For your amusement:
The number 2^56 of DES keys is quite close to the number of 3"x5" index
cards that it takes to cover the surface of the earth (ocean included).
A Pentium searching 200,000 keys/second is like driving a car at 70 mph
and checking all the index cards in a 200-foot wide swath. At this speed,
it takes two weeks just to go around the earth once.
Back to me.
