ROT13 v1.0
ROT13 is a simple cipher used for obscuring text by replacing each letter with the thirteen places down the alphabet. Although a Caesar cipher, a method of encryption thousands of years old, ROT13 provides no real security and is not used for such. The algorithm is used on online forums as a means of hiding joke punchlines, puzzle solutions, movies and story spoilers and offensive materials from the casual glance. ROT13 has been described as the "Usenet equivalent of a magazine printing the answer to a quiz upside down".
This program is intended to be used with redirectors (it uses standard input/output).
