public interface PrivateKey extends Key, Destroyable
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 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 ObjectOutputStream.writeObject(java.lang.Object)
to prevent keys that have been destroyed from being serialized.
