Problem 1 (Affine Cipher): An affine cipher has the form c = (am b) n. Suppose m is aninteger between 0 and 25, each integer representing a letter.1. Let n = 26, a = 3, and b = 123. What is the ciphertext corresponding to the phraseTHIS IS A CIPHER MESSAGE2. A requirement for a cipher is that every plaintext letter corresponds to a different ciphertextletter. If a and b are not relatively prime to n, does the affine cipher meet this property? Ifso, prove it. Otherwise, present a counterexampl
