Create one program with both parts below. Be sure to copy your program into a $.$txt file for submission, with the output at the bottom. DON'T USE ANY CONDITIONAL CONTROL FLOW DIRECTIVES.

As with last week, you can start with the project sample in the C:$\backslash$Irvine folder for each and then just change the names.

A$.$ Start with the encryption program in Section $6\mathrm{.}2\mathrm{.}4$ and revise it in the following manner: Create and encryption key consisting of multiple characters. Use this key to encrypt and decrypt the plaintext by XOR$($ing$)$ each character of the key against a corresponding byte in the message. Repeat the key as many times as necessary until all plain text bytes are translated.

B$.$ Use the following key: "AGZmy#$4".$ This is how the key would align with the plain text bytes:

T h i s i s a P l a i n t e x t m e s s a g e $($etc$)$

A G Z m y # $4$ A G Z m y # $4$ A G Z m y # $4$ A G Z m y # $4$ A

C$.$ Hard code the above key and the message. Do not prompt the user.
