1 Affine Cipher (70 points) The Affine cipher is a cryptographic method for encrypting text such that it becomes unreadable to a party without access to the cryptographic key. The encryption and decryption operations are simple shifts of the alphabet letters in a cyclic fashion. Mathematically, for a key k= (a,b), the encryption and decryption are defined as: Encryption: c= (a +B) mod 26,1
