NAME

   pesign - command line tool for signing UEFI applications

SYNOPSIS

   pesign [--in=infile | -i infile]
          [--out=outfile | -o outfile]
          [--certdir=certdir/fR | -n certdir]
          [--nss-token=token | -t token]
          [--certificate=nickname | -c nickname]
          [--force | -f] [--sign | -s] [--hash | -h]
          [--digest_type=digest | -d digest]
          [--show-signature | -S ] [--remove-signature | -r ]
          [--export-pubkey=outkey | -K outkey]
          [--export-cert=outcert | -C outcert]
          [--ascii-armor | -a] [--daemonize | -D] [--nofork | -N]
          [--signature-number=signum | -u signum]

DESCRIPTION

   pesign   is  a  command  line  tool  for  manipulating  signatures  and
   cryptographic digests of UEFI applications.

OPTIONS

   --in=infile
          Specify input binary.

   --out=outfile
          Specify output binary.

   --certdir=certdir
          Specify nss certificate database directory.

   --nss-token=token
          Use the specified NSS token's certificate database.

   --certificate=nickname
          Use the certificate database entry with the  specified  nickname
          for signing.

   --force
          Overwrite  output  files.  Without  this  parameter, pesign will
          refuse to overrite any output files which already exist.

   --sign Sign the input binary with the key specified by --certificate.

   --hash Display the cryptographic digest of the input binary on standard
          output.

   --digest_type=digest
          Use  the  specified digest in hashing and signing operations. By
          default, this value is "sha256".   Use  "--digest_type=help"  to
          list the available digests.

   --show-signature
          Show information about the signature of the input binary.

   --remove-signature
          Remove the signature section from the binary.

   --signature-number=signum
          Specify  which  signature  to  operate  on.  This field is zero-
          indexed.

   --export-pubkey=outkey
          Export the public key specified by --certificate to outkey

   --export-cert=outcert
          Export the certificate specified by --certificate to outcert

   --ascii
          Use ascii armoring on exported certificates.

   --daemonize
          Spawn a daemon for use with pesign-client(1)

   --nofork
          Do not fork when using --daemonize.

EXAMPLES

   If you have a certificate file and  private  key  file,  the  following
   steps may be used to sign a PE image:

       # Create a pkcs12 file from private key and
       # certificate file.
       host:~$ openssl pkcs12 -export -out foo_key.p12 \
                       -inkey signing_key.pem \
                       -in xyz_cert.x509.pem

       # Import pkcs12 file into pesign db
       host:~$ pk12util -i foo_key.p12 -d /etc/pki/pesign

       # Do the signing
       host:~$ pesign -i <input-file> -o <output-file> \
                      -c <cert nickname>  -s

   Please  note  that  this  is just an example, and that recommended best
   practice is to always store private  keys  in  a  FIPS  140-2  hardware
   security module, level 2 or higher.
