gpgv -- signature verification tool
gpgv [options] [signed files]
gpgv is the OpenPGP signature checking tool.
This program is a stripped down version of gpg which is able only to check signatures. It is somewhat smaller than the fully blown gpg and uses a different (and simpler) way to check that the public keys used to make the signature are trustworthy. There are no options files and only very few options are implemented.
gpgv assumes that all keys in the keyring are trustworthy. By default it uses 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:
“gnupg-ring:” is the default one.
The program returns 0 if everything was fine, 1 if at least one signature was bad, and other error codes for fatal errors.
gpgv sigfile [files]
Verify the signature of the file. The second form is used for detached signatures, where sigfile is the detached signature (either ASCII armored or binary) and [files] 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 sigfile.
GNUPGHOME If set directory used instead of “~/.gnupg".
