Uhh, that wasn't really what I was after, that's pretty much textbook stuff,
what I wanted was specifically advice on how to use block ciphers in a way
that avoids possibilities for side-channel (and similar) attacks. I have some
initial notes that can be summarised as "Don't let yourself be used as an
oracle" that I was planning to add after I've fleshed them out a bit.
