponding plain text error message exists for the
181 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
182 verify callback function determined that a certificate was revoked.
183 [Ralf S. Engelschall]
185 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
186 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
187 all available cipers including rc5, which was forgotten until now.
188 In order to let the testing shell script know which algorithms
189 are available, a new (up to now undocumented) command
190 "openssl list-cipher-commands" is used.
193 *) Bugfix: s_client occasionally would sleep in select() when
194 it should have checked SSL_pending() first.
197 *) New functions DSA_do_sign and DSA_do_verify to provide access to
198 the raw DSA values prior to ASN.1 encoding.
201 *) Tweaks to Configure
202 Niels Poppe <niels@netbox.org>
204 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
208 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
211 *) New config option to avoid instructions that are illegal on the 80386.
212 The default code is faster, but requires at least a 486.
215 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
216 SSL2_SERVER_VERSION (not used at all) macros, which are now the
217 same as SSL2_VERSION anyway.
220 *) New "-showcerts" option for s_client.
223 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
224 application. Various cleanups and fixes.
227 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
228 modify error routines to work internally. Add error codes and PBE init
229 to library startup routines.
232 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
233 packing functions to asn1 and evp. Changed function names and error
237 *) PKCS12 integration: and so it begins... First of several patches to
238 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
242 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
243 and display support for Thawte strong extranet extension.
246 *) Add LinuxPPC support.
247 [Jeff Dubrule <igor@pobox.org>]
249 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
250 bn_div_words in alpha.s.
251 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
253 *) Make sure the RSA OAEP test is skipped under -DRSAref because
254 OAEP isn't supported when OpenSSL is built with RSAref.
255 [Ulf Moeller <ulf@fitug.de>]
257 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
258 so they no longer are missing under -DNOPROTO.
259 [Soren S. Jorvang <soren@t.dk>]
261 Changes between 0.9.1c and 0.9.2b
263 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
264 doesn't work when the session is reused. Coming soon!
267 *) Fix a security hole, that allows sessions to be reused in the wrong
268 context thus bypassing client cert protection! All software that uses
269 client certs and session caches in multiple contexts NEEDS PATCHING to
270 allow session reuse! A fuller solution is in the works.
271 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
273 *) Some more source tree cleanups (removed obsolete files
274 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
275 permission on "config" script to be executable) and a fix for the INSTALL
277 [Ulf Moeller <ulf@fitug.de>]
279 *) Remove some legacy and erroneous uses of malloc, free instead of
281 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
283 *) Make rsa_oaep_test return non-zero on error.
284 [Ulf Moeller <ulf@fitug.de>]
286 *) Add support for native Solaris shared libraries. Configure
287 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
288 if someone would make that last step automatic.
289 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
291 *) ctx_size was not built with the right compiler during "make links". Fixed.
294 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
295 except NULL ciphers". This means the default cipher list will no longer
296 enable NULL ciphers. They need to be specifically enabled e.g. with
297 the string "DEFAULT:eNULL".
300 *) Fix to RSA private encryption routines: if p < q then it would
301 occasionally produce an invalid result. This will only happen with
302 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
305 *) Be less restrictive and allow also `perl util/perlpath.pl
306 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
307 because this way one can also use an interpreter named `perl5' (which is
308 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
309 installed as `perl').
310 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
312 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
313 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
315 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
316 advapi32.lib to Win32 build and change the pem test comparision
317 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
318 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
319 and crypto/des/ede_cbcm_enc.c.
322 *) DES quad checksum was broken on big-endian architectures. Fixed.
325 *) Comment out two functions in bio.h that aren't implemented. Fix up the
326 Win32 test batch file so it (might) work again. The Win32 test batch file
327 is horrible: I feel ill....
330 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
331 in e_os.h. Audit of header files to check ANSI and non ANSI
332 sections: 10 functions were absent from non ANSI section and not exported
333 from Windows DLLs. Fixed up libeay.num for new functions.
336 *) Make `openssl version' output lines consistent.
337 [Ralf S. Engelschall]
339 *) Fix Win32 symbol export lists for BIO functions: Added
340 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
341 to ms/libeay{16,32}.def.
342 [Ralf S. Engelschall]
344 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
345 fine under Unix and passes some trivial tests I've now added. But the
346 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
347 added to make sure no one expects that this stuff really works in the
348 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
349 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
351 [Ralf S. Engelschall]
353 *) Fix the generation of two part addresses in perl.
354 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
356 *) Add config entry for Linux on MIPS.
357 [John Tobey <jtobey@channel1.com>]
359 *) Make links whenever Configure is run, unless we are on Windoze.
362 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
363 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
367 *) Add a useful kludge to allow package maintainers to specify compiler and
368 other platforms details on the command line without having to patch the
369 Configure script everytime: One now can use ``perl Configure
370 <id>:<details>'', i.e. platform ids are allowed to have details appended
371 to them (seperated by colons). This is treated as there would be a static
372 pre-configured entry in Configure's %table under key <id> with value
373 <details> and ``perl Configure <id>'' is called. So, when you want to
374 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
375 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
376 now, which overrides the FreeBSD-elf entry on-the-fly.
377 [Ralf S. Engelschall]
379 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
382 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
383 on the `perl Configure ...' command line. This way one can compile
384 OpenSSL libraries with Position Independent Code (PIC) which is needed
385 for linking it into DSOs.
386 [Ralf S. Engelschall]
388 *) Remarkably, export ciphers were totally broken and no-one had noticed!
392 *) Cleaned up the LICENSE document: The official contact for any license
393 questions now is the OpenSSL core team under openssl-core@openssl.org.
394 And add a paragraph about the dual-license situation to make sure people
395 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
396 to the OpenSSL toolkit.
397 [Ralf S. Engelschall]
399 *) General source tree makefile cleanups: Made `making xxx in yyy...'
400 display consistent in the source tree and replaced `/bin/rm' by `rm'.
401 Additonally cleaned up the `make links' target: Remove unnecessary
402 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
403 to speed processing and no longer clutter the display with confusing
404 stuff. Instead only the actually done links are displayed.
405 [Ralf S. Engelschall]
407 *) Permit null encryption ciphersuites, used for authentication only. It used
408 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
409 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
413 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
414 signed attributes when verifying signatures (this would break them),
415 the detached data encoding was wrong and public keys obtained using
416 X509_get_pubkey() weren't freed.
419 *) Add text documentation for the BUFFER functions. Also added a work around
420 to a Win95 console bug. This was triggered by the password read stuff: the
421 last character typed gets carried over to the next fread(). If you were
422 generating a new cert request using 'req' for example then the last
423 character of the passphrase would be CR which would then enter the first
427 *) Added the new `Includes OpenSSL Cryptography Software' button as
428 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
429 button and can be used by applications based on OpenSSL to show the
430 relationship to the OpenSSL project.
431 [Ralf S. Engelschall]
433 *) Remove confusing variables in function signatures in files
434 ssl/ssl_lib.c and ssl/ssl.h.
435 [Lennart Bong <lob@kulthea.stacken.kth.se>]
437 *) Don't install bss_file.c under PREFIX/include/
438 [Lennart Bong <lob@kulthea.stacken.kth.se>]
440 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
441 functions that return function pointers and has support for NT specific
442 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
443 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
444 unsigned to signed types: this was killing the Win32 compile.
447 *) Add new certificate file to stack functions,
448 SSL_add_dir_cert_subjects_to_stack() and
449 SSL_add_file_cert_subjects_to_stack(). These largely supplant
450 SSL_load_client_CA_file(), and can be used to add multiple certs easily
451 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
452 This means that Apache-SSL and similar packages don't have to mess around
453 to add as many CAs as they want to the preferred list.
456 *) Experiment with doxygen documentation. Currently only partially applied to
458 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
459 openssl.doxy as the configuration file.
462 *) Get rid of remaining C++-style comments which strict C compilers hate.
463 [Ralf S. Engelschall, pointed out by Carlos Amengual]
465 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
466 compiled in by default: it has problems with large keys.
469 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
470 DH private keys and/or callback functions which directly correspond to
471 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
472 is needed for applications which have to configure certificates on a
473 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
475 For the RSA certificate situation is makes no difference, but
476 for the DSA certificate situation this fixes the "no shared cipher"
477 problem where the OpenSSL cipher selection procedure failed because the
478 temporary keys were not overtaken from the context and the API provided
479 no way to reconfigure them.
480 The new functions now let applications reconfigure the stuff and they
481 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
482 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
483 non-public-API function ssl_cert_instantiate() is used as a helper
484 function and also to reduce code redundancy inside ssl_rsa.c.
485 [Ralf S. Engelschall]
487 *) Move s_server -dcert and -dkey options out of the undocumented feature
488 area because they are useful for the DSA situation and should be
489 recognized by the users.
490 [Ralf S. Engelschall]
492 *) Fix the cipher decision scheme for export ciphers: the export bits are
493 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
494 SSL_EXP_MASK. So, the original variable has to be used instead of the
495 already masked variable.
496 [Richard Levitte <levitte@stacken.kth.se>]
498 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
499 [Richard Levitte <levitte@stacken.kth.se>]
501 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
502 from `int' to `unsigned int' because it's a length and initialized by
503 EVP_DigestFinal() which expects an `unsigned int *'.
504 [Richard Levitte <levitte@stacken.kth.se>]
506 *) Don't hard-code path to Perl interpreter on shebang line of Configure
507 script. Instead use the usual Shell->Perl transition trick.
508 [Ralf S. Engelschall]
510 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
511 (in addition to RSA certificates) to match the behaviour of `openssl dsa
512 -noout -modulus' as it's already the case for `openssl rsa -noout
513 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
514 currently the public key is printed (a decision which was already done by
515 `openssl dsa -modulus' in the past) which serves a similar purpose.
516 Additionally the NO_RSA no longer completely removes the whole -modulus
517 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
519 [Ralf S. Engelschall]
521 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
522 BIO. See the source (crypto/evp/bio_ok.c) for more info.
523 [Arne Ansper <arne@ats.cyber.ee>]
525 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
526 to be added. Now both 'req' and 'ca' can use new objects defined in the
530 *) Add cool BIO that does syslog (or event log on NT).
531 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
533 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
534 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
535 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
536 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
539 *) Add preliminary config info for new extension code.
542 *) Make RSA_NO_PADDING really use no padding.
543 [Ulf Moeller <ulf@fitug.de>]
545 *) Generate errors when private/public key check is done.
548 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
549 for some CRL extensions and new objects added.
552 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
553 key usage extension and fuller support for authority key id.
556 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
557 padding method for RSA, which is recommended for new applications in PKCS
558 #1 v2.0 (RFC 2437, October 1998).
559 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
560 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
561 against Bleichbacher's attack on RSA.
562 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
565 *) Updates to the new SSL compression code
566 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
568 *) Fix so that the version number in the master secret, when passed
569 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
570 (because the server will not accept higher), that the version number
571 is 0x03,0x01, not 0x03,0x00
572 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
574 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
575 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
576 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
579 *) Support for RAW extensions where an arbitrary extension can be
580 created by including its DER encoding. See apps/openssl.cnf for
584 *) Make sure latest Perl versions don't interpret some generated C array
585 code as Perl array code in the crypto/err/err_genc.pl script.
586 [Lars Weber <3weber@informatik.uni-hamburg.de>]
588 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
589 not many people have the assembler. Various Win32 compilation fixes and
590 update to the INSTALL.W32 file with (hopefully) more accurate Win32
594 *) Modify configure script 'Configure' to automatically create crypto/date.h
595 file under Win32 and also build pem.h from pem.org. New script
596 util/mkfiles.pl to create the MINFO file on environments that can't do a
597 'make files': perl util/mkfiles.pl >MINFO should work.
600 *) Major rework of DES function declarations, in the pursuit of correctness
601 and purity. As a result, many evil casts evaporated, and some weirdness,
602 too. You may find this causes warnings in your code. Zapping your evil
603 casts will probably fix them. Mostly.
606 *) Fix for a typo in asn1.h. Bug fix to object creation script
607 obj_dat.pl. It considered a zero in an object definition to mean
608 "end of object": none of the objects in objects.h have any zeros
609 so it wasn't spotted.
610 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
612 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
613 Masking (CBCM). In the absence of test vectors, the best I have been able
614 to do is check that the decrypt undoes the encrypt, so far. Send me test
615 vectors if you have them.
618 *) Correct calculation of key length for export ciphers (too much space was
619 allocated for null ciphers). This has not been tested!
622 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
623 message is now correct (it understands "crypto" and "ssl" on its
624 command line). There is also now an "update" option. This will update
625 the util/ssleay.num and util/libeay.num files with any new functions.
627 perl util/mkdef.pl crypto ssl update
631 *) Overhauled the Perl interface (perl/*):
632 - ported BN stuff to OpenSSL's different BN library
633 - made the perl/ source tree CVS-aware
634 - renamed the package from SSLeay to OpenSSL (the files still contain
635 their history because I've copied them in the repository)
636 - removed obsolete files (the test scripts will be replaced
637 by better Test::Harness variants in the future)
638 [Ralf S. Engelschall]
640 *) First cut for a very conservative source tree cleanup:
641 1. merge various obsolete readme texts into doc/ssleay.txt
642 where we collect the old documents and readme texts.
643 2. remove the first part of files where I'm already sure that we no
644 longer need them because of three reasons: either they are just temporary
645 files which were left by Eric or they are preserved original files where
646 I've verified that the diff is also available in the CVS via "cvs diff
647 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
648 the crypto/md/ stuff).
649 [Ralf S. Engelschall]
651 *) More extension code. Incomplete support for subject and issuer alt
652 name, issuer and authority key id. Change the i2v function parameters
653 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
654 what that's for :-) Fix to ASN1 macro which messed up
655 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
658 *) Preliminary support for ENUMERATED type. This is largely copied from the
662 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
663 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
665 *) Make sure `make rehash' target really finds the `openssl' program.
666 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
668 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
669 like to hear about it if this slows down other processors.
672 *) Add CygWin32 platform information to Configure script.
673 [Alan Batie <batie@aahz.jf.intel.com>]
675 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
676 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
678 *) New program nseq to manipulate netscape certificate sequences
681 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
685 *) Fixes to BN code. Previously the default was to define BN_RECURSION
686 but the BN code had some problems that would cause failures when
687 doing certificate verification and some other functions.
688 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
690 *) Add ASN1 and PEM code to support netscape certificate sequences.
693 *) Add ASN1 and PEM code to support netscape certificate sequences.
696 *) Add several PKIX and private extended key usage OIDs.
699 *) Modify the 'ca' program to handle the new extension code. Modify
700 openssl.cnf for new extension format, add comments.
703 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
704 and add a sample to openssl.cnf so req -x509 now adds appropriate
708 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
709 error code, add initial support to X509_print() and x509 application.
712 *) Takes a deep breath and start addding X509 V3 extension support code. Add
713 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
714 stuff is currently isolated and isn't even compiled yet.
717 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
718 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
719 Removed the versions check from X509 routines when loading extensions:
720 this allows certain broken certificates that don't set the version
721 properly to be processed.
724 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
725 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
726 can still be regenerated with "make depend".
729 *) Spelling mistake in C version of CAST-128.
730 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
732 *) Changes to the error generation code. The perl script err-code.pl
733 now reads in the old error codes and retains the old numbers, only
734 adding new ones if necessary. It also only changes the .err files if new
735 codes are added. The makefiles have been modified to only insert errors
736 when needed (to avoid needlessly modifying header files). This is done
737 by only inserting errors if the .err file is newer than the auto generated
738 C file. To rebuild all the error codes from scratch (the old behaviour)
739 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
740 or delete all the .err files.
743 *) CAST-128 was incorrectly implemented for short keys. The C version has
744 been fixed, but is untested. The assembler versions are also fixed, but
745 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
746 to regenerate it if needed.
747 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
748 Hagino <itojun@kame.net>]
750 *) File was opened incorrectly in randfile.c.
751 [Ulf Möller <ulf@fitug.de>]
753 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
754 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
755 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
756 al: it's just almost always a UTCTime. Note this patch adds new error
757 codes so do a "make errors" if there are problems.
760 *) Correct Linux 1 recognition in config.
761 [Ulf Möller <ulf@fitug.de>]
763 *) Remove pointless MD5 hash when using DSA keys in ca.
764 [Anonymous <nobody@replay.com>]
766 *) Generate an error if given an empty string as a cert directory. Also
767 generate an error if handed NULL (previously returned 0 to indicate an
768 error, but didn't set one).
769 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
771 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
774 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
775 parameters. This was causing a warning which killed off the Win32 compile.
778 *) Remove C++ style comments from crypto/bn/bn_local.h.
779 [Neil Costigan <neil.costigan@celocom.com>]
781 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
782 based on a text string, looking up short and long names and finally
783 "dot" format. The "dot" format stuff didn't work. Added new function
784 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
785 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
786 OID is not part of the table.
789 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
790 X509_LOOKUP_by_alias().
793 *) Sort openssl functions by name.
796 *) Get the gendsa program working (hopefully) and add it to app list. Remove
797 encryption from sample DSA keys (in case anyone is interested the password
801 *) Make _all_ *_free functions accept a NULL pointer.
802 [Frans Heymans <fheymans@isaserver.be>]
804 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
806 [Anonymous <nobody@replay.com>]
808 *) s_server should send the CAfile as acceptable CAs, not its own cert.
809 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
811 *) Don't blow it for numeric -newkey arguments to apps/req.
812 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
814 *) Temp key "for export" tests were wrong in s3_srvr.c.
815 [Anonymous <nobody@replay.com>]
817 *) Add prototype for temp key callback functions
818 SSL_CTX_set_tmp_{rsa,dh}_callback().
821 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
822 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
825 *) X509_name_add_entry() freed the wrong thing after an error.
826 [Arne Ansper <arne@ats.cyber.ee>]
828 *) rsa_eay.c would attempt to free a NULL context.
829 [Arne Ansper <arne@ats.cyber.ee>]
831 *) BIO_s_socket() had a broken should_retry() on Windoze.
832 [Arne Ansper <arne@ats.cyber.ee>]
834 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
835 [Arne Ansper <arne@ats.cyber.ee>]
837 *) Make sure the already existing X509_STORE->depth variable is initialized
838 in X509_STORE_new(), but document the fact that this variable is still
839 unused in the certificate verification process.
840 [Ralf S. Engelschall]
842 *) Fix the various library and apps files to free up pkeys obtained from
843 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
846 *) Fix reference counting in X509_PUBKEY_get(). This makes
847 demos/maurice/example2.c work, amongst others, probably.
848 [Steve Henson and Ben Laurie]
850 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
851 `openssl' and second, the shortcut symlinks for the `openssl <command>'
852 are no longer created. This way we have a single and consistent command
853 line interface `openssl <command>', similar to `cvs <command>'.
854 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
856 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
857 BIT STRING wrapper always have zero unused bits.
860 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
863 *) Make the top-level INSTALL documentation easier to understand.
866 *) Makefiles updated to exit if an error occurs in a sub-directory
867 make (including if user presses ^C) [Paul Sutton]
869 *) Make Montgomery context stuff explicit in RSA data structure.
872 *) Fix build order of pem and err to allow for generated pem.h.
875 *) Fix renumbering bug in X509_NAME_delete_entry().
878 *) Enhanced the err-ins.pl script so it makes the error library number
879 global and can add a library name. This is needed for external ASN1 and
880 other error libraries.
883 *) Fixed sk_insert which never worked properly.
886 *) Fix ASN1 macros so they can handle indefinite length construted
887 EXPLICIT tags. Some non standard certificates use these: they can now
891 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
892 into a single doc/ssleay.txt bundle. This way the information is still
893 preserved but no longer messes up this directory. Now it's new room for
894 the new set of documenation files.
895 [Ralf S. Engelschall]
897 *) SETs were incorrectly DER encoded. This was a major pain, because they
898 shared code with SEQUENCEs, which aren't coded the same. This means that
899 almost everything to do with SETs or SEQUENCEs has either changed name or
901 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
903 *) Fix test data to work with the above.
906 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
907 was already fixed by Eric for 0.9.1 it seems.
908 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
910 *) Autodetect FreeBSD3.
913 *) Fix various bugs in Configure. This affects the following platforms:
921 *) Eliminate generated files from CVS. Reorder tests to regenerate files
922 before they are needed.
925 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
928 Changes between 0.9.1b and 0.9.1c
930 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
931 changed SSLeay to OpenSSL in version strings.
932 [Ralf S. Engelschall]
934 *) Some fixups to the top-level documents.
937 *) Fixed the nasty bug where rsaref.h was not found under compile-time
938 because the symlink to include/ was missing.
939 [Ralf S. Engelschall]
941 *) Incorporated the popular no-RSA/DSA-only patches
942 which allow to compile a RSA-free SSLeay.
943 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
945 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
946 when "ssleay" is still not found.
947 [Ralf S. Engelschall]
949 *) Added more platforms to Configure: Cray T3E, HPUX 11,
950 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
952 *) Updated the README file.
953 [Ralf S. Engelschall]
955 *) Added various .cvsignore files in the CVS repository subdirs
956 to make a "cvs update" really silent.
957 [Ralf S. Engelschall]
959 *) Recompiled the error-definition header files and added
960 missing symbols to the Win32 linker tables.
961 [Ralf S. Engelschall]
963 *) Cleaned up the top-level documents;
964 o new files: CHANGES and LICENSE
965 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
966 o merged COPYRIGHT into LICENSE
967 o removed obsolete TODO file
968 o renamed MICROSOFT to INSTALL.W32
969 [Ralf S. Engelschall]
971 *) Removed dummy files from the 0.9.1b source tree:
972 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
973 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
974 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f

976 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
977 [Ralf S. Engelschall]
979 *) Added various platform portability fixes.
982 *) The Genesis of the OpenSSL rpject:
983 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
984 Young and Tim J. Hudson created while they were working for C2Net until
986 [The OpenSSL Project]
988 Changes between 0.9.0b and 0.9.1b
990 *) Updated a few CA certificates under certs/
993 *) Changed some BIGNUM api stuff.
996 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
997 DGUX x86, Linux Alpha, etc.
1000 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1001 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1005 *) Add -strparse option to asn1pars program which parses nested
1007 [Dr Stephen Henson <shenson@bigfoot.com>]
1009 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1012 *) DSA fix for "ca" program.
1015 *) Added "-genkey" option to "dsaparam" program.
1018 *) Added RIPE MD160 (rmd160) message digest.
1021 *) Added -a (all) option to "ssleay version" command.
1024 *) Added PLATFORM define which is the id given to Configure.
1027 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1030 *) Extended the ASN.1 parser routines.
1033 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1036 *) Added a BN_CTX to the BN library.
1039 *) Fixed the weak key values in DES library
1042 *) Changed API in EVP library for cipher aliases.
1045 *) Added support for RC2/64bit cipher.
1048 *) Converted the lhash library to the crypto/mem.c functions.
1051 *) Added more recognized ASN.1 object ids.
1054 *) Added more RSA padding checks for SSL/TLS.
1057 *) Added BIO proxy/filter functionality.
1060 *) Added extra_certs to SSL_CTX which can be used
1061 send extra CA certificates to the client in the CA cert chain sending
1062 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1065 *) Now Fortezza is denied in the authentication phase because
1066 this is key exchange mechanism is not supported by SSLeay at all.
1069 *) Additional PKCS1 checks.
1072 *) Support the string "TLSv1" for all TLS v1 ciphers.
1075 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1076 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1079 *) Fixed a few memory leaks.
1082 *) Fixed various code and comment typos.
1085 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1086 bytes sent in the client random.
