Crypto Hardware Support

The configuration file has a keyword, UseCryptoHardware, that governs the use of crypto hardware. The available support depends on the processor model and on the devices that are installed. In the table below, CPACF is standard on z890 and z990 machines but is not available on other machines. The CCA column includes the following devices: CCF, PCICC, PCIXCC and CEX2. The Accelerator column includes the PCICA device, PCIXCC and CEX2.

	CPACF	CCA	Accelerator
3DES-CBC	x	x
SHA1	x
RNG		x
[RSA]		[x]	[x]
[DH]			[x]
RACF certificate		x

If any crypto hardware devices are to be used, the machine or the LPAR must be enabled for cryptography.

Note: The current release has no hardware support for RSA or DH.
