Unable to find Key [UE 4.14]

[Marold57]

Hey :D

I try for longer time to find the Encryption Key for my Game "Space Hulk Deathwing: Enhanced Edition" [Unreal Engine 4.14].
Its worth noting, the PAK is NOT Encrypt! :) The Game have three encrypt ini Files inside the PAK in the Config Folder.
I want to decrypt this Config files. But i was unable to find the Decryption Key.

Some (maybe important) information:

1. All encrypt ini Files share the same first bytes.
2. The Game decrypts the Files for me when i Copy the encrypt ini Files from the PAK to
   C:\Users\Username\AppData\Local\SpaceHulkEnhanced\Saved\Config\WindowsNoEditor
   Problem is, i cant use the ini Files when i cant encryp them back with the right Key.
3. Game decrypts the encrypt Files not at the same time. First File is before the Splash Screen appears, when start the Game. Second is when load a Map/Level. The last is when spawn in the Map/Level begin.

Thanks for any help
