Offline License Validation

I am trying to implement Licensing on a .NET Core 7 server based application. 

Currently I have 2 forms

• Upload the QlmLicense xml file that I have received (Root node: QuickLicenseManager)
• Send ActivationKey and ComputerID to our API to allow license activation

At the moment I am always getting a status of EKeyInvalid. 

The QlmLIcense file and the Public key are stored in a database 

The LicenseValidator constructor runs the following code without error

license.ReadLicenseXml(licenseXml.ToString(), string.Empty, out errorMessage);
license.RsaPublicKey = publicKey;
if (license.ValidateSettingsContent(licenseXml.ToString(), out errorMessage) == false)

{
    throw new Exception(errorMessage);
}

So far I have tried the following NUGET packages without success

• QLM.QlmLicenseLib
• QLM.QlmLicenseLibNetStd
• QLM.QlmLicenseLibNetCore

I have suspicion that I am missing the settings.xml file generated by the Protect Your App Wizard. But I have tried the Protect My Application in the Desktop application and that doesn't generate a settings.xml file when I go through the wizard.

  Hi William,

  1. Can you clarify which API call is returning EKeyInvalid?

  2. Can you send attach the License XML file?

  Since this forum is public, I would recommend that you open a ticket by emailing support@soraco.co and then share private files within the ticket.

  Regards,

  John
