gpgv2 2.0.26-6ubuntu1 (ppc64el binary) in ubuntu wily

 GnuPG is GNU's tool for secure communication and data storage.
 .
 gpgv2 is actually a stripped-down version of gpg2 which is only able
 to check signatures. It is somewhat smaller than the fully-blown gpg2
 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.
