6 Changes between 0.9.3a and 0.9.4
8 *) Introduce some semblance of const correctness to BN. Shame C doesn't
12 *) "linux-sparc64-gcc" configuration (ultrapenguin).
13 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
15 *) config now generates no-xxx options for missing ciphers.
18 *) Support the EBCDIC character set (work in progress).
19 File ebcdic.c not yet included because it has a different license.
20 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
22 *) Support BS2000/OSD-POSIX.
23 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
25 *) Make callbacks for key generation use void * instead of char *.
28 *) Make S/MIME samples compile (not yet tested).
31 *) Additional typesafe stacks.
34 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
38 Changes between 0.9.3 and 0.9.3a [29 May 1999]
40 *) New configuration variant "sco5-gcc".
42 *) Updated some demos.
43 [Sean O Riordain, Wade Scholine]
45 *) Add missing BIO_free at exit of pkcs12 application.
48 *) Fix memory leak in conf.c.
51 *) Updates for Win32 to assembler version of MD5.
54 *) Set #! path to perl in apps/der_chop to where we found it
55 instead of using a fixed path.
58 *) SHA library changes for irix64-mips4-cc.
61 *) Improvements for VMS support.
65 Changes between 0.9.2b and 0.9.3 [24 May 1999]
67 *) Bignum library bug fix. IRIX 6 passes "make test" now!
68 This also avoids the problems with SC4.2 and unpatched SC5.
69 [Andy Polyakov <appro@fy.chalmers.se>]
71 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
72 These are required because of the typesafe stack would otherwise break
73 existing code. If old code used a structure member which used to be STACK
74 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
75 sk_num or sk_value it would produce an error because the num, data members
76 are not present in STACK_OF. Now it just produces a warning. sk_set
77 replaces the old method of assigning a value to sk_value
78 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
79 that does this will no longer work (and should use sk_set instead) but
80 this could be regarded as a "questionable" behaviour anyway.
83 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
84 correctly handle encrypted S/MIME data.
87 *) Change type of various DES function arguments from des_cblock
88 (which means, in function argument declarations, pointer to char)
89 to des_cblock * (meaning pointer to array with 8 char elements),
90 which allows the compiler to do more typechecking; it was like
91 that back in SSLeay, but with lots of ugly casts.
93 Introduce new type const_des_cblock.
96 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
97 problems: find RecipientInfo structure that matches recipient certificate
98 and initialise the ASN1 structures properly based on passed cipher.
101 *) Belatedly make the BN tests actually check the results.
104 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
105 to and from BNs: it was completely broken. New compilation option
106 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
107 key elements as negative integers.
110 *) Reorganize and speed up MD5.
111 [Andy Polyakov <appro@fy.chalmers.se>]
114 [Richard Levitte <richard@levitte.org>]
116 *) New option -out to asn1parse to allow the parsed structure to be
117 output to a file. This is most useful when combined with the -strparse
118 option to examine the output of things like OCTET STRINGS.
121 *) Make SSL library a little more fool-proof by not requiring any longer
122 that SSL_set_{accept,connect}_state be called before
123 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
124 in many applications because usually everything *appeared* to work as
125 intended anyway -- now it really works as intended).
128 *) Move openssl.cnf out of lib/.
131 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
132 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
133 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
134 [Ralf S. Engelschall]
136 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
137 handle PKCS#7 enveloped data properly.
138 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
140 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
141 copying pointers. The cert_st handling is changed by this in
142 various ways (and thus what used to be known as ctx->default_cert
143 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
144 any longer when s->cert does not give us what we need).
145 ssl_cert_instantiate becomes obsolete by this change.
146 As soon as we've got the new code right (possibly it already is?),
147 we have solved a couple of bugs of the earlier code where s->cert
148 was used as if it could not have been shared with other SSL structures.
150 Note that using the SSL API in certain dirty ways now will result
151 in different behaviour than observed with earlier library versions:
152 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
153 does not influence s as it used to.
155 In order to clean up things more thoroughly, inside SSL_SESSION
156 we don't use CERT any longer, but a new structure SESS_CERT
157 that holds per-session data (if available); currently, this is
158 the peer's certificate chain and, for clients, the server's certificate
159 and temporary key. CERT holds only those values that can have
160 meaningful defaults in an SSL_CTX.
163 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
164 from the internal representation. Various PKCS#7 fixes: remove some
165 evil casts and set the enc_dig_alg field properly based on the signing
169 *) Allow PKCS#12 password to be set from the command line or the
170 environment. Let 'ca' get its config file name from the environment
171 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
175 *) Allow certificate policies extension to use an IA5STRING for the
176 organization field. This is contrary to the PKIX definition but
177 VeriSign uses it and IE5 only recognises this form. Document 'x509'
181 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
182 without disallowing inline assembler and the like for non-pedantic builds.
185 *) Support Borland C++ builder.
186 [Janez Jere <jj@void.si>, modified by Ulf Möller]
191 *) SHA-1 cleanups and performance enhancements.
192 [Andy Polyakov <appro@fy.chalmers.se>]
194 *) Sparc v8plus assembler for the bignum library.
195 [Andy Polyakov <appro@fy.chalmers.se>]
197 *) Accept any -xxx and +xxx compiler options in Configure.
200 *) Update HPUX configuration.
203 *) Add missing sk_<type>_unshift() function to safestack.h
204 [Ralf S. Engelschall]
206 *) New function SSL_CTX_use_certificate_chain_file that sets the
207 "extra_cert"s in addition to the certificate. (This makes sense
208 only for "PEM" format files, as chains as a whole are not
212 *) Support verify_depth from the SSL API.
213 x509_vfy.c had what can be considered an off-by-one-error:
214 Its depth (which was not part of the external interface)
215 was actually counting the number of certificates in a chain;
216 now it really counts the depth.
219 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
220 instead of X509err, which often resulted in confusing error
221 messages since the error codes are not globally unique
222 (e.g. an alleged error in ssl3_accept when a certificate
223 didn't match the private key).
225 *) New function SSL_CTX_set_session_id_context that allows to set a default
226 value (so that you don't need SSL_set_session_id_context for each
227 connection using the SSL_CTX).
230 *) OAEP decoding bug fix.
233 *) Support INSTALL_PREFIX for package builders, as proposed by
237 *) New Configure options "threads" and "no-threads". For systems
238 where the proper compiler options are known (currently Solaris
239 and Linux), "threads" is the default.
242 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
245 *) Install various scripts to $(OPENSSLDIR)/misc, not to
246 $(INSTALLTOP)/bin -- they shouldn't clutter directories
247 such as /usr/local/bin.
250 *) "make linux-shared" to build shared libraries.
251 [Niels Poppe <niels@netbox.org>]
253 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
256 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
257 extension adding in x509 utility.
260 *) Remove NOPROTO sections and error code comments.
263 *) Partial rewrite of the DEF file generator to now parse the ANSI
267 *) New Configure options --prefix=DIR and --openssldir=DIR.
270 *) Complete rewrite of the error code script(s). It is all now handled
271 by one script at the top level which handles error code gathering,
272 header rewriting and C source file generation. It should be much better
273 than the old method: it now uses a modified version of Ulf's parser to
274 read the ANSI prototypes in all header files (thus the old K&R definitions
275 aren't needed for error creation any more) and do a better job of
276 translating function codes into names. The old 'ASN1 error code imbedded
277 in a comment' is no longer necessary and it doesn't use .err files which
278 have now been deleted. Also the error code call doesn't have to appear all
279 on one line (which resulted in some large lines...).
282 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
285 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
286 0 (which usually indicates a closed connection), but continue reading.
289 *) Fix some race conditions.
292 *) Add support for CRL distribution points extension. Add Certificate
293 Policies and CRL distribution points documentation.
296 *) Move the autogenerated header file parts to crypto/opensslconf.h.
299 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
300 8 of keying material. Merlin has also confirmed interop with this fix
301 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
302 [Merlin Hughes <merlin@baltimore.ie>]
304 *) Fix lots of warnings.
305 [Richard Levitte <levitte@stacken.kth.se>]
307 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
308 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
309 [Richard Levitte <levitte@stacken.kth.se>]
311 *) Fix problems with sizeof(long) == 8.
312 [Andy Polyakov <appro@fy.chalmers.se>]
314 *) Change functions to ANSI C.
317 *) Fix typos in error codes.
318 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
320 *) Remove defunct assembler files from Configure.
323 *) SPARC v8 assembler BIGNUM implementation.
324 [Andy Polyakov <appro@fy.chalmers.se>]
326 *) Support for Certificate Policies extension: both print and set.
327 Various additions to support the r2i method this uses.
330 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
331 return a const string when you are expecting an allocated buffer.
334 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
335 types DirectoryString and DisplayText.
338 *) Add code to allow r2i extensions to access the configuration database,
339 add an LHASH database driver and add several ctx helper functions.
342 *) Fix an evil bug in bn_expand2() which caused various BN functions to
343 fail when they extended the size of a BIGNUM.
346 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
347 support typesafe stack.
350 *) Fix typo in SSL_[gs]et_options().
351 [Nils Frostberg <nils@medcom.se>]
353 *) Delete various functions and files that belonged to the (now obsolete)
354 old X509V3 handling code.
357 *) New Configure option "rsaref".
360 *) Don't auto-generate pem.h.
363 *) Introduce type-safe ASN.1 SETs.
366 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
367 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
369 *) Introduce type-safe STACKs. This will almost certainly break lots of code
370 that links with OpenSSL (well at least cause lots of warnings), but fear
371 not: the conversion is trivial, and it eliminates loads of evil casts. A
372 few STACKed things have been converted already. Feel free to convert more.
373 In the fullness of time, I'll do away with the STACK type altogether.
376 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
377 specified in <certfile> by updating the entry in the index.txt file.
378 This way one no longer has to edit the index.txt file manually for
379 revoking a certificate. The -revoke option does the gory details now.
380 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
382 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
383 `-text' option at all and this way the `-noout -text' combination was
384 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
385 [Ralf S. Engelschall]
387 *) Make sure a corresponding plain text error message exists for the
388 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
389 verify callback function determined that a certificate was revoked.
390 [Ralf S. Engelschall]
392 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
393 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
394 all available cipers including rc5, which was forgotten until now.
395 In order to let the testing shell script know which algorithms
396 are available, a new (up to now undocumented) command
397 "openssl list-cipher-commands" is used.
400 *) Bugfix: s_client occasionally would sleep in select() when
401 it should have checked SSL_pending() first.
404 *) New functions DSA_do_sign and DSA_do_verify to provide access to
405 the raw DSA values prior to ASN.1 encoding.
408 *) Tweaks to Configure
409 [Niels Poppe <niels@netbox.org>]
411 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
415 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
418 *) New config option to avoid instructions that are illegal on the 80386.
419 The default code is faster, but requires at least a 486.
422 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
423 SSL2_SERVER_VERSION (not used at all) macros, which are now the
424 same as SSL2_VERSION anyway.
427 *) New "-showcerts" option for s_client.
430 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
431 application. Various cleanups and fixes.
434 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
435 modify error routines to work internally. Add error codes and PBE init
436 to library startup routines.
439 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
440 packing functions to asn1 and evp. Changed function names and error
444 *) PKCS12 integration: and so it begins... First of several patches to
445 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
449 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
450 and display support for Thawte strong extranet extension.
453 *) Add LinuxPPC support.
454 [Jeff Dubrule <igor@pobox.org>]
456 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
457 bn_div_words in alpha.s.
458 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
460 *) Make sure the RSA OAEP test is skipped under -DRSAref because
461 OAEP isn't supported when OpenSSL is built with RSAref.
462 [Ulf Moeller <ulf@fitug.de>]
464 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
465 so they no longer are missing under -DNOPROTO.
466 [Soren S. Jorvang <soren@t.dk>]
469 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
471 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
472 doesn't work when the session is reused. Coming soon!
475 *) Fix a security hole, that allows sessions to be reused in the wrong
476 context thus bypassing client cert protection! All software that uses
477 client certs and session caches in multiple contexts NEEDS PATCHING to
478 allow session reuse! A fuller solution is in the works.
479 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
481 *) Some more source tree cleanups (removed obsolete files
482 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
483 permission on "config" script to be executable) and a fix for the INSTALL
485 [Ulf Moeller <ulf@fitug.de>]
487 *) Remove some legacy and erroneous uses of malloc, free instead of
489 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
491 *) Make rsa_oaep_test return non-zero on error.
492 [Ulf Moeller <ulf@fitug.de>]
494 *) Add support for native Solaris shared libraries. Configure
495 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
496 if someone would make that last step automatic.
497 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
499 *) ctx_size was not built with the right compiler during "make links". Fixed.
502 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
503 except NULL ciphers". This means the default cipher list will no longer
504 enable NULL ciphers. They need to be specifically enabled e.g. with
505 the string "DEFAULT:eNULL".
508 *) Fix to RSA private encryption routines: if p < q then it would
509 occasionally produce an invalid result. This will only happen with
510 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
513 *) Be less restrictive and allow also `perl util/perlpath.pl
514 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
515 because this way one can also use an interpreter named `perl5' (which is
516 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
517 installed as `perl').
518 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
520 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
521 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
523 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
524 advapi32.lib to Win32 build and change the pem test comparision
525 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
526 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
527 and crypto/des/ede_cbcm_enc.c.
530 *) DES quad checksum was broken on big-endian architectures. Fixed.
533 *) Comment out two functions in bio.h that aren't implemented. Fix up the
534 Win32 test batch file so it (might) work again. The Win32 test batch file
535 is horrible: I feel ill....
538 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
539 in e_os.h. Audit of header files to check ANSI and non ANSI
540 sections: 10 functions were absent from non ANSI section and not exported
541 from Windows DLLs. Fixed up libeay.num for new functions.
544 *) Make `openssl version' output lines consistent.
545 [Ralf S. Engelschall]
547 *) Fix Win32 symbol export lists for BIO functions: Added
548 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
549 to ms/libeay{16,32}.def.
550 [Ralf S. Engelschall]
552 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
553 fine under Unix and passes some trivial tests I've now added. But the
554 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
555 added to make sure no one expects that this stuff really works in the
556 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
557 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
559 [Ralf S. Engelschall]
561 *) Fix the generation of two part addresses in perl.
562 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
564 *) Add config entry for Linux on MIPS.
565 [John Tobey <jtobey@channel1.com>]
567 *) Make links whenever Configure is run, unless we are on Windoze.
570 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
571 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
575 *) Add a useful kludge to allow package maintainers to specify compiler and
576 other platforms details on the command line without having to patch the
577 Configure script everytime: One now can use ``perl Configure
578 <id>:<details>'', i.e. platform ids are allowed to have details appended
579 to them (seperated by colons). This is treated as there would be a static
580 pre-configured entry in Configure's %table under key <id> with value
581 <details> and ``perl Configure <id>'' is called. So, when you want to
582 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
583 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
584 now, which overrides the FreeBSD-elf entry on-the-fly.
585 [Ralf S. Engelschall]
587 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
590 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
591 on the `perl Configure ...' command line. This way one can compile
592 OpenSSL libraries with Position Independent Code (PIC) which is needed
593 for linking it into DSOs.
594 [Ralf S. Engelschall]
596 *) Remarkably, export ciphers were totally broken and no-one had noticed!
600 *) Cleaned up the LICENSE document: The official contact for any license
601 questions now is the OpenSSL core team under openssl-core@openssl.org.
602 And add a paragraph about the dual-license situation to make sure people
603 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
604 to the OpenSSL toolkit.
605 [Ralf S. Engelschall]
607 *) General source tree makefile cleanups: Made `making xxx in yyy...'
608 display consistent in the source tree and replaced `/bin/rm' by `rm'.
609 Additonally cleaned up the `make links' target: Remove unnecessary
610 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
611 to speed processing and no longer clutter the display with confusing
612 stuff. Instead only the actually done links are displayed.
613 [Ralf S. Engelschall]
615 *) Permit null encryption ciphersuites, used for authentication only. It used
616 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
617 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
621 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
622 signed attributes when verifying signatures (this would break them),
623 the detached data encoding was wrong and public keys obtained using
624 X509_get_pubkey() weren't freed.
627 *) Add text documentation for the BUFFER functions. Also added a work around
628 to a Win95 console bug. This was triggered by the password read stuff: the
629 last character typed gets carried over to the next fread(). If you were
630 generating a new cert request using 'req' for example then the last
631 character of the passphrase would be CR which would then enter the first
635 *) Added the new `Includes OpenSSL Cryptography Software' button as
636 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
637 button and can be used by applications based on OpenSSL to show the
638 relationship to the OpenSSL project.
639 [Ralf S. Engelschall]
641 *) Remove confusing variables in function signatures in files
642 ssl/ssl_lib.c and ssl/ssl.h.
643 [Lennart Bong <lob@kulthea.stacken.kth.se>]
645 *) Don't install bss_file.c under PREFIX/include/
646 [Lennart Bong <lob@kulthea.stacken.kth.se>]
648 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
649 functions that return function pointers and has support for NT specific
650 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
651 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
652 unsigned to signed types: this was killing the Win32 compile.
655 *) Add new certificate file to stack functions,
656 SSL_add_dir_cert_subjects_to_stack() and
657 SSL_add_file_cert_subjects_to_stack(). These largely supplant
658 SSL_load_client_CA_file(), and can be used to add multiple certs easily
659 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
660 This means that Apache-SSL and similar packages don't have to mess around
661 to add as many CAs as they want to the preferred list.
664 *) Experiment with doxygen documentation. Currently only partially applied to
666 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
667 openssl.doxy as the configuration file.
670 *) Get rid of remaining C++-style comments which strict C compilers hate.
671 [Ralf S. Engelschall, pointed out by Carlos Amengual]
673 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
674 compiled in by default: it has problems with large keys.
677 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
678 DH private keys and/or callback functions which directly correspond to
679 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
680 is needed for applications which have to configure certificates on a
681 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
683 For the RSA certificate situation is makes no difference, but
684 for the DSA certificate situation this fixes the "no shared cipher"
685 problem where the OpenSSL cipher selection procedure failed because the
686 temporary keys were not overtaken from the context and the API provided
687 no way to reconfigure them.
688 The new functions now let applications reconfigure the stuff and they
689 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
690 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
691 non-public-API function ssl_cert_instantiate() is used as a helper
692 function and also to reduce code redundancy inside ssl_rsa.c.
693 [Ralf S. Engelschall]
695 *) Move s_server -dcert and -dkey options out of the undocumented feature
696 area because they are useful for the DSA situation and should be
697 recognized by the users.
698 [Ralf S. Engelschall]
700 *) Fix the cipher decision scheme for export ciphers: the export bits are
701 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
702 SSL_EXP_MASK. So, the original variable has to be used instead of the
703 already masked variable.
704 [Richard Levitte <levitte@stacken.kth.se>]
706 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
707 [Richard Levitte <levitte@stacken.kth.se>]
709 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
710 from `int' to `unsigned int' because it's a length and initialized by
711 EVP_DigestFinal() which expects an `unsigned int *'.
712 [Richard Levitte <levitte@stacken.kth.se>]
714 *) Don't hard-code path to Perl interpreter on shebang line of Configure
715 script. Instead use the usual Shell->Perl transition trick.
716 [Ralf S. Engelschall]
718 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
719 (in addition to RSA certificates) to match the behaviour of `openssl dsa
720 -noout -modulus' as it's already the case for `openssl rsa -noout
721 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
722 currently the public key is printed (a decision which was already done by
723 `openssl dsa -modulus' in the past) which serves a similar purpose.
724 Additionally the NO_RSA no longer completely removes the whole -modulus
725 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
727 [Ralf S. Engelschall]
729 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
730 BIO. See the source (crypto/evp/bio_ok.c) for more info.
731 [Arne Ansper <arne@ats.cyber.ee>]
733 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
734 to be added. Now both 'req' and 'ca' can use new objects defined in the
738 *) Add cool BIO that does syslog (or event log on NT).
739 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
741 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
742 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
743 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
744 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
747 *) Add preliminary config info for new extension code.
750 *) Make RSA_NO_PADDING really use no padding.
751 [Ulf Moeller <ulf@fitug.de>]
753 *) Generate errors when private/public key check is done.
756 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
757 for some CRL extensions and new objects added.
760 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
761 key usage extension and fuller support for authority key id.
764 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
765 padding method for RSA, which is recommended for new applications in PKCS
766 #1 v2.0 (RFC 2437, October 1998).
767 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
768 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
769 against Bleichbacher's attack on RSA.
770 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
773 *) Updates to the new SSL compression code
774 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
776 *) Fix so that the version number in the master secret, when passed
777 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
778 (because the server will not accept higher), that the version number
779 is 0x03,0x01, not 0x03,0x00
780 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
782 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
783 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
784 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
787 *) Support for RAW extensions where an arbitrary extension can be
788 created by including its DER encoding. See apps/openssl.cnf for
792 *) Make sure latest Perl versions don't interpret some generated C array
793 code as Perl array code in the crypto/err/err_genc.pl script.
794 [Lars Weber <3weber@informatik.uni-hamburg.de>]
796 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
797 not many people have the assembler. Various Win32 compilation fixes and
798 update to the INSTALL.W32 file with (hopefully) more accurate Win32
802 *) Modify configure script 'Configure' to automatically create crypto/date.h
803 file under Win32 and also build pem.h from pem.org. New script
804 util/mkfiles.pl to create the MINFO file on environments that can't do a
805 'make files': perl util/mkfiles.pl >MINFO should work.
808 *) Major rework of DES function declarations, in the pursuit of correctness
809 and purity. As a result, many evil casts evaporated, and some weirdness,
810 too. You may find this causes warnings in your code. Zapping your evil
811 casts will probably fix them. Mostly.
814 *) Fix for a typo in asn1.h. Bug fix to object creation script
815 obj_dat.pl. It considered a zero in an object definition to mean
816 "end of object": none of the objects in objects.h have any zeros
817 so it wasn't spotted.
818 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
820 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
821 Masking (CBCM). In the absence of test vectors, the best I have been able
822 to do is check that the decrypt undoes the encrypt, so far. Send me test
823 vectors if you have them.
826 *) Correct calculation of key length for export ciphers (too much space was
827 allocated for null ciphers). This has not been tested!
830 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
831 message is now correct (it understands "crypto" and "ssl" on its
832 command line). There is also now an "update" option. This will update
833 the util/ssleay.num and util/libeay.num files with any new functions.
835 perl util/mkdef.pl crypto ssl update
839 *) Overhauled the Perl interface (perl/*):
840 - ported BN stuff to OpenSSL's different BN library
841 - made the perl/ source tree CVS-aware
842 - renamed the package from SSLeay to OpenSSL (the files still contain
843 their history because I've copied them in the repository)
844 - removed obsolete files (the test scripts will be replaced
845 by better Test::Harness variants in the future)
846 [Ralf S. Engelschall]
848 *) First cut for a very conservative source tree cleanup:
849 1. merge various obsolete readme texts into doc/ssleay.txt
850 where we collect the old documents and readme texts.
851 2. remove the first part of files where I'm already sure that we no
852 longer need them because of three reasons: either they are just temporary
853 files which were left by Eric or they are preserved original files where
854 I've verified that the diff is also available in the CVS via "cvs diff
855 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
856 the crypto/md/ stuff).
857 [Ralf S. Engelschall]
859 *) More extension code. Incomplete support for subject and issuer alt
860 name, issuer and authority key id. Change the i2v function parameters
861 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
862 what that's for :-) Fix to ASN1 macro which messed up
863 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
866 *) Preliminary support for ENUMERATED type. This is largely copied from the
870 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
871 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
873 *) Make sure `make rehash' target really finds the `openssl' program.
874 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
876 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
877 like to hear about it if this slows down other processors.
880 *) Add CygWin32 platform information to Configure script.
881 [Alan Batie <batie@aahz.jf.intel.com>]
883 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
884 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
886 *) New program nseq to manipulate netscape certificate sequences
889 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
893 *) Fixes to BN code. Previously the default was to define BN_RECURSION
894 but the BN code had some problems that would cause failures when
895 doing certificate verification and some other functions.
896 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
898 *) Add ASN1 and PEM code to support netscape certificate sequences.
901 *) Add ASN1 and PEM code to support netscape certificate sequences.
904 *) Add several PKIX and private extended key usage OIDs.
907 *) Modify the 'ca' program to handle the new extension code. Modify
908 openssl.cnf for new extension format, add comments.
911 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
912 and add a sample to openssl.cnf so req -x509 now adds appropriate
916 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
917 error code, add initial support to X509_print() and x509 application.
920 *) Takes a deep breath and start addding X509 V3 extension support code. Add
921 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
922 stuff is currently isolated and isn't even compiled yet.
925 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
926 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
927 Removed the versions check from X509 routines when loading extensions:
928 this allows certain broken certificates that don't set the version
929 properly to be processed.
932 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
933 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
934 can still be regenerated with "make depend".
937 *) Spelling mistake in C version of CAST-128.
938 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
940 *) Changes to the error generation code. The perl script err-code.pl
941 now reads in the old error codes and retains the old numbers, only
942 adding new ones if necessary. It also only changes the .err files if new
943 codes are added. The makefiles have been modified to only insert errors
944 when needed (to avoid needlessly modifying header files). This is done
945 by only inserting errors if the .err file is newer than the auto generated
946 C file. To rebuild all the error codes from scratch (the old behaviour)
947 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
948 or delete all the .err files.
951 *) CAST-128 was incorrectly implemented for short keys. The C version has
952 been fixed, but is untested. The assembler versions are also fixed, but
953 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
954 to regenerate it if needed.
955 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
956 Hagino <itojun@kame.net>]
958 *) File was opened incorrectly in randfile.c.
959 [Ulf Möller <ulf@fitug.de>]
961 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
962 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
963 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
964 al: it's just almost always a UTCTime. Note this patch adds new error
965 codes so do a "make errors" if there are problems.
968 *) Correct Linux 1 recognition in config.
969 [Ulf Möller <ulf@fitug.de>]
971 *) Remove pointless MD5 hash when using DSA keys in ca.
972 [Anonymous <nobody@replay.com>]
974 *) Generate an error if given an empty string as a cert directory. Also
975 generate an error if handed NULL (previously returned 0 to indicate an
976 error, but didn't set one).
977 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
979 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
982 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
983 parameters. This was causing a warning which killed off the Win32 compile.
986 *) Remove C++ style comments from crypto/bn/bn_local.h.
987 [Neil Costigan <neil.costigan@celocom.com>]
989 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
990 based on a text string, looking up short and long names and finally
991 "dot" format. The "dot" format stuff didn't work. Added new function
992 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
993 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
994 OID is not part of the table.
997 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
998 X509_LOOKUP_by_alias().
1001 *) Sort openssl functions by name.
1004 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1005 encryption from sample DSA keys (in case anyone is interested the password
1009 *) Make _all_ *_free functions accept a NULL pointer.
1010 [Frans Heymans <fheymans@isaserver.be>]
1012 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1014 [Anonymous <nobody@replay.com>]
1016 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1017 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1019 *) Don't blow it for numeric -newkey arguments to apps/req.
1020 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1022 *) Temp key "for export" tests were wrong in s3_srvr.c.
1023 [Anonymous <nobody@replay.com>]
1025 *) Add prototype for temp key callback functions
1026 SSL_CTX_set_tmp_{rsa,dh}_callback().
1029 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1030 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1033 *) X509_name_add_entry() freed the wrong thing after an error.
1034 [Arne Ansper <arne@ats.cyber.ee>]
1036 *) rsa_eay.c would attempt to free a NULL context.
1037 [Arne Ansper <arne@ats.cyber.ee>]
1039 *) BIO_s_socket() had a broken should_retry() on Windoze.
1040 [Arne Ansper <arne@ats.cyber.ee>]
1042 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1043 [Arne Ansper <arne@ats.cyber.ee>]
1045 *) Make sure the already existing X509_STORE->depth variable is initialized
1046 in X509_STORE_new(), but document the fact that this variable is still
1047 unused in the certificate verification process.
1048 [Ralf S. Engelschall]
1050 *) Fix the various library and apps files to free up pkeys obtained from
1051 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1054 *) Fix reference counting in X509_PUBKEY_get(). This makes
1055 demos/maurice/example2.c work, amongst others, probably.
1056 [Steve Henson and Ben Laurie]
1058 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1059 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1060 are no longer created. This way we have a single and consistent command
1061 line interface `openssl <command>', similar to `cvs <command>'.
1062 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1064 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1065 BIT STRING wrapper always have zero unused bits.
1068 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1071 *) Make the top-level INSTALL documentation easier to understand.
1074 *) Makefiles updated to exit if an error occurs in a sub-directory
1075 make (including if user presses ^C) [Paul Sutton]
1077 *) Make Montgomery context stuff explicit in RSA data structure.
1080 *) Fix build order of pem and err to allow for generated pem.h.
1083 *) Fix renumbering bug in X509_NAME_delete_entry().
1086 *) Enhanced the err-ins.pl script so it makes the error library number
1087 global and can add a library name. This is needed for external ASN1 and
1088 other error libraries.
1091 *) Fixed sk_insert which never worked properly.
1094 *) Fix ASN1 macros so they can handle indefinite length construted
1095 EXPLICIT tags. Some non standard certificates use these: they can now
1099 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1100 into a single doc/ssleay.txt bundle. This way the information is still
1101 preserved but no longer messes up this directory. Now it's new room for
1102 the new set of documenation files.
1103 [Ralf S. Engelschall]
1105 *) SETs were incorrectly DER encoded. This was a major pain, because they
1106 shared code with SEQUENCEs, which aren't coded the same. This means that
1107 almost everything to do with SETs or SEQUENCEs has either changed name or
1108 number of arguments.
1109 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1111 *) Fix test data to work with the above.
1114 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1115 was already fixed by Eric for 0.9.1 it seems.
1116 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1118 *) Autodetect FreeBSD3.
1121 *) Fix various bugs in Configure. This affects the following platforms:
1125 unixware-2.0-pentium
1129 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1130 before they are needed.
1133 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1137 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1139 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1140 changed SSLeay to OpenSSL in version strings.
1141 [Ralf S. Engelschall]
1143 *) Some fixups to the top-level documents.
1146 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1147 because the symlink to include/ was missing.
1148 [Ralf S. Engelschall]
1150 *) Incorporated the popular no-RSA/DSA-only patches
1151 which allow to compile a RSA-free SSLeay.
1152 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1154 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1155 when "ssleay" is still not found.
1156 [Ralf S. Engelschall]
1158 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1159 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1161 *) Updated the README file.
1162 [Ralf S. Engelschall]
1164 *) Added various .cvsignore files in the CVS repository subdirs
1165 to make a "cvs update" really silent.
1166 [Ralf S. Engelschall]
1168 *) Recompiled the error-definition header files and added
1169 missing symbols to the Win32 linker tables.
1170 [Ralf S. Engelschall]
1172 *) Cleaned up the top-level documents;
1173 o new files: CHANGES and LICENSE
1174 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1175 o merged COPYRIGHT into LICENSE
1176 o removed obsolete TODO file
1177 o renamed MICROSOFT to INSTALL.W32
1178 [Ralf S. Engelschall]
1180 *) Removed dummy files from the 0.9.1b source tree:
1181 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1182 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1185 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1186 [Ralf S. Engelschall]
1188 *) Added various platform portability fixes.
1191 *) The Genesis of the OpenSSL rpject:
1192 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1193 Young and Tim J. Hudson created while they were working for C2Net until
1195 [The OpenSSL Project]
1198 Changes between 0.9.0b and 0.9.1b [not released]
1200 *) Updated a few CA certificates under certs/
1203 *) Changed some BIGNUM api stuff.
1206 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1207 DGUX x86, Linux Alpha, etc.
1210 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1211 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1215 *) Add -strparse option to asn1pars program which parses nested
1217 [Dr Stephen Henson <shenson@bigfoot.com>]
1219 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1222 *) DSA fix for "ca" program.
1225 *) Added "-genkey" option to "dsaparam" program.
1228 *) Added RIPE MD160 (rmd160) message digest.
1231 *) Added -a (all) option to "ssleay version" command.
1234 *) Added PLATFORM define which is the id given to Configure.
1237 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1240 *) Extended the ASN.1 parser routines.
1243 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1246 *) Added a BN_CTX to the BN library.
1249 *) Fixed the weak key values in DES library
1252 *) Changed API in EVP library for cipher aliases.
1255 *) Added support for RC2/64bit cipher.
1258 *) Converted the lhash library to the crypto/mem.c functions.
1261 *) Added more recognized ASN.1 object ids.
1264 *) Added more RSA padding checks for SSL/TLS.
1267 *) Added BIO proxy/filter functionality.
1270 *) Added extra_certs to SSL_CTX which can be used
1271 send extra CA certificates to the client in the CA cert chain sending
1272 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1275 *) Now Fortezza is denied in the authentication phase because
1276 this is key exchange mechanism is not supported by SSLeay at all.
1279 *) Additional PKCS1 checks.
1282 *) Support the string "TLSv1" for all TLS v1 ciphers.
1285 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1286 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1289 *) Fixed a few memory leaks.
1292 *) Fixed various code and comment typos.
1295 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1296 bytes sent in the client random.
