Recipe 8.3 Encrypted Mail with Pine
8.3.1 Problem
You want to send and
receive encrypted email conveniently with the Pine mailer.
8.3.2 Solution
Use PinePGP.
8.3.3 Description
Before using PinePGP, make sure you have
previously used Pine on your local computer, so you have a
~/.pinerc configuration file. Then download
PinePGP from http://www.megaloman.com/~hany/software/pinepgp,
build, and install it. (As root if you prefer.)When installing PinePGP, you must make a choice: Should messages you
encrypt be decryptable only by their intended recipients, or by
yourself as well? If the former, which is the default behavior, run:
$ pinegpg-install
Alternatively, if you want to change this default, making your
messages decryptable by you (with your public key) in addition to the
recipient, instead invoke:
$ pinegpg-install your@email.address.com
where your@email.address.com is the email
address associated with your intended GnuPG key. [Recipe 7.7]Now let's send an encrypted message to our friend
buddy@example.com , whose GnuPG public key is
already on our keyring. Run pine and compose a
message. Press
ctrl-X
to send the
message normally, and you will receive this prompt, asking if you
want the message filtered before sending:
Send message (unfiltered)?
Press
ctrl-N
repeatedly to display
the filters, which will appear like this:
Send message (filtered thru "gpg-sign")?
Send message (filtered thru "gpg-encrypt")?
Send message (filtered thru "gpg-sign+encrypt")?
Select the filter you want and press Return to send the message. If
you're signing the message, you'll
be prompted for your key passphrase first.That's sending, but what about receiving? When an
encrypted message arrives in your mailbox and you attempt to view it,
pine will automatically prompt for your
passphrase. If entered correctly, the message will be displayed. The
beginning and end of the decrypted text will be surrounded by
[PinePGP] markers:
Date: Tue, 22 Oct 2002 21:08:32 -0400 (EDT)
From: Some Buddy <buddy@example.com>
To: You <smith@example.com>
Subject: Test message
--[PinePGP]--------------------------------------------------[begin]--
Hey, d00d, this encryption stuff rocks!
--[PinePGP]-----------------------------------------------------------
gpg: encrypted with 1024-bit ELG-E key, ID 61E9334C, created 2001-02-21
"Some W. Buddy (The d00d) <buddy@example.com>"
--[PinePGP]----------------------------------------------------[end]--
How does this all work? PinePGP filters your sent and displayed email
via the
sending-filters
and
display-filters variables in
~/.pinerc.
