NAME
rpmsign - RPM Package Signing
SYNOPSIS
SIGNING PACKAGES:
rpm --addsign|--resign [rpmsign-options] PACKAGE_FILE ...
rpm --delsign PACKAGE_FILE ...
rpm --delfilesign PACKAGE_FILE ...
rpmsign-options
[--rpmv3] [--fskpath KEY] [--signfiles]
DESCRIPTION
Both of the --addsign and --resign options generate and insert new sig-
natures for each package PACKAGE_FILE given, replacing any existing
signatures. There are two options for historical reasons, there is no
difference in behavior currently.
To create a signature rpm needs to verify the package's checksum. As a
result packages with a MD5/SHA1 checksums cannot be signed in FIPS
mode.
rpm --delsign PACKAGE_FILE ...
Delete all signatures from each package PACKAGE_FILE given.
rpm --delfilesign PACKAGE_FILE ...
Delete all IMA and fsverity file signatures from each package PACK-
AGE_FILE given.
SIGN OPTIONS
--rpmv3
Force RPM V3 header+payload signature addition. These are ex-
pensive and redundant baggage on packages where a separate pay-
load digest exists (packages built with rpm >= 4.14). Rpm will
automatically detect the need for V3 signatures, but this option
can be used to force their creation if the packages must be ful-
ly signature verifiable with rpm < 4.14 or other interoperabili-
ty 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 default
if this argument is not specified. This can also be specified
with the macro %_verity_algorithm
--signfiles
Sign package files. The macro %_binary_filedigest_algorithm
must be set to a supported algorithm before building the pack-
age. 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 sign-
ing the package, it can be configured on the command line with
--fskpath or the macro %_file_signing_key.
--signverity
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_signing_cert.
USING GPG TO SIGN PACKAGES
In order to sign packages using GPG, rpm must be configured to run GPG
and be able to find a key ring with the appropriate keys. By default,
rpm uses the same conventions as GPG to find key rings, namely the
$GNUPGHOME environment variable. If your key rings are not located
where GPG expects them to be, you will need to configure the macro
%_gpg_path to be the location of the GPG key rings to use. If you want
to be able to sign packages you create yourself, you also need to cre-
ate your own public and secret key pair (see the GPG manual). You will
also need to configure the rpm macros
%_gpg_name
The name of the "user" whose key you wish to use to sign your
packages.
For example, to be able to use GPG to sign packages as the user "John
Doe <jdoe@foo.com>" from the key rings located in /etc/rpm/.gpg using
the executable /usr/bin/gpg you would include
%_gpg_path /etc/rpm/.gpg
%_gpg_name John Doe <jdoe@foo.com>
%__gpg /usr/bin/gpg
in a macro configuration file. Use /etc/rpm/macros for per-system con-
figuration and ~/.rpmmacros for per-user configuration. Typically it's
sufficient to set just %_gpg_name.

aliases it's impossible to guarantee that what's described in the manu-
al matches what's available.
