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Please note that the keyring provided by the debian-keyring package can be slightly out of date.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