%%% where the Diffie-Hellman parameters are signed by a DSS or RSA
%%% certificate, which has been signed by the CA. The signing
%%% algorithm used is specified after the DH or DHE parameter. The
%%% server can request an RSA or DSS signature- capable certificate
%%% from the client for client authentication or it may request a
%%% Diffie-Hellman certificate. Any Diffie-Hellman certificate
%%% provided by the client must use the parameters (group and
