30 * An implementation of the AES (Rijndael), from FIPS-197.
31 * <p>
32 * For further details see: <a
33 * href="http://csrc.nist.gov/encryption/aes/">http://csrc.nist.gov/encryption/aes/
34 * </a>.
35 *
36 * This implementation is based on optimizations from Dr. Brian Gladman's paper
37 * and C code at <a
38 * href="http://fp.gladman.plus.com/cryptography_technology/rijndael/">http://fp.gladman.plus.com/cryptography_technology/rijndael/
39 * </a>
40 *
41 * There are three levels of tradeoff of speed vs memory Because java has no
42 * preprocessor, they are written as three separate classes from which to choose
43 *
44 * The fastest uses 8Kbytes of static tables to precompute round calculations, 4
45 * 256 word tables for encryption and 4 for decryption.
46 *
47 * The middle performance version uses only one 256 word table for each, for a
48 * total of 2Kbytes, adding 12 rotate operations per round to compute the values
49 * contained in the other tables from the contents of the first
50 *
51 * The slowest version uses no static tables at all and computes the values in
52 * each round
53 * <p>
54 * This file contains the fast version with 8Kbytes of static tables for round
55 * precomputation
56 *
57 * @author See comments in the source file
