37 .Nd hardware crypto access driver
44 driver provides a device-independent framework to support
45 cryptographic operations in the kernel.
48 driver provides userland applications access to this support
52 This node primarily operates in an
54 based model, permitting a variety of applications to query device capabilities,
55 submit transactions, and get results.
