Okay, that is something different.  I was solely speaking of a tempest
resistant viewer - the kind of thing PGP 6 named "secure viewer(/ing
mode)".

That's right. However these are AFAIK the only versions under the GPL
without restrictions.  The widely used 2.6* versions are under a non
free license diasllowing to change certain parts of the software or to
distribute only parts of it.

In fact there used to be a long discussion whether to keep the
for-your-eyes-only feature in OpenPGP or to drop it.  It does not
belong into the standard as OpenPGP defines a message format and not
an application.

Your quote message got through fine.

Are you sure you used the correct e-mail address (i.e. the e-mail
address you used to subscribe to the list) when you sent the post that
was refused?

Your public key AD24CFB593B61FDD displays 4 different UIDs, none of them
is identical to [EMAIL PROTECTED]

Those two versions, for the Mac, were not pure command line tools. I
have no idea what they did for Windows users.

Version 2.3 of MacPGP was the first PGP port to the Mac. Not really a
Mac application, it worked somehow with a combination of minimalistic
GUI and command line essentials. It was a good starting point for Mac
users who wanted to learn about PGP. I started with that, and I remember
it was nerve-wracking (for me at least).

Version 2.6.3x (maybe it was called FatMacPGP 2.6.3, I am not sure) was
a quantum leap (sort of): it would run on PowerPC and also on 68020 and
68030 CPUs, and behaved like a real Mac application, with many GUI
niceties (or maybe not really a GUI, but some kind of front or shell),
but also with an option to use CLI. There was a feature called something
like "allow viewing by recipient only", but I don't remember whether it
was the secure viewer with TEMPEST resistant fonts, or a warning meant
for the recipient that the decrypted message would not be saved into a
file, and would only be displayed on the recipient's computer display.
The recipient could chose to abide by the warning, or to save the
decrypted message using some specific command or option.

FLOSS = Free Libre Open Source Software.

PGP 2.x.x versions were free software (lower case, meaning free of
payment); Philip R. Zimmermann made PGP available for free (at the
beginning of PGP's career). Whether this qualifies for Free Software
(upper case), I don't know.

The aim of the secure viewer then was to make difficult to obtain eyes-only
message text as a file or a pipe. It checked if output is a live tty,
prevented the plaintext ending on the swap and leaving any temp files.

It was really difficult to get eyes-only message in plain file form with it
in the way (there was no /dev/vcs etc in the days and it needs root anyway).

Software that was distributed under GPL: pgp 2.3 and 2.3a. And pleaase don't
let the discussion slip in legalese tetrapiloctomisation.

My point exactly, excapt that secure viewer needs not to be defined in the
protocol RFC.

Huh, that's new to me.  Both versions are pure command line tools

I am not sure what kind of software you collect untder the term of
FLOSS; if you mean Free Software, PGP has never been Free Software
despite what many people claimed.

Photo IDs are a feature of PGP6 and now OpenPGP.

Some form of secure viewer was present in PGP 2.3 and 2.6 which were FLOSS.

Unless they patented it (sigh) it can be renginered back to the GPG, like
Photo-IDs.

In case swpats gets legalized in EU it won't be possible to write free
tempest resistant viewers. 

The exception are viewers available under a copyleft license (like the
GPL) using the mentioned specific font.
