/**
 * Key implementation classes.
 *
 * In PKCS#11, the components of private and secret keys may or may not
 * be accessible. If they are, we use the algorithm specific key classes
 * (e.g. DSAPrivateKey) for compatibility with existing applications.
 * If the components are not accessible, we use a generic class that
 * only implements PrivateKey (or SecretKey). Whether the components of a
 * key are extractable is automatically determined when the key object is
 * created.
