I'm not sure if you're looking into Diffie-Hellman for the same reason I was,
but here's my story anyway!  Initially I received a bunch of prompts from
Netscape in regards to the certificate when I went to my Apache+mod_ssl secured
test site.  I did not want end users to have to go through this process of
accepting the certificates all the time.

Eventually, I figured out that the reason these pop ups were appearing is
because the signer of the cert is not recognized by Netscape (or IE as the case
may be).  I found that I could post the CA certificate of my CA on a web site
and users can install the CA into the trusted list in the browser.  To avoid the
problem altogether, have the cert signed by Verisign or some other known/trusted
CA which appears in the browsers' lists by default.

I'm sure this is widely understood, but being new to this SSL stuff it took me a
while to figure it out so I thought I would offer it....
