Binary package “gpgv” in ubuntu trusty

GNU privacy guard - signature verification tool

 GnuPG is GNU's tool for secure communication and data storage.
 gpgv is a stripped-down version of gnupg which is only able to check
 signatures. It is smaller than the full-blown gnupg and uses a
 different (and simpler) way to check that the public keys used to
 make the signature are trustworthy.
