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 signatures 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 PACKAGE_FILE given.

   SIGN OPTIONS
       --rpmv3
              Force RPM V3 header+payload signature addition.  These are expensive and  redundant
              baggage on packages where a separate payload 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 fully signature
              verifiable 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 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.

   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 create 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 configuration and
       ~/.rpmmacros  for  per-user  configuration.   Typically  it's  sufficient  to   set   just
       %_gpg_name.

       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.
