1. A generalization of the Caesar cipher, known as affine Caesar cipher, has the following form: For each plaintext letter p substitute the cipher text letter C: C (ap b) mod 26 Using a = 5, b = 8, find out the cipher text to encrypt the following message: affinecipher 2. Using the Playfair matrix as given below, encrypt the following message: Must see you over Cadogan West MFH IJK UNO P Q ELARG DST B C 3.
