- I fail to see your point. Are you claiming that RSA was obvious?
- I suggest you read

- Believe me, it wasn't obvious to a lot of smart *and* educated people.
-
- Yes, RSA is eminently comprehensible now, almost obvious, one would say.
- Lots of brilliant inventions are obvious in retrospect. So what?
-
- To my way of thinking, RSA is about the best example there is of why
- ``software'' patents should be valid. Apart from the technicality that
- it can be (and often is) implemented in hardware, we have something that's
- new (that factoring is difficult isn't new -- but a practical use is),
- useful (or we'd be discussing this in sci.math, not sci.crypt), and
- very definitely non-obvious.
