\fBgpgv\fR [\fBoptions\fR] [\fBsigned files\fR]
11
\fBgpgv\fR is the OpenPGP signature checking tool.
14
This program is a stripped down version of \fBgpg\fR which is able
16
to check signatures. It is somewhat smaller than the fully blown
17
\fBgpg\fR and uses a different (and simpler) way to check that
18
the public keys used to make the signature are trustworthy. There are
19
no options files and only very few options are implemented.
21
\fBgpgv\fR assumes that all keys in the keyring are trustworthy.
22
By default it uses a keyring named \fBtrustedkeys.gpg\fP which is
23
assumed to be in the home directory as defined by GnuPG or set by an
24
option or an environment variable. An option may be used to specify
25
another keyring or even multiple keyrings.
28
\fBgpgv\fR recognizes these options:
29
.IP "\-v, \-\-verbose" 10
30
Gives more information during processing. If used
31
twice, the input data is listed in detail.
32
.IP "\-q, \-\-quiet" 10
33
Try to be as quiet as possible.
34
.IP "\-\-keyring \fBfile\fR" 10
35
Add \fBfile\fR to the list of keyrings.
36
If \fBfile\fR begins with a tilde and a slash, these
37
are replaced by the HOME directory. If the filename
38
does not contain a slash, it is assumed to be in the
39
home-directory ("~/.gnupg" if \-\-homedir is not used).
40
The filename may be prefixed with a scheme:
42
"gnupg-ring:" is the default one.
43
.IP "\-\-homedir \fBdirectory\fR" 10
44
Set the name of the home directory to \fBdirectory\fR If this
45
option is not used, it defaults to "~/.gnupg". It does
46
not make sense to use this in an options file. This
47
also overrides the environment variable "GNUPGHOME".
48
.IP "\-\-status-fd \fBn\fR" 10
49
Write special status strings to the file descriptor \fBn\fR.
50
See the file DETAILS in the documentation for a listing of them.
51
.IP "\-\-logger-fd \fBn\fR" 10
52
Write log output to file descriptor \fBn\fR and not to stderr.
53
.IP "\-\-ignore-time-conflict" 10
54
GnuPG normally checks that the timestamps associated with keys and
55
signatures have plausible values. However, sometimes a signature seems to
56
be older than the key due to clock problems. This option makes these
60
The program returns 0 if everything was fine, 1 if at least
61
one signature was bad, and other error codes for fatal errors.
64
.IP "gpgv \fBpgpfile\fR" 10
65
.IP "gpgv \fBsigfile\fR [\fBfiles\fR]" 10
66
Verify the signature of the file. The second form
67
is used for detached signatures, where \fBsigfile\fR is the detached
68
signature (either ASCII armored or binary) and [\fBfiles\fR] are the signed
69
data; if this is not given the name of the file holding the signed data is
70
constructed by cutting off the extension (".asc", ".sig" or ".sign") from
74
Used to locate the default home directory.
76
If set directory used instead of "~/.gnupg".
78
.IP "~/.gnupg/trustedkeys.gpg" 10
79
The default keyring with the allowed keys
