Help/Support Il2cpp Dumper can not decrypt the function name of an Unity app

hungvi0610 · December 31, 2022

I tried to decrypt an app using iGDecrypt, then use Il2cpp Dumper online to get the source code but the problem is not all the function's names are decrypted. There are still a lot of functions I can't read clearly as you can see in the screenshot. How can I solve this issue to read the code?

Hi @hungvi0610,

It seems that the developers of the application has set the function names in characters other than the English alphabet. Hence, you will need to use Google Translator to translate the function names to something you can understand.

They probably used beebyte to obfuscate the method names. You could decrypt an older version of the game and see if the names are obfuscated there too, if not you could compare the older with newer dump manually or use a plugin that deobfuscates them.
