 By default, PGG uses GnuPG, but Pretty Good Privacy version 2 or version
 5 are also supported.  If you are new to such a system, I recommend that
 you should look over the GNU Privacy Handbook (GPH) which is available

+When using GnuPG the additional use of the gpg-agent (@pxref{Caching
+passphrase}) is highly recommended, as it provides the most secure way
+for input and caching of passphrases.  Please refer to the documentation
+of GnuPG for details on installation and usage.
