In this assignment you'll write a program that encrypts the alphabetic letters in a file using the Hill cipher where the Hill matrix can be any size from 2x2 up to 99. Your program will take two command line parameters containing the names of the file storing the encryption key and the file to be encrypted. The program must generate output to the console (terminal) screen as specified below. 1.1 Command line parameters 1. Your program must compile and run from the terminal command line. 2. Input the required file names as command line parameters. Your program may NOT prompt the user to enter the file names. The first parameter must be the name of the encryption key file, as described below. The second parameter must be the name of the file to be encrypted, also described below. The sample run command near the end of this document contains an example of how the parameters should be entered and processed. 3. Your program should open the two files, echo the processed input to the screen, make the necessary calculations, and then output the ciphertext to the console (terminal) screen in the format described below. Note If the plaintext file to be encrypted doesn't have the proper number of alphabetic characters to match the key size, pad the last block as necessary with the lowercase letter x. Make sure that all the input characters are lower case only. 1.2 Formats 1.2.1 Encryption Key File Formats The encryption key file will contain a single positive integer, n where (1
