2 * Cryptographic API.
3 *
4 * Anubis Algorithm
5 *
6 * The Anubis algorithm was developed by Paulo S. L. M. Barreto and
7 * Vincent Rijmen.
8 *
9 * See
10 *
11 * P.S.L.M. Barreto, V. Rijmen,
12 * ``The Anubis block cipher,''
13 * NESSIE submission, 2000.
14 *
15 * This software implements the "tweaked" version of Anubis.
16 * Only the S-box and (consequently) the rounds constants have been
17 * changed.
18 *
19 * The original authors have disclaimed all copyright interest in this
20 * code and thus put it in the public domain. The subsequent authors
21 * have put this under the GNU General Public License.
