I've read it Perry. Hilary said this years' Crypto had a session showing
that 2 key 3DES was no better than DES. I'm asking for the details, or
some refutation.
And I have asked twice: what folks have implemented 3DES in hardware, so
we can make a sensible decision on how to generate the keys?
I consider software more maleable than hardware. If no one speaks up,
it will be clear that nobody important has done anything in hardware,
and what I write on the topic will be acceptable and final.
