Speaking of changes to the 3-DES checksum formats --- I believe it's an
open question whether for the 3-DES suite whether we should use a
SHA_DES3 checksum, or do something like Hugo's HMAC-SHA, which doesn't
actually use an encryption algorithm to do the keyed hash.
Getting some imput from Real Cryptographers would probably be a good
idea before we formalize what's officially used in the 3-DES suite of
algorithms.
