An encryption scheme similar to ROT13, but twice as secure.
This sentence was originally encrypted using ROT26. If you can read it, you have successfully decrypted it.
Some goofy encryption system that replaces each letter with the 26th one away. In the English alphabet, it replaces the letter with the same letter.

1: You are stupid
2: No you're stupid
1: How did you know what I said, I used ROT26
2: You really are stupid...
