Overview of CCA verbs

Application and utility programs issue service requests to the cryptographic coprocessor by calling the CCA verbs. The term verb implies an action that an application program can initiate. The operating system code in turn calls the coprocessor physical device driver (PDD). The hardware and software accessed through the API are themselves an integrated subsystem.

Verb calls are written in the standard syntax of the C programming language, and include an entry-point name, verb parameters, and the variables for those parameters.

For a detailed listing of the verbs, variables, and parameters you can use when programming for the CCA security application programming interface (API), see the IBM CCA Basic Services Reference and Guide for the IBM® 4767 PCIe Cryptographic Coprocessors manual.
