Generic cryptographic device driver
The generic cryptographic device driver (zcrypt) supports cryptographic coprocessor and accelerator hardware. Cryptographic coprocessors provide secure key cryptographic operations for the IBM® Common Cryptographic Architecture (CCA). Cryptographic coprocessors also support Enterprise PKCS #11 (EP11). CCA and EP11 coprocessors operate as Hardware Security Modules (HSMs).
Some cryptographic processing in Linux® can be offloaded from the CPU and performed by dedicated CCA or EP 11 coprocessors or accelerators. Several of these CCA or EP 11 coprocessors and accelerators are available offering a range of features. The generic cryptographic device driver (zcrypt) is required to use any available cryptographic hardware for processor offload.
