Yes :-) Still very good news as we are on the right way :)

Cool. Is the hardware crypto acceleration of any use for TLS? (Sorry,
don't know anything about the used algorithm)

Cool. Do I have to install the external crypto library? What's about the
licensing?

Ok!

Agree :) Anyway, I had project requests, where the webserver should be
ssl capable. If the system is secure nobody cared about. But for
marketing purposes it should be SSL capable.

Bye,

Ole
