This repo is for review of requests for signing shim. To create a request for review:

  • clone this repo
  • edit the template below
  • add the shim.efi to be signed
  • add build logs
  • commit all of that
  • tag it with a tag of the form “myorg-shim-arch-YYYYMMDD”
  • push that to github
  • file an issue at with a link to your tag

Note that we really only have experience with using grub2 on Linux, so asking us to endorse anything else for signing is going to require some convincing on your part.

Here's the template:

What organization or people are asking to have this signed:

Neverware Inc. (

What product or service is this for:


What's the justification that this really does need to be signed for the whole world to be able to boot it:

CloudReady is a Linux distro; we'd like to encourage people to boot our OS with secure boot enabled.

Who is the primary contact for security updates, etc.

Who is the secondary contact for security updates, etc.

What upstream shim tag is this starting from:

URL for a repo that contains the exact code which was built to get this binary:

What patches are being applied and why:


What OS and toolchain must we use to reproduce this build? Include where to find it, etc. We‘re going to try to reproduce your build as close as possible to verify that it’s really a build of the source tree you tell us it is, so these need to be fairly thorough. At the very least include the specific versions of gcc, binutils, and gnu-efi which were used, and where to find those binaries.

This repo contains the Dockerfile we use to build shim:

Which files in this repo are the logs for your build? This should include logs for creating the buildroots, applying patches, doing the build, creating the archives, etc.


Add any additional information you think we may need to validate this shim

This shim build is unchanged from our last submission and only updates the embedded EV code signing certificate.
