[--force | -f] [--sign | -s] [--hash | -h]
[--digest_type=digest | -d digest]
[--show-signature | -S ] [--remove-signature | -r ]
[--export-pubkey=outkey | -K outkey]

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.
