Ah. The wonders of our good friend Google! :P

I do not mean google. :rolleyes: I want to use it in my own Java applications.

In wikipedia, there is short description.

I am doing a research on that topic, and want to know deeply.

Help me please.

Thanks. :rolleyes:

If you know what obfuscation is, then it is mostly pointless. People can still disassemble the obfuscated code and search for strings (if they know how it obfuscates, possibly do more) rebranding your application or adding malicious code. If it is a trade secret, then putting it in plain Java functions may not be a good idea in the first place but rather in some compiled application or API that hooks in with Java.

Why not research Java obfuscation programs online? Quite possibly no one here would be able to answer without researching the current trends, or technologies of Java programming and you may as well get a good start.

When you obfsuscate code, you basically make it harder for another programmer to understand what you have done (class names get changed). For example, if you were to look at Minecraft's code obfuscated, the class names would be a.class, aa.class, aab.class etc.

Thats sorta the best description I can come up with, I know people have already responded but I wanted to explain.

Yeah this is correct. If you would just take a java decompiler and decompile the minecraft jar file, you would just get a bunch of random letters and words which have nothing to do with anything in the code. It's just to hide the code from other programmers and make it harder for them to find. Someone managed to get around this and made the Minecraft Coder Pack (MCP) which is used to create minecraft mods.

Somebody looked at meaning, rather than letters. It takes time, but can be done.
