Discussion / Question . "ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the letter 13 letters after it in the alphabet. The following is the output: If we enter the message URYYB and run that, it turns back into HELLO: This is important because there are quite a few cryptographic functions that have this property; where you encrypt something once and encrypt it again, you reverse the process.
