Sentinel Hardware Keys Developer’s Guide

■

Build the license template using the instructions described in the
Sentinel Keys Toolkit Help.

■

You can now test your protected application. We recommend testing
your application to verify that it executes correctly with the
appropriate Sentinel Key both attached and missing.

Note:

If you are testing your protected application in network environment,
make sure to restart the Sentinel Keys Server.
