WARRANTY AND LICENSE
The programs are sold as-is with no warranty as to fitness of purpose.
A continuous process of Quality Assurance will mean changes to the programs
and there is no warranty to furnish these changes. The buyer by purchasing
these programs agrees;
To not make or cause to be made illegal copies
To not put a program on a BBS or network
To not store a program on more than one computer station
To hold Seller harmless for consequential or incidential damages
The programs are Copyrighted World-wide, and ALL rights are reserved.
Copyright violations which are reported are rewarded by percentage of
recovered damages from a court of law.
If you purchased this series from a vendor, please send us your
name, address, phone, type of computer/accessories, occupation and whether
you are in this type business. You will then get on our mailing list.
Please give us the name, address and phone of the vendor also.
The purpose of The Cipher-Ace Series is to introduce the subject of
Cryptography and Cryptanalysis to a new student of the subject, and
to provide a convenient system for the serious cryptanalyst.
The programs were written by Charles Stewart, who first joined the ACA
in 1977. He was first introduced to Crypto in 1955, as a student at the
U.S. Army Security Agency at Fort Devans, Massachusetts.
The programs could have been written so as to semi-automate the solutions,
but the author feels that would not help the student understand the
underlying principles involved. By following the screen prompts carefully,
and perhaps in conjunction with a text on the cipher type, the student
should have little difficulty in solving most ciphers. The screens have
been prepared so as to reduce the need for pencil and paper.
It is STRONGLY SUGGESTED that the following books be the minimum in your
cryptography libray;
Cryptanalysis, Helen Fouche' Gaines, Dover Publications
American Cryptogram Association, series of pamphlets
The Codebreakers, David Kahn, Macmillan
The programs will handle CT only in the Cipher-Ace format. They will NOT
WORK with standard ASCII text files. However, the menu options allow an
ASCII file to be input and saved in the Cipher-Ace format up to 1000 bytes.
Most ciphers are most readily susceptible to the probable word (or
partial word) method.
Prepared dictionaries of pattern and non-pattern words are generally
available to assist in cryptanalysis, but are not presently used.
Description & layout of the Cipher-Ace series of programs.
Disk Files:
VIGENERE.COM - Application program for that cipher type.
README.GEN - General information on the Cipher-Ace Series.
README.52 - Information for a particular cipher. Vigenere in this case.
READING.TXT - Sources of further information about cryptography
CATESTS.COM - Statistical tests, applied to any cipher message.
LICENSE.TXT - Name of purchaser.
For each application program, it is recommended that the last five programs
be available in the same hard-disk directory.
MASTMENU.BAT MASTER MENU PROGRAM - MENU OF CIPHER TYPES TO LOAD AND
OTHER UTILITARIAN PROGRAMS
##.BAT BATCH FILE TO EXECUTE THAT PARTICULAR CIPHER AND RETURN TO
MASTMENU.BAT
FOR HARD DISK USERS - MAKE DIRECTORY CIPHERS
TYPE> MD CIPHERS ON YOUR FAVORITE DRIVE.
TYPE> CD CIPHERS COPY ALL PROGRAMS TO THIS
ONE DIRECTORY FROM DRIVE A:
TYPE> MASTMENU TO EXECUTE CIPHER-ACE
STORE DISTRIBUTION DISKS SAFELY.
YOU MAY WISH TO CREATE AN AUTOEXEC.BAT FILE TO RUN 'MASTMENU'.
CAUTION: THERE SHOULD BE ONLY ONE VERSION OF 'COMMAND.COM' AVAILABLE.
IF IT EXISTS IN THE 'HD' ROOT, IT SHOULD NOT BE ON A DISKETTE.
IF IT IS ON ANY DISKETTE, IT MUST BE THE SAME VERSION AS IN THE
'ROOT' DIRECTORY.
FOR FLOPPY USERS - USES ONE OR TWO DRIVES - A: / B: AND SUPPLY OF FORMATTED
DISKS FORMAT B:/S (PUTS SYSTEM ONTO DISK).
MAKE A NEW COPY OF EACH DISTRIBUTION DISK, AND SAFELY
STORE AWAY THE ORIGINALS.
FOR EACH CIPHER.COM PROGRAM CREATE A NEW DISK FROM THE
COPY OF THE DISTRIBUTION DISK.
FOR EACH CIPHER TYPE, COPY;
LICENSE.TXT
README.GEN
README.## (FOR THAT CIPHER-SEE MASTMENU FOR LIST)
FILENAME.## (CRYPTOGRAMS FOR THAT CIPHER TYPE)
filename.## information is found in the CIPHER LIST which is part of every
cipher. Just load a cipher.COM program and use ITEM B of the main menu.
YOU WILL HAVE NO USE FOR ANY OF THE .BAT (BATCH) FILES.
HOWEVER, YOU MAY WISH TO CREATE AN AUTOEXEC.BAT FILE FOR EACH DISK.
OTHERWISE, SIMPLY TYPE THE CIPHER NAME AS LISTED IN <filename.COM>.
A word processor available thru pop-up windows, will prove advantageous
for saving the cipher solution, and keywords, in a file perhaps called
ACASOLS.TXT. (Such as Wordstar or Sidekick).
The Cipher-Ace Series Version 1 was developed on the XT computer, and
requires at least 256K RAM for minimal operation. Memory usage is a
contiguous block of 192 kilobytes. The first 64k is for the program
and 2 stacks, the next 64k for holding 15 4k messages and the last 64k
for a text buffer.
Each of the cipher programs are similarly formated, with an option menu on
the first three lines of the workpage. A KB (keyblock) follows, using as
many lines as required, followed by the CT/PT message.
The KB and CT/PT are scrollable if they exceed a certain size.
The prompt line on line 24, allows for quitting, as well as showing the
stack depth and address of the current return stack. These numbers are a
great aid to the original programmer, and may generally be disregarded.
The workpage menu on top of the screen may be customized for individual
ciphers.
Option 'E' calls up another menu of items available during a work session.
Up to 15 ciphers of the same type may be in memory at the same time.
The 'flip msgs' option will sequentially activate each in turn, to make
the displayed cipher the 'current' cipher. The message number is displayed
in the work page menu.
The work page menu options 'E' & 'A' will save back to disk all messages
in memory. Should you have loaded one cipher more than once, then it will
be saved once for each loading. However, be aware that the highest numbered
version will be the last one saved, and lower numbered versions will be
lost, even if they are more highly developed. These options will allow for
the saving of work-in-progress at any stage of solving.
The CHI test (for certain ciphers only) may be applied to the messages
in memory. The PHI test must be suspect for message length under 60-70.
FILENAMING CONVENTIONS <filename extensions>:
.COM an executable program
.BAT an executable DOS level program
.NN a program file unique to a specic cipher type
.PT a text file, containing a plaintext message
.CT a text file, containing a ciphertext message
.TXT a text file containing information about the Cipher-Ace Series
91jae13.2 An ACA cryptogram, year, issue, cipher I.D., cipher type
Your own cipher messages may come from another source other than the ACA.
To input a C.T. message, use main menu option 'E', and either 'A' or 'B'.
Use 'A' to input from the keyboard. Use 'B' to input from the disk with
an .EXT of CT, or input the <filename.ext> of your own ASCII Text
file containing the C.T. for that particular cipher type. The ASCII control
characters and spaces will be stripped from the file newly created. However
this stripping does not apply to ciphers such as ARISTO and RAGBABY.
You may find it advantageous to name your files by the source, with an
appropriate serial number, or by some other convention. In any case,
do NOT alter the .EXT convention.
The structure of the 4k cipher message file is:
0 - 1023 bytes 1k cipher text message
1024 - 2047 bytes 1k plain text message (if any)
2048 - 3007 bytes signal-intelligence data (SIGINT)
3008 - 4095 bytes keyblock structure - alphabets
