- Thanks for the confirmation. That is one-third of RSA and thus does

- This is making too much heavy weather of my inquiry, for what purpose
- I do not understand. The statement which I questioned wasn't that no
- non-Americans had contributed; it was that the assumption of American
- dominance was no longer warranted. I find this puzzling given the
- work I'm familiar with, and what has seeped under the door about the
- NSA's budget and quality of their personnel.

- Phil follows this by a discussion of others' ability to copy software or
- develop software from algorithms. That point is not at issue here.
