About the ROT13 Cipher
The ROT13 (rotate by 13 places) cipher is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the alphabet. It's a fun and classic way to obscure text, often used in online forums to hide spoilers, puzzle solutions, or punchlines. It is not a form of strong encryption.
