It's not so much of a decryption, but a brute force attack on the session
key. You get your machine to try every different variation of 0's and
1's, for a number of bits, and keep working up. This is why a larger bit
size of key is better, as it will withstand an attack for longer.
To split it up, you tell each machine to work on a different section of
the guesses. For example, machine 1 goes from 0 to 0xffffffff and machine
2 goes from 0x100000000 to 0x1ffffffff. I'm sure you get the idea.
