创建不可逆向工程的Java程序 [英] Creating non-reverse-engineerable Java programs

问题描述

有没有办法以不可逆向工程的格式部署Java程序？

Is there a way to deploy a Java program in a format that is not reverse-engineerable?

我知道如何将我的应用程序转换为可执行的JAR文件，但我想确保代码不能被反向工程，至少不容易。

I know how to convert my application into an executable JAR file, but I want to make sure that the code cannot be reverse engineered, or at least, not easily.

对源代码的模糊处理不计入...它使得更难理解代码，但不隐藏它。

Obfuscation of the source code doesn't count... it makes it harder to understand the code, but does not hide it.

相关问题是 如何锁定编译的Java类以防止反编译？

程序，我仍然可以访问原始源，所以维护应用程序不会是问题。如果应用程序是分布式的，我不想让任何用户能够反编译它。混淆没有实现这一点，因为用户仍然能够反编译它，并且虽然他们将难以跟随动作流程，他们将能够看到代码，并可能从中获取信息。

Once I've completed the program, I would still have access to the original source, so maintaining the application would not be the problem. If the application is distributed, I would not want any of the users to be able to decompile it. Obfuscation does not achieve this as the users would still be able to decompile it, and while they would have difficulty following the action flows, they would be able to see the code, and potentially take information out of it.

我关心的是如果有关远程访问的代码中有任何信息。应用程序使用用户提供的用户ID和密码连接到的主机。

What I'm concerned about is if there is any information in the code relating to remote access. There is a host to which the application connects using a user-id and password provided by the user. Is there a way to hide the host's address from the user, if that address is located inside the source code?

推荐答案

您可以使用这个方法来隐藏主机的地址，使用 YGuard 模糊您的JAR文件。 它不会模糊您的源代码，而是编译的类，因此稍后维护代码没有问题。

You could obfuscate your JAR file with YGuard. It doesn't obfuscate your source code, but the compiled classes, so there is no problem about maintaining the code later.

隐藏一些字符串，你可以加密它，使它更难通过查看源代码（如果你混淆JAR文件，它是更好的）。

If you want to hide some string, you could encrypt it, making it harder to get it through looking at the source code (it is even better if you obfuscate the JAR file).
