Standard SSL to protect multiple subdomains

I have a domain(GoDaddy), say example.com and standard SSL certificate to protect it. The combo works fine to setup a secured website hosted in Apache2 at https://www.example.com

Can the same SSL certificate be used for more subdomains like https://api.example.com and https://learn.example.com?

Solution

  • Standard SSL certificate can only secure single domain name for example example.com but it can secure api.example.com, learn.example.com but for that you will have to purchase separate standard SSL certificate for each sub domain.

    So in this case Wildcard SSL certificate will remain the best option to secure first level of unlimited sub domains of the main domain name (example.com) like api.example.com, learn.example.com,payment.example.com etc. etc.
