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. WebCaesar Cipher example. If you assign numbers to the letter so that A=0, B=1, C=2, etc, the cipher’s encryption and decryption can also be modeled mathematically with the formula: E n (c) = (x + n) mode 26. where x is the …
