Class RsaDigitalNotary

java.lang.Object

craterdog.security.RsaDigitalNotary

All Implemented Interfaces:

Notarization

public final class RsaDigitalNotary
extends Object
implements Notarization

This class can be used to sign and verify digital notarized documents using a private/public key pair. It uses RSA-2048 for asymmetric (public/private) key signature generation and verification.
