What is it all about?
Libgcrypt is a cryptographic library based on the GnuPG Implementations.
It supply variety of functions for all cryptograhic kinds such as symmetric ciphers (AES, DES, Blowfish, CAST5, Twofish, Arcfour), hash algorithms (MD4, MD5, RIPE-MD160, SHA-1, TIGER-192), MACs (HMAC for all hash algorithms), public key algorithms (RSA, ElGamal, DSA), large integer functions, random numbers and a lot of supporting functions. * Libgcrypt works on most POSIX systems and many pre-POSIX systems. * It can also be built using a cross-compiler system for Microsoft Windows.
