Help Hiding Java Code

[Szakalaka]

Hello. I would like to hide parts of server .java files (like AuthLogin.java, L2PacketHandler.java) etc to prevent them from being read by devs. They are parts of my antibot, the server owner sends me few java files and i return them modified so they can work with protected client on user's computer. I've seen lameguard, they got only 1 .jar file. How to do such thing?

You should make a Jar(obfuscate it too), but you need to know that it still will be possible to see the code(just like i can see the code of lameguard).

 

To create new Jar ,you need to create new Ant Build file. Example: http://pastebin.com/KuWDU47B

You don't need a new ant to create a jar.

http://proguard.sourceforge.net/makes it for you, but you have to be aware than any bug report will be obfuscated too. But ProGuard can generate a des-obfuscator in order to read such report.

 

There's no other option than obfuscation, from my knowledge.

its a choise but, mutating a package which is not only self used might cause read problems.

You have to track down external method calls for sure, and it can be painful if there are a lot.

Well, is it possible to create own package and insert there modified files and somehow tell the compiler to use my files instead of the original ones from project?
