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.

Params:
  • spec – an implementation of a provider-specific parameter
         specification
Throws:
