Impressive work :) If you manage to get plaintext from just cyphertext, be sure to spread it around; I'd imagine a lot of people would be interested in it.
It doesn't quite do that yet. Given a section of known plaintext of about 50 characters it can find the original key used (or at least enough of the key to then turn the problem into a mono-alphabetic cipher).
