This file gives a brief overview of the major changes between each OpenSSL
release. For more details please read the CHANGES file.
+ Major changes between OpenSSL 0.9.7g and OpenSSL 0.9.8:
+
+ o Major work on the BIGNUM library for higher efficiency and to
+ make operations more streamlined and less contradictory. This
+ is the result of a major audit of the BIGNUM library.
+ o Addition of BIGNUM functions for fields GF(2^m) and NIST
+ curves, to support the Elliptic Crypto functions.
+ o Major work on Elliptic Crypto; ECDH and ECDSA added, including
+ the use through EVP, X509 and ENGINE.
+ o New ASN.1 mini-compiler that's usable through the OpenSSL
+ configuration file.
+ o Added support for ASN.1 indefinite length constructed encoding.
+ o New PKCS#12 'medium level' API to manipulate PKCS#12 files.
+ o Complete rework of shared library construction and linking
+ programs with shared or static libraries, through a separate
+ Makefile.shared.
+ o Changed ENGINE framework to load dynamic engine modules
+ automatically from specifically given directories.
+ o New structure and ASN.1 functions for CertificatePair.
+ o Changed the ZLIB compression method to be stateful.
+ o Changed the key-generation and primality testing "progress"
+ mechanism to take a structure that contains the ticker
+ function and an argument.
+ o New engine module: GMP (performs private key exponentiation).
+ o New engine module: VIA PadLOck ACE extension in VIA C3
+ Nehemiah processors.
+ o Added support for IPv6 addresses in certificate extensions.
+ See RFC 1884, section 2.2.
+ o Added support for certificate policy mappings, policy
+ constraints and name constraints.
+ o Added support for multi-valued AVAs in the OpenSSL
+ configuration file.
+ o Added support for multiple certificates with the same subject
+ in the 'openssl ca' index file.
+ o Make it possible to create self-signed certificates using
+ 'openssl ca -selfsign'.
+ o Make it possible to generate a serial number file with
+ 'openssl ca -create_serial'.
+ o New binary search functions with extended functionality.
+ o New BUF functions.
+ o New STORE structure and library to provide an interface to all
+ sorts of data repositories. Supports storage of public and
+ private keys, certificates, CRLs, numbers and arbitrary blobs.
+ This library is unfortunately unfinished and unused withing
+ OpenSSL.
+ o New control functions for the error stack.
+ o Changed the PKCS#7 library to support one-pass S/MIME
+ processing.
+ o Added the possibility to compile without old deprecated
+ functionality with the OPENSSL_NO_DEPRECATED macro or the
+ 'no-deprecated' argument to the config and Configure scripts.
+ o Constification of all ASN.1 conversion functions, and other
+ affected functions.
+ o Improved platform support for PowerPC.
+ o New FIPS 180-2 algorithms (SHA-224, -256, -384 and -512).
+ o New X509_VERIFY_PARAM structure to support parametrisation
+ of X.509 path validation.
+ o Major overhaul of RC4 performance on Intel P4, IA-64 and
+ AMD64.
+ o Changed the Configure script to have some algorithms disabled
+ by default. Those can be explicitely enabled with the new
+ argument form 'enable-xxx'.
+ o Change the default digest in 'openssl' commands from MD5 to
+ SHA-1.
+ o Added support for DTLS. THIS IS STILL BEING WORKED ON!
+ o New BIGNUM blinding.
+ o Added support for the RSA-PSS encryption scheme
+ o Added support for the RSA X.931 padding.
+
Major changes between OpenSSL 0.9.7f and OpenSSL 0.9.7g:
o More compilation issues fixed.
