The Novell® Certificate Server Classes for Java (JPKI) map all functionality of the Novell Certificate Server C APIs. In other words, anything that can be done in the C APIs can also be done in the Java API. JPKI closely resembles the C API so the learning curve of those using the C functions should be short.
For more information about the Novell Certificate Server C APIs, see NDK: Novell Certificate Server Library for C Version 2 and NDK: Novell Public Key Infrastructure Toolbox. To understand conceptual about the implementation of Novell Certificate Server, see NDK: Novell Certificate Server APIs --- Overview.
