General-purpose Guardant API functions
General-purpose functions allow implementing service operations related to initialization, setup and deinitialization of Guardant API as well as performing the main operations with dongles:
- Search for a dongle meeting specified search criteria
- Initialize the dongle memory
- Read data from dongle memory
- Write data into dongle memory
- Set read/write locks on dongle memory
- Encrypt information using dongle hardware algorithms
