Recover license details using licenseRecovery DLL

This short blog post will show you how to recover product keys from a local computer using our licenseRecovery DLL.

This post focuses on C#, but it could just as easily be achieved in C++ or your preferred language.

using System;
using System.Text;
using System.Runtime.InteropServices;
namespace ConsoleApplication1
{
  class Program
  {
    [DllImport("licenseRecovery.dll", SetLastError=true)]
    private static extern void getLicenseKey(ref StringBuilder name, ref StringBuilder key);

    [DllImport("licenseRecovery.dll", SetLastError=true)]
    private static extern int numLicenseKeys();

    [DllImport("licenseRecovery.dll", SetLastError = true)]
    private static extern void setScope(bool isRemote, string remoteHost);

    static void Main(string[] args)
    {
      StringBuilder name = new StringBuilder(200);
      StringBuilder key = new StringBuilder(200);

      setScope(false, null);

      int num = numLicenseKeys();
      for (int i = 0; i < num; i++)
      {
        getLicenseKey(ref name, ref key);
        Console.WriteLine(name + "\t" + key);
      }
    }
  }
}
