The most advanced encryption available today. OK, just kidding, but Julius Caesar's day, this was hot stuff. Nowadays, it's so well known that it's used just for things like protecting a jokes punchline, or hiding potentially offensive text until the reader decides they want to see it. For that reason, many newsreaders have the ability to encode or decode rot13 text easily.
You may have a "rot13" command on your system, but if not, tr can do it:
#decode or encode tr "[a-mn-zA-MN-Z]" "[n-za-mN-ZA-M]"
