The javax-classes can also be taken from Sun, but as they are
export-regulated, we have re-implemented them for our customers outside the
US. I am not aware of what other suppliers of the JCE are providing.

See http://jcewww.iaik.tu-graz.ac.at/legal/patent.htm

There is a patent in the US concerning the RSA algorithm and RSA Inc. is
licensing that and they require you to. You have to talk to them directly
for additional info. If you use the JCE without RSA it is perfectly legal,
if you use our RSA implementation, it would be violating their patent.

.... we provide rsa_rc4 which contains rsa and rc4 (rc4 is claimed by RSA to
be a trade secret). Our iaik_jce.jar does not contain rsa and rc4 to make it
easier for US-customers to avoid getting into problems with RSA:
