机器码生成

1. 生成 32 位机器码

using System.Management;
using System.Security.Cryptography;
using System.Text;

public string Get32BitMachineCode()
{
    string cpuInfo = string.Empty;
    string hddInfo = string.Empty;

    // 获取CPU序列号
    ManagementObjectSearcher cpuSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
    foreach (ManagementObject mo in cpuSearcher.Get())
    {
        cpuInfo = mo["ProcessorId"].ToString();
        break;
    }

    // 获取硬盘序列号
    ManagementObjectSearcher hddSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
    foreach (ManagementObject mo in hddSearcher.Get())
    {
        hddInfo = mo["SerialNumber"].ToString();
        break;
    }

    // 1. 拼接硬件信息
    string rawInfo = cpuInfo + hddInfo;

    // 2. 使用 MD5 生成 32 位哈希值
    using (MD5 md5 = MD5.Create())
    {
        byte[] inputBytes = Encoding.UTF8.GetBytes(rawInfo);
        byte[] hashBytes = md5.ComputeHash(inputBytes);

        // 3. 将字节数组转换为 32 位的十六进制字符串
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < hashBytes.Length; i++)
        {
            sb.Append(hashBytes[i].ToString("X2")); // X2 表示大写十六进制
        }
        return sb.ToString(); // 返回固定 32 位的字符串
    }
}

2. 生成 32 位注册码

public string Get32BitRegCode(string machineCode)
{
    // 开发者自定义的内部密钥，用于增加破解难度
    string secretKey = "My_Secret_Key_2024";

    // 将机器码和密钥拼接
    string rawString = machineCode + secretKey;

    using (MD5 md5 = MD5.Create())
    {
        byte[] inputBytes = Encoding.UTF8.GetBytes(rawString);
        byte[] hashBytes = md5.ComputeHash(inputBytes);

        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < hashBytes.Length; i++)
        {
            sb.Append(hashBytes[i].ToString("X2"));
        }
        return sb.ToString(); // 返回固定 32 位的注册码
    }
}

3. 调用

// 获取 32 位机器码
string mCode = Get32BitMachineCode();
Console.WriteLine("机器码: " + mCode); // 输出示例: 5D41402ABC4B2A76B9719D911017C592

// 生成 32 位注册码
string rCode = Get32BitRegCode(mCode);
Console.WriteLine("注册码: " + rCode); // 输出示例: 8B1A9953C4611296A827ABF8C47804D7
