Such possibilities became available thanks to protected items technology with hardware algorithms being a special case of such technology.

If Activation service is on in the algorithm properties, this algorithm can be made active by accessing it with a special Guardant API function from within the application or by executing the update procedure. After activation you can execute all preprogrammed actions with the algorithm: perform encryption, read algorithm descriptor contents, update specific areas of descriptor, deactivate algorithm. Examples of use
GrdPI_Activate function serves for activating an algorithm from within the application. Setting the Activation flag turns on the service and enables the following options (see information below for more details):
Also another option common for all services appears:
After turning on Activation service set the activation password, define its type and the number of password entry attempts. If the application protection scheme presumes that the algorithm must be initially deactivated, Set inactive status flag is required. The inactive algorithm will appear in palegray font in Mask Editor. |
