What is ROT13?

ROT13 (rotate by 13 places) is a simple letter substitution cipher that replaces each letter with the letter 13 positions after it in the alphabet. Since the English alphabet has 26 letters, applying ROT13 twice returns the original text — making it its own inverse. ROT13 provides no cryptographic security; it's merely used to obscure text from casual reading.
