gpgv -- signature verification tool
29
`gpgv' is the OpenPGP signature checking tool.
31
This program is a stripped down version of `gpg' which is able only
32
to check signatures. It is somewhat smaller than the fully blown `gpg'
33
and uses a different (and simpler) way to check that the public keys
34
used to make the signature are trustworthy. There are no options files
35
and only very few options are implemented.
37
`gpgv' assumes that all keys in the keyring are trustworthy. By
38
default it uses a keyring named `trustedkeys.gpg' which is assumed to
39
be in the home directory as defined by GnuPG or set by an option or an
40
environment variable. An option may be used to specify another keyring
41
or even multiple keyrings.
46
`gpgv' recognizes these options:
49
Gives more information during processing. If used twice, the input
50
data is listed in detail.
53
Try to be as quiet as possible.
56
Add `file' to the list of keyrings. If `file' begins with a tilde
57
and a slash, these are replaced by the HOME directory. If the
58
filename does not contain a slash, it is assumed to be in the
59
home-directory ("~/.gnupg" if -homedir is not used). The filename
60
may be prefixed with a scheme:
62
"gnupg-ring:" is the default one.
65
Set the name of the home directory to `directory' If this option
66
is not used, it defaults to "~/.gnupg". It does not make sense to
67
use this in an options file. This also overrides the environment
71
Write special status strings to the file descriptor `n'. See the
72
file DETAILS in the documentation for a listing of them.
75
Write log output to file descriptor `n' and not to stderr.
78
GnuPG normally checks that the timestamps associated with keys and
79
signatures have plausible values. However, sometimes a signature
80
seems to be older than the key due to clock problems. This option
81
makes these checks just warnings.
86
The program returns 0 if everything was fine, 1 if at least one
87
signature was bad, and other error codes for fatal errors.
94
Verify the signature of the file. The second form is used for
95
detached signatures, where `sigfile' is the detached signature
96
(either ASCII armored or binary) and are the signed data; if this
97
is not given the name of the file holding the signed data is
98
constructed by cutting off the extension (".asc", ".sig" or
99
".sign") from `sigfile'.

Used to locate the default home directory.
