C#產生軟體註冊碼

開發軟體時，當用到商業用途時，註冊碼與啟用碼就顯得很重要了。現在的軟體破解技術實在在強了，各種國內外大型軟體都有註冊機制，但同時也不斷地被破解。下面發的只是一個常用版本，發出源碼被破就更容易了，但我們學習的是技術。當然也為以後自己的軟體不會被輕易破解。

 

第一步。根據卷標，CPU序號，產生機器碼

// 取得裝置硬碟的卷標號

        public static string GetDiskVolumeSerialNumber()

        {

            ManagementClass mc = new ManagementClass(“Win32_NetworkAdapterConfiguration”);

            ManagementObject disk = new ManagementObject(“win32_logicaldisk.deviceid=”d:”");

            disk.Get();

            return disk.GetPropertyValue(“VolumeSerialNumber”).ToString();

        }

 

        //獲得CPU的序號

        public static string getCpu()

        {

            string strCpu = null;

            ManagementClass myCpu = new ManagementClass(“win32_Processor”);

            ManagementObjectCollection myCpuConnection = myCpu.GetInstances();

            foreach (ManagementObject myObject in myCpuConnection)

            {

                strCpu = myObject.Properties["Processorid"].Value.ToString();

                break;

            }

            return strCpu;

        }

        //產生機器碼

        public static string getMNum()

        {

            string strNum = getCpu() + GetDiskVolumeSerialNumber();//獲得24位Cpu和硬碟序號

            string strMNum = strNum.Substring(0, 24);//從產生的字串中取出前24個字元做為機器碼

            return strMNum;

        }

        public static int[] intCode = new int[127];//儲存體金鑰

        public static int[] intNumber = new int[25];//存機器碼的Ascii值

        public static char[] Charcode = new char[25];//儲存機器碼字

        public static void setIntCode()//給數組賦值小於10的數

        {

            for (int i = 1; i < intCode.Length; i++)

            {

                intCode[i] = i % 9;

            }

        }

 

第二步。根據機器碼 產生註冊碼

        //產生註冊碼    

 

       public static string getRNum()

        {

            setIntCode();//初始化127位元組

            for (int i = 1; i < Charcode.Length; i++)//把機器碼存入數組中

            {

                Charcode[i] = Convert.ToChar(getMNum().Substring(i – 1, 1));

            }

            for (int j = 1; j < intNumber.Length; j++)//把字元的ASCII值存入一個整數組中。

            {

                intNumber[j] = intCode[Convert.ToInt32(Charcode[j])] + Convert.ToInt32(Charcode[j]);

            }

            string strAsciiName = “”;//用於儲存註冊碼

            for (int j = 1; j < intNumber.Length; j++)

            {

                if (intNumber[j] >= 48 && intNumber[j] <= 57)//判斷字元ASCII值是否0－9之間

                {

                    strAsciiName += Convert.ToChar(intNumber[j]).ToString();

                }

                else if (intNumber[j] >= 65 && intNumber[j] <= 90)//判斷字元ASCII值是否A－Z之間

                {

                    strAsciiName += Convert.ToChar(intNumber[j]).ToString();

                }

                else if (intNumber[j] >= 97 && intNumber[j] <= 122)//判斷字元ASCII值是否a－z之間

                {

                    strAsciiName += Convert.ToChar(intNumber[j]).ToString();

                }

                else//判斷字元ASCII值不在以上範圍內

                {

                    if (intNumber[j] > 122)//判斷字元ASCII值是否大於z

                    {

                        strAsciiName += Convert.ToChar(intNumber[j] – 10).ToString();

                    }

                    else

                    {

                        strAsciiName += Convert.ToChar(intNumber[j] – 9).ToString();

                    }

                }

            }

            return strAsciiName;

        }

 

第三步。檢查註冊狀況，若沒有註冊，可自訂試用     

 

/// <summary>

        /// 檢查註冊

        /// </summary>

        private void CheckRegist()

        {

 

                this.btn_reg.Enabled = true;

 

                  RegistryKey retkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(“software”, true).CreateSubKey(“wxk”).CreateSubKey(“wxk.INI”);

                foreach (string strRNum in retkey.GetSubKeyNames())//判斷是否註冊

                {

                    if (strRNum == clsTools.getRNum())

                    {

                        thControl(true);

                        return;

                    }

                }

                thControl(false);

                Thread th2 = new Thread(new ThreadStart(thCheckRegist2));

                th2.Start();

 

          }

        }

    

        /// <summary>

        /// 驗證試用次數

        /// </summary>

        private static void thCheckRegist2()

        {

            MessageBox.Show(“您現在使用的是試用版，該軟體可以免費試用3000000次！”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);

            Int32 tLong;

            try

            {

                tLong = (Int32)Registry.GetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, 0);

                MessageBox.Show(“感謝您已使用了” + tLong + “次”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

            catch

            {

                Registry.SetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, 0, RegistryValueKind.DWord);

                MessageBox.Show(“歡迎新使用者使用本軟體”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

            tLong = (Int32)Registry.GetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, 0);

            if (tLong < 3000000)

            {

                int Times = tLong + 1;

                Registry.SetValue(“HKEY_LOCAL_MACHINE\SOFTWARE\angel”, “UseTimes”, Times);

            }

            else

            {

                MessageBox.Show(“試用次數已到”, “警告”, MessageBoxButtons.OK, MessageBoxIcon.Warning);

                Application.Exit();

            }

        }
