BlackBox ver. 3.0 for Windows
**************************************************************************
$$$$$ FINANCIAL REWARD $$$$$
A reward of $300.00 is being offered to the first person who can
break the encryption algorithm. Please see the conditions below.
--------------------------------------------------------------------------
INSTALLING BlackBox
In order to install Blackbox ver. 3.0 insert the diskette in drive a or
b. Click on "File" in the menu and select "Run" in the drop-down window.
When a dialog box appears type a:\setup (b:\setup). To run BlackBox double-
click on the group icon. When it expands double-click on the BLACKBOX icon.
USING BlackBox
BlackBox is a file encryption program. Before a file can be encrypted or
decrypted it has to be selected. The first step in selecting a file is
selecting a disk drive. This is done with the help of the drop down list box
in the top right corner. If you click on the down arrow a list of drives
appears. Click on the desired drive and the directory tree of the selected
drive will appear in the box below. Now you need to select a directory.
Double-clicking on a directory icon will select the directory and display
all the sub-directories in it. At the same time the list of files in the
selected directory will apear in the box on the left. Point the mouse on
the desired file and click. An icon and a text indicating if the file has
been encrypted or not will appear to the left.
In order to encrypt or decrypt a file you have to enter a password. It can
be up to 32 characters long. It is case sensitive and all printable characters
are acceptable. After the password has been entered press the <Encrypt>
or <Decrypt> button. It is critical that you write down the password used
for encrypting files. If you cannot remember the password the file will be
lost for ever. For this reason the password is entered twice. Thus the
possibility of loosing data due to mistyping is eliminated.
When encrypting a file you do not have to specify output. The file will get
encrypted but the name will not change. Black Box "remembers" which files
have been encrypted by a tag attached to each encrypted file.
BlackBox 3.0 can be used in either binary or text mode. Binary is the
preferred and default mode. However, if you need to send an e-mail message
such that a text file is required then use the text mode.
BlackBox 3.0 creates temporary files BLBOX.AUX and TEMP.TMP. If by any
chance you already have files with the same name, please rename them.
Otherwise BlackBox 3.0 will delete them after issuing a warning.
THE ENCRYPTION ALGORITHM
The encryption process is a stream cipher with an extremely large
period. The key stream is unpredictable since it is based on a new,
cryptographically secure algorithm. It uses neither shift register nor
congruential random number generator (although it is a component of it).
Listings are available to registered users (please see FORM.DOC).
Furthermore a reward of $300.00 is hereby being offerd to the first person
who can decipher the enclosed file MYSTERY.BB3. The file contains an English
text. If you send
a) The decrypted content of MYSTERY.BB3
b) The key (password) with which it was encrypted
c) A decsription of the cryptanalytic process
to Algos we will immediately send you $300.00 (Three hundred dollars).
* The encryption algorithm is employed in cipher block chaining mode
eliminating the need for frequent key changes.
* Original files are overwritten three times with alternating patterns
for maximum security.
* The encryption algorithm is available for public scrutiny.
