The C API

ICSF provides a PKCS #11 C language application program interface (API). This topic highlights the differences between the z/OS® API and the PKCS #11 V2.20 specification. To use this API, you must be familiar with both the PKCS #11 specification and the information in this topic.

All manifest constants specified in this chapter can be found in the csnpdefs.h include file and (with the exceptions noted) in the PKCS #11 specification.
