MonoDecrypt uses pattern matching and its knowledge about character frequencies in order to decrypt messages encoded with a monoalphabetic substitution cipher. MonoDecrypt can decrypt texts of any language, as long as it has sufficient information about the language. Depending on the information you give it, the tool decrypts about 50%-100% on its own. Then you can decrypt the remaining data by filling the gaps or correcting bad guesses. MonoDecrypt can also encrypt texts using monoalphabetic substitution.
