RPMSIGN(8) RPMSIGN(8)
rpmsign - RPM Package Signing
SIGNING PACKAGES:
rpmsign --addsign|--resign [rpmsign-options] PACKAGE_FILE ...
rpmsign --delsign PACKAGE_FILE ...
rpmsign --delfilesign PACKAGE_FILE ...
rpmsign-options
[--rpmv3] [--rpmv4] [--fskpath KEY] [--signfiles]
rpmsign --addsign generates and inserts a new OpenPGP signature
for each PACKAGE_FILE given unless a signature with identical
parameters already exists, in which case no action is taken.
Arbitrary number of V6 signatures can be added.
rpmsign --resign generates and inserts a new OpenPGP signature for
each PACKAGE_FILE, replacing any and all previous signatures.
To create a signature rpmsign needs to verify the package's
checksum. As a result V4 packages with MD5/SHA1 checksums cannot
be signed in FIPS mode.
rpmsign --delsign PACKAGE_FILE ...
Delete all OpenPGP signatures from each package PACKAGE_FILE
given.
rpmsign --delfilesign PACKAGE_FILE ...
Delete all IMA and fsverity file signatures from each package
PACKAGE_FILE given.
SIGN OPTIONS
--rpmv3
Request RPM V3 header+payload signature addition on V4
packages. These signatures are expensive and redundant
baggage on packages where a separate 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 request their creation if the
packages must be fully signature verifiable with rpm < 4.14
or other interoperability reasons.
Has no effect when signing V6 packages.
--rpmv4
Request RPM V4 header signature addition on V6 packages.
Useful for making V6 packages signature verifiable with rpm
4.x versions.
V4 compatibility signatures are only ever added if the
signing algorithm is one of those known to V4: RSA, EcDSA,
EdDSA (and original DSA). Only one V4 signature can be
present in a package, so this is added only on the first
--addsign with a V4 compatible algorithm, and ignored
otherwise.
Has no effect when signing V4 packages.
--rpmv6
Request RPM V6 header signature addition on V4 packages.
This generally always succeeds as there can be arbitrary
number of V6 signatures on a package. A V3/V4
compatibility signatures are added usign the same logic as
--rpmv4 on a V6 package.
Has no effect when signing V6 packages.
--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 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 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.
CONFIGURING SIGNING KEYS
In order to sign packages, you need to create your own OpenPGP key
pair (aka certificate) and configure rpm(8) to use it. The
following macros are available:
%_openpgp_sign_id
The fingerprint or keyid of the signing key to use.
Typically this is the only configuration needed. If
omitted, –key-id must be explicitly specified when signing.
%_openpgp_sign
The OpenPGP implementation to use for signing. Supported
values are "gpg" for GnuPG (default and traditional) and
"sq" for Sequoia PGP.
Implementation specific macros:
%_gpg_path
The location of your GnuPG keyring if not the default
$GNUPGHOME.
%_gpg_name
Legacy macro for configuring user id with GnuPG. Use the
implementation independent and non-ambiguous
%_openpgp_sign_id instead.
%_sq_path
The location of your Sequoia configuration if not the
default.
For example, to configure rpm to sign with Sequoia PGP using a key
with fingerprint of 7B36C3EE0CCE86EDBC3EFF2685B274E29F798E08 you
would include
%_openpgp_sign sq %_openpgp_signer
7B36C3EE0CCE86EDBC3EFF2685B274E29F798E08
in a macro configuration file, typically ~/.config/rpm/macros.
See Macro Configuration in rpm(8) for more details.

rpmsign --help - as rpm supports customizing the options via popt
aliases it's impossible to guarantee that what's described in the
manual matches what's available.
