Afaik kernel modules are signed using:
Code:
certs/signing_key.pem
certs/signing_key.x509
Which one of the two should be deleted once installation is achieved?

Cap'n, thanks, I was investigating that very question not 10 minutes ago. Not sure how I missed that article.

Code:
signing_key.priv (-kernel 4.3.3)
certs/signing_key.pem (=+kernel 4.3.3)
consequently seems the element to be secured.
It's deleted here when rebuilding an existing kernel.[Edit: something went wrong here, don't do it].
Code:
signing_key.x509 (-kernel 4.3.3)
certs/signing_key.x509 (=+kernel 4.3.3)
remains unchanged.

May be doing wrong...
Plz speak out your mind.

Thks 4 ur attention, interest & support.
