I've never installed an SSL certificate, but I'd like to fully utilize the ProSites plugin and allow users to sign up for their own DIY website on my network. I've been reading all the SSL articles I can find and I'm still confused a bit. I'm using full domain mapping so they can mask their domain at the higher levels of my service.
At a minimum, I know I need SSL on my main site for the checkout process. My clients are mostly churches. Any businesses that end up on my network will likely use off-site checkout (like PayPal).
I'm thinking it would be good to have a wildcard SSL cert. I'm currently masking domains for the entire admin section, but if I did a wildcard SSL, I might consider changing that so that the login page and admin section are covered under my wildcard SSL. (I'm assuming SSL would make the login process more secure--correct?)
Also, I read conflicting information regarding wildcard SSL and domain masking. I've seen some comments (even here on WPMU dev) that say wildcard covers the subdomains but not the masked domain. Then I've read other comments (also here on WPMU dev) that claim wildcard SSL will cover mapped domains that are tied to the subdomains. So I'm really confused about that. If I had clients who wanted SSL, I want to make sure I know if I have to host them outside my network to make that possible or if they can be secured on my network.
I'm hoping to work very hard now at getting the entire ProSites signup feature working. After that, I'm going to consider adding the WHMCS platform to allow my users to purchase domains as part of the sign up process. I'm finding a ton of churches who are doing DIY websites on SquareSpace and I'm trying to build something that can directly compete with them, including offering templates. I think since I'm targeting a very specific niche that I can offer a much better feature set than SquareSpace does for them at similar price points. Most of them know that they will eventually upgrade to a wordpress site, so just having it on wordpress from the get-go will be a big win for many of them.
Thank you for your help!
