How to Implement Fasthosts SSL?

I need to implement my SSL certificate from fasthosts, but I honestly have no idea how to do this. I need to make the SSL work on my website; I especially need it for google checkout. If someone could tell my step by step how to do the SSL I'd appreciate it.

Thanks

The Fasthost's data vault approach is a nightmare for complex dynamic programs like Zen Cart that rely on secure access. The simplest way to work with it is to copy your entire file structure into the vault and then edit your configure files so that SSL accesses go there instead of your main hosting space.

However there are two significant problems with this approach:

1. Firstly, the allocated space may not be big enough. In that case you get into to trying to pick apart which bits of Zen Cart are accessed when building secure pages. I really wouldn't recommend even considering trying to do this.
2. Secondly, when you make changes to your site you will need to remember to always do them in two places.
   Personally I'd recommend looking for a different host that uses a normal SSL certificate approach.
