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

This is to announce the availability of Version 1.4 of SecureDrive.

SecureDrive Version 1.4 replaces version 1.3d and previous versions.

Changes for 1.4 have added significant new function.

New features include ability to use a keyfile either instead of or
in addition to a passphrase, the /ADD function and the option to
specify a drive letter, which is remembered, when specifying manual
partition parameters to LOGIN.

/ADD allows you to LOGIN multiple hard disk partitions (with the
same key) at the same time.

The subroutine which "finds" a physical hard disk partition based on
the DOS drive letter has been improved, so hopefully situations where
manual partition parameters must be used will be rare.

Releases 1.3, 1.3a, 1.3d and 1.4 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 1.4 and I have not asked for
same.  My policy on distribution is in the version 1.4 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).

SecureDrive Version 1.4 is already available for download on the
following public BBS's as SECDR14.ZIP:

for the executable files.  Finally here is my public key, also
