WebThe Vigenère cipher, or polyalphabetic shift cipher, was invented in 16th- century France, and for many centuries was considered unbreakable. Instead of choosing a single letter as the key, we choose a word or random string of letters. The encryption per character is the same as the Caesar cipher—letters are converted to numbers and added. 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.
