Rubber-hose Cryptanalysis

A timely reminder from xkcd:

  1. The weakest link in a computing system is usually the one between the computer and the user.
  2. The system includes more than just the hardware and the software.

nobody cares about his secrets.  (Also, I would be hard-pressed to find that wrench for $5.)

I expect that Schneier will have something to say about rubber-hose cryptanalysis later.
