DEBSIGN(1)                  General Commands Manual                 DEBSIGN(1)

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

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

DESCRIPTION
       debsign  mimics the signing aspects (and bugs) of dpkg-buildpackage(1).
       It takes a .dsc, .buildinfo, or .changes file and  signs  it,  and  any
       child .dsc, .buildinfo, or .changes files directly or indirectly refer-
       enced by it, using the GNU Privacy Guard. It is  careful  to  calculate
       the  size and checksums of any newly signed child files and replace the
       original values in the parent file.

       If no file is specified, 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.upload.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,  .buildinfo  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).  However note that it is probably safer
       to have your trusted signing machine use  debsign  to  connect  to  the
       untrusted  non-signing  machine, rather than using debrsign to make the
       connection in the reverse direction.

       This program can take default settings from the  devscripts  configura-
       tion files, as described below.

OPTIONS
       -r [username@]remotehost
              The  files  to  be signed live on the specified remote host.  In
              this case, a .dsc, .buildinfo or .changes file must  be  explic-
              itly  named,  with  an absolute directory or one relative to the
              remote home directory.  scp will be used for the  copying.   The
              [username@]remotehost:filename  syntax is permitted as an alter-
              native.  Wildcards (* etc.) are allowed.

       -pprogname
              When debsign needs to execute GPG to sign it will  run  progname
              (searching the PATH if necessary), instead of gpg.

       -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.

       -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 debsign should  use
              the   most  recent  file  with  the  name  pattern  package_ver-
              sion_*+*.changes as the .changes file, allowing for the .changes
              files produced by dpkg-cross.

       --re-sign, --no-re-sign
              Recreate  signature, respectively use the existing signature, if
              the file has been signed already.  If neither  option  is  given
              and  an  already signed file is found the user is asked if he or
              she likes to use the current signature.

       --debs-dir DIR
              Look for the files to be signed in directory DIR instead of  the
              parent  of the source directory.  This should either be an abso-
              lute path or relative to the top of the source directory.

       --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.  Environ-
       ment variable settings are ignored for  this  purpose.   The  currently
       recognised variables are:

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

       DEBSIGN_MAINT
              This is the -m option.

       DEBSIGN_KEYID
              And this is the -k option.

       DEBSIGN_ALWAYS_RESIGN
              Always  re-sign  files  even if they are already signed, without
              prompting.

       DEBRELEASE_DEBS_DIR
              This specifies the directory in which to look for the  files  to
              be signed, and is either an absolute path or relative to the top
              of the source tree.  This corresponds to the --debs-dir  command
              line  option.  This directive could be used, for example, if you
              always use pbuilder or svn-buildpackage to build your  packages.
              Note  that  it also affects debrelease(1) in the same way, hence
              the strange name of the option.
