In a previous post an ex member asked about multiplicative inverses & ciphers I am now curious as to how this works. A multiplicative cipher is defined on Z26 by the rule M5(m) = 5×26 m. Messages are in English are coded numerically where the alphabet is mapped to a number. A = 1 B = 2. . . . . . z = 26 Could you encipher any letter or word using M5 (that is, find the ciphertext for this message) as I'm curious now. Thank you
