NAME

   dscverify - verify the validity of a Debian package

SYNOPSIS

   dscverify [--keyring keyring] ... changes_or_dsc_filename ...

DESCRIPTION

   dscverify  checks that the GPG signatures on the given .changes or .dsc
   files are good signatures made by keys in the current Debian  keyrings,
   found   in   the   debian-keyring   and   debian-maintainers  packages.
   (Additional keyrings can be specified using the  --keyring  option  any
   number  of  times.)   It then checks that the other files listed in the
   .changes or .dsc files have the correct sizes and checksums  (MD5  plus
   SHA1  and  SHA256  if the latter are present).  The exit status is 0 if
   there are no problems and non-zero otherwise.

OPTIONS

   --keyring keyring
          Add keyring to the list of keyrings to be used.

   --no-default-keyrings
          Do not use the default set of keyrings.

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

   --nosigcheck, --no-sig-check, -u
          Skip  the  signature verification step. That is, only verify the
          sizes and checksums of the files listed in the .changes or  .dsc
          files.

   --verbose
          Do not suppress GPG output.

   --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  by  a  shell  in  that order to set
   configuration  variables.   Environment  variable  settings  are
   ignored  for  this  purpose.   If  the first command line option
   given is --noconf or --no-conf, then these  files  will  not  be
   read.  The currently recognised variable is:

   DSCVERIFY_KEYRINGS
          This  is  a colon-separated list of extra keyrings to use
          in addition to any specified on the command line.

KEYRING

   Please note that the  keyring  provided  by  the  debian-keyring
   package  can  be slightly out of date. The latest version can be
   obtained with rsync, as documented in the README that comes with
   debian-keyring.   If  you  sync  the  keyring  to a non-standard
   location (see below), you can use the possibilities  to  specify
   extra   keyrings,   by   either   using   the   above  mentioned
   configuration option or the --keyring option.

   Below is an example for an alias:

   alias dscverify='dscverify --keyring ~/.gnupg/pubring.gpg'

STANDARD KEYRING LOCATIONS

   By default dscverify searches  for  the  debian-keyring  in  the
   following locations:

   - ~/.gnupg/trustedkeys.gpg

   - /org/keyring.debian.org/keyrings/debian-keyring.gpg

   - /usr/share/keyrings/debian-keyring.gpg

   - /usr/share/keyrings/debian-maintainers.gpg

SEE ALSO

   gpg(1), gpg2(1), devscripts.conf(5)
