This ﬁle is used as an example of how to write an add-in service module for the Hewlett Packard Common Data Security Architecture (HP CDSA). This ﬁle just shows you the framework of creating a Data Storage Library (DL) and doesn’t perform any real operations. This framework can also be used to create a Certiﬁcate Library (CL) or Trust Policy Library (TP).
