There we go!

I figured out that it was XOR on my way home, but I wasn't quite sure how to apply it. Plus, I forgot about the reverse function which is what I need in order to strip the end of the string. Instead, I was going to pad left the strings to make them the same length.

Thank you for your answer. I'll try it out when I get to work tomorrow.
