Help/Support XXTEA Decryption Help

Leyra.vkc · March 27, 2025

Hello, i am trying to "hack" an ios mobile game. I have reversed the executable file in its *.ipa with Ghidra.

I don't know how to post the executable file in question, but i will leave a mediafire link.

Anyway, the files are encrypted with xxtea system, the signature is "AXXTEA" (present in the beginning of all the encrypted *.luac files) and i am just searching for the key do decrypt the files.

Actually, with Ghidra i have found (quite easily) the only part of the code where the "AXXTEA" string is mentionned (it is in the FUN_100025eac function).

With my very limited experience, i am here to seek help or advices. My goal is not only to get the key but also to learn how all of this works.

Thanks to you guys in advance.
