long_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, 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.
