+--gnu.crypto.hash.Tiger
The Tiger message digest. Tiger was designed by Ross Anderson and Eli Biham, with the goal of producing a secure, fast hash function that performs especially well on next-generation 64-bit architectures, but is still efficient on 32- and 16-bit architectures.
Tiger processes data in 512-bit blocks and produces a 192-bit digest.
