Clearly, this cipher will require an alphabet of more than 26 letters, as each letter needs at least one ciphertext letter, and many need more than this. The standard way to do this is to include the numbers in the ciphertext alphabet, but you can also use a mixture of uppercase, lowercase and upside down letters.

The Atbash cipher is a simple substitution cipher that relies on transposing all the letters in the alphabet such that the resulting alphabet is backwards.Encryption. 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. The NATO phonetic alphabet is an alphabet created for oral telecommunications, in order to spell words correctly.
