The Scrambler ][
⌐1994 R.J. Nataly - All Rights Reserved
Welcome to version 2.0 of The Scrambler. This version is very similar in
operation to its predecessor, but employs a more sophisticated encryption
technique. One difference you'll immediately notice is that the encryption
password has been expanded from four digits in version 1.5 to eight digits
in this version.
Other than the increase in the password length, all other aspects of
operation remain unchanged. Because The Scrambler][ is relatively
simple to use and is very similar to version 1.5, this documentation will be
fairly brief.
Both versions of The Scrambler require you to have:
mathieeedoubbas.library
in the LIBS: directory of your system disk. This library file is contained in
Workbench version 2.04 (and possibly earlier versions of WB as well).
Scrambler][ Overview
The Scrambler][ will read an ASCII text file and encrypt it using an 8-digit
password that you provide. The resulting output file can be read only after
decrypting it with the same 8-digit password.
An effort has been made to avoid non-printing, control, and other unusual
characters in the Scrambler][ output file (the encrypted file). This allows
encrypted files to be placed in E-mail and public message sections of most
bulletin boards.
However, if the bulletin board inserts characters while printing the
message (a [pause] prompt, for example), then these characters must be
deleted from the message before de-Scrambling.
For absolute best results, messages should be uploaded/downloaded via
the bulletin board's file transfer area.
Scrambler][ Operation
The Scrambler][ can only be run from a Workbench Shell (CLI). Running
the program by typing "Scrambler" will give you the following help
screen.

----------------
⌐ 1994 - Bob Nataly
Usage: Scrambler <operation> <########> <filename>
Operations: -s = Scramble an ASCII file.
-u = Unscramble an ASCII file.
######## = An eight digit password.
As I mentioned before, operation is fairly straightforward. To encrypt a
file named secret with password 84620321, simply type:
Scrambler -s 84620321 secret
to decrypt the file secret.scr, type:
Scrambler -u 84620321 secret
That's all there is to it.... I've enclosed a file called testfile.scr for you to
unscramble with the password 12345678. Read the file before
unscrambling it, then read it again after unscrambling it. This will give
you a better idea of The Scrambler]['s capabilities.
Legal Notice
The Scrambler][ was not written for use as a means to communicate illegal
activities and should NOT be used as such. I do NOT support the theory
that its OK to break a particular law if you don't feel it should exist. If you
don't like a law, then gather support to repeal it legally.
I realize that others uploading such programs have suggested using them
for communications dealing with illegal activities. Such suggestions are
socially irresponsible and morally questionable. In response to such
suggestions, I'll simply offer this warning. Local officials have the ability
to transfer encrypted messages to federal agencies, should probable cause
exist. Federal agencies have specialists trained to decode any encrypted
message, regardless of the encryption method used.
While The Scrambler]['s encryption method is sophisticated, I will
cooperate with any law enforcement agencies in their efforts, providing
probable cause exists.

Scrambler.doc - This file
testfile.SCR - Sample scrambled file
Scrambler - Amiga EXE file
The PC version should be identical to the Amiga version in every aspect,
although I have not tested the PC version as completely as the Amiga
version.
NOTE:
When transferring .SCR files from PC to Amiga via disk, you may have
to use the AmigaDOS ED command to remove extra carriage returns from
the file for it to unscramble properly.
BUG REPORTS:
Please send any bug reports to:
Amiga@CIS.UmassD.edu
please be sure to identify wheather you're using the Amiga or PC version.
