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.

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]
