API Implementation

Recommended Steps for Protecting Applications with API

To protect your application with API, we recommend the following steps:

  1. Familiarize yourself with the API (see integration, use and Smarx Compendium chapter 10). Choose a suitable API and review the sample code for your environment.
     
  2. Check our notes on secure integration in the Smarx Compendium chapter 17.
     
  3. The easiest way to configure the CRYPTO-BOX for your application with the required protection and licensing setting is to use it with the Smarx Application Framework (SxAF, see Smarx Compendium chapter 4.5):
     
    • Start SxAF on your computer:
      Select “SxAF Client” in the start menu under MARX Smarx OS PPK.
    • Create a new SxAF project and enter "Implementation with API" as the project type.
    • Select the project-specific values for the CRYPTO-BOX, e. g. label and AES keys.
    • Select the license options for your by defining one or more partitions for data objects with license information. These can be expiration dates, counters, network licenses and/or customer specific memory objects (see Smarx Compendium chapter 4.5.5 for further details).
    • Use the “CB Format” option in SxAF to format your CRYPTO-BOX units with the project settings. You can optionally export your project settings to a XML file in order to use the command line tools (further information can be found in Chapter 4.9 of the Smarx Compendium).
       
  4. If you want to update your CRYPTO-BOX later at the end-user, use the Remote Update Tool and send the update together with the CRYPTO-BOX to your end-user (see Smarx Compendium Chapter 4.10.3 for more information).
     
  5. Test all licensing options carefully.
     
  6. Send your protected application togehter with the CRYPTO-BOX and the additional files such as drivers and, if necessary network server for network licensing).

MARX provides an easy-to-use redistribution setup.
