GPGV linux command manual

gpgv(1)                                                                gpgv(1)

       gpgv -- signature verification tool

       gpgv  [options]  [signed files]

       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 environ-
       ment variable.  An option may be used to specify  another  keyring  or
       even multiple keyrings.

       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-

       --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 over-
                 rides 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.

                 GnuPG normally checks that the  timestamps  associated  with
                 keys  and  signatures have plausible values.  However, some-
                 times a signature seems to be older  than  the  key  due  to
                 clock  problems.   This  option  makes  these  checks just a

       The program returns 0 if everything was fine, 1 if at least one signa-
       ture was bad, and other error codes for fatal errors.

       gpgv pgpfile

       gpgv sigfile [files]
                 Verify  the  signature  of the file. The second form is used
                 for detached signatures, where sigfile is the detached  sig-
                 nature  (either ASCII armored or binary) and [files] are the
                 signed data; if this is not given the name of the file hold-
                 ing the signed data is constructed by cutting off the exten-
                 sion (".asc", ".sig" or ".sign") from sigfile.

       HOME      Used to locate the default home directory.

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