Explore how information can be encrypted to securely transfer between systems, develop a simple program that can encrypt$/$decrypt a file. The program should take as its first command line argument the file to be encrypted$/$decrypted$.$ The second command line argument should be the encrypted$/$decrypted file to create. The third command line argument should be the password to use during the encryption$/$decryption process. Use the attached program Project$2$b$.$cpp as a starting point. Implement the processFile$()$ method to perform the encryption$/$decryption$.$
