                          UnrecoverableKeyException

Initializes the KeyManagerFactory with the keystore and its password. This class creates an instance of the KeyManagerFactory created using the base algorithm / default algorithm and determines the key alias which should be used.

Specified by:

engineInit in class KeyManagerFactorySpi

Parameters:

keyStore - Keystore containing the private key

chars - Password to access the keyStore

Throws:

KeyStoreException

NoSuchAlgorithmException

UnrecoverableKeyException

engineInit

protected void engineInit(ManagerFactoryParameters managerFactoryParameters)
                   throws InvalidAlgorithmParameterException

Currently not implemented.

Specified by:

engineInit in class KeyManagerFactorySpi

Parameters:

managerFactoryParameters - ManagerFactoryParameters object containing the parametrs of the KeyManagerFactory.

Throws:

InvalidAlgorithmParameterException

engineGetKeyManagers

protected KeyManager[] engineGetKeyManagers()

Return the array with wrapped KeyManager instances.

Specified by:

engineGetKeyManagers in class KeyManagerFactorySpi

Returns:

Array of KeyManager instances

wrapKeyManagers

protected KeyManager[] wrapKeyManagers(KeyManager[] originalKeyManagers)

Wraps the KeyManager instances provided by the default KeyManager into the AliasKeyManager.

Parameters:

originalKeyManagers - The KeyMAnager instances as returned by the default algorithm

Returns:

Array of wrapped KeyManager instances

determineAlias

protected String determineAlias(KeyStore keyStore,
                                char[] chars)
                         throws KeyStoreException

Determines and validates the alias which should be used for the authentication. The alias is either taken from the System property or from the KeyStore.

Parameters:

keyStore - Keystore containing the private key

chars - Password to access the keyStore

Returns:

Alias of the key which should be used

Throws:

KeyStoreException
