6 Changes between 0.9.3a and 0.9.4
8 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
9 and partial PKCS#8 functionality. New 'pkcs8' application linked to
13 *) Introduce some semblance of const correctness to BN. Shame C doesn't
17 *) "linux-sparc64-gcc" configuration (ultrapenguin).
18 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
20 *) config now generates no-xxx options for missing ciphers.
23 *) Support the EBCDIC character set (work in progress).
24 File ebcdic.c not yet included because it has a different license.
25 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
27 *) Support BS2000/OSD-POSIX.
28 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
30 *) Make callbacks for key generation use void * instead of char *.
33 *) Make S/MIME samples compile (not yet tested).
36 *) Additional typesafe stacks.
39 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
43 Changes between 0.9.3 and 0.9.3a [29 May 1999]
45 *) New configuration variant "sco5-gcc".
47 *) Updated some demos.
48 [Sean O Riordain, Wade Scholine]
50 *) Add missing BIO_free at exit of pkcs12 application.
53 *) Fix memory leak in conf.c.
56 *) Updates for Win32 to assembler version of MD5.
59 *) Set #! path to perl in apps/der_chop to where we found it
60 instead of using a fixed path.
63 *) SHA library changes for irix64-mips4-cc.
66 *) Improvements for VMS support.
70 Changes between 0.9.2b and 0.9.3 [24 May 1999]
72 *) Bignum library bug fix. IRIX 6 passes "make test" now!
73 This also avoids the problems with SC4.2 and unpatched SC5.
74 [Andy Polyakov <appro@fy.chalmers.se>]
76 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
77 These are required because of the typesafe stack would otherwise break
78 existing code. If old code used a structure member which used to be STACK
79 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
80 sk_num or sk_value it would produce an error because the num, data members
81 are not present in STACK_OF. Now it just produces a warning. sk_set
82 replaces the old method of assigning a value to sk_value
83 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
84 that does this will no longer work (and should use sk_set instead) but
85 this could be regarded as a "questionable" behaviour anyway.
88 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
89 correctly handle encrypted S/MIME data.
92 *) Change type of various DES function arguments from des_cblock
93 (which means, in function argument declarations, pointer to char)
94 to des_cblock * (meaning pointer to array with 8 char elements),
95 which allows the compiler to do more typechecking; it was like
96 that back in SSLeay, but with lots of ugly casts.
98 Introduce new type const_des_cblock.
101 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
102 problems: find RecipientInfo structure that matches recipient certificate
103 and initialise the ASN1 structures properly based on passed cipher.
106 *) Belatedly make the BN tests actually check the results.
109 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
110 to and from BNs: it was completely broken. New compilation option
111 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
112 key elements as negative integers.
115 *) Reorganize and speed up MD5.
116 [Andy Polyakov <appro@fy.chalmers.se>]
119 [Richard Levitte <richard@levitte.org>]
121 *) New option -out to asn1parse to allow the parsed structure to be
122 output to a file. This is most useful when combined with the -strparse
123 option to examine the output of things like OCTET STRINGS.
126 *) Make SSL library a little more fool-proof by not requiring any longer
127 that SSL_set_{accept,connect}_state be called before
128 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
129 in many applications because usually everything *appeared* to work as
130 intended anyway -- now it really works as intended).
133 *) Move openssl.cnf out of lib/.
136 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
137 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
138 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
139 [Ralf S. Engelschall]
141 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
142 handle PKCS#7 enveloped data properly.
143 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
145 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
146 copying pointers. The cert_st handling is changed by this in
147 various ways (and thus what used to be known as ctx->default_cert
148 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
149 any longer when s->cert does not give us what we need).
150 ssl_cert_instantiate becomes obsolete by this change.
151 As soon as we've got the new code right (possibly it already is?),
152 we have solved a couple of bugs of the earlier code where s->cert
153 was used as if it could not have been shared with other SSL structures.
155 Note that using the SSL API in certain dirty ways now will result
156 in different behaviour than observed with earlier library versions:
157 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
158 does not influence s as it used to.
160 In order to clean up things more thoroughly, inside SSL_SESSION
161 we don't use CERT any longer, but a new structure SESS_CERT
162 that holds per-session data (if available); currently, this is
163 the peer's certificate chain and, for clients, the server's certificate
164 and temporary key. CERT holds only those values that can have
165 meaningful defaults in an SSL_CTX.
168 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
169 from the internal representation. Various PKCS#7 fixes: remove some
170 evil casts and set the enc_dig_alg field properly based on the signing
174 *) Allow PKCS#12 password to be set from the command line or the
175 environment. Let 'ca' get its config file name from the environment
176 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
180 *) Allow certificate policies extension to use an IA5STRING for the
181 organization field. This is contrary to the PKIX definition but
182 VeriSign uses it and IE5 only recognises this form. Document 'x509'
186 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
187 without disallowing inline assembler and the like for non-pedantic builds.
190 *) Support Borland C++ builder.
191 [Janez Jere <jj@void.si>, modified by Ulf Möller]
196 *) SHA-1 cleanups and performance enhancements.
197 [Andy Polyakov <appro@fy.chalmers.se>]
199 *) Sparc v8plus assembler for the bignum library.
200 [Andy Polyakov <appro@fy.chalmers.se>]
202 *) Accept any -xxx and +xxx compiler options in Configure.
205 *) Update HPUX configuration.
208 *) Add missing sk_<type>_unshift() function to safestack.h
209 [Ralf S. Engelschall]
211 *) New function SSL_CTX_use_certificate_chain_file that sets the
212 "extra_cert"s in addition to the certificate. (This makes sense
213 only for "PEM" format files, as chains as a whole are not
217 *) Support verify_depth from the SSL API.
218 x509_vfy.c had what can be considered an off-by-one-error:
219 Its depth (which was not part of the external interface)
220 was actually counting the number of certificates in a chain;
221 now it really counts the depth.
224 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
225 instead of X509err, which often resulted in confusing error
226 messages since the error codes are not globally unique
227 (e.g. an alleged error in ssl3_accept when a certificate
228 didn't match the private key).
230 *) New function SSL_CTX_set_session_id_context that allows to set a default
231 value (so that you don't need SSL_set_session_id_context for each
232 connection using the SSL_CTX).
235 *) OAEP decoding bug fix.
238 *) Support INSTALL_PREFIX for package builders, as proposed by
242 *) New Configure options "threads" and "no-threads". For systems
243 where the proper compiler options are known (currently Solaris
244 and Linux), "threads" is the default.
247 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
250 *) Install various scripts to $(OPENSSLDIR)/misc, not to
251 $(INSTALLTOP)/bin -- they shouldn't clutter directories
252 such as /usr/local/bin.
255 *) "make linux-shared" to build shared libraries.
256 [Niels Poppe <niels@netbox.org>]
258 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
261 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
262 extension adding in x509 utility.
265 *) Remove NOPROTO sections and error code comments.
268 *) Partial rewrite of the DEF file generator to now parse the ANSI
272 *) New Configure options --prefix=DIR and --openssldir=DIR.
275 *) Complete rewrite of the error code script(s). It is all now handled
276 by one script at the top level which handles error code gathering,
277 header rewriting and C source file generation. It should be much better
278 than the old method: it now uses a modified version of Ulf's parser to
279 read the ANSI prototypes in all header files (thus the old K&R definitions
280 aren't needed for error creation any more) and do a better job of
281 translating function codes into names. The old 'ASN1 error code imbedded
282 in a comment' is no longer necessary and it doesn't use .err files which
283 have now been deleted. Also the error code call doesn't have to appear all
284 on one line (which resulted in some large lines...).
287 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
290 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
291 0 (which usually indicates a closed connection), but continue reading.
294 *) Fix some race conditions.
297 *) Add support for CRL distribution points extension. Add Certificate
298 Policies and CRL distribution points documentation.
301 *) Move the autogenerated header file parts to crypto/opensslconf.h.
304 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
305 8 of keying material. Merlin has also confirmed interop with this fix
306 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
307 [Merlin Hughes <merlin@baltimore.ie>]
309 *) Fix lots of warnings.
310 [Richard Levitte <levitte@stacken.kth.se>]
312 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
313 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
314 [Richard Levitte <levitte@stacken.kth.se>]
316 *) Fix problems with sizeof(long) == 8.
317 [Andy Polyakov <appro@fy.chalmers.se>]
319 *) Change functions to ANSI C.
322 *) Fix typos in error codes.
323 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
325 *) Remove defunct assembler files from Configure.
328 *) SPARC v8 assembler BIGNUM implementation.
329 [Andy Polyakov <appro@fy.chalmers.se>]
331 *) Support for Certificate Policies extension: both print and set.
332 Various additions to support the r2i method this uses.
335 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
336 return a const string when you are expecting an allocated buffer.
339 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
340 types DirectoryString and DisplayText.
343 *) Add code to allow r2i extensions to access the configuration database,
344 add an LHASH database driver and add several ctx helper functions.
347 *) Fix an evil bug in bn_expand2() which caused various BN functions to
348 fail when they extended the size of a BIGNUM.
351 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
352 support typesafe stack.
355 *) Fix typo in SSL_[gs]et_options().
356 [Nils Frostberg <nils@medcom.se>]
358 *) Delete various functions and files that belonged to the (now obsolete)
359 old X509V3 handling code.
362 *) New Configure option "rsaref".
365 *) Don't auto-generate pem.h.
368 *) Introduce type-safe ASN.1 SETs.
371 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
372 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
374 *) Introduce type-safe STACKs. This will almost certainly break lots of code
375 that links with OpenSSL (well at least cause lots of warnings), but fear
376 not: the conversion is trivial, and it eliminates loads of evil casts. A
377 few STACKed things have been converted already. Feel free to convert more.
378 In the fullness of time, I'll do away with the STACK type altogether.
381 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
382 specified in <certfile> by updating the entry in the index.txt file.
383 This way one no longer has to edit the index.txt file manually for
384 revoking a certificate. The -revoke option does the gory details now.
385 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
387 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
388 `-text' option at all and this way the `-noout -text' combination was
389 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
390 [Ralf S. Engelschall]
392 *) Make sure a corresponding plain text error message exists for the
393 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
394 verify callback function determined that a certificate was revoked.
395 [Ralf S. Engelschall]
397 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
398 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
399 all available cipers including rc5, which was forgotten until now.
400 In order to let the testing shell script know which algorithms
401 are available, a new (up to now undocumented) command
402 "openssl list-cipher-commands" is used.
405 *) Bugfix: s_client occasionally would sleep in select() when
406 it should have checked SSL_pending() first.
409 *) New functions DSA_do_sign and DSA_do_verify to provide access to
410 the raw DSA values prior to ASN.1 encoding.
413 *) Tweaks to Configure
414 [Niels Poppe <niels@netbox.org>]
416 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
420 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
423 *) New config option to avoid instructions that are illegal on the 80386.
424 The default code is faster, but requires at least a 486.
427 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
428 SSL2_SERVER_VERSION (not used at all) macros, which are now the
429 same as SSL2_VERSION anyway.
432 *) New "-showcerts" option for s_client.
435 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
436 application. Various cleanups and fixes.
439 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
440 modify error routines to work internally. Add error codes and PBE init
441 to library startup routines.
444 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
445 packing functions to asn1 and evp. Changed function names and error
449 *) PKCS12 integration: and so it begins... First of several patches to
450 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
454 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
455 and display support for Thawte strong extranet extension.
458 *) Add LinuxPPC support.
459 [Jeff Dubrule <igor@pobox.org>]
461 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
462 bn_div_words in alpha.s.
463 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
465 *) Make sure the RSA OAEP test is skipped under -DRSAref because
466 OAEP isn't supported when OpenSSL is built with RSAref.
467 [Ulf Moeller <ulf@fitug.de>]
469 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
470 so they no longer are missing under -DNOPROTO.
471 [Soren S. Jorvang <soren@t.dk>]
474 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
476 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
477 doesn't work when the session is reused. Coming soon!
480 *) Fix a security hole, that allows sessions to be reused in the wrong
481 context thus bypassing client cert protection! All software that uses
482 client certs and session caches in multiple contexts NEEDS PATCHING to
483 allow session reuse! A fuller solution is in the works.
484 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
486 *) Some more source tree cleanups (removed obsolete files
487 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
488 permission on "config" script to be executable) and a fix for the INSTALL
490 [Ulf Moeller <ulf@fitug.de>]
492 *) Remove some legacy and erroneous uses of malloc, free instead of
494 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
496 *) Make rsa_oaep_test return non-zero on error.
497 [Ulf Moeller <ulf@fitug.de>]
499 *) Add support for native Solaris shared libraries. Configure
500 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
501 if someone would make that last step automatic.
502 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
504 *) ctx_size was not built with the right compiler during "make links". Fixed.
507 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
508 except NULL ciphers". This means the default cipher list will no longer
509 enable NULL ciphers. They need to be specifically enabled e.g. with
510 the string "DEFAULT:eNULL".
513 *) Fix to RSA private encryption routines: if p < q then it would
514 occasionally produce an invalid result. This will only happen with
515 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
518 *) Be less restrictive and allow also `perl util/perlpath.pl
519 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
520 because this way one can also use an interpreter named `perl5' (which is
521 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
522 installed as `perl').
523 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
525 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
526 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
528 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
529 advapi32.lib to Win32 build and change the pem test comparision
530 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
531 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
532 and crypto/des/ede_cbcm_enc.c.
535 *) DES quad checksum was broken on big-endian architectures. Fixed.
538 *) Comment out two functions in bio.h that aren't implemented. Fix up the
539 Win32 test batch file so it (might) work again. The Win32 test batch file
540 is horrible: I feel ill....
543 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
544 in e_os.h. Audit of header files to check ANSI and non ANSI
545 sections: 10 functions were absent from non ANSI section and not exported
546 from Windows DLLs. Fixed up libeay.num for new functions.
549 *) Make `openssl version' output lines consistent.
550 [Ralf S. Engelschall]
552 *) Fix Win32 symbol export lists for BIO functions: Added
553 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
554 to ms/libeay{16,32}.def.
555 [Ralf S. Engelschall]
557 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
558 fine under Unix and passes some trivial tests I've now added. But the
559 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
560 added to make sure no one expects that this stuff really works in the
561 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
562 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
564 [Ralf S. Engelschall]
566 *) Fix the generation of two part addresses in perl.
567 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
569 *) Add config entry for Linux on MIPS.
570 [John Tobey <jtobey@channel1.com>]
572 *) Make links whenever Configure is run, unless we are on Windoze.
575 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
576 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
580 *) Add a useful kludge to allow package maintainers to specify compiler and
581 other platforms details on the command line without having to patch the
582 Configure script everytime: One now can use ``perl Configure
583 <id>:<details>'', i.e. platform ids are allowed to have details appended
584 to them (seperated by colons). This is treated as there would be a static
585 pre-configured entry in Configure's %table under key <id> with value
586 <details> and ``perl Configure <id>'' is called. So, when you want to
587 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
588 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
589 now, which overrides the FreeBSD-elf entry on-the-fly.
590 [Ralf S. Engelschall]
592 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
595 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
596 on the `perl Configure ...' command line. This way one can compile
597 OpenSSL libraries with Position Independent Code (PIC) which is needed
598 for linking it into DSOs.
599 [Ralf S. Engelschall]
601 *) Remarkably, export ciphers were totally broken and no-one had noticed!
605 *) Cleaned up the LICENSE document: The official contact for any license
606 questions now is the OpenSSL core team under openssl-core@openssl.org.
607 And add a paragraph about the dual-license situation to make sure people
608 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
609 to the OpenSSL toolkit.
610 [Ralf S. Engelschall]
612 *) General source tree makefile cleanups: Made `making xxx in yyy...'
613 display consistent in the source tree and replaced `/bin/rm' by `rm'.
614 Additonally cleaned up the `make links' target: Remove unnecessary
615 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
616 to speed processing and no longer clutter the display with confusing
617 stuff. Instead only the actually done links are displayed.
618 [Ralf S. Engelschall]
620 *) Permit null encryption ciphersuites, used for authentication only. It used
621 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
622 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
626 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
627 signed attributes when verifying signatures (this would break them),
628 the detached data encoding was wrong and public keys obtained using
629 X509_get_pubkey() weren't freed.
632 *) Add text documentation for the BUFFER functions. Also added a work around
633 to a Win95 console bug. This was triggered by the password read stuff: the
634 last character typed gets carried over to the next fread(). If you were
635 generating a new cert request using 'req' for example then the last
636 character of the passphrase would be CR which would then enter the first
640 *) Added the new `Includes OpenSSL Cryptography Software' button as
641 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
642 button and can be used by applications based on OpenSSL to show the
643 relationship to the OpenSSL project.
644 [Ralf S. Engelschall]
646 *) Remove confusing variables in function signatures in files
647 ssl/ssl_lib.c and ssl/ssl.h.
648 [Lennart Bong <lob@kulthea.stacken.kth.se>]
650 *) Don't install bss_file.c under PREFIX/include/
651 [Lennart Bong <lob@kulthea.stacken.kth.se>]
653 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
654 functions that return function pointers and has support for NT specific
655 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
656 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
657 unsigned to signed types: this was killing the Win32 compile.
660 *) Add new certificate file to stack functions,
661 SSL_add_dir_cert_subjects_to_stack() and
662 SSL_add_file_cert_subjects_to_stack(). These largely supplant
663 SSL_load_client_CA_file(), and can be used to add multiple certs easily
664 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
665 This means that Apache-SSL and similar packages don't have to mess around
666 to add as many CAs as they want to the preferred list.
669 *) Experiment with doxygen documentation. Currently only partially applied to
671 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
672 openssl.doxy as the configuration file.
675 *) Get rid of remaining C++-style comments which strict C compilers hate.
676 [Ralf S. Engelschall, pointed out by Carlos Amengual]
678 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
679 compiled in by default: it has problems with large keys.
682 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
683 DH private keys and/or callback functions which directly correspond to
684 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
685 is needed for applications which have to configure certificates on a
686 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
688 For the RSA certificate situation is makes no difference, but
689 for the DSA certificate situation this fixes the "no shared cipher"
690 problem where the OpenSSL cipher selection procedure failed because the
691 temporary keys were not overtaken from the context and the API provided
692 no way to reconfigure them.
693 The new functions now let applications reconfigure the stuff and they
694 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
695 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
696 non-public-API function ssl_cert_instantiate() is used as a helper
697 function and also to reduce code redundancy inside ssl_rsa.c.
698 [Ralf S. Engelschall]
700 *) Move s_server -dcert and -dkey options out of the undocumented feature
701 area because they are useful for the DSA situation and should be
702 recognized by the users.
703 [Ralf S. Engelschall]
705 *) Fix the cipher decision scheme for export ciphers: the export bits are
706 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
707 SSL_EXP_MASK. So, the original variable has to be used instead of the
708 already masked variable.
709 [Richard Levitte <levitte@stacken.kth.se>]
711 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
712 [Richard Levitte <levitte@stacken.kth.se>]
714 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
715 from `int' to `unsigned int' because it's a length and initialized by
716 EVP_DigestFinal() which expects an `unsigned int *'.
717 [Richard Levitte <levitte@stacken.kth.se>]
719 *) Don't hard-code path to Perl interpreter on shebang line of Configure
720 script. Instead use the usual Shell->Perl transition trick.
721 [Ralf S. Engelschall]
723 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
724 (in addition to RSA certificates) to match the behaviour of `openssl dsa
725 -noout -modulus' as it's already the case for `openssl rsa -noout
726 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
727 currently the public key is printed (a decision which was already done by
728 `openssl dsa -modulus' in the past) which serves a similar purpose.
729 Additionally the NO_RSA no longer completely removes the whole -modulus
730 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
732 [Ralf S. Engelschall]
734 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
735 BIO. See the source (crypto/evp/bio_ok.c) for more info.
736 [Arne Ansper <arne@ats.cyber.ee>]
738 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
739 to be added. Now both 'req' and 'ca' can use new objects defined in the
743 *) Add cool BIO that does syslog (or event log on NT).
744 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
746 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
747 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
748 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
749 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
752 *) Add preliminary config info for new extension code.
755 *) Make RSA_NO_PADDING really use no padding.
756 [Ulf Moeller <ulf@fitug.de>]
758 *) Generate errors when private/public key check is done.
761 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
762 for some CRL extensions and new objects added.
765 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
766 key usage extension and fuller support for authority key id.
769 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
770 padding method for RSA, which is recommended for new applications in PKCS
771 #1 v2.0 (RFC 2437, October 1998).
772 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
773 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
774 against Bleichbacher's attack on RSA.
775 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
778 *) Updates to the new SSL compression code
779 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
781 *) Fix so that the version number in the master secret, when passed
782 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
783 (because the server will not accept higher), that the version number
784 is 0x03,0x01, not 0x03,0x00
785 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
787 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
788 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
789 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
792 *) Support for RAW extensions where an arbitrary extension can be
793 created by including its DER encoding. See apps/openssl.cnf for
797 *) Make sure latest Perl versions don't interpret some generated C array
798 code as Perl array code in the crypto/err/err_genc.pl script.
799 [Lars Weber <3weber@informatik.uni-hamburg.de>]
801 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
802 not many people have the assembler. Various Win32 compilation fixes and
803 update to the INSTALL.W32 file with (hopefully) more accurate Win32
807 *) Modify configure script 'Configure' to automatically create crypto/date.h
808 file under Win32 and also build pem.h from pem.org. New script
809 util/mkfiles.pl to create the MINFO file on environments that can't do a
810 'make files': perl util/mkfiles.pl >MINFO should work.
813 *) Major rework of DES function declarations, in the pursuit of correctness
814 and purity. As a result, many evil casts evaporated, and some weirdness,
815 too. You may find this causes warnings in your code. Zapping your evil
816 casts will probably fix them. Mostly.
819 *) Fix for a typo in asn1.h. Bug fix to object creation script
820 obj_dat.pl. It considered a zero in an object definition to mean
821 "end of object": none of the objects in objects.h have any zeros
822 so it wasn't spotted.
823 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
825 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
826 Masking (CBCM). In the absence of test vectors, the best I have been able
827 to do is check that the decrypt undoes the encrypt, so far. Send me test
828 vectors if you have them.
831 *) Correct calculation of key length for export ciphers (too much space was
832 allocated for null ciphers). This has not been tested!
835 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
836 message is now correct (it understands "crypto" and "ssl" on its
837 command line). There is also now an "update" option. This will update
838 the util/ssleay.num and util/libeay.num files with any new functions.
840 perl util/mkdef.pl crypto ssl update
844 *) Overhauled the Perl interface (perl/*):
845 - ported BN stuff to OpenSSL's different BN library
846 - made the perl/ source tree CVS-aware
847 - renamed the package from SSLeay to OpenSSL (the files still contain
848 their history because I've copied them in the repository)
849 - removed obsolete files (the test scripts will be replaced
850 by better Test::Harness variants in the future)
851 [Ralf S. Engelschall]
853 *) First cut for a very conservative source tree cleanup:
854 1. merge various obsolete readme texts into doc/ssleay.txt
855 where we collect the old documents and readme texts.
856 2. remove the first part of files where I'm already sure that we no
857 longer need them because of three reasons: either they are just temporary
858 files which were left by Eric or they are preserved original files where
859 I've verified that the diff is also available in the CVS via "cvs diff
860 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
861 the crypto/md/ stuff).
862 [Ralf S. Engelschall]
864 *) More extension code. Incomplete support for subject and issuer alt
865 name, issuer and authority key id. Change the i2v function parameters
866 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
867 what that's for :-) Fix to ASN1 macro which messed up
868 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
871 *) Preliminary support for ENUMERATED type. This is largely copied from the
875 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
876 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
878 *) Make sure `make rehash' target really finds the `openssl' program.
879 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
881 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
882 like to hear about it if this slows down other processors.
885 *) Add CygWin32 platform information to Configure script.
886 [Alan Batie <batie@aahz.jf.intel.com>]
888 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
889 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
891 *) New program nseq to manipulate netscape certificate sequences
894 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
898 *) Fixes to BN code. Previously the default was to define BN_RECURSION
899 but the BN code had some problems that would cause failures when
900 doing certificate verification and some other functions.
901 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
903 *) Add ASN1 and PEM code to support netscape certificate sequences.
906 *) Add ASN1 and PEM code to support netscape certificate sequences.
909 *) Add several PKIX and private extended key usage OIDs.
912 *) Modify the 'ca' program to handle the new extension code. Modify
913 openssl.cnf for new extension format, add comments.
916 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
917 and add a sample to openssl.cnf so req -x509 now adds appropriate
921 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
922 error code, add initial support to X509_print() and x509 application.
925 *) Takes a deep breath and start addding X509 V3 extension support code. Add
926 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
927 stuff is currently isolated and isn't even compiled yet.
930 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
931 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
932 Removed the versions check from X509 routines when loading extensions:
933 this allows certain broken certificates that don't set the version
934 properly to be processed.
937 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
938 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
939 can still be regenerated with "make depend".
942 *) Spelling mistake in C version of CAST-128.
943 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
945 *) Changes to the error generation code. The perl script err-code.pl
946 now reads in the old error codes and retains the old numbers, only
947 adding new ones if necessary. It also only changes the .err files if new
948 codes are added. The makefiles have been modified to only insert errors
949 when needed (to avoid needlessly modifying header files). This is done
950 by only inserting errors if the .err file is newer than the auto generated
951 C file. To rebuild all the error codes from scratch (the old behaviour)
952 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
953 or delete all the .err files.
956 *) CAST-128 was incorrectly implemented for short keys. The C version has
957 been fixed, but is untested. The assembler versions are also fixed, but
958 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
959 to regenerate it if needed.
960 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
961 Hagino <itojun@kame.net>]
963 *) File was opened incorrectly in randfile.c.
964 [Ulf Möller <ulf@fitug.de>]
966 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
967 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
968 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
969 al: it's just almost always a UTCTime. Note this patch adds new error
970 codes so do a "make errors" if there are problems.
973 *) Correct Linux 1 recognition in config.
974 [Ulf Möller <ulf@fitug.de>]
976 *) Remove pointless MD5 hash when using DSA keys in ca.
977 [Anonymous <nobody@replay.com>]
979 *) Generate an error if given an empty string as a cert directory. Also
980 generate an error if handed NULL (previously returned 0 to indicate an
981 error, but didn't set one).
982 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
984 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
987 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
988 parameters. This was causing a warning which killed off the Win32 compile.
991 *) Remove C++ style comments from crypto/bn/bn_local.h.
992 [Neil Costigan <neil.costigan@celocom.com>]
994 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
995 based on a text string, looking up short and long names and finally
996 "dot" format. The "dot" format stuff didn't work. Added new function
997 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
998 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
999 OID is not part of the table.
1002 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1003 X509_LOOKUP_by_alias().
1006 *) Sort openssl functions by name.
1009 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1010 encryption from sample DSA keys (in case anyone is interested the password
1014 *) Make _all_ *_free functions accept a NULL pointer.
1015 [Frans Heymans <fheymans@isaserver.be>]
1017 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1019 [Anonymous <nobody@replay.com>]
1021 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1022 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1024 *) Don't blow it for numeric -newkey arguments to apps/req.
1025 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1027 *) Temp key "for export" tests were wrong in s3_srvr.c.
1028 [Anonymous <nobody@replay.com>]
1030 *) Add prototype for temp key callback functions
1031 SSL_CTX_set_tmp_{rsa,dh}_callback().
1034 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1035 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1038 *) X509_name_add_entry() freed the wrong thing after an error.
1039 [Arne Ansper <arne@ats.cyber.ee>]
1041 *) rsa_eay.c would attempt to free a NULL context.
1042 [Arne Ansper <arne@ats.cyber.ee>]
1044 *) BIO_s_socket() had a broken should_retry() on Windoze.
1045 [Arne Ansper <arne@ats.cyber.ee>]
1047 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1048 [Arne Ansper <arne@ats.cyber.ee>]
1050 *) Make sure the already existing X509_STORE->depth variable is initialized
1051 in X509_STORE_new(), but document the fact that this variable is still
1052 unused in the certificate verification process.
1053 [Ralf S. Engelschall]
1055 *) Fix the various library and apps files to free up pkeys obtained from
1056 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1059 *) Fix reference counting in X509_PUBKEY_get(). This makes
1060 demos/maurice/example2.c work, amongst others, probably.
1061 [Steve Henson and Ben Laurie]
1063 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1064 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1065 are no longer created. This way we have a single and consistent command
1066 line interface `openssl <command>', similar to `cvs <command>'.
1067 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1069 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1070 BIT STRING wrapper always have zero unused bits.
1073 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1076 *) Make the top-level INSTALL documentation easier to understand.
1079 *) Makefiles updated to exit if an error occurs in a sub-directory
1080 make (including if user presses ^C) [Paul Sutton]
1082 *) Make Montgomery context stuff explicit in RSA data structure.
1085 *) Fix build order of pem and err to allow for generated pem.h.
1088 *) Fix renumbering bug in X509_NAME_delete_entry().
1091 *) Enhanced the err-ins.pl script so it makes the error library number
1092 global and can add a library name. This is needed for external ASN1 and
1093 other error libraries.
1096 *) Fixed sk_insert which never worked properly.
1099 *) Fix ASN1 macros so they can handle indefinite length construted
1100 EXPLICIT tags. Some non standard certificates use these: they can now
1104 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1105 into a single doc/ssleay.txt bundle. This way the information is still
1106 preserved but no longer messes up this directory. Now it's new room for
1107 the new set of documenation files.
1108 [Ralf S. Engelschall]
1110 *) SETs were incorrectly DER encoded. This was a major pain, because they
1111 shared code with SEQUENCEs, which aren't coded the same. This means that
1112 almost everything to do with SETs or SEQUENCEs has either changed name or
1113 number of arguments.
1114 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1116 *) Fix test data to work with the above.
1119 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1120 was already fixed by Eric for 0.9.1 it seems.
1121 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1123 *) Autodetect FreeBSD3.
1126 *) Fix various bugs in Configure. This affects the following platforms:
1130 unixware-2.0-pentium
1134 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1135 before they are needed.
1138 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1142 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1144 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1145 changed SSLeay to OpenSSL in version strings.
1146 [Ralf S. Engelschall]
1148 *) Some fixups to the top-level documents.
1151 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1152 because the symlink to include/ was missing.
1153 [Ralf S. Engelschall]
1155 *) Incorporated the popular no-RSA/DSA-only patches
1156 which allow to compile a RSA-free SSLeay.
1157 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1159 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1160 when "ssleay" is still not found.
1161 [Ralf S. Engelschall]
1163 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1164 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1166 *) Updated the README file.
1167 [Ralf S. Engelschall]
1169 *) Added various .cvsignore files in the CVS repository subdirs
1170 to make a "cvs update" really silent.
1171 [Ralf S. Engelschall]
1173 *) Recompiled the error-definition header files and added
1174 missing symbols to the Win32 linker tables.
1175 [Ralf S. Engelschall]
1177 *) Cleaned up the top-level documents;
1178 o new files: CHANGES and LICENSE
1179 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1180 o merged COPYRIGHT into LICENSE
1181 o removed obsolete TODO file
1182 o renamed MICROSOFT to INSTALL.W32
1183 [Ralf S. Engelschall]
1185 *) Removed dummy files from the 0.9.1b source tree:
1186 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1187 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1190 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1191 [Ralf S. Engelschall]
1193 *) Added various platform portability fixes.
1196 *) The Genesis of the OpenSSL rpject:
1197 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1198 Young and Tim J. Hudson created while they were working for C2Net until
1200 [The OpenSSL Project]
1203 Changes between 0.9.0b and 0.9.1b [not released]
1205 *) Updated a few CA certificates under certs/
1208 *) Changed some BIGNUM api stuff.
1211 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1212 DGUX x86, Linux Alpha, etc.
1215 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1216 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1220 *) Add -strparse option to asn1pars program which parses nested
1222 [Dr Stephen Henson <shenson@bigfoot.com>]
1224 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1227 *) DSA fix for "ca" program.
1230 *) Added "-genkey" option to "dsaparam" program.
1233 *) Added RIPE MD160 (rmd160) message digest.
1236 *) Added -a (all) option to "ssleay version" command.
1239 *) Added PLATFORM define which is the id given to Configure.
1242 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1245 *) Extended the ASN.1 parser routines.
1248 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1251 *) Added a BN_CTX to the BN library.
1254 *) Fixed the weak key values in DES library
1257 *) Changed API in EVP library for cipher aliases.
1260 *) Added support for RC2/64bit cipher.
1263 *) Converted the lhash library to the crypto/mem.c functions.
1266 *) Added more recognized ASN.1 object ids.
1269 *) Added more RSA padding checks for SSL/TLS.
1272 *) Added BIO proxy/filter functionality.
1275 *) Added extra_certs to SSL_CTX which can be used
1276 send extra CA certificates to the client in the CA cert chain sending
1277 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1280 *) Now Fortezza is denied in the authentication phase because
1281 this is key exchange mechanism is not supported by SSLeay at all.
1284 *) Additional PKCS1 checks.
1287 *) Support the string "TLSv1" for all TLS v1 ciphers.
1290 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1291 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1294 *) Fixed a few memory leaks.
1297 *) Fixed various code and comment typos.
1300 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1301 bytes sent in the client random.
