当涉及到。net时，如果你正在发布Windows窗体应用程序(或任何客户端有可移植可执行文件的应用程序)，它就有可能被破解。

如果你想坚持使用。net，并且想把你的源代码被窃取的几率降到最低，那么你可以考虑将它部署为ASP。NET应用程序，而不是使它成为一个Windows窗体应用程序。

使用Skater . net混淆器。该. net保护工具针对de4dot, de4dot是一个去混淆器，它将原始受保护的程序集成员名称重命名为人类可读的字符串。溜冰者与之对抗!

最近，MindSystemm集团发布了一个名为Skater的特殊工具。NetDeobfuscator [url: https://github.com/MindSystemm/Skater.NetDeobfuscator]，它利用了Skater. net混淆器的漏洞。 混淆器的开发者Rustemsoft LLC收到了一个迫切需要保护关键的Skater . net混淆器算法和软件基础设施的信号，以便为Skater用户提供更强的源代码保护。这个问题已经解决了。

Jared指出de4dot声称能够反编译它。

.NET Reactor provides complete protection for your sensitive intellectual property by converting your .NET assemblies into unmanaged processes which cannot be understood as CIL, and which no existing tool can decompile. Hackers have no access to any intelligible form of your source. Powerful and flexible, the .NET Reactor licensing features allow you to enforce your license conditions and protect your revenue stream by using hardware and software locks. The license manager can build trial or permanent licenses, in a matter of seconds. A fully documented software development kit (SDK), complete with examples, allows you to call the licensing system directly from your code, allowing you to create custom extensions to the licensing system.

你无法阻止别人破解你的软件。

However, you can make them create cracks that will hurt your sales less. Keygenerators that can issue a valid registration code for your software are much worse than simple patches that remove registration incentives from your software. That's because a crack will work for one software version only, and will cease to work with the next software update you release. The keygenerator will continue to work until you change your registration key algorithm and that's something you don't want to do often because it will put off your honest clients.

因此，如果您正在寻找一种方法来对抗非法的密钥生成器，并且您不想使用不对称加密，因为这会生成很长的注册码，您可以看看部分密钥验证。

Partial Key Verification makes sure that each illegal keygenerator works only for one particular release of your software. Basically what you do is to make sure that each release of your software only links with the code for checking SOME digits of the registration code. Which digits exactly is random, so crackers would have to reverse engineer many different versions of your software and combine all this into one keygenerator in order to release a keygenerator that works for all versions of your software.

如果你定期发布新的软件版本，这将导致大量的密钥生成器散布在各种软件盗版档案中，这些文件不再工作。潜在的软件盗版者通常会寻找最新版本的破解或关键元素，所以他们可能会尝试其中的一些，并最终放弃。

我在我的(c++)新共享游戏中使用了部分密钥验证，它非常有效。之前我们遇到了很多无法对抗的关键生成器问题。后来出现了许多漏洞，一些按键生成器只适用于特定版本的游戏，但没有一个按键生成器适用于所有版本。我们定期发布游戏的小更新，让之前存在的所有漏洞都变得无用。

似乎有一个用于部分密钥验证的开源。net框架，尽管我还没有尝试过。

是的，. net二进制文件(EXE和DLL)可以很容易地反编译成接近源代码。检查. net Reflector工具。在任何。net二进制文件上尝试一下。最好的选择是混淆文件，它们仍然可以被。net Reflector反编译，但它们会造成一团不可读的混乱。我不认为好的混淆器是免费或廉价的。一个是Visual Studio附带的Dotfuscator社区版。
