not being able to read something which is encrypted is not a driver problem. do u expect the driver to crack the encryption? or guess the key?

nvidia has always been crap like this. Look at amd and intel, they let u write proper drivers (even if its real difficult to do so). No encrypted blobs or voodoo needed.

the nvidia drivers u need to use a card on Linux are unintelligible binary blobs. thats sad as it is.
