Bitsliced AES

[DavidBuchanan314]

I see that a bitsliced AES implementation is in the "Future Plans" list.

This is something I've toyed with in the past, and would be interested in contributing.

Just to check that we're talking about the same concept, the idea is to pack n 128-bit message blocks into 128 n-bit python bigints, and then perform a bitsliced AES algorithm in pure-python, before unpacking the message back into bytes.

If I implemented this, would it be a useful contribution?

P.S. How fast should it be, ideally, to be considered practical?
