Interface ProtectorInterface

All Known Implementing Classes:

Protector

public interface ProtectorInterface

extends java.rmi.Remote

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

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.
