c# - Sentinel Hl Basic 保护供应商代码

Question

我使用波纹管代码来保护一段 .net 程序。我们选择使用 api 而不是经典的 Envelope 方法，因为我们想要自定义行为而不仅仅是普通窗口“找不到 key ”

我的问题是如何保护供应商代码，因为它可以在反编译器中被视为纯文本？

提前致谢。

    HaspFeature feature = HaspFeature.Default;

// Key bellow is random generated.....
    string vendorCode = 
    "AzIceaqfA1hX5wS+M8cGnYh5ceevUnOZIzJBbXFD6dgf3tBkb9cvUF/Tkd/iKu2fsg9wAysYKw7RMAsV" +

    Hasp hasp = new Hasp(feature);
    HaspStatus status = hasp.Login(vendorCode);

    if (HaspStatus.StatusOk != status)
    {
        //handle error
        Application.Exit();
    }

使用 ConfuserEx 的工作示例混淆程序集。

// sentinel demo key...      
private static string CodeDemo_Internal()
    {
        return "AzIceaqfA1hX5wS+M8cGnYh5ceevUnOZIzJBbXFD6dgf3tBkb9cvUF/Tkd/iKu2fsg9wAysYKw7RMAsV" +

    }

混淆输出...

private static string CodeDemo_Internal()
    {
      string str = \u003CModule\u003E.\u206F‏‎‬‌‮‫‭​‎‎‫‭‮‮‏‫‪‏‫‮<string>(2388152962U);
label_1:
      int num1 = 2017564117;
      while (true)
      {
        uint num2;
        switch ((num2 = (uint) (num1 ^ 1541322575)) % 3U)
        {
          case 1:
            num1 = (int) num2 * 795888831 ^ 1645877581;
            continue;
          case 2:
            goto label_1;
          default:
            goto label_4;
        }
      }
label_4:
      return str;
    }

这是在...上进行了以下设置
