复制.NET应用程序的保护 [英] Copy protection for a .NET application
问题描述
我打算使用C＃开发一个.NET应用程序，以便将它作为一个完整的软件包和/或一个完整的软件包出售，所以我需要一个很好的方法来保护它
打击盗版。我知道一些保护它的方法（激活，序列密钥，
等），但我担心的是：当你可以随时拆解时，任何复制保护机制如何工作？
它并阅读源代码？即使我使用
本机C ++ DLL进行复制保护，也可以随时找到从
C＃代码中调用它的位置。
这方面有什么好的建议吗？
谢谢

I''m planning to develop a .NET application using C#, in order to sell it as
a shareware and/or as a full package, so I''ll need a good way to protect it
against piracy. I know some ways to protect it (activation, serial keys,
etc.), but my concern is: how can any copy protection mechanism work when
you can always disassemble it and read the source code? Even if I use a
native C++ DLL for my copy protection, the point where it''s called from the
C# code can always be found.
Any good tips about this?
Thanks

推荐答案
使用好的混淆器。它至少会令人难以忍受。
我已经使用了一个来自smartowl并且看起来工作得很好。

Use a good obfuscator. It will atleast make it tough to disassenble.
I have benn using one from wiseowl and it seems to work pretty good.

是的 - 别担心。如果你特别想要混淆你的代码，但是
除非你确实*
确定：
a）对海盗版本有很多需求
b）技术上有能力的人愿意花费
时间反编译您的混淆代码

Yes - don''t worry. Obfuscate your code if you particularly want to, but
I wouldn''t bother going any further than that unless you''re *really*
sure that:
a) There''ll be lots of demand for pirate copies
b) There''ll be technically competent people who are willing to spend
time decompiling your obfuscated code

您可以检查混淆。但是根据混淆器的不同，那可能不会给你带来太大的收益。通过混淆代码可以很简单：

真正的方法是使用一个工具做的不仅仅是简单的命名
混淆（比如，输入混淆，调用混淆），加密你的
程序集，然后，编写真正混乱的代码关键部分。对于
实例，您可以尝试一些技巧来伪造您的堆栈跟踪，在串行检查中使用多个
线程等。部分。
还记得，如果有需求，人们会通过并破解你的
应用程序。甚至MS Window的激活也被破解了（Windows
程序员非常聪明）。

You can check into obfuscating. But depending on the obfuscator, that might
not buy you much. Getting thru obfuscated code can be simple:
http://www.atrevido.net/blog/PermaLi...b-fcc15eb297c3
The real way is to use a tool that does a lot more than just simple naming
obfuscation (say, type obfuscation as well, call obfuscation), encrypts your
assembly, and then, write really messed up code for the critical part. For
instance, you might try some tricks to fake your stack trace, use multiple
threads, etc. in the "serial checking" part.
Also remember, if there''s demand, people will get through and crack your
app. Even MS Window''s activation has been cracked (and the Windows
programmers are extremely intelligent).
