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
ROT13 - तकनीकी विवरण
ROT13 shifts each letter by 13 positions in the alphabet. Since there are 26 letters, applying ROT13 twice returns the original text. It was commonly used to hide spoilers in forums.
