ca.randolf.security.Rot47

public class Rot47
extends Object

This class provides a static method that transforms data using the ROT-47 ASCII rotation technique, typically used for the purpose of disguising information where strong encryption isn't required but some simple obfuscation is useful.

ROT47 is an interesting symmetric obfuscation technique that rotates a partial range of ASCII characters by circularly shifting them 47 positions within the range of ASCII character 33 through 126, while leaving all other characters unchanged. ROT47 provides a greater degree of obfuscation than either ROT13 or ROT13.5 do.
