About Caesar Cipher:

• ROT13: Shift by 13, self-reversing (encode = decode)
• Each letter is replaced by one that is N positions down the alphabet
• Non-alphabetic characters (numbers, symbols, spaces) are preserved
• Named after Julius Caesar who used it for secret correspondence
• Not secure for actual encryption - only for obfuscation/fun
