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