I'm a newbie to this kind of hosting - I previously used Homestead.com :disagree: (similar to Geocities) - and my host has SSL installed.

Could someone tell me how to set up SSL on my site? I checked port 443, and it exists, so I know that SSL is working. I just don't know how to get it so that someone could access my site or a directory or even subdomain securely, using https://...

Thanks!

The usual method as follows

https://secure.domain.com/~user/

(Where secure.domain.com is the address as per the ssl cert - your host will tell you this address and ~user is your user name for your account)

If you get your own ssl cert, just use https://secure.domain.com

secure.domain.com can be any subdomain for your main domain you choose - your cert is configured with that address.
You need to complete a CSR - again your host will help with that.

Hope that gives insight :-)
