             * Uncomment the Connector below
             * Execute:
                 %JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)
                 $JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA  (Unix)
               with a password value of "changeit" for both the certificate and the keystore itself.
             * Restart and visit https://localhost:8443/
