Shift Cipher - Computer Science and Statistics

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
