  • How do I know if my Linux kernel is signed?

    I registered my own machine principal (MOK) and signed some of the most important kernel modules. It seems to work right away, but it should work: I just typed modinfo -in nvidia, then used tab completion to successfully show kernel modules with names starting with “nvidia”. But how do I know that I went deep and did not miss anything?

    What Is A “signed” Kernel Module?

    An electronic signature is an operation aimed at verifying the identitydigital advice. To do this, you can use an existing digital private bank.the “signed” content was created by a known sender, and this datahas not changed between the time the signature was created and the current state.
