PROGRAM:
NAME
cert-to-efi-sig-list - tool for converting openssl certificates to EFI signature lists
SYNOPSIS
cert-to-efi-sig-list [-g <guid>] <crt file> <efi sig list file>
DESCRIPTION
Take an input X509 certificate (in PEM format) and convert it to an EFI signature list
file containing only that single certificate
OPTIONS
-g <guid>
Use <guid> as the owner of the signature. If this is not supplied, an all zero guid
will be used
EXAMPLES
To take a standard X509 certificate in PEM format and produce an output EFI signature list
file, simply do
cert-to-efi-sig-list PK.crt PK.esl
Note that the format of EFI signature list files is such that they can simply be
concatenated to produce a file with multiple signatures:
cat PK1.esl PK2.esl > PK.esl
If your platform has a setup mode key manipulation ability, the keys will often only be
displayed by GUID, so using the -g option to give your keys recognisable GUIDs will be
useful if you plan to manage lots of keys.
