Ahem, please read this sentence aloud to yourself. Does it sound like a
> # openssl -des3 -out privatekey 1024
> # ./CA.pl -newreq
You mean 'openssl rsa ...' Anyways it is a no-op, given your second
command; i.e., 'CA.pl -newreq' generates a key pair.

This _signs_ your certificate request. Given that you've already gotten
your certificate request signed by a 3rd party CA, this step is
> # openssl rsa < newreq.pem > newkey.pem

Yup this is fine provided your newreq.pem contains your private key.

This sounds like the server is asking for a client cert. Have you
configured your ZServerSSL to do so? I think the server doesn't do that by

Is the 3rd party CA's cert installed into your IE6?

You get a HTTPS connection. You are connecting to a site (well, your own,
in this case) which certificate's CA your browser does not trust.
"Secure" is a loaded word. ;-)

Read up more on how X.509 certificates are structured and on how SSL uses
Then go install one or more other SSL server products. Follow their
instructions on installing certificates. Once you see how different
software packages do the same things it should become clearer to you. Try
Apache + mod_ssl or AOLserver, say. Don't choose one where you configure
the stuff using Windows or web-based pointy-and-clicky interfaces - you
won't learn much that way.
