Question Is there anyway to restore the obfuscated decomplied scripts?

For example, this is a section of decompiled script that was obfuscated before,as the variable name was replaced by "a"/"b"/"c",is there any tool to restore to original ,or like 90% ?

PS: Just for research ,not for any illegal purpose

 

I'm sure there are some deofuscators out there. Though it can not "restore" what isn't there anymore. In your case here since the argument names of all those setters is still there, it would be possible to derive the original field names from the argument names and what they are assigned to. So "a" should probably be "statusBarColor", etc ...

 

Cracking obfuscation algorithms is not exactly part of the curriculum on this board, but here's an idea: why don't you just ask the original developer to hook you up with the original code? Who knows, maybe he obfuscated it for no reason and would be happy to give it to ta total stranger, if asked nicely.

 

ChatGPT is capable of deobfuscating code but with the limitation that it has to be code that has an actual purpose since the way it does it is to look at the context of the surrounding code to determine how to name and lay out the code.
