UEFISIGN(8)             FreeBSD System Manager's Manual            UEFISIGN(8)

NAME

     uefisign - UEFI Secure Boot signing utility

SYNOPSIS

     uefisign -k key -c certificate -o output [-v] file
     uefisign -V [-v] file

DESCRIPTION

     The uefisign utility signs PE binary files using Authenticode scheme, as
     required by UEFI Secure Boot specification.  Alternatively, it can be
     used to view and verify existing signatures.  These options are
     available:

     -V      Determine whether the file is signed.  Note that this does not
             verify the correctness of the signature; only that the file
             contains a signature.

     -k      Name of file containing the private key used to sign the binary.

     -c      Name of file containing the certificate used to sign the binary.

     -o      Name of file to write the signed binary to.

     -v      Be verbose.

EXIT STATUS

     The uefisign utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     Generate self-signed certificate and use it to sign a binary:
           /usr/share/examples/uefisign/uefikeys testcert
           uefisign -c testcert.pem -k testcert.key -o signed-binary binary

     View signature:
           uefisign -Vv binary
