/* rijndael-api.h - Rijndael encryption programming interface.

* Author: Kees J. Bot
|
|
* 3 Nov 2000
|
|
* Heavily based on the original API code by Antoon Bosselaers,
|
|
* Vincent Rijmen, and Paulo Barreto, but with a different interface.
|
|
*
|
|
* This code (.h and .c) is in the public domain.
