Was contacted on Discord regarding this games .PAK files. Uses CryEngine so the main/default PAK usage is with an RSA key.

CryEngine is now open source which can be found on GitHub here:
https://github.com/CRYTEK/CRYENGINE

The RSA key is loaded inside of CrySystem now which is done here:
https://github.com/CRYTEK/CRYENGINE/blo ... .cpp#L1800

The key is still stored inside of CryGameSDK (Renamed from GameSDK/GameDLL when compiled for shipping) though here:
https://github.com/CRYTEK/CRYENGINE/blo ... p.cpp#L413

This games key is:
