NAME
gpgv --- signature verification tool
SYNOPSIS
gpgv [options] [signed files]
DESCRIPTION
gpgv is the OpenPGP signature checking tool.
This program is a stripped down version of gpg which is able
only
to check signatures. It is somewhat smaller than the fully blown
gpg and uses a different (and simpler) way to check that
the public keys used to make the signature are trustworthy. There are
no options files and only very few options are implemented.
gpgv assumes that all keys in the keyring are trustworthy.
By default it uses a keyring named trustedkeys.gpg which is
assumed to be in the home directory as defined by GnuPG or set by an
option or an environment variable. An option may be used to specify
another keyring or even multiple keyrings.
OPTIONS
gpgv recognizes these options:
-v, --verbose
Gives more information during processing. If used
twice, the input data is listed in detail.
-q, --quiet
Try to be as quiet as possible.
--keyring file
Add file to the list of keyrings.
If file begins with a tilde and a slash, these
are replaced by the HOME directory. If the filename
does not contain a slash, it is assumed to be in the
home-directory ("~/.gnupg" if --homedir is not used).
The filename may be prefixed with a scheme:
"gnupg-ring:" is the default one.
--homedir directory
Set the name of the home directory to directory If this
option is not used, it defaults to "~/.gnupg". It does
not make sense to use this in an options file. This
also overrides the environment variable "GNUPGHOME".
--status-fd n
Write special status strings to the file descriptor n.
See the file DETAILS in the documentation for a listing of them.
--logger-fd n
Write log output to file descriptor n and not to stderr.
--ignore-time-conflict
GnuPG normally checks that the timestamps associated with keys and
signatures have plausible values. However, sometimes a signature seems to
be older than the key due to clock problems. This option makes these
checks just warnings.
RETURN VALUE
The program returns 0 if everything was fine, 1 if at least
one signature was bad, and other error codes for fatal errors.
EXAMPLES
gpgv pgpfile
gpgv sigfile [files]
Verify the signature of the file. The second form
is used for detached signatures, where sigfile is the detached
signature (either ASCII armored or binary) and [files] are the signed
data; if this is not given the name of the file holding the signed data is
constructed by cutting off the extension (".asc", ".sig" or ".sign") from
sigfile.
