WebAffine Ciphers Before, when we talked about the Caesar cipher, we used the formula m (mod 26) where m stood for a letter in the alphabet. Now, we will generalize this cipher to mx + y (mod 26) where m stands for a letter in the alphabet (counting from A = 0 to Z= 25) and x,y are any natural number. This is called the Affine cipher.
