Secure web form

[Schoolie]

I am putting together a registration site for a conference. I put together a simple web form but I want to secure the data that gets sent from that form.

The form includes a credit card number field and I don't want that to be transmitted through clear text.

How can I most quickly get this accomplished? I have no SSL certificate installed on the server.

Correct me if I'm wrong, but wouldn't an SSL certificate or something similar be required (or at least strongly perferred among customers) to have this done ?

Yes, you are correct Stewart. SSL Certificates are the best ways. There are alternative methods though.
