Discussing the interface issues would be one of the interesting parts of
this issue!

This also was my general direction of thought when I made the proposal.
Different block ciphers could be added, then classes to wrap block
ciphers into stream ciphers, and so on.

For a block cipher? Hmmm... Well, probably you're right, but I'd argue
to restrict ourselves to random access iterators in that case (to be
able to check the block size).

PS: what about export regulations in certain countries? Would adding
cryptography create problems?
