- This reminds me of something I read on alt.locksmithing. The analogy
- between an encryption system and a lock on the door applies here.
- Locks are meant to keep out respectable citizens, not thieves.
-
- Burglars will not usually go to the trouble of picking the lock on the
- door. It usually takes too much time. Besides, it takes years to
- learn the technique (tools are not hard to get).
-
- Instead, they usually kick the door in, or break a window.
