- Perhaps he meant that the algorithm would be patented but the design
- details would remain a trade secret; in other words, the "how" would
- be public, but the "why" would remain private. I believe the Data
- Encryption Standard is set up this way: the algorithm is public
- knowledge, but its design is kept secret by the NSA (or whichever
- government agency formulated it).
