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 only able to check signatures.	It is somewhat smaller than the full blown gpg and
       uses a different (and more simple way) to check that the public keys used to made the signature are trustworth.	There is no options  files
       and only very few options are implemented.

       gpgv assumes that all keys in the keyring are trustworty.  It uses by default 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
		 Give 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.

		 It might make sense to use it together with --no-default-keyring.

       --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 a 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 signa-
		 ture seems to be older than the key due to clock problems.  This option makes these checks just a warning.

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.

ENVIRONMENT
       HOME	 Used to locate the default home directory.

       GNUPGHOME If set directory used instead of "~/.gnupg".

FILES
       ~/.gnupg/trustedkeys.gpg
		 The default keyring with the allowed keys
