ROT13 encoder / decoder

Instructions

Use this form to encrypt a message using the ROT13 algorithm. The ROT13 encoding simply shifts every letter by 13 places in the alphabet while leaving non-alpha characters untouched. Encoding and decoding are done by the same function, so you can use this both to encode a message, and to decode an ROT13 encoded message.

Then paste the message into an e-mail, and no one except you (and the NSA and the CIA and the FBI) and a person who knows about ROT13 (or this page) will be able to read it. Ooohh... pretty kewl.
