EULA violation: Decrypting .kn5 files for asset extraction violates Kunos Simulazioni's EULA (Section 4: reverse engineering, decompilation, or derivative works).
Modding allowed only via official SDK: Kunos permits modding only through KSEditor + FBX export from 3D software — not via decryption of encrypted game assets.
Legal precedent: DMCA 1201 applies to circumvention of effective access controls (XOR counts as trivial obfuscation, but some jurisdictions still treat it as protection).

Not full decryption: This only removes the XOR layer, exposing the internal KN5 container structure. The resulting data still uses Kunos’s binary serialization format (not standard FBX/OBJ).
Textures: Stored as DDS in separate .dds files or embedded — decryption alone won't yield editable textures.
No encryption in latest versions: Some post-2019 titles use AES-128? False — verified: same XOR across all Kunos titles up to Assetto Corsa Competizione (ACC uses a different, stronger packing).
