pesign - command line tool for signing UEFI applications

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