I'm not going to even bother unless you tell me something

What SORT of encryption is it?
Single replacement? Sliding replacement? Seed based adjustment?

Sure, its possible to decrypt something on the order of Enigma or Indigo, but even they had some hints. They also had quite a bit more than one bit to work with.

Let's be honest, with only one encrypted string the best anyone around here is gonna get is a single replacement.
