Whirlpool hash algorithm.
Whirlpool is part of the NESSIE cryptographic primtives.
Whirlpool works on messages shorter than 2^256 bits and
produces a 512 bit hash.
Whirlpool hash algorithm 512, 384 and 256-bit hashes
Whirlpool-512 is part of the NESSIE cryptographic primtives.
Whirlpool will be part of the ISO/IEC 10118-3:2003(E) standard
