Determine what this cipher says, and the method of encryption, using the following hints:
- It is not a simple substitution cipher.
- Both the original plain text message and the encrypted message contain 270 characters (maybe with meaningless filler characters at the end).
- Only one rather simple method of encryption has been used.
- The encryption method is fairly robust. In other words, an error (while encrypting or decrypting) does not scramble the entire remaining message. Some very complicated ciphers have this problem.
- In the encrypted text, M and T appear most often, and R appears least often (I do not think these facts help at all).
- Both the original plain text and the encrypted message read from left to right.
- You might be able to guess the full text after determining only the first three words.
