Question

Do i need to buy separate SSL certs for www and non-www ?

Let’s say I have a website named example.com hosted here in DO. Currently, I am redirecting all www urls to non-www equivalent. So if a request comes at www.example.com the server will redirect it to example.com.

Now I want to use SSL on my site. My question is do I have to buy separate SSL certs for www and non-www version of the domain ?

Thanks :)

Hi @ozwiz

Most certificate providers will give you www.example.com for free, when you buy example.com

But you can get free signed certificates with Let’s Encrypt. You can follow the tutorial depending if you’re using as web server. Apache: https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04 Nginx: https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04

You do not need to buy separate SSL certificates because Now Single domain validation (DV) SSL Certificate will secure the both www and non-www version of the domain name by default.

Generally, most of the well-known Certificate Authorities such as Comodo, RapidSSL, GeoTrust, Thawte, GlobalSign, etc… issue a domain validation SSL certificate along with WWW and NON-WWW support feature.

If you get single DV SSL certificate from such authorities to protect non-www URLs, which is redirected from www URLs, there will be no issue, because if the CSR is generated for www.example.com then it will automatically work for example.com also.
