Just something I quickly wrote up. Basic programming, sadly it's technique is horrible as I could have done a lot better.

This is essentially scrap code.

    using System;using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Net;

using System.Security.Cryptography;





namespace Program_Verify

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }





        string UserLocalName;

        string InvalidCharacters = " _-ACEGIKMOQSUWY";

        bool InvalidChar = false;

        string IDBuilder = "";

        string NewID = "";

        int max = 0;

        string CustomSerial = "";

        private void Form1_Load(object sender, EventArgs e)

        {

            UserLocalName = System.Environment.MachineName.ToString();

            MD5CryptoServiceProvider Md5 = new MD5CryptoServiceProvider();

            UTF32Encoding UTF32 = new UTF32Encoding();

            string HashRun1 = BitConverter.ToString(Md5.ComputeHash(UTF32.GetBytes(UserLocalName)));

            foreach (char a in HashRun1)

            {

                foreach (char check in InvalidCharacters)

                {

                    if (Char.ToUpper(a) == check)

                    {

                        InvalidChar = true;

                    }

                }

                if (InvalidChar == false)

                {

                if (max < 2)

                {

                    NewID += Convert.ToInt32(i);

                }

                max++;

            }

            max = 0;

            label3.Text += (Convert.ToInt32(NewID)*33).ToString();

            string Serial = (Convert.ToInt32(NewID) * 33).ToString() + System.Environment.MachineName;

            string SerialHash = BitConverter.ToString(Md5.ComputeHash(UTF32.GetBytes(Serial)));

            SerialHash += HashRun1;

            foreach (char a in SerialHash)

            {

                    {

                        InvalidChar = true;

                    }

                }

                if (InvalidChar == false)

                {

                    CustomSerial += a;

                }

                InvalidChar = false;

            }

            int DashAdder = 0;

            foreach (char i in CustomSerial)

            {

                if (max < 24)

                {

                    textBox2.Text += i;

                    if (DashAdder == 2 && max < 23)

                    {

                        textBox2.Text += "-";

                        DashAdder = -1;

                    }

                }

                max++;

                DashAdder++;

            }

        }

    }

}

C+, c++, c#, vb.net?

C# obviously.
