System z kernel features - Crypto

•

Support for large random numbers (kernel 2.6.25)

•

Allow user space applications to access large amounts of truly random data.

The random data source is the built-in hardware random number generator on

the CEX2C cards.

•

Generic algorithm fallback (kernel 2.6.25)

•

Use software implementation of the in-kernel crypto library for key lengths not

supported by hardware

•

Without the fallback support it is not possible to use in-kernel crypto with a key

length that is not supported by the hardware module.
