Information about “EZ-CRYPT-LITE”
If file privacy and security is a priority, EZ-CRYPT-LITE is a powerful
encryption/decryption package that anyone can use. EZ-CRYPT-LITE will
encrypt a source file using any one of several methods, and only decrypt
the file using a confidential key. And do it all without cryptic
commands!
Ideal for use with electronic information services and almost any type
of file transfer (both electronic and mail service). Extensive menus,
on-line manual, and context-sensitive help make it easy to use. And if
you want file statistics to determine how well your file is encrypted
(frequency/distribution, mode, mean, median, and more) they are
available from within EZ-CRYPT-LITE. There is even a "file wipe"
option to completely erase all traces of your file after deletion.

WHAT IS EZ-CRYPT LITE?
======================
EZ-Crypt Lite is a powerful encryption/decryption package that
allows you to:
1. Encrypt a source file using one of several methods,
2. Decrypt the file using a confidental key,
3. Obtain file statistics (frequency/distribution, mode, mean,
median, and more) to determine how well the file is encrypted
(also to look at other encrypted files),
4. And do it all without cryptic commands!
EZ-Crypt Lite comes configured to work with most display adapters
and monitors. You can easily customize it to suit your needs.
HARDWARE REQUIREMENTS
=====================
1. IBM PC/XT/AT, IBM PS/2, or fully compatible computer.
2. 384K RAM and DOS 3.0 or later.
3. Any monitor. EZ-Crypt Lite has been written to accommodate
monochrome, color, enhanced graphics, and video graphics array
adapters. Some "autoswitch" adapters may need to be in "manual".
4. At least one 5.25" floppy disk drive. Two floppy disk drives
or one floppy and a hard disk (300K free space minimum for the
full system) are strongly recommended.
5
INSTALLATION
============
Two 5.25" diskettes are normally included with EZ-Crypt Lite.
Also, some copies sold thru various distributors may vary in disk
quantity and make up, but all the files will be there.
The diskette with the bright green label contains a Valueware
version of EZ-Crypt Lite that has additional information screens,
but all features are enabled. The purpose of this diskette is to
check your entire system for proper operation before you break
the seal on the full system diskettes. (a.k.a. Diskette #0)
Diskette #1 (the main disk) contains the actual program, the
context sensitive help, the on-line manual and additional support
files. Diskette 1 is sealed.
INSTALLATION FOR the Valueware DISKETTE
=======================================
1. Make sure the Disk Operating System (DOS) has been loaded into
your system and you are at A>> (system prompt). If you are
confused, consult your computer manual or your local PC "guru"
first as we can only help you with EZCRL. If you need help with
DOS, try a local community college, adult continuing education
course at a local high school, or a "Puter-Tutor" type training
service.
2. Insert the Valueware diskette into DRIVE A.
3. Type
EZCRL
and press
RETURN (ENTER on some machines, also, <<cr>> )
The opening screen of EZ-Crypt Lite will ask you to press any key
to continue. Pressing any key will allow you to scroll through
various opening screens with important information (these screens
may not be included). When the EZ-Crypt Lite's Main Menu appears
on your screen, go to the "GETTING STARTED" section of the manual
(this section is just after this installation section). Follow
the easy to understand instructions and welcome to the world of
EZ-Crypt Lite!
Some packaging may not contain the "Valueware" diskette, so just
ignore this section of the manual if you do not have one. Reasons
include site licensing and/or other distributor arrangements.
P.S. The Valueware version of EZ-Crypt Lite will do everything;
however, help may be limited due to space limitations. Also
additional product information screens may be added.
6
Feel free to share ONLY the Valueware version with friends and
potential users of EZ-Crypt Lite for evaluation purposes only.
You may not use the Valueware version on other machines in order
to avoid purchasing additional copies of the full program. You
may not give away any copies or make more than one copy of the
fully operational program for other than archival purposes. The
full version of EZ-Crypt Lite has a unique serial number embedded
in each copy for traceability.
INSTALLATION FOR FLOPPY DRIVE SYSTEMS (NO HARD DRIVE)
=====================================================
Please read through the entire installation procedure before
proceeding. This may save you some frustration later.
1. Make sure Disk Operating System (DOS) has been loaded into
your system and you are at A:> system prompt. If you need help,
consult your DOS manual or find a local computer "guru" to help
you out.
2. Make a backup copy of the diskettes. ONLY operate from backup
copies!
3. Insert diskette #1 into DRIVE A. No additional steps are
needed.
Please sign and mail your registration card to the address on it.
Make a copy for your own records. User support and updates
cannot be provided UNTIL your registration form is on file.
Although EZCRL is not copy protected, you may make copies for
archive purposes only. The purchase of one copy does not
authorize you to install EZCRL on more than one machine or on a
network. If you intend to install to a hard drive, but run the
program from your floppy drive first, delete the file EZCRL.CNF
(if it exists) before loading to your hard drive.
INSTALLATION FOR HARD DISK SYSTEMS
==================================
1. Make sure DOS has been loaded into your system and you are at
C:>. (Note: Installation on a hard disk will require a minimum
of 300K of free disk space for the full system.)
2. Create a subdirectory called "EZCRL". If you are not
familiar with creating a subdirectory, simply type
MD C:\EZCRL followed by Return
If your drive is other than C:, substitute the appropriate
letter.
7
3. Place diskette #1 (bright red label) into DRIVE A and type
COPY A:*.* C:\EZCRL followed by Return
The program, on-line manual, and other related files on diskette
#1 will now be copied to your hard disk.
8. At C:> type
CD \EZCRL followed by Return
This will put you in the EZCRL subdirectory.
9. Type
EZCRL followed by Return.
Admire the glittering opening screen, press any key to continue,
and select one of the menu options on your screen.
IMPORTANT INSTALLATION NOTES:
1. Diskette #1 contain many files in addition to EZCRL.EXE.
Because EZ-Crypt Lite is a large program, the additional files
EZCRLHLP.TXT and EZCRLHLP.INX are required for context sensitive
help. EZCRLMAN.TXT and EZCRLMAN.INX are required for the on-line
manual. So please make sure that these files are in your default
directory when running the program.
If you have only one floppy drive, you can build a work diskette
containing: EZCRL.EXE, EZCRLHLP.TXT, EZCRLHLP.INX, EZCRLMAN.TXT,
and EZCRLMAN.INX. Do not copy EZCRL.CNF, if it exists. A new
EZCRL.CNF will be saved when you select options.
2. If your EZ-Crypt Lite does not run properly:
A. Delete the EZCRL.CNF file and try to run again. Check out our
troubleshooting section near the end of this manual.
B. Your machine may not be totally IBM PC operating system
compatible. This is not always disastrous and a quick call to
our phone support staff may solve your problem.
C. You may have a slightly incompatible "EGA" card with auto
switch features. Usually, turning off autoswitch and forcing the
system into the EGA mode solves the problem.
D. If you have any memory resident programs or system drivers,
try running without them loaded in your computer. On some
computers, ANSI.SYS is suspect.
8
3. If your monitor appears to be losing certain characters or
features, you may have a "color" system with a composite
monochrome (green, amber, LCD, etc.) monitor. Adjust the
contrast and brightness of the monitor until the screen is
readable. In some cases, you may have to go to the Install Menu
to chose acceptable "colors". See the "Troubleshooting" section.
4. This Manual is designed to give you a general overview and
familiarity with the program. More complete, up-to-date
information is available to you through the context sensitive
help (F1) and the on-line manual. When using the more advanced
features of the program, the help screens will guide you through
the toughest questions with ease. As EZ-Crypt Lite continues to
add more features, you can be sure that the on-line manual and
context sensitive help will give you the guidance needed. This
way everybody wins. We don't spend money continually revising
manuals and charging you higher prices, and you get what you want
and deserve: accurate up-to-date information. So fire up the
computer, dig in, and welcome to EZ-Crypt Lite!
5. Note to advanced users: To be able to run EZCRL from any point
on your hard disk, create a batch file called EZCRL.BAT and store
it in your path.
It should contain --> C:\EZCRL\EZCRL.EXE C:\EZCRL\EZCRL.CNF
This will enable you to run EZCRL from anywhere on your hard disk
with full context sensitive help and on-line manual. Be sure to
install the help/manual path within EZCRL to be C:\EZCRL.
9
GETTING STARTED
===============
After you type EZCRL <<cr>> (Enter or Return), the opening screen
of EZ-Crypt Lite (EZCRL) will appear. At the bottom of your EZCRL
opening screen you are instructed to press any key to continue.
The MAIN MENU will appear on your screen.
The Main Menu options with descriptions are below.
On-Line Manual: This is an on-line manual covering features of
EZ-Crypt Lite in more depth than the documentation available in
this manual.
Encrypt: Encode or hide the information within a file to make it
unreadable to anyone who doesn't have a special access code
called a key. Just like you can't unlock a lock without a key,
you can't look at an encrypted file without the key. You limit
the number of people who know the key, thereby limiting the
number of people who can access the intelligence within the file
even if they have access to the file. A key is simply a
combination of letters and numbers. They may or may not have any
conventional meaning. For example, the letters xyz12345 could be
a key.
Please note that we provide several methods of encryption and
decryption. The methods are listed roughly in order of the level
of protection they provide for your data. The more powerful the
method, the further down in the methods list it is. EZ-Crypt
doesn't store the encryption method or the key you used to
encrypt the file. If you forget this information for the
decryption process you can also forget your file. This is the
nature of data protection.
Decrypt: Decryption is the opposite of encryption. You use a key
with the encrypted file to reverse the encryption process giving
you the file you started with.
Analysis/Statistics: Here you can "look" at any file to see how
the characters are distributed within the file. Statistics are
provided to allow you to get a feel for the "goodness" of the
encryption process.
Install: The installation portion of EZ-Crypt Lite allows you to
customize the colors, directory defaults, and other options.
Quit and exit to DOS: All good things must come to an end.
Choose this option if you want to leave EZ-Crypt Lite and return
to DOS.
You may choose any of the displayed options by pressing the first
letter or by moving the light bar (the giant cursor) with your
cursor keys or space bar to the desired option and pressing
Return. Please note that once you have a pulldown active, the
first letter selects options within the pulldown NOT the top EZ-
10
Crypt Lite main menu line.
(If you have a "color" system with a composite monochrome monitor
and don't see a light bar or other features, try adjusting the
brightness or contrast of your monitor. You may also need to
install special colors for your system. See the Install Menu.)
Now let's do something simple to demonstrate how EZ-Crypt Lite
works.
Press E (Encrypt)
Then press enter with the "pick from a menu" option highlighted.
Your screen should clear and you will be given a list of files to
encrypt. Press enter with the first file highlighted. Press
enter again on the next menu to accept the default name for the
encrypted file.
You have just encrypted your first file.
TUTORIAL (encrypting/decrypting a file)
=======================================
Now let's encrypt a file while using various options. Don't
worry about being fancy or being intimidated; this first use is
only for practice. We can get fancy later.
From the Main Menu, highlight the encrypt section and press
E
(Encrypt) a file.
The encrypt pulldown will appear on the menu with the SelectMenu
option highlighted. Steps are:
1. Press enter. You will now be prompted for where the file is
located which is to be encrypted. You are being asked for the
subdirectory name for its storage location.
2. Press enter to accept the default directory. A directory of
files will appear with the first filename highlighted.
3. Press enter to use this file. You will then see a window
listing multiple options for encryption method, key, and output
file. Accept all the defaults by pressing enter. Note:
Pressing enter on the destination filename is the signal that you
are done editing the options.
4. A file will now be written in encrypted form using the
default key (probably Unknown) and the default filename show.
The file to be encrypted is broken into small blocks which can be
easily handled and then encrypted. You will see the block number
increase as each block is processed. Press any key to return to
11
the main menu after it finishes.
From the Main Menu, highlight the decrypt section and press
D
(Decrypt) a file.
To decrypt a file you reverse the process for encrypting a file.
You first select the file you just encrypted using the same steps
as for encryption. Don't change the encryption method or key!
Specify a output file name as appropriate. It's that simple.
12
ADDITIONAL FEATURES
===================
COLOR CONTROL
For users with color monitors, the color option in the Install
menu gives you total color control of text, background, borders,
highlighted areas, etc. Just press C from the install menu.
Troubleshooting
===============
Displays
If, after loading EZ-Crypt Lite, you see text and no borders, or
nothing at all, you may have a compatibility problem. EZCRL uses
high speed screen updates which may cause a problem with some
not-too-close IBM PC operating system compatibles. For example,
the Tandy 2000 and Sanyo 555 series computers are not compatible
with EZCRL.
IBM type monochrome (MDA), color (CGA), EGA (enhanced graphic),
and VGA (video graphics array) adapters are known to work with
EZ-Crypt Lite. If you are using a compatible color video card
with a green or amber screen, or LCD monitor, you may need to
adjust your brightness and contrast, or Install other "colors"
from the color installation screen. Also see the BWVIDEO.DOC
file. BWVIDEO.COM is a "color killer" that works especially well
with composite monochrome monitors, and lap top computers with
LCD monitors. Sometimes executing the DOS "MODE BW80" command
works.
Some "autoswitch" Enhanced Graphic Adapters and "Hercules" type
mono-graphics cards may need to have their auto modes disabled
for proper operation.
If EZ-Crypt Lite will not run, you may have insufficient memory,
or too many memory resident programs. Try running EZCRL with no
memory resident programs.
If EZ-Crypt Lite just stops running or "freezes", you may have
removed the program diskette from the disk drive. The program
disk must be available to access the context sensitive help and
on-line manual. Of course, if EZCRL.EXE and its support files are
on your hard drive, this will probably not be a problem.
Occasionally, certain memory resident, TSR, or "pop-up" programs
conflict with EZ-Crypt Lite. In general, there is no problem,
but there are many new programs being written without regard to
the system requirements of EZCRL. Remove them from memory, and
try again. If that fails, try getting rid of device drivers in
your CONFIG.SYS file. ANSI.SYS is a prime suspect for some not-
so-compatibles.
13
The latest information on monitors and displays may be put on a
distribution diskette (see Disk #1) in a file called
MONITORS.DOC. To print this information on your printer, just
make sure the file is in the default directory and type COPY
MONITORS.DOC PRN <<cr>>.
Miscellaneous
EZ-Crypt Lite works closely with your computer's hardware to
gain much of its speed. However, it never directly addresses
the hardware without using standard DOS calls. If you have any
memory resident software that modifies the way DOS works, then
EZ-Crypt Lite may not function properly. We strongly recommend
that you remove all memory resident software before running EZCRL!
14
Basic Definitions:
==================
The terms used in EZ-Crypt Lite may be a little confusing. These
terms are not made up, they are frequently used when discussing
cryptography. We have tried to pick a handful of the most
important terms and define them for you. They are:
Cryptography -- The general study of hiding the meaning of
messages and the general techniques used for the hiding.
Cryptanalysis -- The solving or breaking of codes without any
knowledge of the key.
Cipher -- Any technique, method, or scheme (substitution,
transposition, and XOR) used to encrypt and decrypt text,
without regard to its linguist structure.
Plaintext -- The unencrypted or totally decrypted readable text.
Cyphertext -- The unintelligible text, after encrypting it.
Encrypting -- The process of encoding a plaintext file to hide
the intelligence.
Decrypting -- Decoding an encrypted/ciphertext file.
Key -- The text that was used to encrypt or decrypt a file.
Sometimes called a code word. Keys can be simple everyday words
or very complex combinations of characters that have no meaning.
Some electronic information services pick your password by
combining two regular words with a character between them.
Examples keys: abc1234, Never:Again, and alsdkfqiaef.
Substitution encipherment -- Replaces each letter of the original
message by another.
Transposition encipherment -- Rearranges the position of each
letter of the original message, but doesn't change their
identities.
XOR -- Exclusive or, an arithmetic based encryption technique
working at the bit level on characters.
15
Encrypted Ramblings - Some Good Information
============================================
As networks proliferate the need for data security increases.
The world in the past has largely depended on physical security,
that is safes and locks. Computers, much to the bureaucrats
consternation, are rapidly eroding the possibility of physical
security (wherever a modem is connected to a phone line). Laws
will be passed, but in the final result, honesty depends on good
locks and all the ministrations of legislators and bureaucrats
will come have little positive effect on security. Human nature
will win out. The easier it is to get, the more likely it is to
be stolen. Encryption provides part of the answer to the need
for increased security. It will be especially useful in systems
that are open to all users but have some confidential data.
Instead of complex levels of users verification through
passwords, everyone can get the file but only the people with the
key can decode the information. Encryption at its present state
is cumbersome and time consuming but, faster computers and better
programs can ease this problem. This is where EZ-Crypt Lite
comes to the rescue.
Encryption if nothing else is a fascinating exercise. EZ-Crypt
Lite implements a version of Vernham's machine developed at Bell
labs in the 20's. The original machine used Baudot code on the
Teletype and performed an exclusive or (XOR) on each character of
the message and the key to produce the encrypted character. The
message was decoded by the same machine in the same manner. The
method is considered unbreakable if two conditions are met.
First the key is longer than the message and second the key is
only used once, sometimes called a "one time pad." Typically the
files you will be encrypting are much longer than the your key
(also much longer than the one we build from your key) thereby
weakening the encryption.
Distribution and maintenance of keys is unworkable in the day to
day operation of any communications operation of any size. EZ-
Crypt Lite builds a much more complex key from your simple key,
in an effort to provide a method to ease this problem. It
creates a one time pad based on your unique key. Most random
keys are not truly random since all random functions are
repeatable and their true randomness is somewhat suspect. What
is the solution? Always the specter of a bigger and faster
computers loom in the future to provide even faster encryption.
Thinkers build on the best thoughts of those preceding them.
More powerful computers and better encryption techniques will
eventually provide a good solution to this problem.
EZ-Crypt Lite provides encryption methods that range from the
very simple to the complex. Combinations of these encryption
methods are supported. This further complicates the process of
breaking the code.
In our implementation two compromises were made. Potentially
the most dangerous compromise is allowing you to store a set of
16
default keys in a configuration file. So be careful about
allowing access to this configuration file (called EZCRL.CNF).
Another compromise was in using a relatively simple exclusive or
method used in the simpler encryption techniques. Use the higher
numbered methods for more protection.
How do you select a good key? Several things should be
considered. The key should not have a lot of repeating
characters, if they have any pattern to the eye they should not
be used. The keys should be kept secure.
If there is any question of the randomness of the encrypted file,
EZ-Crypt Lite could be used on it multiple times using different
keys. The true randomness of the key should not matter since the
use of more than one key should make unraveling very difficult if
not impossible. This process could be repeated until the
paranoia of the person generating the keys was satisfied.

EZ-Crypt Lite
by EZX Publishing
EZ-Crypt Lite was written by David Black and Perry Kelley.
EZ-Crypt Lite provides multiple methods for encryption and decryption plus
tools to help you analyze the encrypted code. Comments or suggestions for
improving EZ-Crypt Lite will be appreciated.
EZ-Crypt Lite requires an IBM PC or compatible with 384K of RAM. Display
adapters known to work with EZ-Crypt Lite are the IBM monochrome (MDA),
color (CGA), enhanced graphics (EGA), and video graphics array (VGA)
adapters.
#5#
You are currently using the EZ-Crypt Lite On-Line Manual.
Normal commands:
════════════════
Escape -- Escape from the on-line manual.
Home -- First page of the on-line manual.
End -- Last page of the on-line manual.
PgUp -- Previous page (will wrap from first page to last page).
PgDn -- Next page (will wrap from last page to first page).
Any key -- Proceed thru the manual one page at a time, exit on-line
manual after the last page.
Possible errors:
════════════════
1. No manual screen defined for your selected area.
2. Couldn't find EZCRLMAN.TXT. Are both the manual (EZCRLMAN.TXT) and the
index (EZCRLMAN.INX) in the subdirectory specified under the
installation portion of EZ-Crypt? Use the installation portion of
EZ-Crypt Lite to set up a new default help/manual path.
#20#
General help for all menus:
This menu is broken up into two basic windows. The window at the top
of your screen shows several options to choose from. The window at the
bottom of the screen expands on what will occur if you choose the
highlighted option (the one that has a different background color).
Options may be selected in one of two ways. You can either press the
first letter of the desired command or move the highlight bar over the
desired option and press enter. To move the highlight bar use either
the space bar, up arrow, down arrow, left arrow, or right arrow. You can
also use home to move to the first top line item on the menu.
Using the first letter of a command only works in the ACTIVE window. If
you don't have any pulldown then the active window is the top window.
Once you pulldown one of the options that becomes the active window. You
must use one of the commands in the pulldown once it is active. You can
always use Escape to back out of the pulldown and return to the top menu.
#21#
You are now using the EZ-Crypt Lite Main Menu. From here you can
access the main functional areas of EZ-Crypt. Refer to the On-Line
Manual to get a feel for what a fully featured diskette duplicator can do.
Please note that an abbreviated directory window will appear in the middle
of your screen as soon as a valid source diskette has been loaded. It will
show the diskette volume label (if any) and the first four file names.
We have tried to design EZ-Crypt to let you get your job done quickly and
easily. Please feel free to forward any suggestions for improvement to us
at EZX Publishing, Attn: EZ-Crypt Lite Author.

This option allows you to define the default path for accessing the
on-line manual and context sensitive help. Make sure you include the
index files (.INX) along with the help and manual files (.TXT) in the
specified directory.
#55#
This option allows you to enable/disable the sound or beeps on errors.
Some people find programs that beep on errors to be annoying (me for
one). This option will allow you to disable ALL warning beeps in
EZ-Crypt Lite.
#60#
This menu allows you to change all the colors used in EZ-Crypt Lite. To
change a default color - first use the up or down arrow key to select the
color, then type in the new color. When you have changed all the colors
press Ctrl+D to display these colors in a sample window. As with all
installation options, these changes will not be used until you choose the
retain option on the main menu. This allows you to experiment with the
installation options and then not have to lose your original defaults.
Please keep in mind the foreground text colors can be 0-15, the
background 0-7. If you choose a text color the same as a background color
then the text will disappear. You may notice some of your installed color
combinations result in invisible lines on the Ctrl+D popup window.
Please be careful not to choose this color for one of your text colors!!
Note: For many of the EZ-Crypt installable options and user inputs you
will see a prompt containing the characters . If you count the
number of 's you will find the maximum number of characters that can be
entered. Also Escape is used throughout EZ-Crypt to signal "I want out".
Press Enter, up arrow, down arrow, or whatever is asked for to enter the
desired value. Escape will throw away any immediate changes and get
you out of the area you are in.
#61#
Please note that the background color (0-7) is one digit long and the
foreground color (0-15) is two digits long. That is why you will see the
input prompt (the s) change it's width as you go between the colors.
#65#
This screen shows the possible combinations of colors in EZ-Crypt Lite.
If you are using a non IBM display adapter you may have to "play" with the
colors to get a pleasing combination. EZ-Crypt defaults to colors that
work well with the IBM Color Graphics Adapter, IBM Enhanced Graphics
Adapter, and IBM Monochrome Display Adapter.
On some monochrome display adapter clones you may need to alter a
foreground text color to get the background to change intensity.
The default combination of colors will work on any 100% IBM PC compatible
display adapter!
#70#
EZ-Crypt Lite allows the help and manual paths, program colors, etc. to
be saved in a configuration file. If no configuration file is specified
on the command line (ex. C:>EZCRL MyConfg.CNF) when you call up EZ-Crypt
then EZ-Crypt will use the default name of EZCRL.CNF.
You are being asked for the name of the configuration file to load. You
may have several configuration files saved under different names.
Example: BW.CNF (for black and white composite monitors attached to a
composite color card), etc.
Please make sure that the configuration file you are asking EZ-Crypt to
use is really an EZ-Crypt configuration file!
Remember you can always press ESC if you got into this area by accident.

#80#
EZ-Crypt Lite is looking for a valid file name with an optional drive and
directory path.
Example: C:\EZCRL\FileName.EXT
│││ ││ │
╞╛╞═════╛╘══════════╧═ The file you want to use
│ ╘═══════════════════ The working directory
╘═════════════════════ The working drive
Refer to your Disk Operating System (DOS) manual for detailed information
on paths and file names.
#85#
EZ-Crypt Lite couldn't locate any files in the specified directory.
The computer uses a "mask" for directories. The mask used is "*.*".
EZ-Crypt Lite automatically adds this mask to the path for you.
#90#
EZ-Crypt Lite couldn't locate your path. Are you sure you entered the
correct path to get to your file. Computers are dumb, you have to tell
them everything.
Try using the select file option on the main menu. EZ-Crypt Lite will
find all the files in your specified directory and allow you to use a
color bar to select the file.
#95#
Your floppy or hard disk is used to store files. Many times, files will
be organized into groups and stored in specific areas called
subdirectories. The computer needs to be given a location called a
directory, to find the files.
The computer's first "guess" on where to find the files will be your
current default subdirectory (unless you install a default path under the
installation section). Most of the time this will be what you want.
If in doubt, press enter! The files are probably located in the current
directory which is normally the default.
A more technical description follows on the next help page.
#96#
This area allows you to specify the path EZ-Crypt Lite will use to access
your files. You can access files anywhere on your system.
Example: C:\EZCRL
│││ │
╞╛╞════╛
│ ╘═════════ The working directory
╘═══════════ The working drive
EZ-Crypt Lite will ask the computer to tell it all the files on drive C:
in the subdirectory \EZCRL. The "mask" used to get the directory is
C:\EZCRL\*.*. If there are no files in the directory you specified you
may see the error message that says "Could not find C:\EZCRL\*.*".
If you are not sure what you should use just press enter without changing
any of the information. Chances are that the default is what you want
(that is why we made it the default).
Refer to your Disk Operating System (DOS) manual for detailed information
on paths and file names.
#100#
EZ-Crypt Lite will store up to 10 keys within its configuration file for
easy access by you (or someone else with access to your computer). This
feature makes it easy for you to remember keys but should be used with
caution. The keys you specify here can be selected during the encryption
or decryption process using a menu. Be careful of who is allowed access
to your computer if you use this option. The best encryption method in
the world won't protect your data if you give away the key!
What is a key? It is a special access code used to make a file unreadable
to anyone who doesn't have the access code. Just like you can't unlock a
lock without a key, you can't look at an encrypted file without the key.
You limit the number of people who know the key, thereby limiting the
number of people who can access the intelligence within the file even if
they have access to the file. A key is simply a combination of letters and
numbers. They may or may not have any conventional meaning. For example,
the letters xyz12345 could be a key. More keys: never-again, paeirj, etc.
Keys may consist of letters, numbers, spaces, etc. Try to come up with a
key that is unique. Don't use your name, social security number, or any
other item that someone could easily guess after gathering a few of your
personal statistics.
#110#
The name you are trying to save the new file to already exists. EZ-Crypt
is asking if you would like to use the name anyways. In that case the old
file will be overwritten by the new file. You will lose the old file
forever.
If you answer no to -- OK to erase (Y/N)? -- EZ-Crypt will allow you to
enter a new name and will try again using the new name.
#150#
EZ-Crypt Lite breaks up big files into smaller blocks for the encryption
or decryption process. This window gives you the status of the operation.
You will see the block number increase as more of your file is processed.
If an error occurs you will be given a message concerning the problem. A
couple of the possible errors are:
1. EZ-Crypt couldn't find your input file. Please recheck the filename.
2. EZ-Crypt couldn't create your output file. Is your diskette write
protected? Is the disk full?
After the entire file has been processed (encrypted or decrypted) you will
be asked to press any key to continue. The last block processed will
normally be only a portion of a block just to finish off the last portion
of the file.
#200#
Help for Directory Screen: To edit a file use the up or down arrows on the
numeric keypad to highlight a file name and then press enter.
All files in the directory listing are sorted. EZ-Crypt Lite can
handle a directory containing up to 500 files. If you have more files than
that in a SINGLE directory then please break the directory into smaller
ones before running EZ-Crypt Lite.
Cursor key movements:
Up Arrow - Move up one file.
Down Arrow - Move down one file.
PgUp - Move up one page of files.
PgDn - Move down one page of files.
Ctrl+Home - Move to the first file in the directory.
Ctrl+End - Move to the last file in the directory.
Use Enter to select the highlighted file and start operations using it.
#205#
EZ-Crypt Lite will sort the directory you are viewing based on the "field"
you select. It may be:
1. The name of the files.
2. The date the files were last modified.
3. The size of the files.
4. You may also choose the direction of the sort. Forwards or backwards.
NOTE: Do NOT delete files and then use the sort option. Once you delete
a file, it's information is removed from the directory listing and
you will be sorting the "Deleted" message instead of the real
information. This also applies when you press a key during the
file directory to abbreviate the listing.
#210#
EZ-Crypt provides a secure delete command called file wipe. The file is
overwritten first with the binary pattern 10101010 then with the pattern
01010101 followed by the default pattern for a freshly formatted diskette.
This process is repeated three times before the file is finally deleted.
The military typically accepts three overwrites of alternating ones and
zeros as a secure method of completely erasing a file. That is why this
method was chosen.
During the wipe process each byte in the file will be overwritten a total
of nine times. This process will be slow for large files and when used on
a floppy based system.
#300#
IBM ASCII characters range in value from decimal 0 (00 hex) to decimal 255
(FF hex). Please note that the numbers displayed on the screen are scaled
to allow them to fit into a limited space. The scale is displayed on the
window border at the top of the screen and will vary depending on the size
of the file being used.
This screen gives you detailed statistics on both the number of times a
character occurred in a file and some frequently used yardsticks to
measure the quality of the character distribution. Some definitions for
the terms used to describe the data:
Mode - That value which is repeated most often in a data set. When you
look at the statistics you will see the number of occurrences for
each value within the file. The number with the largest value is
the mode.
Median - Middlemost or most central item in a set of numbers. Half of the
numbers lie above this point, and the other half lie below it.
#301#
Mean - Basically the arithmatic average. Add all the values and divide by
the number of values. We commonly refer to this as the average of
a set of numbers.
Std Dev - The standard deviation is a measure of how the characters in the
file deviate from the central value of the distribution (the
mean). This number characterizes the width or variability
around the mean. If you assume a normal distribution, then 60%
of the data will fall within one standard deviation of the mean.
#302#
Listed below are the viewable versions of the ASCII characters (at least
those that could be displayed on your screen from within this program).
This is an IBM ASCII table numbered in hex. The vertical axis is in steps
of 10 hex (16 decimal), the horizontal axis counts up by 1 from the step.

Quick startup info:
EZ-Crypt Lite allows you to encrypt and decrypt files. This means it
allows you to limit the distribution of your important information to a
restricted group of people. EZ-Crypt Lite will give you the ability to
make your important information unintelligible to those who don't have a
"need to know". ONLY those with the correct decryption key can access
your important data.
EZ-Crypt Lite provides four methods for privacy of communication. First,
the simple or fast operation which is basically an exclusive or. Second, a
form of substitution. Third, a form of transposition. Fourth, a slower
combination of substitution and transposition. EZ-Crypt Lite also performs
analysis on your data which can be used to check your encrypted output.
Some people are interested in determining what a message said. Those
people can use the analysis capability to determine what form of cypher as
well as try to break the key of an encrypted message. Efforts at reading a
secret message is called cryptanalysis.
Refer to other sections of the On-Line Manual for additional information.
F1 is always available to call up help while you are using EZ-Crypt Lite.

┌──────────────────────────┐
│ Commonly Asked Questions │
└──────────────────────────┘
1. Does EZ-Crypt Lite (EZCRL) allow me to send software thru the mail
without worrying about unauthorized people getting access to it? Yes!
Both you and the person you are sending the files to need a copy of
EZ-Crypt Lite and the common shared key. Before sending the files thru
the mail, encrypt them using the highest encryption method in EZ-Crypt
Lite (this provides the maximum protection). At the receiving end they
will decrypt the file using the same method and the common key.
2. Can I be sure that no one will ever be able to "read" my encrypted
data? No! All that you can do is make it extremely difficult for
anyone to have access to your data. Your goal should be to make it
more costly for someone to gain access to your data than the data is
worth. EZ-Crypt's encryption methods can be broken but it is very
costly to break the higher encryption methods within EZ-Crypt. It will
cost someone hundreds or thousands of hours of manpower and computer
time to "crack" the higher encryption methods that EZ-Crypt provides.
#100#
EZ-Crypt Lite requires an IBM PC or close compatible with at least 384K of
RAM and DOS 3.0 or later. A hard disk is not required but is recommended
when encrypting/decrypting large files because of the much faster disk
access.
EZ-Crypt Lite provides several encryption/decryption methods for you to
choose from. We are not trying to confuse you with extra choices.
Depending on the type of data you are working with a simple but very fast
method may be all you need. As your need for more protection increases
you can use the slower but safer encryption routines we provide.
#200#
The use of coded messages for secret communications has been a practice
throughout history. Julius Ceasar sent coded messages to his general to
ensure the messages couldn't be read if they fell into enemy hands.
George Washington, during the Amercian Revolution, passed important
information about the British forces in coded form. Today, the US Military
and many large corporations pass important information in a coded or
encrypted form.
The ability to communicate is very important. But there will be occasions
when you may want to limit your information. To limit the number of people
who can read your important information, EZ-Crypt Lite will encrypt and
decrypt your files. You can store or transmit those files to communicate
and still keep your information unintelligible to others.
Some individuals may be interested in determining what your message said.
If this individual obtains a copy of your encrypted message, he will
attempt to determine what your message said. Your message is considered
safe as long as it will take too long to unravel the message, for it to be
useful to the other person.
Some of the fundamental understanding of basic cryptanalytic endeavor, is
taken up in the manual.
#201#
Some basic definitions follow:
Cryptography -- The general study of hiding the meaning of messages and
the general techniques used for the hiding.
Cryptanalysis -- The solving or breaking of codes without any knowledge of
the key.
Cipher -- Any technique, method, or scheme (substitution, transposition,
and XOR) used to encrypt and decrypt text, without regard to its linguist
structure.
Plaintext -- The unencrypted or totally decrypted readable text.
Cyphertext -- The unintelligible text, after encrypting it.
Encrypting -- The process of encoding a plaintext file to hide the
intelligence.
Decrypting -- Decoding an encrypted/ciphertext file.
#202#
Some more basic definitions follow:
Key -- The text that was used to encrypt or decrypt a file. Sometimes
called a code word.
Substitution encipherment -- Replaces each letter of the original message
by another.
Transposition encipherment -- Rearranges the position of each letter of
the original message, but doesn't change their identities.
XOR -- Exclusive or, an arithmetic encryption technique working at the bit
level on characters.

If file privacy and security is a priority, EZ-CRYPT LITE is a powerful
encryption/decryption package that anyone can use. EZ-CRYPT LITE will
encrypt a source file using any one of several methods, and only decrypt
the file using a confidential key. And do it all without cryptic
commands!
Ideal for use with electronic information services and almost any type
of file transfer (both electronic and mail service). Estensive menus,
on-line manual, and context sensitive help make it easy to use. And if
you want file statistics to determine how well your file is encrypted
(frequency/distribution, mode, mean, median, and more) they are
available from within EZ-CRYPT LITE. There is even a ``file wipe''
option to completely erase all traces of your file after deletion.
