Class Signature

java.lang.Object
  org.tranche.security.Signature

All Implemented Interfaces:

java.io.Serializable

public class Signature
extends java.lang.Object
implements java.io.Serializable

Abstracts the absolute minimum required for a signature. This is what the Signature interface should require, but the initial code had that funky 'getEncoding()' concept.
