code.delx.au - refind/blob - keys/README.txt

   1 This directory contains known public keys for Linux distributions and from
   2 other parties that sign boot loaders and kernels that should be verifiable
   3 by shim. I'm providing these keys as a convenience to enable easy
   4 installation of keys should you replace your distribution's version of shim
   5 with another one and therefore require adding its public key as a machine
   6 owner key (MOK).
   7
   8 Files come with three extensions. A filename ending in .crt is a
   9 certificate file that can be used by sbverify to verify the authenticity of
  10 a key, as in:
  11
  12 $ sbverify --cert keys/refind.crt refind/refind_x64.efi
  13
  14 The .cer and .der filename extensions are equivalent, and are public key
  15 files similar to .crt files, but in a different form. The MokManager
  16 utility expects its input public keys in this form, so these are the files
  17 you would use to add a key to the MOK list maintained by MokManager and
  18 used by shim.

  20 The files in this directory are, in alphabetical order:
  21
  22 - altlinux.cer -- The public key for ALT Linux (http://www.altlinux.com).
  23   Taken from the alt-uefi-certs package
  24   (http://www.sisyphus.ru/br/srpm/Sisyphus/alt-uefi-certs/spec).
  25
  26 - canonical-uefi-ca.crt & canonical-uefi-ca.der -- Canonical's public key,
  27   matched to the one used to sign Ubuntu boot loaders and kernels.
  28
  29 - centos.crt & centos.cer -- Public keys used to sign CentOS binaries, taken
  30   from shim-signed-0.9-2.el7.src.rpm. Note that the binary's centos.crt file
  31   was actually in .cer format, and has been renamed appropriately. The
  32   centos.crt file included here is transformed from the original file by
  33   openssl. Tested booting CentOS 7.
  34
  35 - fedora-ca.cer & fedora-ca.crt -- Fedora's public key, matched to the one
  36   used used to sign Fedora's shim 0.8 binary.
  37
  38 - microsoft-kekca-public.der -- Microsoft's key exchange key (KEK), which
  39   is present on most UEFI systems with Secure Boot. The purpose of
  40   Microsoft's KEK is to enable Microsoft tools to update Secure Boot
  41   variables. There is no reason to add it to your MOK list.
  42
  43 - microsoft-pca-public.der -- A Microsoft public key, matched to the one
  44   used to sign Microsoft's own boot loader. You might include this key in
  45   your MOK list if you replace the keys that came with your computer with
  46   your own key but still want to boot Windows. There's no reason to add it
  47   to your MOK list if your computer came this key pre-installed and you did
  48   not replace the default keys.
  49
  50 - microsoft-uefica-public.der -- A Microsoft public key, matched to the one
  51   Microsoft uses to sign third-party applications and drivers. If you
  52   remove your default keys, adding this one to your MOK list will enable
  53   you to launch third-party boot loaders and other tools signed by
  54   Microsoft. There's no reason to add it to your MOK list if your computer
  55   came this key pre-installed and you did not replace the default keys.
  56
  57 - openSUSE-UEFI-CA-Certificate.cer, openSUSE-UEFI-CA-Certificate.crt,
  58   openSUSE-UEFI-CA-Certificate-4096.cer, &
  59   openSUSE-UEFI-CA-Certificate-4096.crt -- Public keys matched to the ones
  60   used to sign OpenSUSE; taken from openSUSE's shim 0.7.318.81ee56d
  61   package.
  62
  63 - refind.cer & refind.crt -- My own (Roderick W. Smith's) public key,
  64   matched to the one used to sign refind_x64.efi and the 64-bit rEFInd
  65   drivers.
  66
  67 - SLES-UEFI-CA-Certificate.cer & SLES-UEFI-CA-Certificate.crt -- The Public
  68   key for SUSE Linux Enterprise Server; taken from openSUSE's shim
  69   0.7.318.81ee56d package.

  71 The refind.cer and refind.crt files are my creations and are distributed
  72 under the terms of the BSD 2-clause license. The rest of the files are
  73 distributed on the assumption that doing so constitutes fair use. Certainly
  74 they're all easily obtained on the Internet from other sources.
