title: Value of dh_modulus and dh_gen in OpenID
body: <p>In the association stage of the OpenID process, Diffie-Hellman is used to encrypt the OpenID.session_type value. For using diffie-hellman, we have to generate the value of dh_modulus(p) and dh_gen(g) values. My question is, do I have to generate p and g values each time I send a OpenID request to an OpenID Provider or only during those times when I send a new association.</p>
