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

This is to announce the availability of Version 1.3d of SecureDrive.

SecureDrive Version 1.3d replaces version 1.3a.  A prototype version
1.3b was sent to a few people for testing.  To avoid confusion, I'm
skipping 1.3b for "official" releases.  Similarly, a version 1.3c was
released a short time ago, which did not work with 2M13 as it claimed
to do.

Changes for 1.3d have added minimal new function.  Rather I have
sought to respond to problems brought to my attention. The main
change is to support the 2M13 diskette formatter and some versions
of MSDOS which were incompatible with previous versions of SecureDrive.
See file BUGS13A.DOC for more detail of 1.3d changes.

There is also the addition of an FPART utility designed to help you
locate the physical partition parameters you can use with CRYPTDSK
and LOGIN when use of the DOS disk letter fails.

Releases 1.3, 1.3a, and 1.3d of Secure Drive are based on releases 1.0
and 1.1, mostly written by

  Mike Ingle <mikeingle@delphi.com>

and version 1.2, with significant new code by myself.

The code which we wrote is not copyrighted, but the program contains GNU
Copylefted code, and therefore may be freely distributed under the terms of
the GNU General Public Licence. See file COPYING for legalese.

SecureDrive provides strong encryption via the IDEA cypher (The same
symmetrical cypher used by PGP) for your files on diskettes or up to
four hard disk partitions. You encrypt your diskettes and/or HD
partitions with CRYPTDSK. Then you can access the data by using
LOGIN and SECTSR. This provides "on-the-fly" decryption (and
re-encryption) as disk sectors are accessed by your applications.

Entering LOGIN /C or powering off your PC clears the crypto keys from
memory and your encrypted disks are "instantly" secure.

Mike Ingle and I have different opinions on the distribution of
SecureDrive.  Under the GNU General License (copyleft) I do not need
Mike's permission to distribute version 1.3d and I have not asked for
same.  My policy on distribution is in the version 1.3d doc:

    Exporting this program.  Cryptography is export controlled, and
    sending this program outside the country may be illegal.  Don't do
    it.

    The "author" of versions 1.2 and 1.3, Edgar Swank, says that the
    export ban should not prevent you from placing this program on
    public BBS's and anonymous FTP sites in the US and Canada.  If
    individuals outside the US/Canada use the internet or
    international long distance to obtain copies of the program, THEY
    may be breaking US law.

    Any such foreign individuals should be aware that US law
    enforcement may legally (under US law) apprehend individuals who
    break US laws even if such individuals are not on or even have
    never been on US soil.  Such apprehension may remove such
    individuals directly to US jurisdiction without benefit of
    extradition proceedings in such individuals' home country(ies).
    This has actually happened in at least two cases, Mexico --
    suspect in murder of US drug agent, Panama -- Noriega -- indicted
    in absencia for drug smuggling.  As is well known, after a small
    war with Panama, Noriega was brought to the USA, tried and
    convicted.  He is now a guest of the US Government in a Florida
    prison.

SecureDrive Version 1.3d is already available for download on the
following public BBS's as SECDR13D.ZIP:

  Eagle's Nest         (408)223-9821
  Flying Dutchman      (408)294-3065
  Catacombs BBS        (303)938-9654

It is also available from a mailserver in Texas.  Send mail to

Server@Star.Hou.TX.US
