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.

    * #### engineInit  
    protected abstract void engineInit​([KeyStore](../../../java/security/KeyStore.html "class in java.security") ks,  
                                       char[] password)  
                                throws [KeyStoreException](../../../java/security/KeyStoreException.html "class in java.security"),  
                                       [NoSuchAlgorithmException](../../../java/security/NoSuchAlgorithmException.html "class in java.security"),  
                                       [UnrecoverableKeyException](../../../java/security/UnrecoverableKeyException.html "class in java.security")  
    Initializes this factory with a source of key material.  
    Parameters:  
    `ks` \- the key store or null  
    `password` \- the password for recovering keys  
    Throws:  
    `[KeyStoreException](../../../java/security/KeyStoreException.html "class in java.security")` \- if this operation fails  
    `[NoSuchAlgorithmException](../../../java/security/NoSuchAlgorithmException.html "class in java.security")` \- if the specified algorithm is not available from the specified provider.  
    `[UnrecoverableKeyException](../../../java/security/UnrecoverableKeyException.html "class in java.security")` \- if the key cannot be recovered  
    See Also:  
    [KeyManagerFactory.init(KeyStore, char\[\])](../../../javax/net/ssl/KeyManagerFactory.html#init-java.security.KeyStore-char:A-)  
    * #### engineInit  
    protected abstract void engineInit​([ManagerFactoryParameters](../../../javax/net/ssl/ManagerFactoryParameters.html "interface in javax.net.ssl") spec)  
                                throws [InvalidAlgorithmParameterException](../../../java/security/InvalidAlgorithmParameterException.html "class in java.security")  
    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](../../../java/security/InvalidAlgorithmParameterException.html "class in java.security")` \- if there is problem with the parameters

    * #### engineGetKeyManagers  
    protected abstract [KeyManager](../../../javax/net/ssl/KeyManager.html "interface in javax.net.ssl")[] engineGetKeyManagers​()  
    Returns one key manager for each type of key material.  
    Returns:  
    the key managers  
    Throws:  
    `[IllegalStateException](../../../java/lang/IllegalStateException.html "class in java.lang")` \- if the KeyManagerFactorySpi is not initialized
