Encoding
ROT13
Rotate every letter by 13 places.
Replaces each letter with the one 13 places further along the alphabet, wrapping from z back to a. Because the alphabet has 26 letters, applying it twice returns the original — so the same button encodes and decodes. It hides text from casual reading only; it is not encryption and offers no security.
