Class KeyManagerFactorySpi

java.lang.Object
  javax.net.ssl.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.

Since:

1.4

Method Detail

engineInit

protected abstract void engineInit(KeyStore ks,
                                   char[] password)
                            throws KeyStoreException,
                                   NoSuchAlgorithmException,
                                   UnrecoverableKeyException

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

See Also:

KeyManagerFactory.init(KeyStore, char[])

engineInit

protected abstract void engineInit(ManagerFactoryParameters spec)
                            throws InvalidAlgorithmParameterException

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 spec)

---

engineGetKeyManagers

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
