About ROT13
ROT13 ("rotate by 13 places") is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the alphabet.
It's a special case of the Caesar cipher and is its own inverse - the same algorithm is used for both encoding and decoding.
Example: "HELLO" becomes "URYYB" and "URYYB" becomes "HELLO" when decoded.
💡 Pro Tip: ROT13 is commonly used in online forums to hide spoilers, punchlines, and offensive content.
