Re: Question about the MacPGP

re Tai's item about more user-friendly decryption on the Mac version....

Seems to me we need it for encryption as well...  For instance, telecom
software which allows you to back out into a screen editor where you write
something and then encrypt it, and then get back to telecom and transmit the
ciphertext directly.  In my use of email, spontaneous mail and replies are
vital.  Having to go offline, go into WP, compose, go to crypto and encrypt,
then go back to telecom, link up again, and transmit.... Holy cow, if that
were a prescription for safe sex, it would be "Start a romantic evening.
Just when you and your Love are sitting by the fire holding hands, get in
the car, go to the drugstore and buy condoms.  Then come back to where
you've left your Love waiting by the fireplace, and try to get back in the
romantic mood.  Then before bedtime, walk around the house to make sure all
the lights are off and the oven is off and the dog is in and the cat is out.
Then retire for the night, and try to get the romantic mood going again,
hoping that your Love hasn't fallen asleep while you were making your
rounds..."  Eee-yow, we can do better than that!

The following would require customization on both ends, but seems doable:

You compose the message, using emacs or some other Turing-complete editor.
You hit the "PGPify" key [sequence].
emacs echoes a special START string
The local comm program recognizes it and goes into "capture" mode.
emacs blats the plaintext to stdout, where it is captured.
emacs echoes a STOP string.
The comm program sees this, stops capturing, shells to DOS, and runs PGP.
emacs kills the original text block.
(emacs command ends)
The comm program shoves the cyphertext into the upload stream.
(comm macro reverts to lurk mode)
You send the message.

All of this, I think, could be implemented with available programs.
Kermit won't hack it on the local end, so maybe I'll switch to
Telemate.  This protocol would require a clean line or EC modem; is
this a problem?

It might be a better move to write a [shell, Perl] script that's a
drop-in replacement for Unix pgp: it goes through the whole protocol
above, and looks to the outside world as if it had done the work
itself.  People have written emacs macros (I think) to make this
work with mail; it could also be used as a unix-pgp replacement in
other places.

It might be nice if the plaintext were not echoed to the screen while
being transferred, too.

This is where my little Crypto-Dongle would help.  To encrypt, just
flip a switch and type.  

Same thing for decryption... flip a switch and everything received is
decrypted...
