Thanks for the URL.  However, why does Cisco says:

With the Diffie-Hellman exchange, the DES key never crosses the network (not
even in encrypted form), "which is not the case with the RSA encrypt and
sign technique." - so what about RSA encrypt and sign technique?  I'm very
confused...

Thanks again.
