混淆是一种方法,但它不能防止破坏应用程序的盗版保护安全性。如何确保应用程序不被篡改,如何确保注册机制不会被逆向工程?

此外,还可以将c#应用程序转换为本机代码,而Xenocode的成本太高。

c#提供了很多特性,是编写代码的理想语言,所以用c++重新编写整个代码库是不可能的。

安全证书可以很容易地从. net中的签名程序集中删除。

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。

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。

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.

Here's one idea: you could have a server hosted by your company that all instances of your software need to connect to. Simply having them connect and verify a registration key is not sufficient -- they'll just remove the check. In addition to the key check, you need to also have the server perform some vital task that the client can't perform itself, so it's impossible to remove. This of course would probably mean a lot of heavy processing on the part of your server, but it would make your software difficult to steal, and assuming you have a good key scheme (check ownership, etc), the keys will also be difficult to steal. This is probably more invasive than you want, since it will require your users to be connected to the internet to use your software.

还有Salamander,这是一个来自Remotesoft的原生。net编译器和链接器,可以在没有。net框架的情况下部署应用程序。我不知道它是否符合它所宣称的。

. net Reflector只能打开“托管代码”,这基本上意味着“。NET代码”。所以你不能用它来分解COM DLL文件、原生c++、经典的Visual Basic 6.0代码等。编译后的。net代码的结构非常方便、可移植、可发现、可验证等。net Reflector利用了这一点,让你窥探已编译的程序集,但反编译器和反汇编器绝不是。net特有的,它们和编译器一样早就存在了。

您可以使用混淆器使代码更难阅读,但是您不能在不使. net无法读取的情况下完全阻止它被反编译。市面上有一些产品(通常价格昂贵)声称可以将托管代码应用程序“链接”到本地代码应用程序,但即使这些产品真的可以工作,有决心的人总能找到方法。

然而,当涉及到混淆时,一分钱一分货。因此,如果您的代码是如此专有,以至于您必须竭尽全力来保护它,那么您应该愿意在一个好的混淆器上投资。

However, in my 15 or so years of experience writing code I've realized that being over-protective of your source code is a waste of time and has little benefit. Just trying to read original source code without supporting documentation, comments, etc. can be very difficult to understand. Add to that the senseless variable names that decompilers come up with and the spaghetti code that modern obfuscators create - you probably don't have to worry too much about people stealing your intellectual property.
