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.
