RSA is the Rivest-Shamir-Adleman public-key encryption scheme. For
details see Koblitz's cryptography text.

As an encryption system, RSA is indeed under the supposed control of our
munitions folks. Furthermore, RSA is (in the United States) patented, so
that for the privilege of being able to exponentiate modulo some large
number in all situations without being sued, you must pay $25 per year
per number.

That would be nice. :-) (I know what you meant.)
