 Changes between 0.9.2b and 0.9.3

  *) Complete rewrite of the error code script(s). It is all now handled
     by one script at the top level which handles error code gathering,
     header rewriting and C source file generation. It should be much better
     than the old method: it now uses a modified version of Ulf's parser to
     read the ANSI prototypes in all header files (thus the old K&R definitions
     aren't needed for error creation any more) and do a better job of
     translating function codes into names. The old 'ASN1 error code imbedded
     in a comment' is no longer necessary and it doesn't use .err files which
     have now been deleted.
     [Steve Henson]

  *) Change #include filenames from <foo.h> to <openssl/foo.h>.
     [Bodo Moeller]

  *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
     0 (which usually indicates a closed connection), but continue reading.
     [Bodo Moeller]

  *) Fix some race conditions.
     [Bodo Moeller]

  *) Add support for CRL distribution points extension. Add Certificate
     Policies and CRL distribution points documentation.
     [Steve Henson]

  *) Move the autogenerated header file parts to crypto/opensslconf.h.
     [Ulf Möller]

  *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
     8 of keying material. Merlin has also confirmed interop with this fix
     between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
     [Merlin Hughes <merlin@baltimore.ie>]

  *) Fix lots of warnings.
     [Richard Levitte <levitte@stacken.kth.se>]
 
  *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
     the directory spec didn't end with a LIST_SEPARATOR_CHAR.
     [Richard Levitte <levitte@stacken.kth.se>]
 
  *) Fix problems with sizeof(long) == 8.
     [Andy Polyakov <appro@fy.chalmers.se>]

  *) Change functions to ANSI C.
     [Ulf Möller]

  *) Fix typos in error codes.
     [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]

  *) Remove defunct assembler files from Configure.
     [Ulf Möller]

  *) SPARC v8 assembler BIGNUM implementation.
     [Andy Polyakov <appro@fy.chalmers.se>]

  *) Support for Certificate Policies extension: both print and set.
     Various additions to support the r2i method this uses.
     [Steve Henson]

  *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
     return a const string when you are expecting an allocated buffer.
     [Ben Laurie]

  *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
     types DirectoryString and DisplayText.
     [Steve Henson]

  *) Add code to allow r2i extensions to access the configuration database,
     add an LHASH database driver and add several ctx helper functions.
     [Steve Henson]

  *) Fix an evil bug in bn_expand2() which caused various BN functions to
     fail when they extended the size of a BIGNUM.
     [Steve Henson]

  *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
     support typesafe stack.
     [Steve Henson]

  *) Fix typo in SSL_[gs]et_options().
     [Nils Frostberg <nils@medcom.se>]

  *) Delete various functions and files that belonged to the (now obsolete)
     old X509V3 handling code.
     [Steve Henson]

  *) New Configure option "rsaref".
     [Ulf Möller]

  *) Don't auto-generate pem.h.
     [Bodo Moeller]

  *) Introduce type-safe ASN.1 SETs.
     [Ben Laurie]

  *) Introduce type-safe STACKs. This will almost certainly break lots of code
     that links with OpenSSL (well at least cause lots of warnings), but fear
     not: the conversion is trivial, and it eliminates loads of evil casts. A
     few STACKed things have been converted already. Feel free to convert more.
     In the fullness of time, I'll do away with the STACK type altogether.
     [Ben Laurie]

  *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
     specified in <certfile> by updating the entry in the index.txt file.
     This way one no longer has to edit the index.txt file manually for
     revoking a certificate. The -revoke option does the gory details now.
     [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]

  *) Fix `openssl crl -noout -text' combination where `-noout' killed the
     `-text' option at all and this way the `-noout -text' combination was
     inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
     [Ralf S. Engelschall]

  *) Make sure a corresponding plain text error message exists for the
     X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
     verify callback function determined that a certificate was revoked.
     [Ralf S. Engelschall]

  *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
     ciphers that were excluded, e.g. by -DNO_IDEA.  Also, test
     all available cipers including rc5, which was forgotten until now.
     In order to let the testing shell script know which algorithms
     are available, a new (up to now undocumented) command
     "openssl list-cipher-commands" is used.
     [Bodo Moeller]

  *) Bugfix: s_client occasionally would sleep in select() when
     it should have checked SSL_pending() first.
     [Bodo Moeller]

  *) New functions DSA_do_sign and DSA_do_verify to provide access to
     the raw DSA values prior to ASN.1 encoding.
     [Ulf Möller]

  *) Tweaks to Configure
     Niels Poppe <niels@netbox.org>

  *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
     yet...
     [Steve Henson]

  *) New variables $(RANLIB) and $(PERL) in the Makefiles.
     [Ulf Möller]

  *) New config option to avoid instructions that are illegal on the 80386.
     The default code is faster, but requires at least a 486.
     [Ulf Möller]
  
  *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
     SSL2_SERVER_VERSION (not used at all) macros, which are now the
     same as SSL2_VERSION anyway.
     [Bodo Moeller]

  *) New "-showcerts" option for s_client.
     [Bodo Moeller]

  *) Still more PKCS#12 integration. Add pkcs12 application to openssl
     application. Various cleanups and fixes.
     [Steve Henson]

  *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
     modify error routines to work internally. Add error codes and PBE init
     to library startup routines.
     [Steve Henson]

  *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
     packing functions to asn1 and evp. Changed function names and error
     codes along the way.
     [Steve Henson]

  *) PKCS12 integration: and so it begins... First of several patches to
     slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
     objects to objects.h
     [Steve Henson]

  *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
     and display support for Thawte strong extranet extension.
     [Steve Henson]

  *) Add LinuxPPC support.
     [Jeff Dubrule <igor@pobox.org>]

  *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
     bn_div_words in alpha.s.
     [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]

  *) Make sure the RSA OAEP test is skipped under -DRSAref because
     OAEP isn't supported when OpenSSL is built with RSAref.
     [Ulf Moeller <ulf@fitug.de>]

  *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h 
     so they no longer are missing under -DNOPROTO. 
     [Soren S. Jorvang <soren@t.dk>]
