RPMSIGN(8)

NAME
rpmsign - RPM Package Signing

SYNOPSIS

  SIGNING PACKAGES:

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

  rpmsign-options

[--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.

  SIGN OPTIONS

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

--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.

  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. http://www.rpm.org/ <URL:http://www.rpm.org/>
