Class Wipe

java.lang.Object
  core.crypto.Wipe

public class Wipe
extends Object

This class is used to clear confidential data structures from memory I'm not sure if this is necessary, but it won't hurt. Since we are usually operating on volatile memeory I think two loops are enough. We don't want to waste too much performance.
