For a dongle to work with a protected application according to the established protection scheme, it has to be previously programmed.GrdUtil.exe utility serves for programming Guardant dongles.

GrdUtil.exe utility provides a wide range of features for editing the dongle’s memory and preparing data for protection:

• Working with the dongle’s mask (an external memory image) the utility is able to:
  • Create/edit/delete dongle memory fields
  • Work with hardware algorithms
  • Work with protected items
  • Work with LMS table
  • Work with dumps, numbers, strings and counters
  • Set hardware locks for reading/writing into memory fields
  • Save mask in an internal database or in a separate file
  • Retrieve information on connected dongles

  • Search for dumps based on defined criteria and prepare the list of search results
  • Remote and local update of dongle memory of any dump
• Preparation of data for applications protection:
  
  • Generate arrays of questions and answers of hardware algorithms
  • Encrypt/decrypt data using algorithms
  • Verify the results of Guardant API functions execution with defined parameters
