Crypto++ 2.1 has just been released. You can find download instructions on the Crypto++ home page at http://www.eskimo.com/~weidai/cryptlib.html. Crypto++ is a free C++ class library of cryptographic primitives. Changes made in version 2.1 include: - added Tiger, HMAC, GOST, RIPE-MD160, LUCELG, LUCDIF, XOR-MAC, OAEP, PSSR, SHARK - added precomputation to DH, ElGamal, DSA, and elliptic curve algorithms - optimizations in elliptic curves over GF(p) - changed Rabin to use OAEP and PSSR - changed many classes to allow copy constructors to work correctly - improved exception generation and handling This is likely to be the last major revision of Crypto++. Future versions will probably only be released for bug fixes and compliance to new standards. Wei Dai P.S. A new set of benchmarks done using Crypto++ 2.1 is available at http://www.eskimo.com/~weidai/benchmarks.txt.
