 OpenSSL CHANGES
 Changes between 0.9.8a and 0.9.9  [xx XXX xxxx]
  *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
     in addition to the text details.
     [Bodo Moeller]

  *) Very, very preliminary EXPERIMENTAL support for printing of general
     ASN1 structures. This currently produces rather ugly output and doesn't
     handle several customised structures at all.
     [Steve Henson]

  *) Integrated support for PVK file format and some related formats such
     as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
     these in the 'rsa' and 'dsa' utilities.
     [Steve Henson]

  *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
     [Steve Henson]

  *) Remove the ancient ASN1_METHOD code. This was only ever used in one
     place for the (very old) "NETSCAPE" format certificates which are now
     handled using new ASN1 code equivalents.
  *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
     pointer and make the SSL_METHOD parameter in SSL_CTX_new,
     SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
     [Nils Larsch]

  *) Modify CRL distribution points extension code to print out previously
     unsupported fields. Enhance extension setting code to allow setting of
     all fields.
  *) Add print and set support for Issuing Distribution Point CRL extension.
 Changes between 0.9.8 and 0.9.8a  [XX xxx XXXX]

  *) Add two function to clear and return the verify parameter flags.
     [Steve Henson]

  *) Keep cipherlists sorted in the source instead of sorting them at
     runtime, thus removing the need for a lock.
     [Nils Larsch]

  *) Avoid some small subgroup attacks in Diffie-Hellman.
     [Nick Mathewson and Ben Laurie]

  *) Add functions for well-known primes.
     [Nick Mathewson]

  *) Extended Windows CE support.
     [Satoshi Nakamura and Andy Polyakov]
 
  *) Initialize SSL_METHOD structures at compile time instead of during
     runtime, thus removing the need for a lock.
     [Steve Henson]

  *) Make PKCS7_decrypt() work even if no certificate is supplied by
     attempting to decrypt each encrypted key in turn. Add support to
     smime utility.
     [Steve Henson]

 Changes between 0.9.7h and 0.9.8  [05 Jul 2005]
  *) Add libcrypto.pc and libssl.pc for those who feel they need them.
     [Richard Levitte]

  *) Change CA.sh and CA.pl so they don't bundle the CSR and the private
     key into the same file any more.
     [Richard Levitte]

  *) Add initial support for Win64, both IA64 and AMD64/x64 flavors.
     [Andy Polyakov]

  *) Add -utf8 command line and config file option to 'ca'.
     [Stefan <stf@udoma.org]

  *) Removed the macro des_crypt(), as it seems to conflict with some
     libraries.  Use DES_crypt().
     [Richard Levitte]

  *) Correct naming of the 'chil' and '4758cca' ENGINEs. This
     involves renaming the source and generated shared-libs for
     both. The engines will accept the corrected or legacy ids
     ('ncipher' and '4758_cca' respectively) when binding. NB,
     this only applies when building 'shared'.
     [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]

  *) Add attribute functions to EVP_PKEY structure. Modify
     PKCS12_create() to recognize a CSP name attribute and
     use it. Make -CSP option work again in pkcs12 utility.
     [Steve Henson]

  *) Add new functionality to the bn blinding code:
     - automatic re-creation of the BN_BLINDING parameters after
       a fixed number of uses (currently 32)
     - add new function for parameter creation
     - introduce flags to control the update behaviour of the
       BN_BLINDING parameters
     - hide BN_BLINDING structure
     Add a second BN_BLINDING slot to the RSA structure to improve
     performance when a single RSA object is shared among several
     threads.
     [Nils Larsch]

  *) Add support for DTLS.
     [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]

  *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
     to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
     [Walter Goulet]

  *) Remove buggy and incompletet DH cert support from
     ssl/ssl_rsa.c and ssl/s3_both.c
     [Nils Larsch]

  *) Use SHA-1 instead of MD5 as the default digest algorithm for
     the apps/openssl applications.

  *) Compile clean with "-Wall -Wmissing-prototypes
     -Wstrict-prototypes -Wmissing-declarations -Werror". Currently
     DEBUG_SAFESTACK must also be set.
     [Ben Laurie]

  *) Change ./Configure so that certain algorithms can be disabled by default.
     The new counterpiece to "no-xxx" is "enable-xxx".

     The patented RC5 and MDC2 algorithms will now be disabled unless
     "enable-rc5" and "enable-mdc2", respectively, are specified.

     (IDEA remains enabled despite being patented.  This is because IDEA
     is frequently required for interoperability, and there is no license
     fee for non-commercial use.  As before, "no-idea" can be used to
     avoid this algorithm.)

  *) Add processing of proxy certificates (see RFC 3820).  This work was
     sponsored by KTH (The Royal Institute of Technology in Stockholm) and
     EGEE (Enabling Grids for E-science in Europe).
     [Richard Levitte]

  *) RC4 performance overhaul on modern architectures/implementations, such
     as Intel P4, IA-64 and AMD64.
     [Andy Polyakov]

  *) New utility extract-section.pl. This can be used specify an alternative
     section number in a pod file instead of having to treat each file as
     a separate case in Makefile. This can be done by adding two lines to the
     pod file:

     =for comment openssl_section:XXX

     The blank line is mandatory.

  *) New arguments -certform, -keyform and -pass for s_client and s_server
     to allow alternative format key and certificate files and passphrase
     sources.
     [Steve Henson]

  *) New structure X509_VERIFY_PARAM which combines current verify parameters,
     update associated structures and add various utility functions.

     Add new policy related verify parameters, include policy checking in 
     standard verify code. Enhance 'smime' application with extra parameters
     to support policy checking and print out.
     [Steve Henson]

  *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
     Nehemiah processors. These extensions support AES encryption in hardware
     as well as RNG (though RNG support is currently disabled).
     [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]

  *) Deprecate BN_[get|set]_params() functions (they were ignored internally).
     [Geoff Thorpe]

  *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
     [Andy Polyakov and a number of other people]

  *) Improved PowerPC platform support. Most notably BIGNUM assembler
     implementation contributed by IBM.
     [Suresh Chari, Peter Waltenberg, Andy Polyakov]

  *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
     exponent rather than 'unsigned long'. There is a corresponding change to
     the new 'rsa_keygen' element of the RSA_METHOD structure.
     [Jelte Jansen, Geoff Thorpe]

  *) Functionality for creating the initial serial number file is now
     moved from CA.pl to the 'ca' utility with a new option -create_serial.
