如果微软能想出一个解决方案，我们就不会有盗版的Windows版本，所以没有什么是非常安全的。下面是来自Stack Overflow的一些类似问题，您可以实现自己的保护方式。如果你正在发布不同的版本，那么你可以针对不同的版本采用不同的技术，这样当第一个版本被破解时，第二个版本就可以接管。

基于许可证管理c++应用程序的特性 使用license文件保护DLL文件 授权/保护软件?

广义上讲，有三种人。

Those who will not buy your software and resort to cracks, or if they don't find any, not use your software at all. Don't expect to make any money from this group. They rely either on their own skills or on crackers (who tend to prioritize their time depending on your useful and how big your audience is. The more useful, the sooner a crack will be available). The group of legitimate users who will buy (pay for) your software, irrespective of what protection mechanism you use. Don't make life hard for your legitimate users by using an elaborate protection mechanism since they are going to pay for it in any case. A complex protection mechanism can easily spoil the user experience and you don't want this happening to this group. Personally, I'd vote against any hardware solution, which adds to the cost of your software. A minority who will resort to "unethical" cracking and will only pay for your software because its features are protected by a licensing mechanism. You probably don't want to make it exceedingly easy for this group to circumvent your protection. However, all that effort you spend on protecting your software will pay back, depending on how big this group of people is. This entirely depends on the type of software you're building.

根据您所说的，如果您认为有足够多的少数人可以被推动购买您的软件，那么请继续执行某种形式的保护。考虑一下你能从这些少数人身上赚到多少钱，与你花在保护上的时间相比，或者你花在第三方保护API/工具上的钱。

如果您想实现自己的解决方案，那么使用公钥加密是防止容易被黑客攻击的好方法(与对称算法相反)。例如，您可以对您的许可证(序列号或许可证文件)进行数字签名。解决这个问题的唯一方法就是反编译、修改和重新编译代码(你可以使用Simucal回答中建议的技术来增加难度)。

客户端上运行的任何东西都可以被反编译和破解。混淆只会让它更难。我不了解你的应用程序，但99%的情况下，我认为不值得这么做。

看起来永远是本地的，现在不需要在混淆器; 看起来像网芯RT可行的解决方案;很快所有的应用程序都将使用。net core;https://www.codeproject.com/Articles/5262251/Generate-Native-Executable-from-NET-Core-3-1-Proje?msg=5753507 xx5753507xx https://learn.microsoft.com/en-us/archive/msdn-magazine/2018/november/net-core-publishing-options-with-net-core

没有测试过，也许用旧的win .net SDK可能做类似的事情。

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。

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。
