Interface PrivateKey

All Superinterfaces:

Destroyable, Key, Serializable

All Known Subinterfaces:

DHPrivateKey, DSAPrivateKey, ECPrivateKey, RSAMultiPrimePrivateCrtKey, RSAPrivateCrtKey, RSAPrivateKey

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.
