       dscverify - verify the validity of a Debian package


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


       dscverify  checks  that the GPG or PGP 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.


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

              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

              Do not suppress GPG output.

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

              Display   version  and  copyright  information  and  exit


       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:

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


       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       package  can  be slightly out of date.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'


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

       - /org/|pgp)

       - /usr/share/keyrings/debian-keyring.(pgp|gpg)

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


       gpg(1) and devscripts.conf(5).
