Without using a client side script, this page will encode or decode ROT-13 text typed or pasted in the left field below. ROT13 is a simplistic form of encryption. To be technically accurate, it is not really encryption, but encoding. It is most often used to prevent something from being read by accident. For example something that might give away the ending of a film, or a crude joke that might cause offense. Most electronic mail readers, and USENET news readers can decode ROT13.

The encoder/decoder on this web page uses the server side language PHP, so scripting does not need to be enabled. If you prefer a web page that uses client side Javascript, then click here.
