Activation API V1 - Location of the License

  1. Introduction
  2. SAAS Applications
  3. Device Applications

 

The Application will need to read/write the DNA License (a JSON encoded string) on the Device. (see below) The DNA License can be stored directly given that the DNA License itself is a signed object and exchanged during every API call.

The followng API’s return a DNA License that needs to be stored:

  • WEB_Activate()
  • WEB_Validate()
  • WEB_Reactivate()
  • WEB_Deactivate()
  • WEB_EvaluateNow()

When retrieving the DNA License before a WEB_Validate() or to retrieve any License info, always verify it’s SIGNATURE.

 

SAAS Applications

For a SAAS Application, the DNA License (a JSON encoded string) can be stored in a browser HTTP Cookie that will be registered for the domain of the SAAS Application.

The SAAS application would set the following license Cookie properties :

License Cookie Name any name Ex: softwareDNA
License Cookie Domain your domain.com domain name to allow using or not using the "www" to access your SAAS application Ex: .softworkz.com
License Cookie Expiry The expected (arbitrary) life of your SAAS Application (not the License expiry period) Ex: 365 days
License Cookie Value The DNA License JSON string

 

Device Applications

For a Device Application, the DNA License (a JSON encoded string) can be stored in any Read / Write storage / file system supported by the device and accesible by all Users on the device (typically a "Shared" or "Public" folder). Recommended locations for storing the License depend on the platform:

OS License Objective Recommended License Location
Windows One License per Computer C:\Users\Public\ <app_name> \ <app_name>.txt
Window Vista, 7, 8, 10 One License per User <Application.UserAppDataPath> <app_name> \ <user_name>_<app_name>.txt
MAC OSX All scenarios

Use the default location Package Contents -> MacOS.

Linux One License per Computer

/var/tmp/<app_name>/<app_name>.CDM
Linux One License per User

/home/<username>/.config/<app_name>/<app_name>.CDM
Android All scenarios getApplicationContext().getFilesDir() + File.seperator + <app_name>.txt
iOS All scenarios
