Hi,

Can anybody shed light on the patent restrictions of the RSA public
key algorithm? According to the RSA FAQ, 

------------------------------------------------------------------------------
RSA is patented under U.S. Patent 4,405,829, issued September 29, 1983 and
held by RSA Data Security, Inc.; the patent expires 17 years after issue, in the
year 2000. RSA Data Security has a standard, royalty-based licensing policy,
which can be modified for special circumstances. The U.S. government can
use RSA without a license because it was invented at MIT with partial
government funding.

In the U.S., a license is needed to "make, use or sell" RSA. However, RSA
Data Security usually allows free non-commercial use of RSA, with written
permission, for academic or university research purposes. 
------------------------------------------------------------------------------

Does this mean that a commercial organization outside the US can use a
RSA implementation without legal hassles from RSADSI, or is there some
sort of licensing scheme for organizations outside the US? The BSAFE 
toolkit from RSA is really expensive, and a nice alternative to that
is RSAeuro which is freely available as source code. Any suggestions?
