Using the Slim Licensing API to Reduce File Size

Sentinel LDK Envelope with the Windows V3 engine enables you to build protected application files that use the Slim Licensing API. The Slim Licensing API omits the Integrated License Manager, which reduces the file size and memory footprint of the protected executable files.

By default, Sentinel LDK Envelope includes the Integrated License Manager in protected applications to handle licensing requests locally. To use the Slim Licensing API instead, select the EXTERNAL_LM_ONLY parameter in the advanced settings. When you select the EXTERNAL_LM_ONLY parameter, Sentinel LDK Envelope applies the Slim Licensing API, which relies on an external License Manager for all licensing operations.

When you use the Slim Licensing API, provide another License Manager to handle licensing on the end-user machine through one of the following methods:

>Deploy the External License Manager (hasp_rt.exe) in the same directory as the protected application.

>Install the Sentinel LDK Run-time Environment on the end-user machine.

You can download both the External License Manager and Sentinel LDK Run-time Environment from the Runtime Packages section of the Thales Support Portal for Sentinel LDK.
