I want to install HTTPS on my server and I wonder what kind of certificate I will need and where I can buy it.
The site is a web application that demands high security by it's users since they store sensitive business data.
I am also integrating a third party payment gateway into the register process of the site and need a secure way to send credit card data one way. I do not intend to store this data in our own database.
So, what do I need? And also, how do I install it on Ubuntu Server 9.10 / Apache2 ?
