CertificateFactorySpi is the abstract class Service Provider

Interface (SPI) for the CertificateFactory class. A provider

must implment all the abstract methods if they wish to

supply a certificate factory for a particular certificate

type. Ex: X.509
|

Certificate factories are used to generate certificates and
