Description
Evaluation software that is restricted to a predetermined number of executions. The evaluation software can be distributed with a Sentinel SL key—for example, via a Web site or on a demo CD. Alternatively, it can be distributed with a Sentinel HL key, providing maximum security.
Using a Sentinel HL key for evaluation purposes is usually applicable for high-end software or for software with a high evaluation-to-purchase conversion rate.
When distributing the evaluation software with a Sentinel HL key, the type of key provided must be compatible with the licensing model that will subsequently be applied to the paid license. For example, if the paid license is a rental license, the key used must be a Sentinel HL Time or Sentinel HL NetTime key or must be a Sentinel HL key that supports V‑Clock.
Implementation
1.Select the executable file that you want to license, and determine by which Feature ID it will be identified.
2.Select your protection method:
•Envelope-based automatic implementation
Protect the executable file using Sentinel LDK Envelope, specifying its Feature ID.
•API-based automatic implementation
In your code, insert a Sentinel Licensing API Login call to the Feature ID.
3.Create the evaluation Product in Sentinel LDK-EMS and define the permitted number of executions for each Feature ID included in the Product.
4.Distribute the evaluation software with a Sentinel protection key programmed with the license.
5.Create the licensed Product in Sentinel LDK-EMS, defining the licensing terms for each Feature ID included in the Product.
6.When the end user purchases a fully-licensed product, update the Sentinel protection key
