DEBSIGN(1)

NAME
debsign - sign a Debian changes and dsc file pair using GPG/PGP

SYNOPSIS
debsign [options] [changes-file|dsc-file|commands-file]

DESCRIPTION
debsign mimics the signing aspects (and bugs) of dpkg-buildpackage(1). It takes either an unsigned .dsc file or an unsigned .changes file (along with the associated unsigned .dsc file found by replacing the architecture name and .changes by .dsc if it appears in the .changes file), and signs them using the GNU Privacy Guard or PGP. It is careful to calculate the size and MD5 sum of the newly signed .dsc file and replace the original values in the .changes file.

If a .changes, .dsc or .commands file is specified, it is signed, otherwise, debian/changelog is parsed to determine the name of the .changes file to look for in the parent directory.

If a .commands file is specified it is first validated (see the details at ftp://ftp-master.debian.org/pub/UploadQueue/README), and the name specified in the Uploader field is used for signing.

This utility is useful if a developer must build a package on one machine where it is unsafe to sign it; they need then only transfer the small .dsc and .changes files to a safe machine and then use the debsign program to sign them before transferring them back. This process can be automated in two ways. If the files to be signed live on the remote machine, the -r option may be used to copy them to the local machine and back again after signing. If the files live on the local machine, then they may be transferred to the remote machine for signing using debrsign(1).

This program can take default settings from the devscripts configuration files, as described below.

OPTIONS

-r [username@]remotehost
    The .changes and .dsc files live on the specified remote host. In this case, a .changes file must be explicitly named, with an absolute directory or one relative to the remote home directory. SSH will be used for the copying. The [username@]remotehost:changes syntax is permitted as an alternative.

-pprogname
    progname is one of pgp or gpg, and specifies which signing program is to be called. The default is gpg if ~/.gnupg/secring.gpg exists and pgp otherwise.

-mmaintainer
    Specify the maintainer name to be used for signing. (See dpkg-buildpackage(1) for more information about the differences between -m, -e and -k when building packages; debsign makes no use of these distinctions except with respect to the precedence of the various options. These multiple options are provided so that the program will behave as expected when called by debuild(1).)

-emaintainer
    Same as -m but takes precedence over it.

-kkeyid
    Specify the key ID to be used for signing; overrides any -m and -e options.

-spgp, -sgpg
    Whether the signing program is to be called with command line arguments like those of pgp or gpg.

-S  Look for a source-only .changes file instead of a binary-build changes file.

-adebian-architecture, -tGNU-system-type
    See dpkg-architecture(1) for a description of these options. They affect the search for the .changes file. They are provided to mimic the behaviour of dpkg-buildpackage when determining the name of the .changes file.

--multi
    Multiarch changes mode: This signifies that debrsign should use the most recent file with the name pattern package_version_*+*.changes as the changes file, allowing for the changes files produced by dpkg-cross.

--no-conf, --noconf
    Do not read any configuration files. This can only be used as the first option given on the command-line.

--help, -h
    Display a help message and exit successfully.

--version
    Display version and copyright information and exit successfully.

CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced in that order to set configuration variables. Command line options can be used to override configuration file settings. Environment variable settings are ignored for this purpose. The currently recognised variables are:

DEBSIGN_PROGRAM
    Setting this is equivalent to giving a -p option.

DEBSIGN_SIGNLIKE
    This must be gpg or pgp and is equivalent to using either -sgpg or -spgp respectively.

DEBSIGN_MAINT
    This is the -m option.

DEBSIGN_KEYID
    And this is the -k option.
