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