- * Glue Code for optimized x86_64 assembler version of TWOFISH

- * Originally Twofish for GPG
- * By Matthew Skala <mskala@ansuz.sooke.bc.ca>, July 26, 1998
- * 256-bit key length added March 20, 1999
- * Some modifications to reduce the text size by Werner Koch, April, 1998
- * Ported to the kerneli patch by Marc Mutz <Marc@Mutz.com>
