WebModular Math and the Shift Cipher. The Caesar Cipher is a type of shift cipher. Shift Ciphers work by using the modulo operator to encrypt and decrypt messages. The Shift Cipher has a key K, which is an integer from 0 to 25. We will only share this key with people that we want to see our message. WebThe Caesar cipher was decrypted 800 years after its creation by an Arab mathematician Al-Kindi using the process of frequency analysis. The Caesar Shift Cipher used the English letters and shifted each letter by 3 places … WebFor additive ciphers given by Equation (5), the entire code is known, once we know the single number a.
