开发软件时,当用到商业用途时,注册码与激活码就显得很重要了。现在的软件破解技术实在在强了,各种国内外大型软件都有注册机制,但同时也不断地被破解。下面发的只是一个常用版本,发出源码被破就更容易了,但我们学习的是技术。当然也为以后自己的软件不会被轻易破解。

 

第一步。根据卷标,CPU序列号,生成机器码

// 取得设备硬盘的卷标号

        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();

        }

 

        //获得CPU的序列号

        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;

        }

        //生成机器码

        public static string getMNum()

        {

            string strNum = getCpu() + GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号

            string strMNum = strNum.Substring(0, 24);//从生成的字符串中取出前24个字符做为机器码

            return strMNum;

        }

        public static int[] intCode = new int[127];//存储密钥

        public static int[] intNumber = new int[25];//存机器码的Ascii值

        public static char[] Charcode = new char[25];//存储机器码字

        public static void setIntCode()//给数组赋值小于10的数

        {

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

            {

                intCode[i] = i % 9;

            }

        }

 

第二步。根据机器码 生成注册码

        //生成注册码    

 

       public static string getRNum()

        {

            setIntCode();//初始化127位数组

            for (int i = 1; i < Charcode.Length; i++)//把机器码存入数组中

            {

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

            }

            for (int j = 1; j < intNumber.Length; j++)//把字符的ASCII值存入一个整数组中。

            {

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

            }

            string strAsciiName = “”;//用于存储注册码

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

            {

                if (intNumber[j] >= 48 && intNumber[j] <= 57)//判断字符ASCII值是否0-9之间

                {

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

                }

                else if (intNumber[j] >= 65 && intNumber[j] <= 90)//判断字符ASCII值是否A-Z之间

                {

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

                }

                else if (intNumber[j] >= 97 && intNumber[j] <= 122)//判断字符ASCII值是否a-z之间

                {

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

                }

                else//判断字符ASCII值不在以上范围内

                {

                    if (intNumber[j] > 122)//判断字符ASCII值是否大于z

                    {

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

                    }

                    else

                    {

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

                    }

                }

            }

            return strAsciiName;

        }

 

第三步。检查注册状况,若没有注册,可自定义试用     

 

/// <summary>

        /// 检查注册

        /// </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())//判断是否注册

                {

                    if (strRNum == clsTools.getRNum())

                    {

                        thControl(true);

                        return;

                    }

                }

                thControl(false);

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

                th2.Start();

 

          }

        }

    

        /// <summary>

        /// 验证试用次数

        /// </summary>

        private static void thCheckRegist2()

        {

            MessageBox.Show(“您现在使用的是试用版,该软件可以免费试用3000000次!”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);

            Int32 tLong;

            try

            {

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

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

            }

            catch

            {

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

                MessageBox.Show(“欢迎新用户使用本软件”, “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(“试用次数已到”, “警告”, MessageBoxButtons.OK, MessageBoxIcon.Warning);

                Application.Exit();

            }

        }
