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) and the Enterprise PKCS#11 feature (EP11). CCA and EP11 coprocessors operate as Hardware Security Modules (HSMs).
Some cryptographic processing in Linux® can be offloaded from the processor and performed by CCA or EP11 coprocessors or accelerators. Several of these CCA or EP11 coprocessors and accelerators are available offering a range of features. The generic cryptographic device driver (zcrypt) is required to use any available cryptographic hardware.
