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. For example, 'A' becomes 'N', 'B' becomes 'O', and so on.
What makes ROT13 special is that it's its own inverse - applying ROT13 twice will get you back to the original text. This happens because the English alphabet has 26 letters, and 13 is exactly half of 26.
ROT13 is not meant for security but is often used in online forums to hide spoilers, puzzle solutions, or punchlines. It provides a way to obscure text while making it easily accessible to those who want to read it.
