KeyManagerFactorySpi

public abstract class KeyManagerFactorySpi extends Object

This class defines the Service Provider Interface (SPI) for the KeyManagerFactory class.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular key manager factory.

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

Public Constructors

public KeyManagerFactorySpi ()

Protected Methods

protected abstract KeyManager[] engineGetKeyManagers ()

Returns one key manager for each type of key material.

Returns

• the key managers

Throws

IllegalStateException	if the KeyManagerFactorySpi is not initialized

protected abstract void engineInit (ManagerFactoryParameters spec)

Initializes this factory with a source of key material.

In some cases, initialization parameters other than a keystore and password may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate ManagerFactoryParameters as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters implementation to obtain the needed information.

Parameters

spec	an implementation of a provider-specific parameter specification

Throws

InvalidAlgorithmParameterException	if there is problem with the parameters

See Also

• KeyManagerFactory.init(ManagerFactoryParameters)

protected abstract void engineInit (KeyStore ks, char[] password)

Initializes this factory with a source of key material.

Parameters

ks	the key store or null
password	the password for recovering keys

Throws

KeyStoreException	if this operation fails
NoSuchAlgorithmException	if the specified algorithm is not available from the specified provider.
UnrecoverableKeyException	if the key cannot be recovered
