I need assistance with this as it has been awhile since I have done programming. Using any programming language (c or java preferred). Create a program that can encrypt and decrypt using the affine cipher as described below:

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) = (ap+b) mod 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, for a = 2 and b = 3, then E([a, b],0) = E([a, b], 13) = 3
