- 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 environ-
- ment 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 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.
-
- --ignore-time-conflict
- 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 warnings.
-
- RETURN VALUE
- The program returns 0 if everything was fine, 1 if at least one signa-
- ture 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
