It will ask for parts of the password supplied in step 3. When the bootloader starts, the MOK manager EFI utility should automatically start. # mokutil -import /root/module-signing/MOK.der A simple password is good enough, as it is only for temporary use. This is a two step process where the key is first imported, and then later must be enrolled when the machine is booted the next time.

Use the MOK (“Machine Owner Key”) utility to import the public key so that it can be trusted by the system.

# openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=YOUR_NAME/" I chose to use the root account and the directory /root/module-signing/ to store all things related to signing kernel modules.
