Hi, Amigo. You know we're being followed. They're looking through our mail. So we need to encrypt our traffic. Implementing a Caesar cipher won't be hard for you. Let me remind you that this is simply a right-shift along the alphabet by the number of letters indicated by the key parameter.

Ran into an odd validator quirk with this one. You might be tempted, as I was, to put the reader argument inside a BufferedReader (i.e. BufferedReader buffReader = new BufferedReader(reader)). There is actually no reason to do this, but I did. And in testing, it work perfectly. However, the validator would not accept it. So if you're using a BufferedReader and aren't passing the last condition, that's probably why. Just use the reader - it works exactly the way you would want to use a BufferedReader for the purposes of this task.
