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       Please note that the keyring provided by the debian-keyring package can be  slightly  out  of
       date.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