how to do ssl socket programming

我正在通过Socket使用无线路由器从android作为客户端和笔记本电脑作为服务器进行通信。但是如果我想如何安全地进行通信。这是我在eclipse中的android代码

public class TCPClient implements Runnable {

    public void run() {

     try {

         InetAddress serverAddr = InetAddress.getByName("192.168.1.2");

             Log.d("TCP", "C: Connecting...");

             Socket socket = new Socket(serverAddr,12345);

             String message = "Hello from Client android emulator";
              try {

                     Log.d("TCP", "C: Sending: '" + message + "'");

                     PrintWriter out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())),true);

                     out.println(message);

                     Log.d("TCP", "C: Sent.");

                 Log.d("TCP", "C: Done.");



         } catch(Exception e) {

             Log.e("TCP", "S: Error", e);
                 } finally {

                    socket.close();

                  }
     } catch (Exception e) {

          Log.e("TCP", "C: Error", e);

     }

}

}

这是Netbean中的服务器代码，它正在与android进行通信。我必须做些什么改变？

public class TCPDesktopServer implements Runnable{



public static final String SERVERIP = "10.0.2.15";

public static final int SERVERPORT = 12345;



public void run() {

     try {

        System.out.println("S: Connecting...");

        ServerSocket serverSocket = new ServerSocket(SERVERPORT);

         while (true) {

             Socket client = serverSocket.accept();

             System.out.println("S: Receiving...");

             try {
                  BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));

                  String str = in.readLine();

                  System.out.println("S: Received: '" + str + "'");
             } catch(Exception e) {

                    System.out.println("S: Error");

                    e.printStackTrace();

             } finally {
                    client.close();
                    System.out.println("S: Done.");
                }
         }

     } catch (Exception e) {

         System.out.println("S: Error");

         e.printStackTrace();
     }
}

public static void main (String a[]) {

    Thread desktopServerThread = new Thread(new TCPDesktopServer());

    desktopServerThread.start();

}

}

Answer 1

好像你需要使用javax.crypto.CipherOutputStream / CipherInputStream，或者如果你想要一个更标准化的方法，你可以尝试Apache commons（http://commons.apache.org/），其中有一个基本的SSL实现。

Answer 2

您可以非常轻松地使用SSLSocket类，它是基本java发行版的一部分。如果您在获取证书时遇到问题，可以使用this教程向您展示如何允许自签名证书和不匹配的主机名。
