What SSL certificate should I buy to get my domain work?
I use nginx web server and want that all users requests go to https. 

http://example.com -> https://example.com
http://www.example.com -> https://example.com
https://example.com -> https://example.com
https://www.example.com -> https://example.com

Do I have to buy 2 certificates for both domains example.com and www.example.com?
Or may I buy only one certificate with subdomain support?
What does SAN mean in SSL-certificates and how can it help me?

What nginx config do I need to get desire redirection?

Thanks.

I think some certificates now support the www and non-www as a single certificate, without buying the whole subdomains support, it would be cheaper than the subdomain one, contact whichever provider you are considering and ask them if they support the www subdomain of the domain or not.
