Configuring HTTPS

Play can configured to serve HTTPS. To enable this, simply tell Play which port to listen using the https.port system property. For example:

./start -Dhttps.port=9443

SSL Certificates

By default, Play will generate itself a self signed certificate, however typically this will not be suitable for serving a website. Play uses Java key stores to configure SSL certificates and keys.

Signing authorities often provide instructions on how to create a Java keystore (typically with reference to Tomcat configuration). The official Oracle documentation on how to generate keystores using the JDK keytool utility can be found here.

Having created your keystore, the following system properties can be used to configure Play to use it:

Turning HTTP off

To disable binding on the HTTP port, set the http.port system property to be disabled, eg:

./start -Dhttp.port=disabled -Dhttps.port=9443 -Dhttps.keyStore=/path/to/keystore -Dhttps.keyStorePassword=changeme
