ca.randolf.security.Rot13

public class Rot13
extends Object

This class provides a static method that transforms data using the ROT-13 (also whimsically known as EBG-13) alphabetic rotation technique, typically used for the purpose of disguising information where strong encryption isn't required but some simple obfuscation is useful.

ROT13 (or EBG13) is an interesting case-insensitive symmetric obfuscation technique that rotates letters by circularly shifting them 13 positions within the confines of the English alphabet, while leaving all other characters unchanged. Where most messages are written using letters from the English alphabet, this method provides a useful disguise.
