Crypto Hardware Support
The configuration file has a keyword,
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.
FIPS mode is enabled when the IBM crypto hardware is used. FIPS mode is
currently not available in SSH Tectia Server for IBM z/OS when the software crypto library is used.
Thus, if the
UseCryptoHardware keyword defines algorithms for
hardware acceleration, the FIPS mode is automatically enabled for the
defined algorithms and cryptographic operations are performed according to
the rules of the FIPS 140-2 certification standard. In all other
configurations, FIPS mode is disabled.
