NOTE: NOT VERY ACCURATE. This will attempt to solve a (normally very long) cipher into proper English. Normally it only gets 4 or 5 letters correct, but... yeah, it's the best I could make.
Me List sorters How it works: It measures how common letters are used in the coded text, then compares with how common English letters are used. Then it attempts to decode. Very good at finding these letters: E, T, A, and for some reason K. Other ones are not promised or likely. For better results try to decode huge blocks of text.
