public class Protector

extends java.rmi.server.UnicastRemoteObject

implements ProtectorInterface

The implementation of ProtectorInterface. This class depends on Mercury API. Based on the KeyPairBox instance, provide the service for signing and encrypting the object and vice versa.

The private key and public key to be used for the service must reside in the KeyPairBox instance, which is specified at the constructor. The object to be signed and encrypted must implement Serializable, Signed and Sealed.
