gpgv

Description

GNU privacy guard - signature verification tool
GnuPG is GNU's tool for secure communication and data storage.

gpgv is actually a stripped-down version of gpg which is only able
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 valid. There are no configuration
files and only a few options are implemented.
