Subject: Announce PGP263UI (long message)

-----BEGIN PGP SIGNED MESSAGE-----

To All PGP Users:

I am happy to announce the availability of PGP 2.63ui, the successor
to PGP 2.6ui and 2.62ui, an unofficial international release of the
famous public key encryption program, based originally on version
2.3a.

This version is being made available for a number of reasons:

* It is the only version fully compatible with *all* versions of PGP
from 2.0 to 2.7

* It incorporates a number of bug fixes and features not available
in the MIT release (see below) or in Stale Schumaker's 2.6.x.i
releases based on the MIT release.

* This version, like 2.3a and 2.6xui before it, is published under the
terms of the GPL. Consequently:

  - You are not bound by the RSADSI licence since this version does not
  use RSAREF (which forbids commercial use and unauthorised use of the
  cryptograpgic routines), as you are with MIT PGP

  - You are not bound by the MIT licence (which requires the program
  to produce output that cannot be read by earlier versions), as you are
  with both MIT PGP and Staale Schumacher's PGP 2.6.xi.

  - you can therefore do what you like with the code of the program
  provided any derivative work is also GPL'd.

  - The only relevant patent for users outside the USA is Ascom-Tech's
  patent on IDEA. For non-commercial use it's free, anywhere. For
  commercial use you need  a license, but Ascom-Tech offers a single-
  user license for a modest fee. See

    http://www.ascom.ch/systec

Users inside the USA may not legally use 2.63ui, because the RSA
patent is in effect there. USA residents are advised to obtain one
of the MIT versions which have a license for non-commercial use of
RSA.

However, I note in passing that by using the armor_version parameter
in CONFIG.TXT, that armored output from PGP 2.63ui can be made
difficult or impossible to distinguish from other versions.

Note that I personally have not done very much of the actual coding on
this version.  However if bugs are reported or constructive
suggestions for improvements made I will pass them on to the
individual(s) who have done the bulk of the work to make this release
possible.  I am assured that continuing support will be provided.

This is a partial list of the changes and fixes since 2.62ui.
A complete list is in file 263UICHG.ASC, which is inside both
ZIP distribution files.

Added CONFIG.TXT Parameters:

LabelEncrypt = on     # Label Encrypted Armored files with Recipient(s)

This will add readable text in front of an encrypted and armored file
listing the public keys used to encrypt it.  The format of the text is
similar to what appears on the console during (-l) decryption.

PrePendSigV=on      # Prepend Signature Verification msg to output text

When verifying the signature on a text (not binary) file, and a
detached signature (-b) is not requested, PGP 2.63ui will prepend a
message with the results of the signature verification (good or bad)
similar to what appears on the console.

Expanded Compatibility with Early PGP Versions.

version_byte=3 is usually set to Emulate PGP 2.6 after 9/1/94

Version_byte must be set to 2 before encrypting/signing
messages to be decrypted/verified by PGP 2.2 or 2.3a.

Also, unique to PGP 2.63ui, is the ability to set version_byte to 2
in extracted keys (-kx[a]).  This allows PGP 2.63ui to extract keys
which may have been created and/or signed by MIT PGP or by a ui
version with version_byte set to 3 and create an extracted key which
may be added (-ka) by PGP 2.3a.

Note that the reverse is not true. If version_byte=3, keys created
with version_byte=2 are -not- changed when extracted.

Expanded Error Checking

Most disk writes are now checked for errors or running out of disk
space.

Key Generation and other Keyring maintenance operations check for
write access to public and (where required) secret keyrings before
lengthy processing starts.  Previous versions were not checking if the
keyrings were set to read-only, which led to invalid results.

PGP 2.63ui allows you to change UserID's of keys not your own
(corresponding secret key not present).  You can sign the new ID
with your own secret key but (obviously) not with the other person's
secret key.

PGP 2.63ui is distributed in two ZIP files

   pg263ui.zip   [executables & documentation]
   pg263uis.zip  [source code & documentation]

They are currently available at:

ftp://ftp.funet.fi/pub/mirrors/utopia.hacktic.nl/pgp/pc/dos/

ftp://utopia.hacktic.nl/pub/replay/pub/pgp/pc/dos/

Each zip file contains a MANIFEST signed by me which gives the MD5
digests of all other files within the ZIP. You can use the MD5SUM.EXE
program included in pg263ui.zip to verify the MANIFEST (after using
PGP to strip the signature).
