How to protect or secure java code from decompiling
提问by Rakesh
I got a small doubt here. While we are generating any new application we used to deliver them as jar files. Now my question is are we able to decompile these jar files...? if yes how can I avoid that...? Please let me know, thanks in advance.
我在这里有一个小疑问。当我们生成任何新应用程序时，我们曾经将它们作为 jar 文件交付。现在我的问题是我们是否能够反编译这些 jar 文件......？如果是，我该如何避免...？请让我知道，提前谢谢。

You can decompile jar files (have a look at jd-decompiler). You can't avoid it! You just make it harder to read it with an obfuscator. (have a look at SandMark)
你可以反编译 jar 文件（看看 jd-decompiler）。你无法避免！你只是用混淆器让它更难阅读。（看看沙马克）
or create a programm which loads a crypted version of yours at runtime into memory.
或创建一个程序，在运行时将您的加密版本加载到内存中。

Decompilation cannot be avoided. You can easily make the code hard to read. There are free libraries available to obfuscate the code. proguard.sourceforge.net
无法避免反编译。您可以轻松地使代码难以阅读。有免费的库可用于混淆代码。proguard.sourceforge.net
