RPMSIGN(8)                                                    RPMSIGN(8)

NAME         top

       rpmsign - RPM Package Signing

SYNOPSIS         top

       rpmsign --addsign|--resign [rpmsign-options] PACKAGE_FILE ...

       rpmsign --delsign PACKAGE_FILE ...

       rpmsign --delfilesign PACKAGE_FILE ...

       [--rpmv3] [--fskpath KEY] [--signfiles]

DESCRIPTION         top

       Both of the --addsign and --resign options generate and insert
       new signatures for each package PACKAGE_FILE given, replacing any
       existing signatures.  There are two options for historical rea‐
       sons, there is no difference in behavior currently.

       To create a signature rpmsign needs to verify the package's
       checksum.  As a result packages with a MD5/SHA1 checksums cannot
       be signed in FIPS mode.

       rpmsign --delsign PACKAGE_FILE ...

       Delete all signatures from each package PACKAGE_FILE given.

       rpmsign --delfilesign PACKAGE_FILE ...

       Delete all IMA and fsverity file signatures from each package
       PACKAGE_FILE given.

              Force RPM V3 header+payload signature addition.  These are
              expensive and redundant baggage on packages where a sepa‐
              rate payload digest exists (packages built with rpm >=
              4.14).  Rpmsign will automatically detect the need for V3
              signatures, but this option can be used to force their
              creation if the packages must be fully signature verifi‐
              able with rpm < 4.14 or other interoperability reasons.

       --fskpath KEY
              Used with --signfiles, use file signing key Key.

       --certpath CERT
              Used with --signverity, use file signing certificate Cert.

       --verityalgo ALG
              Used with --signverity, to specify the signing algorithm.
              sha256 and sha512 are supported, with sha256 being the de‐
              fault if this argument is not specified.  This can also be
              specified with the macro %_verity_algorithm

              Sign package files.  The macro %_binary_filedigest_algo‐
              rithm must be set to a supported algorithm before building
              the package.  The supported algorithms are SHA1, SHA256,
              SHA384, and SHA512, which are represented as 2, 8, 9, and
              10 respectively.  The file signing key (RSA private key)
              must be set before signing the package, it can be config‐
              ured on the command line with --fskpath or the macro

              Sign package files with fsverity signatures.  The file
              signing key (RSA private key) and the signing certificate
              must be set before signing the package.  The key can be
              configured on the command line with --fskpath or the macro
              %_file_signing_key, and the cert can be configured on the
              command line with --certpath or the macro %_file_sign‐

       In order to sign packages, you need to create your own public and
       secret key pair (see the GnuPG manual).  In addition, rpm must be
       configured to find GnuPG and the appropriate keys with the fol‐
       lowing macros:

              The name of the "user" whose key you wish to use to sign
              your packages.  Typically this is the only configuration

              The location of your GnuPG keyring if not the default

       %__gpg The path of the GnuPG executable.  Normally pre-config‐

       For example, to be able to use GnuPG to sign packages as the user
       "John Doe <jdoe@foo.com>" from the key rings located in
       /etc/rpm/.gpg using the executable /opt/bin/gpg you would include

              %_gpg_path /etc/rpm/.gpg
              %_gpg_name John Doe <jdoe@foo.com>
              %__gpg /opt/bin/gpg

       in a macro configuration file, typically ~/.config/rpm/macros.
       See Macro Configuration in rpm(8) for more details.
