SSL java服务器与android客户端连接失败

Question

I am trying to setup mutual authentication SSL connection between java host and android client. Don't know why its not getting connected. Below are the code of Android client app and Java server.

Client code:

private SSLContext createSSLContext(final Context cont){
    SSLContext ssl_cont = null;
    try {
        Log.d(TAG, "TrustStore - Initializing");   
        KeyStore trustStore = KeyStore.getInstance("BKS");
        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        InputStream trustStoreStream = cont.getResources().openRawResource(R.raw.myclienttruststore);
        trustStore.load(trustStoreStream, "client".toCharArray());
        trustManagerFactory.init(trustStore);
        Log.d(TAG, "TrustStore - Initialized");

        // Setup keystore
        Log.d(TAG, "KeyStore - Initializing");
        KeyStore keyStore = KeyStore.getInstance("BKS");
        KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        InputStream keyStoreStream = cont.getResources().openRawResource(R.raw.myclient);
        keyStore.load(keyStoreStream, "client".toCharArray());
        keyManagerFactory.init(keyStore, "client".toCharArray());
        Log.d(TAG, "KeyStore - Initialized");

        ssl_cont = SSLContext.getInstance("TLS");
        ssl_cont.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), null); 
    } catch (Exception e) {
        // TODO Auto-generated catch block
        alertbox("SSLClient", "ERROR: " + e.getMessage());
        Log.d(TAG, "ERROR: " + e.getMessage());
    }
    return ssl_cont;
}

OnClickListener onConnClick = new OnClickListener() {

    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        try {
            // Setup the SSL context to use the truststore and keystore
            Log.d(TAG, "Started..");
            SSLContext ssl_context = createSSLContext(cont);
            Log.d(TAG,"here 1...");
            SSLSocketFactory socketFactory = (SSLSocketFactory) ssl_context.getSocketFactory();
            Log.d(TAG,"here 2...");
            socket = (SSLSocket) socketFactory.createSocket(ipadd.getText().toString().trim(), Integer.parseInt(port.getText().toString().trim()));
            Log.d(TAG,"here 3...");
            dataOut = new DataOutputStream(socket.getOutputStream());
            dataIn = new DataInputStream(socket.getInputStream());
            dataOut.writeUTF("Hello !!");
            msgin.setText("Connected");
            Log.d(TAG, "Completed..");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            msgin.setText("Not connected");
            alertbox("Main", "ERROR: " + e.getMessage());
            Log.d(TAG, "ERROR: " + e.getMessage());
        }
    }
};

Server code:

    try {
        mySSLServerFac = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
        mySSLServerSocket = (SSLServerSocket) mySSLServerFac.createServerSocket(9999);
        System.out.println("Listening on 9999\n");
        mySSLSocket = (SSLSocket) mySSLServerSocket.accept();           
        DataInputStream input = new DataInputStream(mySSLSocket.getInputStream());
        DataOutputStream output = new DataOutputStream(mySSLSocket.getOutputStream());      
        do{
            System.out.println("Remote IP Address : " + mySSLSocket.getInetAddress());
            msg = input.readUTF().toString();
            System.out.println(msg);
            java.util.Scanner sc = new java.util.Scanner(System.in);
            output.writeUTF(sc.nextLine());
        }while(msg != "exit");
        System.out.println(msg);                
    } catch (Exception e) {
        e.printStackTrace();
    }

I am stuck with "No cipher suites in common" error at server. Since i am nowhere in SSL connection setup. Let me help if you find out the bug or major problem.

Here is the link i followed to create certificate and truststore. Truststore and kestore i have created are here

I am using Android 2.2 and BKSProvider 1.46, please let know where i am going wrong. I have to wind up this project as soon as possible.

Thanks in advance.

Answer 1

From the stack trace it looks like exception you caught does not contain a message.

Log.d(TAG, e.getMessage());

It has nothing to do with SSL.

Answer 2

It's solved, Problem was with the truststore of java host, followed this post.

The trustStore needs to be specified for client/server as they are using the default trustStore, causing failure. Using -Djavax.net.ssl.trustStore=servertruststore.jks -Djavax.net.ssl.trustStorePassword=server on the server and creating own keystore & truststore at client allows the session to complete. It was the -Djavax.net.debug=ssl,handshake which helped lot.

The entire command is: java -Djavax.net.ssl.keyStore=server.jks -Djavax.net.ssl.keyStorePassword=server -Djavax.net.ssl.trustStore=servertruststore.jks -Djavax.net.ssl.trustStorePassword=server SSLServer

Now i am on to creating sslsession and multi-threaded programming.
