ROT-13

ROT-13 (Rotate by 13 places) is a simple letter substitution cipher that replaces each letter in a message with the letter 13 places ahead or behind it in the alphabet. It is a special case of the Caesar cipher, with a fixed shift of 13.

Encrypting text with ROT-13 is a straightforward process that provides a basic level of encryption. It is commonly used as a form of obfuscation or to hide spoilers in online forums. The encryption algorithm is symmetric, meaning that applying ROT-13 twice to a piece of text will yield the original message.

To encrypt text with ROT-13, each letter in the message is substituted with the corresponding letter 13 places ahead (or behind) it in the alphabet. Non-alphabetic characters, such as numbers or punctuation, remain unchanged. The encryption is case-insensitive, so uppercase letters are converted to uppercase and vice versa.

While ROT-13 provides minimal security and can be easily decrypted, it can still serve as a fun and quick way to hide information or challenge readers to decipher the message. For stronger encryption, more advanced algorithms should be used.
