C# HWID Login - Printable Version

Hi, this is just something someone wanted me to make for them a while back, I want to contribute to the community so I decided to share this.

Note: I got some of the code from online, but I can't remember where I got it from, but, credits to whoever wrote it.

Oh, btw, remember to import System.Management (using System.Management;) to be able to use the code shown below

Code

public string GetHDDSerial() // Public string that contains the variable of the hardware id string from URL.txt

        {

            ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

            foreach (ManagementObject wmi_HD in searcher.Get())

            {

                if (wmi_HD["SerialNumber"] != null)

                    return wmi_HD["SerialNumber"].ToString();

            }



            return string.Empty;

        }



       

        private void lgnhwid_Click(object sender, EventArgs e)

        {



            System.Net.WebClient Wc = new System.Net.WebClient();

            string pplbanned = Wc.DownloadString("Web URL"); // Banned Hardware ID's from server

            string pplallowed = Wc.DownloadString("Web URL"); // Whitelisted Hardware ID's from server



            if (pplbanned.Contains(GetHDDSerial())) // this if statement checks if the System Hardware ID matches with the string from the server

            {

                MessageBox.Show("You have been banned from '[name]'!", Text, MessageBoxButtons.OK, MessageBoxIcon.Error);

                Environment.Exit(-1);

            }

            else if (pplallowed.Contains(GetHDDSerial()))

            {

                MessageBox.Show("You're allowed to use '[name]', Welcome.", Text, MessageBoxButtons.OK, MessageBoxIcon.Information);

                HWDI_Login frm = new HWDI_Login();

                frm.Show();

                this.Hide();

            }

            else

            {

                MessageBox.Show("You're not whitelisted, make sure you sent Your" +

                    " Hwid to [name] and you bought our [product].", Text, MessageBoxButtons.OK, MessageBoxIcon.Warning);

                Environment.Exit(-1);

            }

            

        }



        private void HWDI_Login_Load(object sender, EventArgs e)

        {

            var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor");  // Get System Hardware id

            ManagementObjectCollection mbsList = mbs.Get();

            string id = "";

            foreach (ManagementObject mo in mbsList)

            {

                id = mo["ProcessorId"].ToString();

                break;

            }



            System_HWDI.Text = "System Hardware ID: " + id;

        }
