WebAug 27, 2024 · Another version of this Caesar Cipher is ROT 13 – which rotates (shifts) the letter by 13 instead od 3. It has been reported that ROT13 was used by Netscape Communicator in 1990s to store user’s password. It’s worth notice that Caesar (ROT13 (x)) = ROT16 (x), because Caesar is adding +3, ROT is +13. Common joke in cryptology … WebAn encryption based on a formula of the type c p +a mod 26 (5) is called a shift code because we can think of shifting the alphabet over a spaces to do the coding. Because of this equation, it is also called an additive code or cipher. What makes it relatively easy to decipher is that we only have to know how one letter is enciphered to
