How do I get SSL for my domains?
OpenShift includes support for Server Name Identification, which improves support for TLS by sending your OpenShift-configured domain alias as a part of the handshake. Support for enabling HTTPS connections to custom, aliased hostnames is available for users of OpenShift Online's Bronze and Silver plans.
If you are still getting by on OpenShift Online's generous Free plan, you'll see a warning message at the top of your application's SSL configuration area. You can always take advantage of our *.rhcloud.com wildcard certificate in order to securely connect to any application via it's original, OpenShift-provided hostname URL.
