This directory contains a tutorial illustrating Enigma
Logic's "SafeWord PC LAN-Safe" software for IBM PC's, XT's,
PS/2's and compatibles running MSDOS, DRDOS, PCDOS and/or
Windows. It implements an encrypting file system that is
compatible with both local drives and network file servers.

File-by-file or directory-by-directory encryption can be
asserted within each workstation, so that sensitive information
can be kept secure both on mass storage and as it traverses
networks.

This tutorial includes an animated illustration of the internal
workings of typical broadcast-based LANs, focusing on the
security problems that result from broadcasting everything
to everybody.

A demonstration copy of SafeWord PC LAN-Safe software is also
available from our anonymous ftp site. For those of you that
don't already know about this, just ftp to:

ftp.netcom.com

Then cd to:

/pub/bbosen/Enigma

and have a look around, paying special attention to the various
"read.me" files. The PC Lan-Safe demo software is in this
directory:

/pub/bbosen/Enigma/PC-LanSafe

Get all of the files there after examining the read.me file to
make sure you are getting what you think you are getting. Note
that this demonstration copy is severely restricted in terms of
the strength of the cryptoalgorithm being used; we wouldn't want
any of you playing with _real_ encryption without government
authorization, would we?.........

Also: if you get the demonstration software from /pub/bbosen/Enigma/
PC-LanSafe, then there will be _no_ point in getting this tutorial
from /pub/bbosen/Enigma/Tutorials/VGA/Grasp/PC-LanSafe, as the
demonstration software _also_ includes the tutorial!

Enjoy!
