- Don't need to buy it: you can get PGP which is an excellent RSA
- implementation for free from a whole host of sites. You can even ftp it
- from the US if you like :-)

-
- Tru, I was being sloppy: the US Govt defines encryption technology as
- "munitions", but the NSA (or its forerunners) probably had a hand in
- drafting the definition.

-
- RSA, Inc. no longer owns the patents: they are owned by Public Key
- Partners, who appear to be just a litigation company waiting for somebody
- to infringe, and then sue.
