WebThe Atbash Cipher was originally a monoalphabetic substitution cipher used for the Hebrew alphabet. It is one of the earliest known subtitution ciphers to have been used, and is very simple. However, it's simplicity is also it's biggest pitfall, as it does not use a key. Hence every piece of plaintext enciphered using the Atbash Cipher uses the ... WebThe Mixed Alphabet Cipher is another example of a Monoalphabetic Substitution Cipher, and the way it works is exactly the same as with those already encountered, except in one way. The difference, once again, is how we create the ciphertext alphabet. Unlike all the other ciphers we have seen so far (Atbash, Pigpen, Morse, Shift and Affine), the ...
