==========================================================================
                     F-Secure Desktop 1.0 Beta 
==========================================================================

F-Secure Desktop Beta is subject to the terms detailed in the Beta license 
agreement accompanying it. 

Data Fellows has just made a major breakthrough in optimizing the Blowfish 
encryption algorithm. We have achieved 12-18Mbits per second encryption 
speeds in laboratory conditions. 

The release version of F-Secure Desktop will use an optimized version of 
Blowfish, that will beta about 3-4 times faster that the non-optimized 
version in the Internet beta.

                  Protecting Your Information Assets
==========================================================================

  How are your company information assets protected?

Today's technology makes it possible to store a copy of your company's 
sales database on every sales persons laptop. The copy contains the same 
confidential data as the actual company database that is protected by 
firewalls and locked cabinets. What about the copy on the laptop? Isn't it 
entitled to the same level of protection, or even more as it travels in a 
more vulnerable environment? All previously closed sales, quotes, and 
pending cases that your competition would kill to see are unprotected.

  Introducing F-Secure Desktop for Windows and Windows 95

There are many access control and security packages on the market, but 
none of them is easy enough to use that your people would trust it and 
install it on their computers. F-Secure Desktop removes the complexity and 
provides an easy-to-use, easy-to-install, low-cost, strong-encryption 
solution to protect your company's information assets. With F-Secure
Desktop, you can encrypt/decrypt files, directories, and Windows 95
folders automatically during the starting and closing of Windows. F-Secure
is by far the easiest, and strongest way to protect the sensitive
information on your laptops and PCs.

F-Secure Desktop is an add-on for your Windows File Manager, providing you
a user-interface that you already know how to use. The only change you'll 
notice is three added buttons on the tool bar and a new "F-Secure" menu.

On your Windows 95, F-Secure Desktop is integrated to the Windows 95 shell. 
You can drag and drop files to folders that will be encrypted
automatically or you can encrypt/decrypt any object by just clicking the
right mouse button on the object and selecting encrypt or decrypt. Nothing
could be more simpler to use.

With the AutoSecure(TM) feature, you can define sets of files,
directories, and Windows 95 folders that will be automatically encrypted
and decrypted every time you start or close Windows. You can leave top-
secret files out of the AutoSecure(TM) list, to be manual encrypted. 
F-Secure Desktop does not make any special files or directories on your
system. You select which files, directories, and folders are encrypted,
quickly and easily, anywhere. This means that you do not have to make any
changes to your system structure when adding F-Secure Desktop strong
encryption technology to your PC or laptop.

  Easy to Use, Easy to Setup

F-Secure Desktop comes with a setup Wizard that is used to create your
keys, select the files to encrypt, backup your master key, and to setup
other options in F-Secure Desktop. We have made F-Secure Desktop so simple
to setup and use that you'll never have to go back to the settings after
you have finished the setup.

Each user can choose to select an existing key that has been created to be 
used by a group of people sharing private data, or to create a personal 
key that will keep their data private.

NOTE: For more information on the products features, see "Release Notes".

Below is a list of common tasks and how to perform them.

HOW TO ENCRYPT OR DECRYPT A FILE
================================
Windows 3.1
-----------
Start File Manager, browse for the file you want to encrypt, then select 
F-Secure|Encrypt... from the menu.

Next you have to select the way you wish to decrypt the file in the 
future:
 a) Checking "Add to AutoSecure Files" will decrypt the file always 
    when starting Windows.
 b) Leaving "Add to AutoSecure Files" unselected will leave the file
    encrypted until you manually decrypt it.
Then type in your passphrase and click OK to encrypt the file.

To decrypt a file with an .FFF extension, double click the file and 
type in your passphrase and click OK to decrypt the file. 

NOTE: All decrypted files will be automatically encrypted when you 
close Windows!

Windows 95
----------
Select a file, directory, or a folder with the Windows Explorer. 
Click the right mouse button on your selection to see a menu, select
Encrypt...

Next have to select the way you wish to decrypt the file in the future:
 a) Checking "Add to AutoSecure Files" will decrypt the file always 
    when starting Windows.
 b) Leaving "Add to AutoSecure Files" unselected will leave the file
    encrypted until you manually decrypt it.
Then type in your passphrase and click OK to encrypt the file.

To decrypt a file with an .FFF extension, double click the file and 
type in your passphrase and click OK to decrypt the file. 

NOTE: All decrypted files will be automatically encrypted when you 
close Windows!

HOW TO ENCRYPT OR DECRYPT FILES QUICKLY
=======================================
To encrypt all decrypted files, open the F-Secure Desktop group from the
file manager or from the Windows 95 Programs Menu. Next double click the
"Encrypt All Files" icon, type in your passphrase and click OK to 
encrypt the files.

To decrypt all AutoSecure files, open the F-Secure Desktop group
from the file manager or from the Windows 95 Programs Menu. Next double
click the "Decrypt All Files" icon, type in your passphrase and click OK
to decrypt the files.

NOTE: All decrypted files will be automatically encrypted when you 
close Windows!

HOW TO ADD OR REMOVE FILES FROM THE AUTOSECURE(TM) FILES
========================================================
You can access the AutoSecure(TM) dialog easily from the control panel.
Open the F-Secure control panel application, select AutoSecure and view,
add, or remove file, directories, and folders as you wish.

HOW TO CHANGE YOUR PASSPHRASE
=============================
We recommend that you select a passphrase rather than a password to be 
used with F-Secure Desktop. The passphrase will be used to protect your 
encryption key.

A normal password would be something like "qw79lp0", a passphrase is 
something a bit longer like "this is something for me to remember!".
Well selected passphrases are almost impossible to break.

To change your passphrase the F-Secure Desktop control panel application,
select "Passphrase" and type in the requested information. You can change 
your passphrase as often as you like, and still be able to access all 
your encrypted files.

NOTE: Your passphrase is the weakest link in this product, so select it 
with care!

HOW TO USE A COMMON WORKGROUP KEY TO SHARE INFORMATION
======================================================
A workgroup key is just an ordinary encryption key created with the 
F-Secure Desktop Wizard. Take the backup disk for the key that you are 
using and distribute it to those personnel that you want to share 
information with. Ask them to install that key when they set up their
copy of F-Secure Desktop. This way you can share encrypted files with 
each other.

==========================================================================
                           Known Issues & Bugs
==========================================================================

Known Issues
 o Help for the application is not available yet.
 o If the uninstallation fails you should:
   - Boot to DOS
   - Delete the following files in your \WINDOWS\SYSTEM directory: 
     FSID32.DLL, FSCOM32.DLL, FSECSE.DLL, FSEC32.CPL, and FSDENU32.DLL
   - Remove the reference to FSID32.DLL in the [Boot] section in SYSTEM.INI
   - Restart the computer and boot to Windows 95.
 o The encryption algorithm is an unoptimized version of Blowfish. The 
   optimized version is 3-4 times as fast as the current implementation.
