security/beecrypt 4.2.1_3 DragonFly

BeeCrypt is an open source cryptography library that contains highly optimized C and assembler implementations of many well-known algorithms including Blowfish, MD5, SHA-1, Diffie-Hellman, and ElGamal. Unlike some other crypto libraries, BeeCrypt is not designed to solve one specific problem, like file encryption, but to be a general purpose toolkit which can be used in a variety of applications.

The BeeCrypt library currently includes:

• Entropy sources for initializing pseudo-random generators
• Pseudo-random generators: FIPS-186, Mersenne Twister
• Block ciphers: Blowfish
• Hash functions: MD5, SHA-1, SHA-256
• Keyed hash functions: MD5/HMAC, SHA-1/HMAC, SHA-256/HMAC
• Multi-precision integer library, with assembler-optimized routines
• Probabilistic primality testing, with optimized small prime trial division
• Discrete logarithm parameter generation over a prime field
• Diffie-Hellman key agreement
• DHAES encryption scheme
• ElGamal signature scheme (two variants)
• Basic RSA primitives and key pair generation
