HWID System With Online/Offline Protection

[Dark L3g3nd]

Hi,

Some of this code is from other people and I've just compiled it together and changed to C# as well as adding online/offline protection. There's two ways to doing this. You will need to host a database.txt file on a website which contains the valid HWID's.

What is a HWID?

http://www.webopedia.com/TERM/H/HWID.html

First one :

Step : 1

This is to retrieve the HWID of the computer and paste it into a textBox.(button1_Click) Paste it inside the { and the } when you double click the Get HWID button.

string cpuInfo = string.Empty;
    ManagementClass mc = new ManagementClass("win32_processor");
    ManagementObjectCollection moc = mc.GetInstances();

    foreach (ManagementObject mo in moc)
    {
    if (string.IsNullOrEmpty(cpuInfo))
    {
    cpuInfo = mo["ProcessorID"].ToString();
    break;
    }

    }
    textBox1.Text = cpuInfo;

Step : 2

This is to retrieve the list of HWID's from your database.txt file and check it to the current computers.(button2_Click) Paste it inside the { and the } when you double click the Check/Login button.

try
    {
    string cpuInfo = string.Empty;
    WebClient webClient = new WebClient();
    string strings = null;
    strings = webClient.DownloadString("http://website.com/Database.txt");
    webClient.Dispose();

     if (strings.Contains(cpuInfo))
    {

     // If the HWID is in the file then it will return this.    MessageBox.Show("HWID Valid", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
    this.Hide();
    Form1 frm1 = new Form1();
    frm1.ShowDialog();
     }
    else
    {
     // If the HWID isn't in the file then it will return this.
    MessageBox.Show("HWID Invalid", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
    this.Close();
    }
    }
    catch (Exception)
    {
    // If not connected to the internet or can't connect to the site then it will return this.
    MessageBox.Show("Unable To Retrieve HWID", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
    this.Close();
    }

Second One :

Step : 1

This is to retrieve the HWID of the computer and paste it into a textBox.(button1_Click) Paste it inside the { and the } when you double click the Get HWID button.

string cpuInfo = string.Empty;
    ManagementClass mc = new ManagementClass("win32_processor");
    ManagementObjectCollection moc = mc.GetInstances();

    foreach (ManagementObject mo in moc)
    {
    if (string.IsNullOrEmpty(cpuInfo))
    {
    cpuInfo = mo["ProcessorID"].ToString();
    break;
    }

    }
    textBox1.Text = cpuInfo;

Step : 2

This will handle the checking of if you are connected to the internet.

[DllImport("wininet.dll")]
private extern static bool InternetGetConnectedState( int out Description, int ReservedValue ) ;

public static bool isConnectedToTheInternet( )
{

    int Desc ;
    return InternetGetConnectedState( out Desc, 0 ) ;

}

Step : 3

This is to retreive the list of HWID's from your database.txt file and chek it to the current computers.(button2_Click) Paste it inside the { and the } when you double click the Check/Login button.

if (!isConnectedToTheInternet()) //Checks if it isn't connected to internet
    {
    MessageBox.Show("Unable To Retrieve HWID", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
    this.Dispose();
    } else
    { //Downloads the database.txt file.
    string cpuInfo = string.Empty;
    WebClient webClient = new WebClient();
    string strings = null;
    strings = webClient.DownloadString("http://website.com/Database.txt");
     webClient.Dispose();

    if (strings.Contains(cpuInfo))//If it contains the HWID in the database.txt file.
    {
    MessageBox.Show("HWID Valid", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
    this.Hide();
    Form1 frm1 = new Form1();
    frm1.ShowDialog();
    } 
    if (!strings.Contains(cpuInfo))//If it doesn't contain the HWID in the database.txt file.(Could use else method)
    {
    {
    MessageBox.Show("HWID Invalid", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
    this.Dispose();
    }
    }

    }
  }

That's it, I recommend the first one for beginners or novice users and second for more experienced users as you have more control.

Enjoy!

I used to use a bot that was protected by something similar to these. Are these good for selling programs?
