"Change Set: AES
Date: 24 November 2006
Author: Timothy J. Miller
Refactored as a single class with a stab at a factory method. Someone
should probably check to make sure I'm doing the generation in a sane
fashion. If an invalid key length is used, 256 is used as a default.
And I should get to bed, I know. Tested with the FIPS 197 test vectors.
I promise I'll work on a test class next."!
