28  * Dummy Cryptographic Provider:

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