A private key. The purpose of this interface is to group (and provide type safety for) all private key interfaces.
Note: The specialized private key interfaces extend this interface.
See, for example, the DSAPrivateKey interface in
java.security.interfaces.
Implementations should override the default destroy and
isDestroyed methods from the
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 PrivateKey is Serializable, implementations
should also override
java.io.ObjectOutputStream.writeObject(java.lang.Object)
to prevent keys that have been destroyed from being serialized.
