Chapter 2: Secure TCP Socket Connections

Code sample – TcpService

// Create new TCP service

TcpService TCP= new TcpService();

// enable debug

TCP.setDebugEnabled(true);

// Declare security for connection with secure clients.

// Keystore info need to be changed to custom values.

SSLStoreObject oKeyStore = new SSLStoreObject("keystore.txt");

oKeyStore.setPassword("password", false);

// Declare trust for clients authorized to connect

// truststore info need to be changed to custom values.

SSLStoreObject oTrustStore = new SSLStoreObject("truststore.txt");

oTrustStore.setPassword("trustword",false);

// Set security key and trust for server

TCP.setServerSecurity(oKeyStore,oTrustStore);

TCP.setServerSecurityEnabled(true);

// Set the server TCP Port to listen for client connections.

// Warning, for secured clients, always use setServerInfo()

// After setServerSecurity() and setServerSecurityEnabled() , otherwise,

// The server will start listening for standard connections instead.

// In this sample, the server will listen for secured connections on port 10000

// At this time the server will bound its socket on the specified port. TCP.setServerInfo(10000, 0);

// Set the target TCP port to forward data to.

// In this sample the server forwards data to standard connections on port 9999

// Target can be secured using setTargetSecurity(oTrustStore)

TCP.setTargetSecurityEnabled(false);

TCP.setTargetInfo("polaris",9999);

// Start the server on blocking mode (default)

TCP.startServer();

// Stop the server.

TCP.stopServer();
