How to enable WSS

How to enable WSS support

In order to create a secure channel, you have to provide the server with a certificate. Once this is done, you should be able to start the server as normal.

The following code is taken from a Java-Websocket example: https://github.com/TooTallNate/Java-WebSocket/blob/master/src/main/example/SSLServerExample.java

// load up the key store String STORETYPE = "JKS"; String KEYSTORE = "keystore.jks"; String STOREPASSWORD = "storepassword"; String KEYPASSWORD = "keypassword";

KeyStore ks = KeyStore.getInstance( STORETYPE ); File kf = new File( KEYSTORE ); ks.load( new FileInputStream( kf ), STOREPASSWORD.toCharArray() );

KeyManagerFactory kmf = KeyManagerFactory.getInstance( "SunX509" ); kmf.init( ks, KEYPASSWORD.toCharArray() ); TrustManagerFactory tmf = TrustManagerFactory.getInstance( "SunX509" ); tmf.init( ks );

SSLContext sslContext = null; sslContext = SSLContext.getInstance( "TLS" ); sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null );

Once you have the certificate as a SSLContext, you can enable WSS.

I have modified the default example code to demonstrate (hightlighting the changed part with bold) ` server = new JSONServer(core); server.enableWSS(sslContext) server.open("localhost", 8887, new ServerEvents() {

@Override public void newSession(UUID sessionIndex, SessionInformation information) { // sessionIndex is used to send messages. System.out.println("New session " + sessionIndex + ": " + information.getIdentifier()); }

@Override public void lostSession(UUID sessionIndex) { } }); `
