DSCVERIFY(1)                           General Commands Manual                          DSCVERIFY(1)



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       Please note that the keyring provided by the debian-keyring package can be  slightly  out  of
       date.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 configu‐
       ration 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
