6 Changes between 0.9.3a and 0.9.4
8 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
9 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
10 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
11 KEY" because this clashed with PKCS#8 unencrypted string. Since this
12 value was just used as a "magic string" and not used directly its
16 *) Introduce some semblance of const correctness to BN. Shame C doesn't
20 *) "linux-sparc64-gcc" configuration (ultrapenguin).
21 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
23 *) config now generates no-xxx options for missing ciphers.
26 *) Support the EBCDIC character set (work in progress).
27 File ebcdic.c not yet included because it has a different license.
28 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
30 *) Support BS2000/OSD-POSIX.
31 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
33 *) Make callbacks for key generation use void * instead of char *.
36 *) Make S/MIME samples compile (not yet tested).
39 *) Additional typesafe stacks.
42 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
46 Changes between 0.9.3 and 0.9.3a [29 May 1999]
48 *) New configuration variant "sco5-gcc".
50 *) Updated some demos.
51 [Sean O Riordain, Wade Scholine]
53 *) Add missing BIO_free at exit of pkcs12 application.
56 *) Fix memory leak in conf.c.
59 *) Updates for Win32 to assembler version of MD5.
62 *) Set #! path to perl in apps/der_chop to where we found it
63 instead of using a fixed path.
66 *) SHA library changes for irix64-mips4-cc.
69 *) Improvements for VMS support.
73 Changes between 0.9.2b and 0.9.3 [24 May 1999]
75 *) Bignum library bug fix. IRIX 6 passes "make test" now!
76 This also avoids the problems with SC4.2 and unpatched SC5.
77 [Andy Polyakov <appro@fy.chalmers.se>]
79 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
80 These are required because of the typesafe stack would otherwise break
81 existing code. If old code used a structure member which used to be STACK
82 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
83 sk_num or sk_value it would produce an error because the num, data members
84 are not present in STACK_OF. Now it just produces a warning. sk_set
85 replaces the old method of assigning a value to sk_value
86 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
87 that does this will no longer work (and should use sk_set instead) but
88 this could be regarded as a "questionable" behaviour anyway.
91 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
92 correctly handle encrypted S/MIME data.
95 *) Change type of various DES function arguments from des_cblock
96 (which means, in function argument declarations, pointer to char)
97 to des_cblock * (meaning pointer to array with 8 char elements),
98 which allows the compiler to do more typechecking; it was like
99 that back in SSLeay, but with lots of ugly casts.
101 Introduce new type const_des_cblock.
104 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
105 problems: find RecipientInfo structure that matches recipient certificate
106 and initialise the ASN1 structures properly based on passed cipher.
109 *) Belatedly make the BN tests actually check the results.
112 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
113 to and from BNs: it was completely broken. New compilation option
114 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
115 key elements as negative integers.
118 *) Reorganize and speed up MD5.
119 [Andy Polyakov <appro@fy.chalmers.se>]
122 [Richard Levitte <richard@levitte.org>]
124 *) New option -out to asn1parse to allow the parsed structure to be
125 output to a file. This is most useful when combined with the -strparse
126 option to examine the output of things like OCTET STRINGS.
129 *) Make SSL library a little more fool-proof by not requiring any longer
130 that SSL_set_{accept,connect}_state be called before
131 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
132 in many applications because usually everything *appeared* to work as
133 intended anyway -- now it really works as intended).
136 *) Move openssl.cnf out of lib/.
139 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
140 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
141 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
142 [Ralf S. Engelschall]
144 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
145 handle PKCS#7 enveloped data properly.
146 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
148 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
149 copying pointers. The cert_st handling is changed by this in
150 various ways (and thus what used to be known as ctx->default_cert
151 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
152 any longer when s->cert does not give us what we need).
153 ssl_cert_instantiate becomes obsolete by this change.
154 As soon as we've got the new code right (possibly it already is?),
155 we have solved a couple of bugs of the earlier code where s->cert
156 was used as if it could not have been shared with other SSL structures.
158 Note that using the SSL API in certain dirty ways now will result
159 in different behaviour than observed with earlier library versions:
160 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
161 does not influence s as it used to.
163 In order to clean up things more thoroughly, inside SSL_SESSION
164 we don't use CERT any longer, but a new structure SESS_CERT
165 that holds per-session data (if available); currently, this is
166 the peer's certificate chain and, for clients, the server's certificate
167 and temporary key. CERT holds only those values that can have
168 meaningful defaults in an SSL_CTX.
171 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
172 from the internal representation. Various PKCS#7 fixes: remove some
173 evil casts and set the enc_dig_alg field properly based on the signing
177 *) Allow PKCS#12 password to be set from the command line or the
178 environment. Let 'ca' get its config file name from the environment
179 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
183 *) Allow certificate policies extension to use an IA5STRING for the
184 organization field. This is contrary to the PKIX definition but
185 VeriSign uses it and IE5 only recognises this form. Document 'x509'
189 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
190 without disallowing inline assembler and the like for non-pedantic builds.
193 *) Support Borland C++ builder.
194 [Janez Jere <jj@void.si>, modified by Ulf Möller]
199 *) SHA-1 cleanups and performance enhancements.
200 [Andy Polyakov <appro@fy.chalmers.se>]
202 *) Sparc v8plus assembler for the bignum library.
203 [Andy Polyakov <appro@fy.chalmers.se>]
205 *) Accept any -xxx and +xxx compiler options in Configure.
208 *) Update HPUX configuration.
211 *) Add missing sk_<type>_unshift() function to safestack.h
212 [Ralf S. Engelschall]
214 *) New function SSL_CTX_use_certificate_chain_file that sets the
215 "extra_cert"s in addition to the certificate. (This makes sense
216 only for "PEM" format files, as chains as a whole are not
220 *) Support verify_depth from the SSL API.
221 x509_vfy.c had what can be considered an off-by-one-error:
222 Its depth (which was not part of the external interface)
223 was actually counting the number of certificates in a chain;
224 now it really counts the depth.
227 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
228 instead of X509err, which often resulted in confusing error
229 messages since the error codes are not globally unique
230 (e.g. an alleged error in ssl3_accept when a certificate
231 didn't match the private key).
233 *) New function SSL_CTX_set_session_id_context that allows to set a default
234 value (so that you don't need SSL_set_session_id_context for each
235 connection using the SSL_CTX).
238 *) OAEP decoding bug fix.
241 *) Support INSTALL_PREFIX for package builders, as proposed by
245 *) New Configure options "threads" and "no-threads". For systems
246 where the proper compiler options are known (currently Solaris
247 and Linux), "threads" is the default.
250 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
253 *) Install various scripts to $(OPENSSLDIR)/misc, not to
254 $(INSTALLTOP)/bin -- they shouldn't clutter directories
255 such as /usr/local/bin.
258 *) "make linux-shared" to build shared libraries.
259 [Niels Poppe <niels@netbox.org>]
261 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
264 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
265 extension adding in x509 utility.
268 *) Remove NOPROTO sections and error code comments.
271 *) Partial rewrite of the DEF file generator to now parse the ANSI
275 *) New Configure options --prefix=DIR and --openssldir=DIR.
278 *) Complete rewrite of the error code script(s). It is all now handled
279 by one script at the top level which handles error code gathering,
280 header rewriting and C source file generation. It should be much better
281 than the old method: it now uses a modified version of Ulf's parser to
282 read the ANSI prototypes in all header files (thus the old K&R definitions
283 aren't needed for error creation any more) and do a better job of
284 translating function codes into names. The old 'ASN1 error code imbedded
285 in a comment' is no longer necessary and it doesn't use .err files which
286 have now been deleted. Also the error code call doesn't have to appear all
287 on one line (which resulted in some large lines...).
290 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
293 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
294 0 (which usually indicates a closed connection), but continue reading.
297 *) Fix some race conditions.
300 *) Add support for CRL distribution points extension. Add Certificate
301 Policies and CRL distribution points documentation.
304 *) Move the autogenerated header file parts to crypto/opensslconf.h.
307 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
308 8 of keying material. Merlin has also confirmed interop with this fix
309 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
310 [Merlin Hughes <merlin@baltimore.ie>]
312 *) Fix lots of warnings.
313 [Richard Levitte <levitte@stacken.kth.se>]
315 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
316 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
317 [Richard Levitte <levitte@stacken.kth.se>]
319 *) Fix problems with sizeof(long) == 8.
320 [Andy Polyakov <appro@fy.chalmers.se>]
322 *) Change functions to ANSI C.
325 *) Fix typos in error codes.
326 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
328 *) Remove defunct assembler files from Configure.
331 *) SPARC v8 assembler BIGNUM implementation.
332 [Andy Polyakov <appro@fy.chalmers.se>]
334 *) Support for Certificate Policies extension: both print and set.
335 Various additions to support the r2i method this uses.
338 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
339 return a const string when you are expecting an allocated buffer.
342 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
343 types DirectoryString and DisplayText.
346 *) Add code to allow r2i extensions to access the configuration database,
347 add an LHASH database driver and add several ctx helper functions.
350 *) Fix an evil bug in bn_expand2() which caused various BN functions to
351 fail when they extended the size of a BIGNUM.
354 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
355 support typesafe stack.
358 *) Fix typo in SSL_[gs]et_options().
359 [Nils Frostberg <nils@medcom.se>]
361 *) Delete various functions and files that belonged to the (now obsolete)
362 old X509V3 handling code.
365 *) New Configure option "rsaref".
368 *) Don't auto-generate pem.h.
371 *) Introduce type-safe ASN.1 SETs.
374 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
375 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
377 *) Introduce type-safe STACKs. This will almost certainly break lots of code
378 that links with OpenSSL (well at least cause lots of warnings), but fear
379 not: the conversion is trivial, and it eliminates loads of evil casts. A
380 few STACKed things have been converted already. Feel free to convert more.
381 In the fullness of time, I'll do away with the STACK type altogether.
384 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
385 specified in <certfile> by updating the entry in the index.txt file.
386 This way one no longer has to edit the index.txt file manually for
387 revoking a certificate. The -revoke option does the gory details now.
388 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
390 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
391 `-text' option at all and this way the `-noout -text' combination was
392 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
393 [Ralf S. Engelschall]
395 *) Make sure a corresponding plain text error message exists for the
396 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
397 verify callback function determined that a certificate was revoked.
398 [Ralf S. Engelschall]
400 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
401 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
402 all available cipers including rc5, which was forgotten until now.
403 In order to let the testing shell script know which algorithms
404 are available, a new (up to now undocumented) command
405 "openssl list-cipher-commands" is used.
408 *) Bugfix: s_client occasionally would sleep in select() when
409 it should have checked SSL_pending() first.
412 *) New functions DSA_do_sign and DSA_do_verify to provide access to
413 the raw DSA values prior to ASN.1 encoding.
416 *) Tweaks to Configure
417 [Niels Poppe <niels@netbox.org>]
419 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
423 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
426 *) New config option to avoid instructions that are illegal on the 80386.
427 The default code is faster, but requires at least a 486.
430 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
431 SSL2_SERVER_VERSION (not used at all) macros, which are now the
432 same as SSL2_VERSION anyway.
435 *) New "-showcerts" option for s_client.
438 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
439 application. Various cleanups and fixes.
442 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
443 modify error routines to work internally. Add error codes and PBE init
444 to library startup routines.
447 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
448 packing functions to asn1 and evp. Changed function names and error
452 *) PKCS12 integration: and so it begins... First of several patches to
453 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
457 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
458 and display support for Thawte strong extranet extension.
461 *) Add LinuxPPC support.
462 [Jeff Dubrule <igor@pobox.org>]
464 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
465 bn_div_words in alpha.s.
466 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
468 *) Make sure the RSA OAEP test is skipped under -DRSAref because
469 OAEP isn't supported when OpenSSL is built with RSAref.
470 [Ulf Moeller <ulf@fitug.de>]
472 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
473 so they no longer are missing under -DNOPROTO.
474 [Soren S. Jorvang <soren@t.dk>]
477 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
479 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
480 doesn't work when the session is reused. Coming soon!
483 *) Fix a security hole, that allows sessions to be reused in the wrong
484 context thus bypassing client cert protection! All software that uses
485 client certs and session caches in multiple contexts NEEDS PATCHING to
486 allow session reuse! A fuller solution is in the works.
487 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
489 *) Some more source tree cleanups (removed obsolete files
490 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
491 permission on "config" script to be executable) and a fix for the INSTALL
493 [Ulf Moeller <ulf@fitug.de>]
495 *) Remove some legacy and erroneous uses of malloc, free instead of
497 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
499 *) Make rsa_oaep_test return non-zero on error.
500 [Ulf Moeller <ulf@fitug.de>]
502 *) Add support for native Solaris shared libraries. Configure
503 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
504 if someone would make that last step automatic.
505 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
507 *) ctx_size was not built with the right compiler during "make links". Fixed.
510 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
511 except NULL ciphers". This means the default cipher list will no longer
512 enable NULL ciphers. They need to be specifically enabled e.g. with
513 the string "DEFAULT:eNULL".
516 *) Fix to RSA private encryption routines: if p < q then it would
517 occasionally produce an invalid result. This will only happen with
518 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
521 *) Be less restrictive and allow also `perl util/perlpath.pl
522 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
523 because this way one can also use an interpreter named `perl5' (which is
524 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
525 installed as `perl').
526 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
528 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
529 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
531 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
532 advapi32.lib to Win32 build and change the pem test comparision
533 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
534 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
535 and crypto/des/ede_cbcm_enc.c.
538 *) DES quad checksum was broken on big-endian architectures. Fixed.
541 *) Comment out two functions in bio.h that aren't implemented. Fix up the
542 Win32 test batch file so it (might) work again. The Win32 test batch file
543 is horrible: I feel ill....
546 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
547 in e_os.h. Audit of header files to check ANSI and non ANSI
548 sections: 10 functions were absent from non ANSI section and not exported
549 from Windows DLLs. Fixed up libeay.num for new functions.
552 *) Make `openssl version' output lines consistent.
553 [Ralf S. Engelschall]
555 *) Fix Win32 symbol export lists for BIO functions: Added
556 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
557 to ms/libeay{16,32}.def.
558 [Ralf S. Engelschall]
560 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
561 fine under Unix and passes some trivial tests I've now added. But the
562 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
563 added to make sure no one expects that this stuff really works in the
564 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
565 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
567 [Ralf S. Engelschall]
569 *) Fix the generation of two part addresses in perl.
570 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
572 *) Add config entry for Linux on MIPS.
573 [John Tobey <jtobey@channel1.com>]
575 *) Make links whenever Configure is run, unless we are on Windoze.
578 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
579 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
583 *) Add a useful kludge to allow package maintainers to specify compiler and
584 other platforms details on the command line without having to patch the
585 Configure script everytime: One now can use ``perl Configure
586 <id>:<details>'', i.e. platform ids are allowed to have details appended
587 to them (seperated by colons). This is treated as there would be a static
588 pre-configured entry in Configure's %table under key <id> with value
589 <details> and ``perl Configure <id>'' is called. So, when you want to
590 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
591 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
592 now, which overrides the FreeBSD-elf entry on-the-fly.
593 [Ralf S. Engelschall]
595 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
598 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
599 on the `perl Configure ...' command line. This way one can compile
600 OpenSSL libraries with Position Independent Code (PIC) which is needed
601 for linking it into DSOs.
602 [Ralf S. Engelschall]
604 *) Remarkably, export ciphers were totally broken and no-one had noticed!
608 *) Cleaned up the LICENSE document: The official contact for any license
609 questions now is the OpenSSL core team under openssl-core@openssl.org.
610 And add a paragraph about the dual-license situation to make sure people
611 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
612 to the OpenSSL toolkit.
613 [Ralf S. Engelschall]
615 *) General source tree makefile cleanups: Made `making xxx in yyy...'
616 display consistent in the source tree and replaced `/bin/rm' by `rm'.
617 Additonally cleaned up the `make links' target: Remove unnecessary
618 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
619 to speed processing and no longer clutter the display with confusing
620 stuff. Instead only the actually done links are displayed.
621 [Ralf S. Engelschall]
623 *) Permit null encryption ciphersuites, used for authentication only. It used
624 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
625 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
629 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
630 signed attributes when verifying signatures (this would break them),
631 the detached data encoding was wrong and public keys obtained using
632 X509_get_pubkey() weren't freed.
635 *) Add text documentation for the BUFFER functions. Also added a work around
636 to a Win95 console bug. This was triggered by the password read stuff: the
637 last character typed gets carried over to the next fread(). If you were
638 generating a new cert request using 'req' for example then the last
639 character of the passphrase would be CR which would then enter the first
643 *) Added the new `Includes OpenSSL Cryptography Software' button as
644 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
645 button and can be used by applications based on OpenSSL to show the
646 relationship to the OpenSSL project.
647 [Ralf S. Engelschall]
649 *) Remove confusing variables in function signatures in files
650 ssl/ssl_lib.c and ssl/ssl.h.
651 [Lennart Bong <lob@kulthea.stacken.kth.se>]
653 *) Don't install bss_file.c under PREFIX/include/
654 [Lennart Bong <lob@kulthea.stacken.kth.se>]
656 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
657 functions that return function pointers and has support for NT specific
658 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
659 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
660 unsigned to signed types: this was killing the Win32 compile.
663 *) Add new certificate file to stack functions,
664 SSL_add_dir_cert_subjects_to_stack() and
665 SSL_add_file_cert_subjects_to_stack(). These largely supplant
666 SSL_load_client_CA_file(), and can be used to add multiple certs easily
667 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
668 This means that Apache-SSL and similar packages don't have to mess around
669 to add as many CAs as they want to the preferred list.
672 *) Experiment with doxygen documentation. Currently only partially applied to
674 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
675 openssl.doxy as the configuration file.
678 *) Get rid of remaining C++-style comments which strict C compilers hate.
679 [Ralf S. Engelschall, pointed out by Carlos Amengual]
681 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
682 compiled in by default: it has problems with large keys.
685 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
686 DH private keys and/or callback functions which directly correspond to
687 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
688 is needed for applications which have to configure certificates on a
689 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
691 For the RSA certificate situation is makes no difference, but
692 for the DSA certificate situation this fixes the "no shared cipher"
693 problem where the OpenSSL cipher selection procedure failed because the
694 temporary keys were not overtaken from the context and the API provided
695 no way to reconfigure them.
696 The new functions now let applications reconfigure the stuff and they
697 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
698 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
699 non-public-API function ssl_cert_instantiate() is used as a helper
700 function and also to reduce code redundancy inside ssl_rsa.c.
701 [Ralf S. Engelschall]
703 *) Move s_server -dcert and -dkey options out of the undocumented feature
704 area because they are useful for the DSA situation and should be
705 recognized by the users.
706 [Ralf S. Engelschall]
708 *) Fix the cipher decision scheme for export ciphers: the export bits are
709 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
710 SSL_EXP_MASK. So, the original variable has to be used instead of the
711 already masked variable.
712 [Richard Levitte <levitte@stacken.kth.se>]
714 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
715 [Richard Levitte <levitte@stacken.kth.se>]
717 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
718 from `int' to `unsigned int' because it's a length and initialized by
719 EVP_DigestFinal() which expects an `unsigned int *'.
720 [Richard Levitte <levitte@stacken.kth.se>]
722 *) Don't hard-code path to Perl interpreter on shebang line of Configure
723 script. Instead use the usual Shell->Perl transition trick.
724 [Ralf S. Engelschall]
726 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
727 (in addition to RSA certificates) to match the behaviour of `openssl dsa
728 -noout -modulus' as it's already the case for `openssl rsa -noout
729 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
730 currently the public key is printed (a decision which was already done by
731 `openssl dsa -modulus' in the past) which serves a similar purpose.
732 Additionally the NO_RSA no longer completely removes the whole -modulus
733 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
735 [Ralf S. Engelschall]
737 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
738 BIO. See the source (crypto/evp/bio_ok.c) for more info.
739 [Arne Ansper <arne@ats.cyber.ee>]
741 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
742 to be added. Now both 'req' and 'ca' can use new objects defined in the
746 *) Add cool BIO that does syslog (or event log on NT).
747 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
749 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
750 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
751 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
752 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
755 *) Add preliminary config info for new extension code.
758 *) Make RSA_NO_PADDING really use no padding.
759 [Ulf Moeller <ulf@fitug.de>]
761 *) Generate errors when private/public key check is done.
764 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
765 for some CRL extensions and new objects added.
768 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
769 key usage extension and fuller support for authority key id.
772 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
773 padding method for RSA, which is recommended for new applications in PKCS
774 #1 v2.0 (RFC 2437, October 1998).
775 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
776 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
777 against Bleichbacher's attack on RSA.
778 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
781 *) Updates to the new SSL compression code
782 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
784 *) Fix so that the version number in the master secret, when passed
785 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
786 (because the server will not accept higher), that the version number
787 is 0x03,0x01, not 0x03,0x00
788 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
790 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
791 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
792 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
795 *) Support for RAW extensions where an arbitrary extension can be
796 created by including its DER encoding. See apps/openssl.cnf for
800 *) Make sure latest Perl versions don't interpret some generated C array
801 code as Perl array code in the crypto/err/err_genc.pl script.
802 [Lars Weber <3weber@informatik.uni-hamburg.de>]
804 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
805 not many people have the assembler. Various Win32 compilation fixes and
806 update to the INSTALL.W32 file with (hopefully) more accurate Win32
810 *) Modify configure script 'Configure' to automatically create crypto/date.h
811 file under Win32 and also build pem.h from pem.org. New script
812 util/mkfiles.pl to create the MINFO file on environments that can't do a
813 'make files': perl util/mkfiles.pl >MINFO should work.
816 *) Major rework of DES function declarations, in the pursuit of correctness
817 and purity. As a result, many evil casts evaporated, and some weirdness,
818 too. You may find this causes warnings in your code. Zapping your evil
819 casts will probably fix them. Mostly.
822 *) Fix for a typo in asn1.h. Bug fix to object creation script
823 obj_dat.pl. It considered a zero in an object definition to mean
824 "end of object": none of the objects in objects.h have any zeros
825 so it wasn't spotted.
826 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
828 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
829 Masking (CBCM). In the absence of test vectors, the best I have been able
830 to do is check that the decrypt undoes the encrypt, so far. Send me test
831 vectors if you have them.
834 *) Correct calculation of key length for export ciphers (too much space was
835 allocated for null ciphers). This has not been tested!
838 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
839 message is now correct (it understands "crypto" and "ssl" on its
840 command line). There is also now an "update" option. This will update
841 the util/ssleay.num and util/libeay.num files with any new functions.
843 perl util/mkdef.pl crypto ssl update
847 *) Overhauled the Perl interface (perl/*):
848 - ported BN stuff to OpenSSL's different BN library
849 - made the perl/ source tree CVS-aware
850 - renamed the package from SSLeay to OpenSSL (the files still contain
851 their history because I've copied them in the repository)
852 - removed obsolete files (the test scripts will be replaced
853 by better Test::Harness variants in the future)
854 [Ralf S. Engelschall]
856 *) First cut for a very conservative source tree cleanup:
857 1. merge various obsolete readme texts into doc/ssleay.txt
858 where we collect the old documents and readme texts.
859 2. remove the first part of files where I'm already sure that we no
860 longer need them because of three reasons: either they are just temporary
861 files which were left by Eric or they are preserved original files where
862 I've verified that the diff is also available in the CVS via "cvs diff
863 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
864 the crypto/md/ stuff).
865 [Ralf S. Engelschall]
867 *) More extension code. Incomplete support for subject and issuer alt
868 name, issuer and authority key id. Change the i2v function parameters
869 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
870 what that's for :-) Fix to ASN1 macro which messed up
871 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
874 *) Preliminary support for ENUMERATED type. This is largely copied from the
878 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
879 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
881 *) Make sure `make rehash' target really finds the `openssl' program.
882 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
884 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
885 like to hear about it if this slows down other processors.
888 *) Add CygWin32 platform information to Configure script.
889 [Alan Batie <batie@aahz.jf.intel.com>]
891 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
892 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
894 *) New program nseq to manipulate netscape certificate sequences
897 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
901 *) Fixes to BN code. Previously the default was to define BN_RECURSION
902 but the BN code had some problems that would cause failures when
903 doing certificate verification and some other functions.
904 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
906 *) Add ASN1 and PEM code to support netscape certificate sequences.
909 *) Add ASN1 and PEM code to support netscape certificate sequences.
912 *) Add several PKIX and private extended key usage OIDs.
915 *) Modify the 'ca' program to handle the new extension code. Modify
916 openssl.cnf for new extension format, add comments.
919 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
920 and add a sample to openssl.cnf so req -x509 now adds appropriate
924 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
925 error code, add initial support to X509_print() and x509 application.
928 *) Takes a deep breath and start addding X509 V3 extension support code. Add
929 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
930 stuff is currently isolated and isn't even compiled yet.
933 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
934 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
935 Removed the versions check from X509 routines when loading extensions:
936 this allows certain broken certificates that don't set the version
937 properly to be processed.
940 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
941 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
942 can still be regenerated with "make depend".
945 *) Spelling mistake in C version of CAST-128.
946 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
948 *) Changes to the error generation code. The perl script err-code.pl
949 now reads in the old error codes and retains the old numbers, only
950 adding new ones if necessary. It also only changes the .err files if new
951 codes are added. The makefiles have been modified to only insert errors
952 when needed (to avoid needlessly modifying header files). This is done
953 by only inserting errors if the .err file is newer than the auto generated
954 C file. To rebuild all the error codes from scratch (the old behaviour)
955 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
956 or delete all the .err files.
959 *) CAST-128 was incorrectly implemented for short keys. The C version has
960 been fixed, but is untested. The assembler versions are also fixed, but
961 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
962 to regenerate it if needed.
963 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
964 Hagino <itojun@kame.net>]
966 *) File was opened incorrectly in randfile.c.
967 [Ulf Möller <ulf@fitug.de>]
969 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
970 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
971 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
972 al: it's just almost always a UTCTime. Note this patch adds new error
973 codes so do a "make errors" if there are problems.
976 *) Correct Linux 1 recognition in config.
977 [Ulf Möller <ulf@fitug.de>]
979 *) Remove pointless MD5 hash when using DSA keys in ca.
980 [Anonymous <nobody@replay.com>]
982 *) Generate an error if given an empty string as a cert directory. Also
983 generate an error if handed NULL (previously returned 0 to indicate an
984 error, but didn't set one).
985 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
987 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
990 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
991 parameters. This was causing a warning which killed off the Win32 compile.
994 *) Remove C++ style comments from crypto/bn/bn_local.h.
995 [Neil Costigan <neil.costigan@celocom.com>]
997 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
998 based on a text string, looking up short and long names and finally
999 "dot" format. The "dot" format stuff didn't work. Added new function
1000 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1001 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1002 OID is not part of the table.
1005 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1006 X509_LOOKUP_by_alias().
1009 *) Sort openssl functions by name.
1012 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1013 encryption from sample DSA keys (in case anyone is interested the password
1017 *) Make _all_ *_free functions accept a NULL pointer.
1018 [Frans Heymans <fheymans@isaserver.be>]
1020 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1022 [Anonymous <nobody@replay.com>]
1024 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1025 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1027 *) Don't blow it for numeric -newkey arguments to apps/req.
1028 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1030 *) Temp key "for export" tests were wrong in s3_srvr.c.
1031 [Anonymous <nobody@replay.com>]
1033 *) Add prototype for temp key callback functions
1034 SSL_CTX_set_tmp_{rsa,dh}_callback().
1037 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1038 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1041 *) X509_name_add_entry() freed the wrong thing after an error.
1042 [Arne Ansper <arne@ats.cyber.ee>]
1044 *) rsa_eay.c would attempt to free a NULL context.
1045 [Arne Ansper <arne@ats.cyber.ee>]
1047 *) BIO_s_socket() had a broken should_retry() on Windoze.
1048 [Arne Ansper <arne@ats.cyber.ee>]
1050 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1051 [Arne Ansper <arne@ats.cyber.ee>]
1053 *) Make sure the already existing X509_STORE->depth variable is initialized
1054 in X509_STORE_new(), but document the fact that this variable is still
1055 unused in the certificate verification process.
1056 [Ralf S. Engelschall]
1058 *) Fix the various library and apps files to free up pkeys obtained from
1059 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1062 *) Fix reference counting in X509_PUBKEY_get(). This makes
1063 demos/maurice/example2.c work, amongst others, probably.
1064 [Steve Henson and Ben Laurie]
1066 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1067 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1068 are no longer created. This way we have a single and consistent command
1069 line interface `openssl <command>', similar to `cvs <command>'.
1070 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1072 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1073 BIT STRING wrapper always have zero unused bits.
1076 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1079 *) Make the top-level INSTALL documentation easier to understand.
1082 *) Makefiles updated to exit if an error occurs in a sub-directory
1083 make (including if user presses ^C) [Paul Sutton]
1085 *) Make Montgomery context stuff explicit in RSA data structure.
1088 *) Fix build order of pem and err to allow for generated pem.h.
1091 *) Fix renumbering bug in X509_NAME_delete_entry().
1094 *) Enhanced the err-ins.pl script so it makes the error library number
1095 global and can add a library name. This is needed for external ASN1 and
1096 other error libraries.
1099 *) Fixed sk_insert which never worked properly.
1102 *) Fix ASN1 macros so they can handle indefinite length construted
1103 EXPLICIT tags. Some non standard certificates use these: they can now
1107 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1108 into a single doc/ssleay.txt bundle. This way the information is still
1109 preserved but no longer messes up this directory. Now it's new room for
1110 the new set of documenation files.
1111 [Ralf S. Engelschall]
1113 *) SETs were incorrectly DER encoded. This was a major pain, because they
1114 shared code with SEQUENCEs, which aren't coded the same. This means that
1115 almost everything to do with SETs or SEQUENCEs has either changed name or
1116 number of arguments.
1117 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1119 *) Fix test data to work with the above.
1122 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1123 was already fixed by Eric for 0.9.1 it seems.
1124 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1126 *) Autodetect FreeBSD3.
1129 *) Fix various bugs in Configure. This affects the following platforms:
1133 unixware-2.0-pentium
1137 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1138 before they are needed.
1141 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1145 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1147 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1148 changed SSLeay to OpenSSL in version strings.
1149 [Ralf S. Engelschall]
1151 *) Some fixups to the top-level documents.
1154 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1155 because the symlink to include/ was missing.
1156 [Ralf S. Engelschall]
1158 *) Incorporated the popular no-RSA/DSA-only patches
1159 which allow to compile a RSA-free SSLeay.
1160 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1162 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1163 when "ssleay" is still not found.
1164 [Ralf S. Engelschall]
1166 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1167 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1169 *) Updated the README file.
1170 [Ralf S. Engelschall]
1172 *) Added various .cvsignore files in the CVS repository subdirs
1173 to make a "cvs update" really silent.
1174 [Ralf S. Engelschall]
1176 *) Recompiled the error-definition header files and added
1177 missing symbols to the Win32 linker tables.
1178 [Ralf S. Engelschall]
1180 *) Cleaned up the top-level documents;
1181 o new files: CHANGES and LICENSE
1182 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1183 o merged COPYRIGHT into LICENSE
1184 o removed obsolete TODO file
1185 o renamed MICROSOFT to INSTALL.W32
1186 [Ralf S. Engelschall]
1188 *) Removed dummy files from the 0.9.1b source tree:
1189 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1190 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
1191 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
1192 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
1193 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1194 [Ralf S. Engelschall]
1196 *) Added various platform portability fixes.
1199 *) The Genesis of the OpenSSL rpject:
1200 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1201 Young and Tim J. Hudson created while they were working for C2Net until
1203 [The OpenSSL Project]
1206 Changes between 0.9.0b and 0.9.1b [not released]
1208 *) Updated a few CA certificates under certs/
1211 *) Changed some BIGNUM api stuff.
1214 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1215 DGUX x86, Linux Alpha, etc.
1218 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1219 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1223 *) Add -strparse option to asn1pars program which parses nested
1225 [Dr Stephen Henson <shenson@bigfoot.com>]
1227 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1230 *) DSA fix for "ca" program.
1233 *) Added "-genkey" option to "dsaparam" program.
1236 *) Added RIPE MD160 (rmd160) message digest.
1239 *) Added -a (all) option to "ssleay version" command.
1242 *) Added PLATFORM define which is the id given to Configure.
1245 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1248 *) Extended the ASN.1 parser routines.
1251 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1254 *) Added a BN_CTX to the BN library.
1257 *) Fixed the weak key values in DES library
1260 *) Changed API in EVP library for cipher aliases.
1263 *) Added support for RC2/64bit cipher.
1266 *) Converted the lhash library to the crypto/mem.c functions.
1269 *) Added more recognized ASN.1 object ids.
1272 *) Added more RSA padding checks for SSL/TLS.
1275 *) Added BIO proxy/filter functionality.
1278 *) Added extra_certs to SSL_CTX which can be used
1279 send extra CA certificates to the client in the CA cert chain sending
1280 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1283 *) Now Fortezza is denied in the authentication phase because
1284 this is key exchange mechanism is not supported by SSLeay at all.
1287 *) Additional PKCS1 checks.
1290 *) Support the string "TLSv1" for all TLS v1 ciphers.
1293 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1294 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
