Information about “UTILITY POTLUCK”
Are you looking for a nifty little gimmick to customize your own
shareware release or perhaps the disks you share with friends or members
of your local users group? If so, get DISK SIGN.
DISK SIGN is a simple, inexpensive package that lets you place a
customized message of up to three lines in length into the DOS
directory. The message is displayed each time someone uses the DIR
command on the disk. The special title or business name is displayed in
vertical columns and outlined in borders for emphasis. Operating this
package is easy and uses very little memory. One of the more clever
promotional or marketing ideas to come around in a while!
Keep sensitive data protected with CIPHER -- a powerful encryption
package that can turn any file into an unintelligible jumble of random
characters. Only you have the key to unscramble it back into a readable
form. Each encoding can have up to 50 printable characters. And,
unlike most other file encryption schemes, CIPHER is very difficult to
uncode because it's based on sophisticated techniques similar to those
used by U.S. Government agencies.
AUTONUM is a simple, useful program for assigning sequential numbers
(seven digits max.) to such items as purchase orders, invoices,
statements, checks, memos, and many other business forms. It works by
using batch files to effectively automate the numbering process and
reduce the possibility of repetitive errors.
If you're tired of typing multiple keystrokes to execute common DOS
commands, then MASTERDOS can relieve your keyboard-cramped fingers. DOS
commands are reduced to single keystrokes making the overall
operation of your DOS-based machine a breeze. Master configurations are
stored as data files to eliminate re-entering of data. MASTERDOS has
selectable terminal emulations and includes commands to copy files,
change drives, erase files, locate files globally, reorder files
on-screen, type files, and perform many other features.
Learning MASTERDOS requires minimal training time, and on-line help is
only a function key away. Six pages of well-written documentation
cover the basics of operation.

APPLICATIONS & USE
==================
AUTONUM is intended for use with batch files on IBM PC,XT,AT micro
computers. It's main applications lie in small business or similar
installations where it is desireable to use sequentially numbered
documents such as purchase orders, invoices, statements etc.
A typical installation would be as follows:
Batch files are prepared for Invoicing, Purchasing, Statements, Work
Orders etc accessed by either function key assignments or short
descriptive names such as 'INV', 'PURCH', etc. which switch directories
as necessary, call up the program, process the required application and
return you to your specified directory.
You use your favorite word processor to do the actual form filling, be
it Wordstar, Word Perfect etc. This program prepares a copy of your
basic form to be filled out and gives you the number to apply to it.
It can also be used in purchasing for example to look up the next
Purchase Order number quickly while on the phone to a supplier, without
continuing on into the form preparation until a later time.
TYPICAL BATCH FILE
==================
Filename 'INV.BAT'
ECHO OFF Turns off the screen while the batch file runs.
CLS Clears the screen
CD\FINANCE\INV Change directory to where invoices are located
AUTONUM Runs the AUTONUM.EXE program.
CD\WORK Returns you to your normal directory on completion
CLS Clears the screen
In our application here this handles our invoicing, a second batch file
'PURCH.BAT' deals with all purchase orders. In that case line 3 changes
directories to \FINANCE\PURCH.
INITIAL INSTALLATION
====================
The first time that you run AUTONUM on a new directory you will be
presented with a screen of information advising you to note down before
continuing such items as:
(1) The command used to invoke your word processor.
(2) Any prefix used on your document numbering such as PO, INV etc.
(3) The starting number of the form series.
(4) The name of the blank form which the program will copy for you to
fill out.
Note. The maximum combined prefix and form number is 7 characters.
You then have the option to continue and install the program or stop
and prepare the necessary data and blank form.
When you do install the program it produces a small file called 'FNREC'
which contains the up dates for serial number, word processor name and
other data the the program needs. If you destroy that file the next
time you run AUTONUM you will automatically be required to re install
it.
IN CONCLUSION
=============
The program copy on this disk is intended for demonstration and trial
purposes only. When you find how useful it is and send us your
registration we will send you a commercial free latest revision
together with any other current data or applications suggestions. You
will be entitled to free updates as they occur during the first year

1 INTRODUCTION
Cipher is a program that scrambles files so that no one can use them -
unless they have the correct key. (If you're familiar with earlier versions
of Cipher, look at section 8 to learn about new enhancements.) Cipher
provides the following benefits:
* Protection is provided by a reliable, documented method that is highly
resistant to attack - even by expert programmers and cryptographic
analysts.
* Cipher is easy to use - it protects you from mistakes and helps you to
remember keys.
* Cipher is faster than other programs that provide comparable security.
* Cipher can encrypt files in place, so unerase utilities can't recreate
them.
* Cipher can also make a new encrypted file and leave the original file
untouched - this is useful when sending an encrypted file to someone
else.
* Cipher can be used from batch files to provide security automatically.
* Cipher is less expensive than commercially available programs.
* Cipher guards against changes to itself - you can be sure you have an
unmodified Cipher and also detect any subsequent tampering.
* All proceeds of Cipher go to Oxfam America, an international self-help
and disaster relief organization.
Cipher encrypts and decrypts files using a cryptographically sound method.
Encryption makes a file unintelligible and useless. Decryption is the
reverse - it converts the encrypted information to its original understandable
form. The encryption is controlled by a key that you provide. You can use
any string of characters you like. When you want to use the files, you
decrypt them using the same key to return them to their original form.
Someone who doesn't know the correct key or doesn't have Cipher is powerless
to make the file useful again.
Cipher protects you from common errors such as decrypting a file with the
wrong key, decrypting a file that's not encrypted, or encrypting a file twice
(unless you specifically request it). It also helps you remember your key -
you describe the key when you encrypt (e.g. "my old Corvette license number"),
- 1 -
and Cipher displays your description when you decrypt. You can control Cipher
interactively, with command line arguments, or via an MS-DOS environment
variable. Cipher is also well suited to batch file use.
Cipher runs on any MS-DOS compatible machine (IBM and BIOS compatibility
is not needed) using MS-DOS 2.00 or later, and uses 64K of memory. All
standard display adapters may be used as long they display at least 80
characters per line. Files may reside on floppy or hard disks and be any type
or size.
Note that Cipher keeps people from understanding and using the contents of
your files, but doesn't prevent normal file operations such as deleting,
copying, or renaming. If you're concerned about someone destroying your data,
Cipher doesn't help. Cipher does protect against the introduction of false
information. Someone can modify an encrypted file, but they can't achieve a
specific result because decryption affects their changes in an unpredictable
way. Consequently a file that is modified in its encrypted form will have
garbage in the changed portion of the file when it's decrypted.
Remember that you MUST specify the correct key to decrypt a file and make
it useful again. Cipher will help you recall the key and tell you if you
enter the wrong one, but it doesn't remember the key for you. If you forget
the key there are no shortcuts or bypasses - you're stuck with a useless file!
Since Cipher encrypts files in-place to ensure security, Norton utilities or
the like won't help. Cipher has no trapdoors that let you, me, or anyone else
decrypt a file without the key, so BE CAREFUL!
If you want to try out Cipher right now, just run Cipher with no command
line arguments. Cipher will display a brief description of its operation that
you can use to get started. While you're getting used to Cipher, be sure to
work in a test directory with test files to ensure that you don't irrevocably
scramble something important.
2 OPERATION
You control Cipher by command line arguments that specify the commands to
be performed, options, and the files to be encrypted or decrypted. The
commands and options must precede the files on the command line and be
separated with blanks. You can specify multiple options, but only one
command. You can use one of the following commands:
COMMAND MEANING EXPLANATION
-e Encrypt Encrypts the files and prompts you for the key.
You are only prompted once - the key you enter is
used for all the files.
-e<key> Encrypt Encrypts the files using <key>.
-d Decrypt Decrypts the files and prompts for the key.
Cipher will only decrypt encrypted files. If the
- 2 -
files were encrypted with the -i option, Cipher
helps you remember the key by displaying the key
description you provided. If the key you specify
is incorrect, Cipher prompts you for the correct
key.
-d<key> Decrypt Decrypts the files using <key>. This command
works like -d above except that the key provided
with the command is used.
You can use the following options:
OPTION MEANING EXPLANATION
-i<desc> Info Saves a description of the key used to encrypt the
files. When you encrypt or decrypt the files,
Cipher displays the description for you in the key
prompt. For example, you could use "my student id
number at Penn State".
-r Re-encrypt Lets you encrypt a file even if it is already
encrypted. This is useful when two people want to
control the use of one file - each person can
encrypt with his own password. Encrypting a file
more than once also provides even greater
security. A file encrypted more than once must be
decrypted in reverse order of encryption, i.e. the
first decryption must use the key from the last
encryption.
-s Suppress Suppresses screen list of the name of each file
processed or skipped - only a summary is shown.
Error messages are not suppressed.
If you specify the file names on the command line as described above,
Cipher encrypts or decrypts the files in place. File names can include drive
letters, paths, and wild-card characters ("*" and "?") in the standard MS-DOS
format. To specify multiple file names, separate the names with spaces.
If you want to make a new file and leave the original file untouched, use
input and output redirection (invoked via the "<", ">", and "|" command line
options) to identify the files. File redirection is described in the MS-DOS
manual under "Redirecting Command Input and Output". You can only process one
file at a time this way. Make sure the input and output file are different,
or the file will be destroyed. An example of redirection is shown in the last
example below.
- 3 -
Some examples of Cipher use are as follows:
cipher -eMike -i"my first name" test.*
All files in the current directory matching the name test.* are encrypted
in place using key "Mike". When you decrypt the files the key description
(i.e. "my first name") will be shown with the prompt.
cipher -d a:\mp\data\*.* a:\wp\*.*
All files on drive a: in directory \mp\data and \wp that were previously
encrypted are decrypted in place. Unencrypted files are left alone. You
are prompted for the decryption keys. Cipher remembers the keys you enter
during the run, and only prompts you for different keys.
cipher -eMike
All files specified interactively (i.e. in response to Cipher's prompt)
are encrypted in place using the key "Mike".
cipher -eMike <letter.src >letter.snd
File letter.src is encrypted with key "Mike" and written to file
letter.snd. File letter.src is not altered.
If you want to interrupt Cipher at any time press Ctrl-C. If Cipher is
waiting for input from you it will terminate immediately. If Cipher is
encrypting or decrypting a file, it will terminate when the operation is
complete.
Note that Cipher gives you the capability to protect your information, but
doesn't guarantee safety. To ensure security there are several things you
should remember:
1. Don't hard-code your keys in batch files. Anyone can run or examine
them and decrypt your files.
2. Don't use keys that can be easily guessed, such as your initials or
your girlfriend's first name. This sort of thing is the first method
most attackers will try.
3. Don't write your keys down and leave them somewhere they can be found.
4. Be careful with the -i (key description) option. To be safe, you must
refer to information only YOU know.
5. Use long keys. It's common to use short keys because they're easy to
remember and enter. The problem is that exhaustive testing of all
short keys could succeed with relatively little effort. Use at least
8 characters for good protection, and 15 for maximum security.
- 4 -
6. Use the cryptographic checksum feature (described in section 3) to
protect against Trojan horses or other attacks. It's surprisingly
simple for a knowledgeable attacker to patch a program so it does what
he wants.
7. Watch out for portions of confidential files that may remain on your
disks. Normal operations (e.g. editing a WP document or a spread
sheet model) can leave copies of parts of your files in unused
portions of the disk. A knowledgeable user can poke around the disk
looking for interesting stuff. This information may reside in two
places: unallocated clusters, or the unused portion of the last
cluster of a file. The first case is easy - unallocated clusters may
be zeroed using Norton Utilities Wipedisk with the /E option. The
second case is tougher because your data can be at the end of ANY
file, not just the one you're using. Cipher takes care of the file
being encrypted by zeroing the unused area at the end, but it doesn't
do the same for all the files on the disk. You can partially protect
against this problem by running Wipedisk immediately after running any
program that alters files containing confidential information. This
clears the information before at has the chance to be included in some
other file. The only way to completely protect against this problem
is to delete all unencrypted files (or encrypt all files) on the disk
and then using Wipedisk or the like to zero all unused sectors.
This all sounds obvious (except for item 7), but many attempts at security are
compromised because of this type of carelessness.
3 ADVANCED OPERATION
If you don't specify enough information via the command line, Cipher
prompts you. If you don't code -e or -d, Cipher asks if you want to encrypt
or decrypt. Cipher also prompts you for the key, the key description, or the
file names if you don't specify them. File names can include drive letters,
paths, and wild-card characters in the standard MS-DOS format. To specify
multiple file names separate the names with spaces. When you enter file names
from the prompt, Cipher lists the name of any files skipped, even if you
specified the -s option.
You may also specify commands and options (but not files) in the
environment variable CIPHROPT. You can use all commands and options available
from the command line.
If someone alters Cipher you can detect the changes with the cryptographic
checksum feature. Detecting changes is important because an attacker could
modify Cipher to encrypt files using a weaker method, write all keys to a file
only he knows about, or compromise the protection in some other way.
Detection is guaranteed only if the Cipher you have has not been tampered with
before you received it - see a later paragraph for detecting this situation.
To compute the cryptographic checksum, run Cipher with the -c command.
Cipher asks you for a key, combines this key cryptographically with the file,
- 5 -
computes the checksum, and displays it. You can use any key you want. If
anyone changes the file or you use a different key, the checksum changes too.
Someone who wants to compromise Cipher is frustrated because they don't know
what key you are using, so they can't make the corrupted Cipher display the
right checksum. If you compute the checksum when you receive Cipher and write
down the key and checksum in a safe place, you can recompute the checksum at
any time to check for changes. As long as you keep your key secret (and you
started with an unmodified Cipher), no one can change Cipher and still have it
produce the same checksum.
The cryptographic checksum feature is also used to detect corruption of
Cipher that occurred before you received it. You can detect Trojan horses,
viruses, or any other alterations to both the program and this documentation.
To test for changes you use a key/checksum combination that you can request
from me you when you register. You compute the checksum for your Cipher using
the key I provide. If your Cipher doesn't display the checksum I send, your
copy of Cipher is corrupted. Since I send a different key (and checksum) to
each registered user, no attacker will be able to obtain your key and checksum
and circumvent the protection. (Note that when you run any unknown program,
including Cipher, you run the risk of it performing mischief on your system,
so be careful. It's probably not too helpful to learn that the checksum is
invalid if a Trojan horse has just erased your disk!)
4 OPERATIONAL DETAILS
This section describes some details of operation that may be of interest,
as follows:
1. Cipher is careful not to encrypt itself. This protects you from
scrambling Cipher and having no way to unscramble it.
2. When Cipher encrypts or decrypts a file it doesn't alter the file's
attributes or date/time stamp.
3. Cipher will not alter files with the system, hidden, or read-only
attributes.
4. Encrypted files contain all 256 character combinations even if the
original file only contained ASCII. If you want to transmit an
encrypted file via a modem make sure you use a communication protocol
that supports binary files.
5. The key may consist of up to 50 printable characters. Upper and lower
case characters are considered to be different. If you enter too many
characters or a non-printable character you are notified.
6. It is possible that on a full disk Cipher will run out of disk space
when it tries to append the encryption mark to the end. (The mark is
described in section 5). If this occurs you will be warned. No
damage results - Cipher does not encrypt the file in this case. This
problem doesn't occur with decryption.
- 6 -
7. It is possible that even with the safeguards built into Cipher and
careful use you will find yourself with an encrypted file and only a
vague memory of the key. If you just can't guess the right key,
you're stuck. Perhaps a close personal friend who works for the
National Security Agency could help, but short of that there is no way
to recover. I can't help you. Sorry, but that is, after all, the
whole point of this product.
5 TECHNICAL INFORMATION
The encryption method used in Cipher is described in the paper "Wide-Open
Encryption Design Offers Flexible Implementations" by Robert Scott,
CRYPTOLOGIA, January 1985. Scott's method uses principles derived from the
Data Encryption Standard (DES), a standard for commercial and non-military
governmental data encryption adopted by the National Bureau of Standards in
1977. The Scott method employs a longer key (providing greater security) and
executes more rapidly than the DES method. The algorithm is coded in assembly
language and optimized to make it as fast as possible. Cipher augments the
Scott method by randomizing the file before encrypting it. This makes the
encrypted text even more secure, and ensures that patterns in the source file
cannot be detected in the encrypted file.
It should be noted that methods used by many commercial encryption
products are not as secure as claimed. The paper "A survey of Data Insecurity
Packages" by Martin Kochanski, CRYPTOLOGIA, January 1987, evaluated the
methods used by SuperKey (Borland International), Padlock (Sovereign
Software), PS3 (Stralfors Data Products), Crypt (BCS), and N-Code (K+L
Software). Kochanski found that "all these packages are vulnerable to known-
plaintext attacks; some with as few as 6 bytes of plaintext needed. Moreover,
all the packages except N-Code can be broken quite effectively without any
known plaintext at all." He demonstrated his point by breaking the packages
using standard cryptanalysis techniques and an IBM PC. The techniques he used
are known to students of cryptanalysis and could be employed by anyone who
wants to steal your information or invade your privacy. The bottom line is
that if you want to be sure about the security of your files, you must be very
careful in selecting an encryption package.
Kochanski did not examine the Scott method used in Cipher. He did point
out the weakness of the methods he examined - "All the packages we have looked
at suffer from a lack of diffusion: a small change in the plaintext causes
only a small change in the ciphertext." The Scott method allows each bit of
plaintext to affect 64 bits of ciphertext. This diffusion is the same used in
the DES method.
Cipher takes additional measures to ensure security. Files are encrypted
and decrypted in place (except when file redirection is used) to ensure that
the original information does not remain on disk. This also avoids running
out of space on full disks. When files are encrypted in place, the unused
portion of the last cluster of the file (which often replicates data in the
file) is zeroed so that no unencrypted information can be found there.
- 7 -
The marking feature that enables Cipher to recall information about an
encrypted file is implemented by appending information to the end of a file
when it is encrypted. This information contains an encryption signature (used
to determine if the file is encrypted), the key description (that is displayed
in the decryption key prompt), and some encrypted text (used to recognize the
correct key at decryption time). Note that the encryption key itself if NOT
included. The file is returned to its original length when it is decrypted.
The cryptographic checksum feature was suggested by Dr. Fred Cohen in the
paper "A Cryptographic Checksum for Integrity Protection", Computers &
Security #6, 1987. Cipher uses the Scott encryption method instead of the RSA
cryptosystem and reduction in modulus described by Cohen. Each block of the
file is combined with a number indicating its position in the file, encrypted
with the user-provided key, and added (without carry) into the cumulative
checksum. As a result any change in a character of the file or its position
is reflected in the checksum.

Version 1.2 will decrypt files encrypted by versions 1.00 and 1.1.
Versions 1.00 and 1.1 can only decrypt files encrypted by themselves.
Added encryption of files that are already encrypted. This lets two
people control the use of one file - each person can encrypt with his
own password. It also provides even greater security. The feature is
invoked via the -r option.
CIPHER version 1.1 - 7/1/89
Added encryption/decryption of files without overwriting original
file.
Enhanced encryption method to ensure that patterns in the original
file cannot be detected by examining the encrypted file. Note that
files generated by Cipher versions 1.00 and 1.1 are incompatible.

PC-SIG version: 1.1
Are you looking for a nifty little gimmick to customize your own
shareware release or perhaps the diskettes that you share with friends
or members of your local users group? If so, DISK SIGN just might be
the ticket!
DISK SIGN is a simple, inexpensive package that lets a user place a
customized message of up to three lines in length into the DOS
directory. Thus the message is displayed each time a directory (dir)
command is invoked on the diskette. The special title or business name
is displayed in vertical columns and outlined in borders for emphasis.
Operating this package is neat and easy and it utilizes only minute
amounts of available diskette memory in the process. Certainly one of
the more clever and innovative promotional or marketing ideas to come
around in a while!
So...you say you're worried about your wife, Mother, or the FBI finding
those computer files containing your secret love letters to Jody
Foster?? Well, you need no longer fear because CIPHER is here!!
CIPHER is a powerful, inexpensive encryption package that turns any
desired file into an unintelligible jumble of random characters. Only
you possess the key that can unscramble it back into a legible form --
an encoding key that can consist of up to 50 printable characters. And,
unlike most other file encryption schemes, CIPHER is for all intents and
purposes unbreakable and is based upon sophisticated techniques similar

AUTONUM is a simple, useful program for assigning sequential numbers to
such items as purchase orders, invoices, statements, checks, memos, and
many other business forms. It works by using batch files to effectively
automate the numbering process and reduce the possibility of repetitive
errors.
Batch files can either be accessed by function key assignments or by
short descriptive names. The batch files make the necessary directory
changes, initiate AUTONUM, complete the required procedure, and then
return the user to a specified directory. The maximum number of
characters that can be used in a given application is seven.
If you're tired of typing multiple keystrokes to execute common DOS
commands, then MASTERDOS can help relieve your keyboard-cramped fingers.
MASTERDOS has selectable terminal emulations and can copy, change
drives, erase files, locate files globally, reorder files on-screen,
type files, and a host of other useful features.
MASTERDOS reduces common DOS commands to single keystrokes making the
overall operation of your DOS-based machine a breeze. Learning
MASTERDOS requires minimal training time and on-line help is only a
function key away, anytime you're forgetful. Once established, master
configurations are stored as data files to eliminate the necessity to
re-enter the data. Six pages of written documentation cover the basics
of operation in an understandable format.
Usage: Programming Utilities, Business Utilities, DOS Level Utilities.
Special Requirements: None.
How to Start: Type GO (press enter).
Suggested Registration: $25.00 for AUTONUM, $35.00 + $5.00 for shipping for
MASTERDOS, $20.00 for DISK SIGN, $40.00 for CIPHER.
