 Changes between 0.9.2b and 0.9.3

  *) New function SSL_CTX_use_certificate_chain_file that sets the
     "extra_cert"s in addition to the certificate.  (This makes sense
     only for "PEM" format files, as chains as a whole are not
     DER-encoded.)
     [Bodo Moeller]

  *) Support verify_depth from the SSL API.
     x509_vfy.c had what can be considered an off-by-one-error:
     Its depth (which was not part of the external interface)
     was actually counting the number of certificates in a chain;
     now it really counts the depth.
     [Bodo Moeller]

  *) New function SSL_CTX_set_session_id_context that allows to set a default
     value (so that you don't need SSL_set_session_id_context for each
     connection using the SSL_CTX).
     [Bodo Moeller]

  *) OAEP decoding bug fix.
     [Ulf Möller]

  *) Support INSTALL_PREFIX for package builders, as proposed by
     David Harris.
     [Bodo Moeller]

  *) New Configure options "threads" and "no-threads".  For systems
     where the proper compiler options are known (currently Solaris
     and Linux), "threads" is the default.
     [Bodo Moeller]

  *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
     [Bodo Moeller]

  *) Install various scripts to $(OPENSSLDIR)/misc, not to
     $(INSTALLTOP)/bin -- they shouldn't clutter directories
     such as /usr/local/bin.
     [Bodo Moeller]

  *) "make linux-shared" to build shared libraries.
     [Niels Poppe <niels@netbox.org>]

  *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
     [Ulf Möller]

  *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
     extension adding in x509 utility.
     [Steve Henson]

  *) Remove NOPROTO sections and error code comments.
     [Ulf Möller]

  *) Partial rewrite of the DEF file generator to now parse the ANSI
     prototypes.
     [Steve Henson]

  *) New Configure options --prefix=DIR and --openssldir=DIR.
     [Ulf Möller]

  *) 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. Also the error code call doesn't have to appear all
     on one line (which resulted in some large lines...).
     [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]
