You will need an SSL certificate to serve an SSL application. The issue with an SSL certificate is that it needs to be trusted by the browser, so if you are having people use the application you need to get a real SSL certificate from a certificate provider, like Godaddy or many others. For testing purposes you can make a “self-signed” certificate which can be used, but the client using the browser will get warnings indicating problems with the certificate.
There is no way to get a real SSL certificate for free.
I trust from this answer you can make the appropriate google queries to get you on your way.
