suppose we want to send the message do not pass knowing that it has been enciphered using the affine cipher in the system we used it has the 26 letters a through z and 2 notations total numb 42367

A generalization of the Caesar cipher, known as the affine Caesar cipher, has the following form: For each plaintext letter p, substitute the ciphertext letter C : C=E([a, b], p)=(a p b) 26 A basic requirement of any encryption algorithm is that it be one-to-one. That is, if p ≠q, then E(k, p) ≠E(k, q). Otherwise, decryption is impossible, because more than one plaintext character maps into the same ciphertext character. The affine Caesar cipher is not one-to-one for all values of a. For example

SOLVED: Please explain clearly. I want to understand and tell me why you use any method you'll use it.Thanks.c. What is the decryption function for an affine cipher if the encryption function is c=15p 13/mod26?
