WebEncryption. Encryption using the Shift Cipher is very easy. First we must create the ciphertext alphabet, which as discussed above is simply found by 'shifting' the alphabet to the left by the number of places given by the key. Thus a shift of 1 moves "A" to the end of the ciphertext alphabet, and "B" to the left one place into the first position. WebApr 9, 2024 · The Caesar Cipher is what is known as a “substitution cipher” or “shift cipher.”. It works by changing each letter within a message three letters, to the right. For example, an A in a message would become a D, and a B would be written as an E. The number of letter places that get shifted is called the key.
