DESCRIPTION: Libgcrypt is a general purpose cryptographic library based on the code from GnuPG. 

Overview

Libgcrypt is a general purpose cryptographic library based on the code from
GnuPG.  It provides functions for all cryptograhic building blocks:
symmetric ciphers (AES, DES, Blowfish, CAST5, Twofish, SEED, Camellia,
Arcfour), hash algorithms (MD4, MD5, RIPE-MD160, SHA-1, SHA-224, SHA-256,
SHA-384, SHA-512, TIGER-192, Whirlpool), MACs (HMAC for all hash
algorithms), public key algorithms (RSA, Elgamal, DSA, ECDSA), large integer
functions, random numbers and a lot of supporting functions.

Libgcrypt works on most POSIX systems and many pre-POSIX systems.
