/**

 * A private key.

 * The purpose of this interface is to group (and provide type safety

 * for) all private key interfaces.

 * <p>

 * Note: The specialized private key interfaces extend this interface.

 * See, for example, the {@code DSAPrivateKey} interface in

 * {@link java.security.interfaces}.

 * <p>

 * Implementations should override the default {@code destroy} and

 * {@code isDestroyed} methods from the

 * {@link javax.security.auth.Destroyable} interface to enable

 * sensitive key information to be destroyed, cleared, or in the case

 * where such information is immutable, unreferenced.

 * Finally, since {@code PrivateKey} is {@code Serializable}, implementations

 * should also override

 * {@link java.io.ObjectOutputStream#writeObject(java.lang.Object)}

 * to prevent keys that have been destroyed from being serialized.

 *
