Manage license node-locking

To use license node-locking, provide the hardware fingerprint of the intended On-Prem Qt License Server or Offline Qt License Server host computer to Qt. Ask your Qt contact for more information.

The generated hardware fingerprint is unique to the Qt License Server host computer, which means that it locks the license file for the particular host running On-Prem Qt License Server or Offline Qt License Server.

Send the generated fingerprint via email to Qt Support for validation. You receive a new entitlement.json file that lists valid licenses with the fingerprint attached and hashed to each license. The new license file contains both the license information and the associated fingerprint.

When Qt License Server starts, the entitlement.json file is automatically imported. A license that includes a fingerprint is imported if the fingerprint matches the Qt License Server host computer.

Generate fingerprints

To generate a fingerprint from the command line with qt-license-server, enter:

./qt-license-server generate-server-fingerprint

.\qt-license-server.exe generate-server-fingerprint
