-----BEGIN PGP SIGNED MESSAGE-----
This is to announce the availability of Version 1.2 of SecureDrive.
This release of Secure Drive is based on release 1.0, mostly
written by
Mike Ingle <[email protected]>
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.
Version 1.2 adds significant new function.
As of Version 1.2, you may use an operand /PGP with LOGIN, either
by itself, or with other operands. By itself,
LOGIN /PGP
will prompt for a passphrase and set the PGPPASS environment variable with
whatever is entered. If PGPPASS is already set then
LOGIN D: /PGP
or
LOGIN /F /PGP
will use whatever PGPPASS is set to as the passphrase. For the hard
disk partition, LOGIN will test the PGPPASS passphrase. If it is incorrect,
then it will prompt you for another passphrase.
If PGPPASS is NOT set when these forms of LOGIN are used, than a passphrase
is prompted for AND PGPPASS is set to this passphrase. This is more
secure than using the SET command since LOGIN only echoes "*"'s when
entering the passphrase.
As of Version 1.2, typing LOGIN /C /PGP will clear the SecureDrive crypto
keys from memory AND clear the PGPPASS environment variable. This is done
in a manner less likely to leave your passphrase in memory than just using
the DOS SET command. In addition, Version 1.2 clears all the free memory
it can find, which is likely to include some plaintext. However, if you
want to be absolutely sure all traces of sensitive data are erased from
memory then turning off the computer is still recommended.
As of version 1.2, if PGPPASS is set before you run CRYPTDSK, CRYPTDSK
will ask to use the value of PGPPASS for the passphrase before
prompting you (for encryption), or try PGPPASS (for decryption).
Obviously, if you encrypt or decrypt a lot of diskettes at once, this
feature can save you a lot of typing.
The purpose of these changes is to allow you to enter a single passphrase
only once per boot IF you choose to use the same passphrase for your PGP
secret key, your SecureDrive encrypted hard disk partition, and SecureDrive
encrypted floppies.
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 1.2 and I have not asked for
same. My policy on distribution is in the version 1.2 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 version 1.2, 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 1.2 is already available for download on the
following public BBS's as SECDRV12.ZIP:
Eagle's Nest (408)223-9821
Flying Dutchman (408)294-3065
I will send a copy via E-mail to any person with a US/Canada net
address who requests a copy and will upload it to a public BBS or
anonymous FTP site. (I don't have access to FTP from my account here).
