- NAME
- gpgv - Verify OpenPGP signatures
-
- SYNOPSIS
- gpgv [_______] ____________
-
-
-
-
-
- DESCRIPTION
- gpgv is an OpenPGP signature verification tool.
-
- This program is actually a stripped down version of gpg which is only
- able 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 valid. There are no configuration
- files and only a few options are implemented.
-
- gpgv assumes that all keys in the keyring are trustworthy. By default
- it uses a keyring named `_______________' 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.
-
-
-
- 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.
-
-
- OPTIONS
- gpgv recognizes these options:
-
-
-
- --verbose
-
- -v Gives more information during processing. If used twice, the
- input data is listed in detail.
-
-
- --quiet
-
- -q Try to be as quiet as possible.
-
-
- --keyring ____
- Add ____ to the list of keyrings. If ____ 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).
-
-
- --status-fd _
- Write special status strings to the file descriptor _. 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 sig-
- nature seems to be older than the key due to clock problems.
- This option turns these checks into warnings.
-
-
- --homedir ___
- Set the name of the home directory to ___. If his option is not
- used, the home directory defaults to `________'. It is only
- recognized when given on the command line. It also overrides
- any home directory stated through the environment variable
- `_________' or (on W32 systems) by means on the Registry entry
- _______________________________.

- EXAMPLES
- gpgv pgpfile
-
- gpgv sigfile
- 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 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.
-
-
-
- FILES
- ~/.gnupg/trustedkeys.gpg
- The default keyring with the allowed keys
-
-
-
- ENVIRONMENT
- HOME Used to locate the default home directory.
-
-
- GNUPGHOME
- If set directory used instead of "~/.gnupg".

- The full documentation for this tool is maintained as a Texinfo manual.
- If GnuPG and the info program are properly installed at your site, the
- command
-
- info gnupg1
-
- should give you access to the complete manual including a menu struc-
- ture and an index.
