Another thinking step: most real-world DES keys are derived from hashes. Not (P)RNGs.

Hashes? Hashes of what?

The distributions are **not** uniform.

Then that's a wonderful weakness in the cryptosystem. Let's fix it.

The goal is to search the most likely keys first, and not all keys are created equally.

Any cryptosystem for which one can compute likely vs. unlikely keys has already been partially compromised. ______c_________________________________________________________________ Mike M Nally * IBM % Tivoli * Austin TX * How quickly we forget that mailto:m5@tivoli.com mailto:m101@io.com * "deer processing" and "data http://www.io.com/~m101/ * processing" are different!
