 * Cryptographic API.

 * Anubis Algorithm
 *
 * The Anubis algorithm was developed by Paulo S. L. M. Barreto and
 * Vincent Rijmen.
 *
 * See

 *	P.S.L.M. Barreto, V. Rijmen,
 *	``The Anubis block cipher,''
 *	NESSIE submission, 2000.
 *
 * This software implements the "tweaked" version of Anubis.
 * Only the S-box and (consequently) the rounds constants have been
 * changed.
