If you run beetRoot as a standalone server and you want to run it with the HTTPS protocol, there's a prepared and self-signed keystore file: ssl/beetroot.jks that is valid forever.
To do so switch the configuration parameter ws_https to 'yes' and use this default keystore file which is specified by the configuration parameter keystore.
Your browser will still complain, because it is not issued by a valid Certificate Authority (CA), but you can force the browser to still load the web-app by adding this exception. If you run beetRoot in productive mode, you have to acquire a valid certificate and store it in the keystore file or in a an own; Java supports the PKCS#12 format and Java keystore files can be opened with tools such as this one: https://keystore-explorer.org.
The password for ssl/beetroot.jks is beetroot.
