This module implements Rijndael(AES) crypto algorithm by Vincent Rijmen, Antoon Bosselaers and Paulo Barreto.

Code based on version 3.0 (December 2000) of Optimised ANSI C code for the Rijndael cipher [http://www.fastcrypto.org/front/misc/rijndael-alg-fst.c].

Tests made according to official test vectors (Appendix B and Appendix C) [http://csrc.nist.gov/groups/STM/cavp/documents/aes/AESAVS.pdf].
