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).

cryptography create problems?
