define Package/libgcrypt/description
 This is a general purpose cryptographic library based on the code from 
 GnuPG. It provides functions for all cryptograhic building blocks: 
 symmetric ciphers (AES, DES, Arcfour), hash algorithms (MD5, SHA-1,
 RIPE-MD160, SHA-224/256, SHA-384/512), MACs (HMAC for all hash
 algorithms), public key algorithms (RSA, DSA), large integer functions,
 random numbers and a lot of supporting functions. Some algorithms have
 been disabled to reduce size (Blowfish, CAST5, Twofish, Serpent,
 RC2, SEED, Camellia, CRC, MD4, TIGER-192, Whirlpool, ElGamal, ECC).
