PrivateKey
public
interface
PrivateKey
implements
Key,
Destroyable
Known indirect subclasses
|
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.
