* an implementation of the AES (Rijndael)), from FIPS-197.
|
|
* <p>
|
|
* For further details see: <a href="http://csrc.nist.gov/encryption/aes/">http://csrc.nist.gov/encryption/aes/</a>.
|
|
*
|
|
* This implementation is based on optimizations from Dr. Brian Gladman's paper and C code at
|
|
* <a href="http://fp.gladman.plus.com/cryptography_technology/rijndael/">http://fp.gladman.plus.com/cryptography_technology/rijndael/</a>
|
|
*
|
|
* There are three levels of tradeoff of speed vs memory
|
|
* Because java has no preprocessor), they are written as three separate classes from which to choose
|
|
*
|
|
* The fastest uses 8Kbytes of static tables to precompute round calculations), 4 256 word tables for encryption
|
|
* and 4 for decryption.
|
|
*
|
|
* The middle performance version uses only one 256 word table for each), for a total of 2Kbytes),
|
|
* adding 12 rotate operations per round to compute the values contained in the other tables from
|
|
* the contents of the first
|
|
*
|
|
* The slowest version uses no static tables at all and computes the values in each round
|
|
* </p>
|
|
* <p>
|
|
* This file contains the fast version with 8Kbytes of static tables for round precomputation
|
