I’m looking for a SSL Certificate for my WordPress ecommerce site I am developing. I plan on using Braintree or Stripe for credit card processing, but I believe I still need my own SSL certificate for my checkout page. It appears that Dreamhost allows me to purchase any third party certificate. This is my first time doing this, so appreciate any advice.
Couple of specific questions:
The cheapest options secure only single domains, as opposed to also subdomains. I think my site will just have one checkout page that needs SSL (i.e. www.mydomainname.com/checkout). Can I go with the cheaper option then?
Most options claim to be 99%+ compatible with browsers, although some of the more expensive options also mention mobile browsers. Obviously, I would want customers who are using their phones to be able to purchase securely from my website (although I do not have mobile app, just responsive theme design). Do I need to pay extra for this, or would the cheapest options still support mobile customers?
