Adding SSL Certificates With Domain Mapping

Hi there,

I am just wondering what the best way to add an SSL cert is with domain mapping on multisite.

I don't have much experience with SSL certs in general.

My situation: I plan on having different levels of Pro-Sites and some will involve an eCommerce aspect to them, for these sites I should install an SSL correct?

I have done a bit of searching and I'm wondering what the experts here thing, what would the best way to include an SSL on select sites in a multisite install. Almost all sub-sites will likely be domain mapped.

Look forward to your response!

Cheers
