You have to pass the *class* of the RequestHandler you want, not an
instance. TCPServer will create an instance of such class for every
request handled. So you can't (or shouldn't) save permanent info in the
handler, like rsa_key. Store all those parameters in the server. From the
handler, you may access the server using its .server attribute.
