Class Memfrob

ca.randolf.security.Memfrob

public class Memfrob
extends Object

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

The word "frobnicate" is sometimes used to refer to this particular method of encryption, which simply performs an Exclusive Or on each byte with the number 42 (which is an interesting number if you're a fan of The Hitch Hiker's Guide To The Galaxy series by Douglas Adams).
