Not signed to work with secure boot

[Florian Giest]

Dear Debian NVIDIA Maintainers,

today I figured out how easy it is to configure debian with Secure Boot, 
right just activating
Secure Boot in UEFI BIOS :'D.

Since when is it that easy btw? A year ago I didn't understand how to 
get it running.

So now to my subject. I recognized failed boot.log entries and found out 
that the nvidia
driver modules aren't signed yet.

I just want to know why it is like that, I mean how is shimx64.efi 
signed? By you, Fedora or Microsoft?
And if it is signed by you, which relation does the modules have with shim?

Would be nice if you could tell me because I didn't find anything about 
that on the internet.

Best reguards,

Linux newbie Flo
