Can we add SSL certificate to heroku app having herokuapp.com extension without having a own domain

Question

I am new to SSL concept. I am having a Rails 3.2 application running on heroku.

Can anyone please clarify me about the following things:

If I am having a heroku application "http://example.herokuapp.com", can I add SSL certificate to it without having any own domain (like www.example.com). If so, could you please provide a reference url to that process.

If the above thing is possible, in future if I own a domain (like www.example.com), can I add the same SSL certificate to that domain. Or I need to have a new SSL certificate for it. Or pointing secured (https) url of that application to the new domain (like www.example.com) is sufficient?

Thanks in advance.

You don't have to buy or add anything to use SSL and HTTPS on the .herokuapp.com subdomain, it comes with piggyback-SSL for free out of the box. I.e.: https://example.herokuapp.com/

If you add a custom domain and want SSL on that, you also have to buy a certificate for the domain and add the relevant add-on. That's documented on Dev Center.
