7.6.1. PGP Versions and Implementations
- 2.6ui is the version compatible with 2.3
+ What is the difference between versions 2.6 and 2.6ui?
- "PGP 2.6 is distributed from MIT and is legally available
to US and Canadian residents. It uses the RSAREF library.
It has code that will prevent interoperation with earlier
versions of PGP.
"PGP 2.6ui is a modified version of PGP 2.3a which
functions almost identically to MIT PGP 2.6, without the
"cripple code" of MIT PGP 2.6. It is legally available
outside the US and Canada only." [Rat
<ratinox@ccs.neu.edu>, alt.security.pgp, 1994-07-03]
+ DOS
- Versions
+ Pretty Good Shell
- "When your Microsoft Mail supports an external Editor,
you might want to try PGS (Pretty Good Shell),
available as PGS099B.ZIP at several ftp sites. It
enables you to run PGP from a shell, with a easy way to
edit/encrypt files." [HHM LIMPENS, 1994-07-01]
- Windows
+ Sun
- "I guess that you should be able to use PGPsendmail,
available at ftp.atnf.csiro.au:/pub/people/rgooch'
[eric@terra.hacktic.nl (Eric Veldhuyzen), PGP support for
Sun's Mailtool?, alt.security.pgp, 1994-06-29]
+ Mark Grant <mark@unicorn.com> has been working on a tool
to replace Sun's mailtool. "Privtool ("Privacy Tool") is
intended to be a PGP-aware replacement for the standard
Sun Workstation mailtool program, with a similar user
interface and automagick support for PGP-signing and PGP-
encryption." [MG, 1994-07-03]
- "At the moment, the Beta release is available from
ftp.c2.org in /pub/privtool as privtool-0.80.tar.Z, and
I've attached the README.1ST file so that you can check
out the features and bugs before you download it. ....
Currently the program requires the Xview toolkit to
build, and has only been compiled on SunOS 4.1 and
Solaris 2.1."
+ MacPGP
- 2.6ui: reports of problems, bombs (remove Preferencs set
by previous versions from System folder)
- "MacPGP 2.6ui is fully compatible with MIT's MacPGP 2.6,
but offers several advantages, a chief one being that
MacPGP 2.6ui is controllable via AppleScript. This is a
very powerful feature, and pre-written AppleScripts are
already available. A set of AppleScripts called the
Interim Macintosh PGP Interface (IMPI) support
encryption, decryption, and signing of files via drag-n-
drop, finder selection, the clipboard, all accessible
from a system-wide menu. Eudora AppleScripts also exist
to interface MacPGP with the mail program Eudora.

7.6.2. What versions of PGP exist?
- PGP 2.7 is ViaCrypt's commercial version of PGP 2.6
7.6.3. PGP 2.6 issues
- There has been much confusion, in the press and in
discussion groups, about the issues surrounding 2.5, 2.6,
2.6ui, and various versions of these. Motivations,
conspiracies, etc., have all been discussed. I'm not
involved as others on our list are, so I'm often confused
too.
+ Here are some comments by Phil Zimmermann, in response to a
misleading press report:
- "PGP 2.6 will always be able to read messages,
signatures, and keys from olderversions, even after
September 1st. The older versions will not be able to
read messages, signatures and keys produced by PGP 2.6
after September 1st. This is an entirely different
situation. There is every reason for people to switch to
PGP 2.6, because it will be able to handle both data
formats, while the older versions will not. Until
September, the new PGP will continue to produce the old
format that can be read by older versions, but will start
producing the new format after that date. This delay
allows time for everyone to obtain the new version of
PGP, so that they will not be affected by the change.
Key servers will still be able to carry the keys made in
the old format, because PGP 2.6 will still read them with
no problems. " [Phil Zimmermann, 1994-07-07, also posted
to Usenet groups] [all dates here refer to 1994]
- "I developed PGP 2.6 to be released by MIT, and I think
this new
arrangement is a breakthrough in the legal status of PGP,
of benefit to
all PGP users. I urge all PGP users to switch to PGP
2.6, and abandon
earlier versions. The widespread replacement of the old
versions with
this new version of PGP fits in with future plans for the
creation of a
PGP standard." [Phil Zimmermann, 1994-07-07, also posted
to Usenet groups]
7.6.4. PGP version 2.6.1
- "MIT will be releasing Pretty Good Privacy (PGP) version
2.6.1 real soon now. By tomorrow, I think. The MSDOS
release filename will be pgp261.zip, and the source code
will be in pgp261s.zip. The MIT FTP site is net-
dist@mit.edu, in the pub/PGP directory." [corrected by
Derek Atkins to be: net-dist.mit.edu, not net-
dist@mit.edu.]
"This new version has a lot of bug fixes over version 2.6.
I hope this is the final release of this family of PGP
source code. We've been working on an entirely new version
of PGP, rewritten from scratch, which is much cleaner and
faster, and better suited for the future enhancements we
have planned. All PGP development efforts will be
redirected toward this new code base, after this 2.6.1
release." [Phil Zimmermann, Cypherpunks list, 1994-09-02]
