47 /*----- Notes on the Noekeon block cipher --------------------------------*
49 * A Nessie entry, by Joan Daemen, Michael Peeters, Gilles Van Assche and
50 * Vincent Rijmen, two of whom were the designers of the AES winner
51 * Rijndael. It's a simple cipher, based on Serpent-style bit-slicing.
52 * Speed is about middle-of-the-road -- about as fast as SAFER, faster than
