      The GNU Privacy Guard is the GNU project's complete and free
      implementation of the OpenPGP standard as defined by RFC4880.  GnuPG
      "modern" (2.1) is the latest development with a lot of new features.
      GnuPG allows to encrypt and sign your data and communication, features a
      versatile key management system as well as access modules for all kind of
      public key directories.  GnuPG, also known as GPG, is a command line tool
      with features for easy integration with other applications.  A wealth of
      frontend applications and libraries are available.  Version 2 of GnuPG
      also provides support for S/MIME.
