Re^2: z340crack : A Tool For Brute-Force Cracking The Zodiac Serial Killer's Z340 Cipher.

I now realize the joke is on me. There is no place in the while ($z>=0) loop that $z will ever get set to below 0. No wonder I've been running this now for 45 days without end!

This script will run forever, producing output and dumping a key when 3 or more "signal words" are found in the noise. Seeing upwards of 3 would yeild a key that would be close enough to a solution that the remainder could be deciphered by human eyes. It's a comprimise between the need for building a very fast engine, and the need to have a strict dictionary check of every possible word. Given the enormous keyspace we're dealing with, it's mathematically unlikely to yeild a full solution in our lifetime. This tool attempts to render partial solutions which warrant human appraisal.
