OK, you have just written an encryption process that is probably better than
CFEncrypt <g>
How do people turn that back?
Well, what they'd do is monitor your port and send over some known data -
then send over some more... repeat multiple times until they have a
"pattern" - once they know the pattern then they can decrypt your
information whenever they want!
Turning cc details into a garbage string is never silly - it's downright
sensible!
Just don't use CFEncrypt!
