C# 產生軟體註冊碼
今天早上,花了一個早上弄了個產生機器碼和註冊碼的Demo,通過產生的註冊碼裡麵包含時間資訊,保證了註冊碼在使用後的指定時間後失效
由於數學不行所以寫的比較簡單,ok 上代碼吧 產生機器碼的原理很簡單,基本上都是取裝置資訊之後加密
/// <summary> /// 取本機機器碼 /// </summary> public static string GetMachineCode() { //CPU資訊 string cpuId = DeviceHelper.GetCpuID(); //磁碟資訊 string diskId = DeviceHelper.GetDiskID(); //網卡資訊 string MacAddress = DeviceHelper.GetMacAddress(); string m1 = GetMD5(cpuId + typeof(string).ToString()); string m2 = GetMD5(diskId + typeof(int).ToString()); string m3 = GetMD5(MacAddress+typeof(double).ToString()); string code1 = GetNum(m1, 8); string code2 = GetNum(m2, 8); string code3 = GetNum(m3, 8); return code1 + code2 + code3; }
產生註冊碼
/// <summary> /// 根據機器碼產生註冊碼 /// </summary> /// <param name="machineCode">機器碼</param> /// <param name="overTime">到期時間</param> /// <returns></returns> public static string CreateRegisterCode(string machineCode,DateTime overTime) { int year = int.Parse(overTime.Year.ToString().Substring(2))+33; int month = overTime.Month+21; int day = overTime.Day+54; int section = machineCode.Length / 4; string reg = ""; int n = 1597; for (int i = 0; i < section; i++) { int sec = int.Parse(machineCode.Substring(i*4,4)); int resu = sec + n; if (resu >= 10000) { resu = sec - 1597; } reg += resu ; n = n + 1597; } //插入年月日資訊 reg = InsertNum(reg, year, 0, 8, 4, 6, 7, 1, 3, 2, 5, 9); reg = InsertNum(reg, month, 0, 6, 9, 7, 3, 8, 4, 1, 2, 5); reg = InsertNum(reg, day, 0,1, 2, 5, 6,7, 3, 8, 9, 4); return reg.ToString(); } /// <summary> /// 在指定數字後面插入內容 /// </summary> /// <param name="str"></param> /// <param name="num"></param> /// <param name="index"></param> /// <param name="pmc"></param> /// <returns></returns> static string InsertNum(string str,int num,int index,params int[] pmc) { int posi = str.IndexOf(pmc[index].ToString()); if (posi <= -1) return InsertNum(str, num, index + 1, pmc); return str.Insert(posi, num.ToString()); }
驗證註冊碼
/// <summary> /// 檢查註冊碼 /// </summary> /// <param name="registerCode"></param> /// <param name="overTime"></param> /// <returns></returns> public static bool CheckRegister( string registerCode,ref DateTime overTime) { try { string machineCode = GetMachineCode(); //提取年月日 int day = int.Parse(ExtractNum(ref registerCode, 0, 1, 2, 5, 6, 7, 3, 8, 9, 4)); int month = int.Parse(ExtractNum(ref registerCode, 0, 6, 9, 7, 3, 8, 4, 1, 2, 5)); int year = int.Parse(ExtractNum(ref registerCode, 0, 8, 4, 6, 7, 1, 3, 2, 5, 9)); day -= 54; month -= 21; year -= 33; overTime = new DateTime(year, month, day); //核對註冊碼 int section = machineCode.Length / 4; int n = 1597; string reg = ""; for (int i = 0; i < section; i++) { int sec = int.Parse(machineCode.Substring(i * 4, 4)); int resu = sec + n; if (resu >= 10000) { resu = sec - 1597; } reg += resu; n = n + 1597; } return registerCode == reg; } catch { return false; } } /// <summary> /// 提取數字 /// </summary> /// <param name="str"></param> /// <param name="index"></param> /// <param name="pmc"></param> /// <returns></returns> static string ExtractNum(ref string str, int index, params int[] pmc) { int posi = str.IndexOf(pmc[index].ToString()); if (posi <= -1) return ExtractNum(ref str, index + 1, pmc); string resu = str.Substring(posi - 2, 2); str = str.Remove(posi - 2, 2); return resu; }
調用執行個體
//取機器碼 string mCode = RegInfo.GetMachineCode(); //產生註冊碼 string regCode = RegInfo.CreateRegisterCode(mCode, DateTime.Now); DateTime time = DateTime.Now; //驗證註冊碼 bool resu = RegInfo.CheckRegister(regCode+"1", ref time);
