About ROT13
ROT13 (Rotate by 13 places) is a simple substitution cipher that replaces each letter with the letter 13 positions ahead in the alphabet.
Symmetric: The same operation both encodes and decodes the text.
Usage: Commonly used for light obfuscation of spoilers, puzzle solutions, and simple encryption where security is not a concern.
Example: "Hello" → "Uryyb"
