Re: DES

My take on breaking DES would be to just try all 2**56th keys on a 
massively parallel machine, though there may be better approaches.

This isn't breaking DES. The best any encryption scheme can hope
for is to only be broken by exhaustive search.

A massively parallel colection of dedicated DES encryption hardware
might be more cost effective if had alot of these things to crack.

Speaking of which, does anyone know who makes "the DES chip" (is
there more than one?)? I'd like to find a data sheet for it.

Many manufacturers make DES chips.  One that comes to mind is American Micro
Devices, though I don't remember a part number off hand.  I can find out and
post it to the list.  I do remember reading the data sheet, and it looked
like a nice implementation.  If I'm not mistaken, Motorola makes one as well,
though it may have been obsoleted by improvements in speed.
