I’ve been always fan of (much more secure) Serpent cipher instead of AES/Rijandel and today I can feel like a messiah. Enjoy this article http://www.theregister.co.uk/2011/08/19/aes_crypto_attack/
BTW: from WIKI:
Serpent was widely viewed as taking a more conservative approach to security than the other AES finalists, opting for a larger security margin: the designers deemed 16 rounds to be sufficient against known types of attack, but specified 32 rounds as insurance against future discoveries in cryptanalysis.
Of course it doesn’t make AES completely useless, but it raises some concerns
