   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.

  12 * This version is derived from the GnuPG implementation and the
  13 * Tiger-Perl interface written by Rafael Sevilla
