Class SimpleKey

java.lang.Object
  com.antelmann.util.SimpleKey

All Implemented Interfaces:

SynchronousKey

public class SimpleKey
extends Object
implements SynchronousKey

A very simple encryption algorithm for demonstration purposes only. It is far from being safe, but it will require anyone to at least put some manual effort into reading any message that uses Encoded objects using this algorithm when send over the Internet. (And BTW, since this is open source, it would be a BAD IDEA to use this synchronous key for anything else but a demonstration!)

Method Summary

byte[]	decode(byte[] encrypted)
void	decode(InputStream in, OutputStream out) decodes the given InputStream into the given OutputStream
