RPMSIGN(1) General Commands Manual RPMSIGN(1)
rpmsign - RPM Package Signing
rpmsign {--addsign|--resign} [options] [sign-options] PACKAGE_FILE
...
rpmsign --delsign [options] PACKAGE_FILE ...
rpmsign --delfilesign [options] PACKAGE_FILE ...
rpmsign is used to manipulate digital OpenPGP signatures on rpm
package files.
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.
--addsign
Generate and insert 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.
--resign
Generates and inserts a new OpenPGP signature for each
PACKAGE_FILE, replacing any and all previous signatures.
--delsign
Delete all OpenPGP signatures from each package PACKAGE_FILE
given.
--delfilesign
Delete all IMA and fsverity file signatures from each package
PACKAGE_FILE given.
PACKAGE_FILE
An rpm package file.
See rpm-common(8) for the options common to all rpm executables.
--certpath CERT
Used with --signverity, use file signing certificate CERT.
--fskpath KEY
Used with --signfiles, use file signing key KEY.
--key-id KEYID
Use key KEYID for signing. Overrides %_openpgp_sign_id
configuration.
--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 using the same logic as --rpmv4 on a V6
package.
Has no effect when signing V6 packages.
--signfiles
Sign package files. 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.
--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.
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.
Example 1. Basic setup
Configure RPM to sign packages with Sequoia PGP and a specific key
by adding the following contents to the user's rpm-config(5) file
(typically ~/.config/rpm/macros):
%_openpgp_sign sq
%_openpgp_sign_id 7B36C3EE0CCE86EDBC3EFF2685B274E29F798E08
Example 2. Basic operations
rpmsign --addsign hello-2.0-1.x64_rpm
Add a signature to hello-2.0-1.x64_rpm package.
rpmsign --resign --key-id 771b18d3d7baa28734333c424344591e1964c5fc
hello-2.0-1.x64_rpm
Replace all signatures in hello-2.0-1.x64_rpm package by a
signature using key 771b18d3d7baa28734333c424344591e1964c5fc.
rpmsign --delsign --delfilesign hello-2.0-1.x64_rpm
Delete all signatures from hello-2.0-1.x64_rpm package.
On success, 0 is returned, a nonzero failure code otherwise.
popt(3), rpm(8), rpm-common(8), rpmkeys(8), rpmbuild(1)
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.
