    OK, I got the certificate installed, but for some reason, most browsers
    will not install the certificate. Opera won't even try, and IE says it
    installs, and yet asks if you want to trust this server the next time I
    go there. Mozilla works fine. I have a feeling that it is because the
    the CA's root certificate is not available from the web. Am I on the
    right track? If so, how do I fix it? Can I simply register the CA on the
    webserver, so when the client goes to install the certificate, it grabs
    the CA's as well, or do I have to get them to download it seperately?

    There is a concept involved here of a "chain of trust". When Verisign
    signs your SSL certificate, they are giving their promise that they
    trust that you are who you say you are. When Joe User comes to your
    site, he has to decide if he trusts Verisign to make that decision. The
    chain can actually be much longer through the use of intermediate
    certification authorities. A user can "install" a certificate as a
    trusted root, meaning they trust the holder of that certificate to sign
    other certificates. This is the benefit of paying a third-party CA --
    their root certificate is already trusted by a default install of most
    browsers, including Internet Explorer.

    In terms of the public web, if you sign certificates with your own CA,
    the certification chain will end with the certificate of your CA, which
    will not be trusted by most clients. So when they visit your web site,
    they will see an error message that the site is trying to establish an
    SSL connection but the identity of the server could not be positively
    established. This will probably scare people, even though the
    encryption will still work to the fullest extent. In a controlled
    environment, you could install the certificate of the CA as trusted on
    all the client machines and you would have no problems at all.

    What drawbacks are there in becoming your own certificate service?
    Versus one of the major SSL services? Other than that the source of the
    certificate (if the user looked it up) would not be a commercially known
    provider and you couldn't participate in any of the major provider's
    ever so valuable certificate programs.
