* Description:
|
|
sl@0
|
15 |
* This class implements the reference Crypto Token Hardware Abstraction
|
|
sl@0
|
16 |
* Interface (HAI). It is just intended to show how operations using
|
|
sl@0
|
17 |
* device keys can be performed using crypto token framework. In the
|
|
sl@0
|
18 |
* real world scenario, this HAI should be replaced by device drivers
|
|
sl@0
|
19 |
* by the licensees. In such a case, all the operations performed by
|
|
sl@0
|
20 |
* the replacing class would be performed in Kernel Space.
