rot13
/rot ther'teen/ [Usenet: from "rotate alphabet 13 places"], v. The simple
Caesar-cypher encryption that replaces each English letter with the one 13
places forward or back along the alphabet, so that "The butler did it!" becomes
"Gur ohgyre qvq vg!" Most Usenet news reading and posting programs include a
rot13 feature. It is used to enclose the text in a sealed wrapper that the
reader must choose to open - e.g. for posting things that might offend some
readers, or spoilers. A major advantage of rot13 over rot(N) for other N is that
it is self-inverse, so the same code can be used for encoding and decoding.
