NAME: Rijndael
CREATOR: Joan Daemen and Vincent Rijmen
PB AUTHOR: Greg Turgeon
DESCRIPTION: PBCC3/PBWIN7 implementation of Rijndael - the AES (Advanced Encryption Standard) cipher. Rijndael is relatively fast, has a design heavily influenced by the block cipher Square, and features variable block and key lengths (128, 192, or 256 bits).
NOTES: See also Steven Pringels' PBCC2/PBDLL6 implementation (suitable for all versions of PowerBASIC).
Note that Steven Pringel's port uses a fixed block length of 256 bits, likewise the key is expanded to 256 bits. Greg Turgeon's sample is the implementation of Rijndael which specifies a block length of only 128 bits.
