CPACF support

Central Processor Assist for Cryptographic Functions (CPACF) must be configured and enabled on the system before you can use it.

Environment variables that affect CPACF usage
The CSU_HCPUACLR and CSU_HCPUAPRT environment variables control whether the CPACF is used for certain CCA functions.
Access control points that affect CPACF protected key operations
There are certain access points that enable the protected key feature.
CPACF operation (protected key)
These are details for Central Processor Assist for Cryptographic Functions (CPACF) usage by the host library.
CCA library CPACF preparation at startup
When the CCA library first starts up, it must take some initialization steps to prepare for using the Central Processor Assist for Cryptographic Functions (CPACF).
Interaction between the default card and use of protected key CPACF
While the CPACF can be used to encrypt and decrypt data in the absence of a CEX*C for protected key operations, a CEX*C is still necessary and it must be the allocated or default adapter for the thread doing the processing.
