@subsection Using PGP/MIME
@acronym{PGP/MIME} requires an external OpenPGP implementation, such
implementations such as PGP 2.x and PGP 5.x are also supported. One
Emacs interface to the PGP implementations, PGG (@pxref{Top, ,PGG,
pgg, PGG Manual}), is included, but Mailcrypt and Florian Weimer's
-@code{gpg.el} are also supported.
+@code{gpg.el} are also supported. @xref{PGP Compatibility}.
+
+@cindex gpg-agent
+Message internally calls GnuPG (the @command{gpg} command) to perform
+data encryption, and in certain cases (decrypting or signing for
+example), @command{gpg} requires user's passphrase. Currently the
+recommended way to supply your passphrase to @command{gpg} is to use the
+@command{gpg-agent} program.
+
+To use @command{gpg-agent} in Emacs, you need to run the following
+command from the shell before starting Emacs.
+
+@example
+eval `gpg-agent --daemon`
+@end example
+
+This will invoke @command{gpg-agent} and set the environment variable
+@code{GPG_AGENT_INFO} to allow @command{gpg} to communicate with it.
+It might be good idea to put this command in your @file{.xsession} or
+@file{.bash_profile}. @xref{Invoking GPG-AGENT, , , gnupg, Using the
+GNU Privacy Guard}.
+
+Once your @command{gpg-agent} is set up, it will ask you for a
+passphrase as needed for @command{gpg}. Under the X Window System,
+you will see a new passphrase input dialog appear. The dialog is
+provided by PIN Entry (the @command{pinentry} command), and as of
+version 0.7.2, @command{pinentry} cannot cooperate with Emacs on a
+single tty. So, if you are using a text console, you may need to put
+a passphrase into gpg-agent's cache beforehand. The following command
+does the trick.
+
+@example
+gpg --use-agent --sign < /dev/null > /dev/null
+@end example
+
+The Lisp variable @code{pgg-gpg-use-agent} controls whether to use
+@command{gpg-agent}. See also @xref{Caching passphrase, , , pgg, The
+PGG Manual}.
