LicenseServer is a product that we have developed internally to enforce license instances of desktop applications.
We built this product to manage the licensing of our desktop products safely. LicenseServer is a web API that returns the signed, encrypted certificate that then lives on the customer’s computer. If they attempt to tamper with the license, the sign will break, and it will go back to the server to get a fresh copy of the license. The license does contain important information about the application, such as the validity or if it is a trial what the end dates are.
It is both signed by a signing certificate and protected by a private, public key. All the data is hidden behind a firewall with limited access only to the web API. We have not released this as an actual product outside of our internal use, but if you have interest in License Server, please contact us at email@example.com
