public abstract class KeyManagerFactorySpi extends Object
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.

 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.
