If you're not desperate to pull apart the algorithm, then leveraging the Java implementation might be the way to go, considering Mathematica seems to get along with Java reasonably well. Rijndael is supposed to be integrated into Java 1.4.1, though I found it to be missing from 1.4.0. Check out the javax.crypto package. If you look at the algorithm spec, it's all fast operations on bytes. It's tricky to make some of the operations (like the key-schedule) work in a functional manner, and the result is pretty unreadable compared to the original spec IMHO. Some of the algebraic operations can be made to look more elegent in Mathematica though.
