+
+	  The gnupg module allows Python programs to make use of the
+	  functionality provided by the GNU Privacy Guard (abbreviated
+	  GPG or GnuPG). Using this module, Python programs can
+	  encrypt and decrypt data, digitally sign documents and
+	  verify digital signatures, manage (generate, list and
+	  delete) encryption keys, using Public Key Infrastructure
+	  (PKI) encryption technology based on OpenPGP.
