Usage
What is ROT13
ROT13 ("rotate by 13 places") is a special case of the Caesar cipher that replaces each letter in the alphabet with the 13th letter after it. Because the Latin alphabet has 26 letters, ROT13 is its own inverse: applying ROT13 to the ciphertext restores the plaintext.
Use Cases
Commonly used to hide spoilers, punchlines, or offensive content. It provides no real security and is only a simple form of obfuscation; it should not be used to encrypt sensitive information.
