By default, Mailcrypt assumes you are using one of the PGP 2.6.x
versions. This permits backward compatibility for the millions of
satisfied users of Mailcrypt 3.4 worldwide. If you wish to specify a
different version of PGP, use this function. Its action is the same as
setting the variable mc-default-scheme
. For a list of supported
versions, press the tab key. "2.6" means 2.6.x, the original (and default).
"5.0" is pgp 5.0. "gpg" is GnuPG.
Mailcrypt works by providing two minor modes for interfacing with
cryptographic functions: mc-read-mode
and mc-write-mode
.
mc-read-mode
provides key bindings for processing messages which
you have received; mc-write-mode
provides key bindings for
processing messages which you are about to send. These minor modes will
indicate when they are active by placing a characteristic string in the
mode line (see Mode Line). They will also add a Mailcrypt
pull-down menu to the menu bar.
The normal installation procedure (see Installation) will arrange
for the appropriate mode to be active when you read and compose mail and
news. But you may want to use Mailcrypt's functions at other times; to
do so, you can call mc-install-read-mode
or
mc-install-write-mode
directly. For example, if you were editing
a file in Text mode and wanted to digitally sign it, you would type
M-x mc-install-write-mode, then C-c / s (see Signing).
Once one of the Mailcrypt modes is active, you can get a summary of the
available functions by typing C-h m or by examining the
Mailcrypt
pull-down menu.
The description of each function below includes which of the modes has a binding for that function.
