-
- Spoken _ex cathedra_. I think an encryption might be extremely
- easy or extremely difficult to break whether one has a "copy of
- the mechanism" or whether one doesn't. In the real world, during
- a practical attempt at breaking a code, you might not have the
- algorithm.

- We are not being cute. We wanted to make a test, and the test may
- or may not work, we don't know. Or, if the test works, we may
- loose or we may win, we don't know. Or, if we loose, it may mean
- something or it may not, we don't yet know. These things remain
- to be seen, but there are other avenues open as well. We just
- though you guys might enjoy a simple little challenge... :-) But
- the cryptolibido here seems so low... tsk... tsk... the
- crypthormone levels are waaaaaay down...

-
- We've really not claimed that. We haven't claimed anything. But we
- will not publish the algorithm for reasons already explained.

-
- By now, Id' tend to say: sadly, yes. But _strangely_? I don't
- know... my feeling is that you've run across the NIH syndrome as
- well.
