NAME

       dscverify - verify the validity of a Debian package

SYNOPSIS

       dscverify [--keyring keyring] ... changes_or_buildinfo_or_dsc_filename ...

DESCRIPTION

       dscverify  checks  that the GPG signatures on the given .changes, .buildinfo or .dsc files
       are good signatures made by keys in the current Debian  keyrings,  found  in  the  debian-
       keyring  package.   (Additional  keyrings  can be specified using the --keyring option any
       number of times.)  It then checks that the other files listed in the .changes,  .buildinfo
       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, .buildinfo 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       Please note that the keyring provided by the debian-keyring package can be slightly out of
       date.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

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

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

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

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