<title>DESCRIPTION</title>
|
|
<para>
|
|
<command/gpgv/ is the OpenPGP signature checking tool.
|
|
</para>
|
|
<para>
|
|
This program is a stripped down version of <command/gpg/ which is only
|
|
able
|
|
to check signatures. It is somewhat smaller than the full blown
|
|
<command/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.
|
|
</para>
|
|
<para>
|
|
<command/gpgv/ assumes that all keys in the keyring are trustworty.
|
|
It uses by default a keyring named <filename/trustedkeys.gpg/ which is
|
|
assumed to be in the home directory as defined by GnuPG or set by an
|
|
option or an environment variable. An option may be used to specify
|
|
another keyring or even multiple keyrings.

<term>--keyring &ParmFile;</term>

|
<listitem><para>
|
|
Add &ParmFile to the list of keyrings.
|
|
If &ParmFile 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:</para>
|
|
<para>"gnupg-ring:" is the default one.</para>
|
|
<para>It might make sense to use it together with --no-default-keyring.

<listitem><para>
|
|
Set the name of the home directory to &ParmDir; If this
|
|
option is not used it defaults to "~/.gnupg". It does
|
|
not make sense to use this in a options file. This
|
|
also overrides the environment variable "GNUPGHOME".

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

<para>
|

The program returns 0 if everything was fine, 1 if at least

one signature was bad, and other error codes for fatal errors.

Verify the signature of the file. The second form

is used for detached signatures, where <parameter/sigfile/ is the detached

|
signature (either ASCII armored or binary) and &OptParmFiles 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
|
|
<parameter/sigfile/.
