Default How to Revers this?

Hello,
i found this forum and i think people can help me.

So there is the game called s4League and they have an file called
resource.s4hd

i know that it is encrypted with an 40byte key and AES 256

The Main part is that the game has an folder called "_resources"
it contains all resource files.

the resrouce.s4hd contains an List from every file of the _resources folder. Both are encrypted with the same key.

But the Problem is, i dont know how to get the Key.

Can someone give me tipps or tricks?

would be really nice.
If this is the wrong section please move it.


if forgot its compressed with LZO [Limpel Zev Oberhumer]
Regards

Uhwerk

Yes, but im pretty new to reverse engineering.

So i found out that this key works for an other Version of the resource.s4hd
Code:
130, 0x53, 0x43, 0x4c, 0x2b, 0x0d, 0x37, 0xd7, 0xd9, 0xd8, 0x1b, 0x6d, 0xA0, 0xc3, 0x2b, 0xee, 
            0x45, 0x88, 0x1a, 0xa6, 0x18, 0x1d, 0x9d, 0x38, 0x2a, 0x55, 0x03, 0x1d, 0xcd, 0xa6, 0x73, 0x07, 
            0x72, 0x62, 0x72, 0x2b, 0x62, 0x77, 0x62, 0xd5
