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. WebCiphers use algorithms to transform a message into an apparently random string of characters.
