Decrypt lua files of Cocos2dx ?

[hackspeedok]

Hi everybody,
I want to translate a Chinese IOS game to my language. But I dont know how to decrypt Lua files of Cocos2dx (I'm noob). I read this article but still do not understand: https://boards.libre.io/threads/decrypt ... es.297552/
So, I hope someone is able to help me decrypt these files, I am extremely thankful

Thanks Aluigi, can you help me to encrypt the edited files ? I tried reimport but the new files must be same size as original

Script 0.2, you must re-decrypt the files because it now adds a "_decrypt" suffix in the filename.
Reuse the script on the decryted files to automatically encrypt them

Unfortunately I can't, I can only write a script once someone will post the algorithm and key.

I found out xxtea by simple, unfortunately my ability is not enough to find the key, the game uses anti-debugging.

Code: Select all

int __fastcall cocos2d::xxtea_decrypt(int a1, int a2, int a3, unsigned int a4, int a5, int a6, int a7, int a8, int (__fastcall *a9)(int), int a10, int a11, int a12, _DWORD *a13)
{
  unsigned int v13; // r7
  int v14; // r6
  int v15; // r4
  int v17; // [sp+24h] [bp+4h]
  int v18; // [sp+28h] [bp+8h]

  v13 = a4;
  *a13 = 0;
  if ( a4 > 0xF )
  {
    v15 = sub_73D7FC(a1, a2, a3, a13);
  }
  else
  {
    v18 = a2;
    v17 = a1;
    v14 = sub_6C65B4(16);
    sub_6C63F4();
    sub_6C64B4(v14 + v13, 16 - v13, 0);
    v15 = sub_73D7FC(v17, v18, v14, a13);
    sub_6C64C4(v14);
  }
  return a9(v15);
}
