4 * Tiger hashing Algorithm
5 *
6 * Copyright (C) 1998 Free Software Foundation, Inc.
7 *
8 * The Tiger algorithm was developed by Ross Anderson and Eli Biham.
9 * It was optimized for 64-bit processors while still delievering
10 * decent performance on 32 and 16-bit processors.
11 *
12 * This version is derived from the GnuPG implementation and the
13 * Tiger-Perl interface written by Rafael Sevilla
