-@vindex mml-signencrypt-style-alist
-By default, when encrypting a message, Gnus will use the
-``signencrypt'' mode. If you would like to disable this for a
-particular message, give the @code{mml-secure-message-encrypt-*}
-command a prefix argument. (for example, @kbd{C-u C-c C-m c p}).
-Additionally, by default Gnus will separately sign, then encrypt a
-message which has the mode signencrypt. If you would like to change
-this behavior you can customize the @code{mml-signencrypt-style-alist}
-variable. For example:
-
-
-@lisp
-(setq mml-signencrypt-style-alist '(("smime" combined)
- ("pgp" combined)
- ("pgpmime" combined)))
-@end lisp
-
-Will cause Gnus to sign and encrypt in one pass, thus generating a
-single signed and encrypted part. Note that combined sign and encrypt
-does not work with all supported OpenPGP implementations (in
-particular, @acronym{PGP} version 2 do not support this).
-
Since signing and especially encryption often is used when sensitive
information is sent, you may want to have some way to ensure that your
mail is actually signed or encrypted. After invoking the above
RFC822 headers. They only operate on the @acronym{MIME} object. Keep this
in mind before sending mail with a sensitive Subject line.
+By default, when encrypting a message, Gnus will use the
+``signencrypt'' mode, which means the message is both signed and
+encrypted. If you would like to disable this for a particular
+message, give the @code{mml-secure-message-encrypt-*} command a prefix
+argument, e.g., @kbd{C-u C-c C-m c p}.

Actually using the security commands above is not very difficult. At
least not compared with making sure all involved programs talk with each
other properly. Thus, we now describe what external libraries or
so on.
The @acronym{S/MIME} support in Message (and MML) require OpenSSL. OpenSSL

should work. Version 0.9.5a cannot extract mail addresses from
certificates, and it insert a spurious CR character into @acronym{MIME}
The @file{key+cert.pem} file should be pointed to from the
@code{smime-keys} variable. You should now be able to send signed mail.

@subsection Using PGP/MIME
@acronym{PGP/MIME} requires an external OpenPGP implementation, such
-as @uref{http://www.gnupg.org/, GNU Privacy Guard}. One Emacs
-interface to OpenPGP implementations, PGG (@pxref{Top, ,PGG, pgg, PGG
-Manual}), is included, but Mailcrypt and Florian Weimer's
+as @uref{http://www.gnupg.org/, GNU Privacy Guard}. Pre-OpenPGP
+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.

0700.

+
+If you have imported your old PGP 2.x key into GnuPG, and want to send
+signed and encrypted messages to your fellow PGP 2.x users, you'll
+discover that the receiver cannot understand what you send. One
+solution is to use PGP 2.x instead (i.e., if you use @code{pgg}, set
+@code{pgg-default-scheme} to @code{pgp}). If you do want to use
+GnuPG, you can use a compatibility script called @code{gpg-2comp}
+available from
+@uref{http://muppet.faveve.uni-stuttgart.de/~gero/gpg-2comp/}. You
+could also convince your fellow PGP 2.x users to convert to GnuPG.
+@vindex mml-signencrypt-style-alist
+As a final workaround, you can make the sign and encryption work in
+two steps; separately sign, then encrypt a message. If you would like
+to change this behavior you can customize the
+@code{mml-signencrypt-style-alist} variable. For example:
+
+@lisp
+(setq mml-signencrypt-style-alist '(("smime" separate)
+ ("pgp" separate)
+ ("pgpauto" separate)
+ ("pgpmime" separate)))
+@end lisp
+
+This causes to sign and encrypt in two passes, thus generating a
+message that can be understood by PGP version 2.
+
+(Refer to @uref{http://www.gnupg.org/gph/en/pgp2x.html} for more
+information about the problem.)
