Open source cryptographic library

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
