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