Linux in a Nutshell, 6th Edition

Name

gpgv

Synopsis

gpgv [options] [detached-signature] [signed-files]

Check the signature of one or more OpenPGP-signed files. This is similar in operation to gpg --verify but uses a different keyring, ˜/.gnupg/trustedkeys.gpg by default. Also, gpgv assumes that the keyring is trusted, and it cannot edit or update it. By contrast, gpg --verify can go to a keyserver to verify signatures that are not in the local keyring, and offers various levels of trust. In both cases, you can use a detached signature file

Options

-h, -?, --help

Display a short help message.

--ignore-time-conflict

Use this flag to ignore incorrect dates on signatures. An incorrect date can be a sign of fraud, but is often just a result of an incorrectly set clock.

--keyring file

Use the specified file as a keyring, in addition to the default ~/.gnupg/trustedkeys.gpg.

--homedir dir

Use the specified directory as the GPG home directory, instead of the default (set in the GNUPGHOME variable, or, if that is unset, ˜/.gnupg).

--logger-fd FD

Send log output to the specified file descriptor. By default, log output goes to stderr. Use of file descriptors is described in the DETAILS section of the GPG documentation.

-q, --quiet

Minimal output.

--status-fd FD

Send special status messages to the specified file descriptor.

-v, --verbose

Verbose mode. More informative.
