Program: FEDS.EXE
Author: Richard McMillan
Date: 12/31/92
Compiler: BASIC PDS 7.1 Copyright Microsoft Corp 1982-92
Program description:
FEDS is a file encrytion/decryption program to help in the securing
of data files. It uses it's own software table, much to the likes of an
ASCII table, that may be created or loaded from disk.
FEDS is a self contained command line program that accepts no
parameters. All input is accomplished from within the program itself. A
28 bit header is attached to the front of an encrypted data file to
identify the version of FEDS and the table used in its encryption.
The idea and some methods used in the programming of FEDS were
obtained from the publication, Inside Microsoft Basic, The Cobb Group,
9420 Bunsen Parkway, Suite 300, Louisville Kentucky 40220. Artical:
Encrypting Your Files Without Passwords; Vol. 3 No. 9.
Program Methods:
In essence, FEDS simply scrambles the ASCII table in a completly
random configuration. It then replaces each ASCII character in the data
file with the newly placed FEDS table character. In decryption mode this
process is reversed to obtain a copy of a preencrypted data file.
During decryption, a header in the encrypted file is check to help
insure that the requested file has indeed previously been encrypted by
FEDS and that the correct decryption table is loaded in memory.
Program Status:
FEDS is shareware that retails for $7.95 when, after a short review
period, the user decides to continue its use. This makes it perfectly
legal to copy and share this program with anyone desiring to do so. It
does not however, sanction its use beyond a reasonable period (30 days)
without paying for its use. It also does not permit transfering this
program to anyone without the inclusion of this unaltered text file.
The author of FEDS hopes you benefit from the use of this program.
The author also hopes to benefit by your registering if you use or
deleteing if you don't.
