gpgv [options] [signed files]
gpgv is the OpenPGP signature checking tool.
This program is a stripped down version of gpg which is only able to check signatures. It is somewhat smaller than the full blown 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.
gpgv assumes that all keys in the keyring are trustworty. It uses by default a keyring named 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.
gpgv recognizes these options:
The program returns 0 if everything was fine, 1 if at least one signature was bad, and other error codes for fatal errors.
