Re: randomizing keyboard input

It might slow down non-hardware keyloggers. The thing is there is
software that can unrandomize simple letter exchanges. So if I capture a
few paragraphs of keystrokes it should be fairly easy (possible even by
hand) to determine the correct letter exchanges. Nice Idea but unless
you had hardware and software that worked together (like the smart cards
that change pins every sec minutes). What you need is keyboard that
encrypts the keystrokes and then software reversed it. Again the problem
is If i can run software on your system (ie a keylogger) I can probably
run anything I want.
