gpgv

gpgv

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. 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.
-k,--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.
