iaik.pkcs.pkcs11.provider.Configurable

iaik.pkcs.pkcs11.provider.DelegateProvider

Direct Known Subclasses:

DefaultDelegateProvider

public abstract class DelegateProvider
extends Configurable

This id the interface to a delegate provider. A delegate provider provides delegation engines for several types of JCA and JCE engine; for instance, this includes signatures, hashes and ciphers.
