Summary: DES breaking alg...


	I believe the reference to a DES breaking alg was about the hotrod
IBM PC developed at (I believe) MIT. Basically it's a PC bus with some custom
hardware to drive a DES chip at high speed. I don't recall the number but it
can do enough DES permutations fast enough that a brute-force attack on DES
is no longer out of the question for the key size. I gathered that if it were 
left going it would be able to do an exhaustive attack in about 3 hours, or
some reasonably short time.
