30  * Dummy Cryptographic Provider:
31  *
32  * This file implements a "dummy" cryptographic provider. It is implemented
33  * as a pseudo device driver.
34  *
35  */
36 
37 /*
38  * This driver implements a KEF provider with the following capabilities:
39  *
40  * - registration/unregistration with KEF
41  * - digest entry points
42  * - mac entry points
43  * - ctx management
44  * - support for async requests
45  * - cipher entry points
46  * - dual entry points
47  * - sign entry points
48  * - verify entry points
49  * - dual operations entry points
50  * - dual cipher/mac operation entry points
51  * - session management
52  * - object management
53  * - key management
54  * - provider management
55  *
56  * In order to avoid duplicating the implementation of algorithms
57  * provided by software providers, this pseudo driver acts as
58  * a consumer of the framework. When invoking one of the framework's
59  * entry points, the driver specifies the software provider to
60  * be used for the operation.
61  *
62  * User management: we implement a PKCS#11 style provider which supports:
63  * - one normal user with a PIN, and
64  * - one SO user with a PIN.
65  * These values are kept in the per-instance structure, and are initialized
66  * with the provider management entry points.
