GnuPG - The GNU Privacy Guard suite of programs DESCRIPTION
GnuPG is a set of programs for public key encryption and digital signatures. The program most users will want to use is the OpenPGP com- mand line tool, named gpg. gpgv is a stripped down version of gpg with no encryption functionality, used only to verify signatures against a trusted keyring. There is also a tool called gpgsplit to split OpenPGP messages or keyrings into their component packets. This is mainly useful for seeing how OpenPGP messages are put together. SEE ALSO

gpgv -- signature verification tool SYNOPSIS
gpgv [options] [signed files] DESCRIPTION
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. OPTIONS
gpgv recognizes these options: -v, --verbose Give more information during processing. If used twice, the input data is listed in detail. -q, --quiet Try to be as quiet as possible. --keyring file Add file to the list of keyrings. If file 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: "gnupg-ring:" is the default one. It might make sense to use it together with --no-default-keyring. --homedir directory Set the name of the home directory to directory 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". --status-fd n Write special status strings to the file descriptor n. See the file DETAILS in the documentation for a listing of them. --logger-fd n Write log output to file descriptor n and not to stderr. --ignore-time-conflict GnuPG normally checks that the timestamps associated with keys and signatures have plausible values. However, sometimes a signa- ture seems to be older than the key due to clock problems. This option makes these checks just a warning. RETURN VALUE
The program returns 0 if everything was fine, 1 if at least one signature was bad, and other error codes for fatal errors. EXAMPLES
gpgv pgpfile 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. ENVIRONMENT
HOME Used to locate the default home directory. GNUPGHOME If set directory used instead of "~/.gnupg". FILES
~/.gnupg/trustedkeys.gpg The default keyring with the allowed keys gpgv(1)
