[VicPiMakers Projects] Jim's Challenge - Output 10 (caesar cipher)

Sun Oct 11 18:18:37 EDT 2020

Hello Jim,

Your instructions are unclear and we're just asking you to clearly address
the issue.

If you want our code to output the key used then either we assume the word
is the same or your next update also provides a new word in addition to a
new byte array.

Which is it?
