<Hi There Crypto-Nuts>

I would like to stick my neck out and talk about a specific cryptographic
system.  I speak of the system the Fortune 32:16 uses for encrypting their
software releases.

I have recently been playing with a 32:16, and have, just for the fun of
it, been trying to decipher their coding scheme.  So far, I have discovered
the following:

	1. The only files encoded on the disk are the object files.  All
	   others are normal un-encrypted ascii.
	2. The disks are just file systems - i.e. all that's needed is to
	   mount them
	3. The encrypted object files do NOT have the exec header encrypted
	4. The encryption scheme is NOT trivial.

Beyond this, I only speculate, but my speculation leads me to believe that
the encryption scheme uses either crypt(1) or some already UN*X resident
equivalent.  I have not been able to spend as much time as I would like
attempting to break this code, but I intend to figure it out, if possible.
I am NOT a cryptographer (although I continue to learn more about this),
and would appreciate any help I can get from out there.

So far, my plan of attack is to try using the vanilla crypt(1), trying
different 'keys'.

Let me state my disclaimer: I do NOT wish to steal Fortune software in any
way, shape, or form, but I DO resent software companies in general that
think that they can encrypt or otherwise restrict software.  As a simple
example, the 32:16 I work on belongs to someone with two of them, and, using
Fortune's scheme, they would have to buy TWO sets of software!!! (what a rip)
Doesn't Fortune make enough $$$ on their software anyway.  (I'm sorry!
Flame OFF!).

Fortune people, I'm sorry, but if you put a puzzle in front of people, they'll
try to solve it!

For Fortune's sake, please reply (if at all) through mail, as I'm sure they
don't want everybody knowing these things (they'd probably prefer NOBODY)!

Thanks in advance (I hope)
