软件注册码生成
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(); |
} |
} |
