Decrypting data from a secure socket
- by Ronald
I'm working on a server application in Java. I've successfully got past the handshake portion of the communication process, but how do I go about decrypting my input stream? Here is how I set up my server:
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.HashMap;
import javax.net.ServerSocketFactory;
import javax.net.ssl.SSLServerSocket;
import javax.net.ssl.SSLServerSocketFactory;
import org.json.me.JSONException;
import dictionary.Dictionary;
public class Server {
private static int port = 1234;
public static void main(String[] args) throws JSONException {
System.setProperty("javax.net.ssl.keyStore", "src/my.keystore");
System.setProperty("javax.net.ssl.keyStorePassword", "test123");
System.out.println("Starting server on port: " + port);
HashMap<String, Game> games = new HashMap<String, Game>();
final String[] enabledCipherSuites = { "SSL_RSA_WITH_RC4_128_SHA" };
try{
SSLServerSocketFactory socketFactory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
SSLServerSocket listener = (SSLServerSocket) socketFactory.createServerSocket(port);
listener.setEnabledCipherSuites(enabledCipherSuites);
Socket server;
Dictionary dict = new Dictionary();
Game game = new Game(dict); //for testing, creates 1 global game.
while(true){
server = listener.accept();
ClientConnection conn = new ClientConnection(server, game, "User");
Thread t = new Thread(conn);
t.start();
}
}
catch(IOException e){
System.out.println("Failed setting up on port: " + port);
e.printStackTrace();
}
}
}
I used a BufferedReader to get the data send from the client:
BufferedReader d = new BufferedReader(new InputStreamReader(socket.getInputStream()));
After the handshake is complete it appears like I'm getting encrypted data. I did some research online and it seems like I might need to use a Cipher, but I'm not sure. Any ideas?
