WebThe Atbash cipher is a simple monoalphabetic substitution cipher originally used to encrypt the Hebrew alphabet. With this cipher, we simply take the alphabet and map it to its reverse. As such, when the Atbash cipher is used in English A … Webare needed in order that p and c can be assigned a letter of the alphabet. We can illustrate these equations as follows: If the ciphertext letter is F, then we have c =6, since F is the 6th letter of the alphabet. Using equation (4), we nd p c − 2 mod 26, or p 4 mod 26. So the plaintext must be D, the fourth letter of the alphabet. On the other
