I liked this part.  They estimate the "security" of AES at:

2^127.88476373519208801711541761570483401788
with 2^127 precomputation.

Is there any reason for stating a shot-in-the-dark security guess to 42
significant digits?

Anyway, the method used in AES to generate the S-boxes are a bit scary in
the first place.
