Field rs_LoFlags contains lower byte of flags defining the properties of protected items. The following flags can be set (flag names listed below are used in Guardant API):
| Flag name | Value | Comment |
|---|---|---|
| nsafl_ID | 1 | |
| nsafl_GP_dec | 2 | Decrements GP counter on each algorithm call. Once GP counter reaches 0, algorithm is automatically deactivated and returns error code GrdE_InactiveItem in response to further calls |
| nsafl_GP | 4 | Not used for modern dongles |
| nsafl_ST_III | 8 | Flag should be set for modern dongles |
| nsafl_ActivationSrv | 16 | Activation service available |
| nsafl_DeactivationSrv | 32 | Deactivation service available |
| nsafl_UpdateSrv | 64 | Password-protected service for changing data in items rs_K[] available (GrdPI_Update function supported) |
| nsafl_InactiveFlag | 128 | Algorithm/cell is inactive at the moment. Operations GrdTransform, GrdPI_Read, GrdPI_Update not available |
| Flag name / Algorythm type | AES128,GSII64 | ECC160 | SHA256 | Loadable Code | Protected Item |
