description     Crypto library
long_description \
    Libgcrypt is a general purpose cryptographic library originally \
    based on code from GnuPG. It provides functions for all \
    cryptographic building blocks: symmetric cipher algorithms and \
    modes, hash algorithms, MACs, public key algorithms, large integer \
    functions, random numbers and a lot of supporting functions.
