在Android上实现SSL握手(客户端需要密钥和证书),实现服务器和客户端之间Socket交互
Android的私钥和信任证书的格式必须是BKS格式的,通过配置本地JDK,让keytool可以生成BKS格式的私钥和信任证书,java本身没有BouncyCastle密库
服务端:
Java代码
- public class SSLServer {
- private static final int SERVER_PORT = 50030;
- private static final String SERVER_KEY_PASSWORD = "123456";
- private static final String SERVER_AGREEMENT = "TLS";//使用协议
- private static final String SERVER_KEY_MANAGER = "SunX509";//密钥管理器
- private static final String SERVER_KEY_KEYSTORE = "JKS";//密库,这里用的是Java自带密库
- private static final String SERVER_KEYSTORE_PATH = "src/data/kserver.keystore";//密库路径
- private SSLServerSocket serverSocket;
- public static void main(String[] args) {
- SSLServer server = new SSLServer();
- server.init();
- server.start();
- }
- //由于该程序不是演示Socket监听,所以简单采用单线程形式,并且仅仅接受客户端的消息,并且返回客户端指定消息
- public void start() {
- if (serverSocket == null) {
- System.out.println("ERROR");
- return;
- }
- while (true) {
- try {
- System.out.println("Server Side......");
- Socket s = serverSocket.accept();
- InputStream input = s.getInputStream();
- OutputStream output = s.getOutputStream();
- BufferedInputStream bis = new BufferedInputStream(input);
- BufferedOutputStream bos = new BufferedOutputStream(output);
- byte[] buffer = new byte[20];
- bis.read(buffer);
- System.out.println(new String(buffer));
- bos.write("This is Server".getBytes());
- bos.flush();
- s.close();
- } catch (Exception e) {
- System.out.println(e);
- }
- }
- }
- public void init() {
- try {
- //取得SSLContext
- SSLContext ctx = SSLContext.getInstance(SERVER_AGREEMENT);
- //取得SunX509私钥管理器
- KeyManagerFactory kmf = KeyManagerFactory.getInstance(SERVER_KEY_MANAGER);
- //取得JKS密库实例
- KeyStore ks = KeyStore.getInstance(SERVER_KEY_KEYSTORE);
- //加载服务端私钥
- ks.load(new FileInputStream(SERVER_KEYSTORE_PATH), SERVER_KEY_PASSWORD.toCharArray());
- //初始化
- kmf.init(ks, SERVER_KEY_PASSWORD.toCharArray());
- //初始化SSLContext
- ctx.init(kmf.getKeyManagers(),null, null);
- //通过SSLContext取得ServerSocketFactory,创建ServerSocket
- serverSocket = (SSLServerSocket) ctx.getServerSocketFactory().createServerSocket(SERVER_PORT);
- } catch (Exception e) {
- System.out.println(e);
- }
- }
- }
客户端:
Java代码
- public class MySSLSocket extends Activity {
- private static final int SERVER_PORT = 50030;//端口号
- private static final String SERVER_IP = "218.206.176.146";//连接IP
- private static final String CLIENT_KET_PASSWORD = "123456";//私钥密码
- private static final String CLIENT_TRUST_PASSWORD = "123456";//信任证书密码
- private static final String CLIENT_AGREEMENT = "TLS";//使用协议
- private static final String CLIENT_KEY_MANAGER = "X509";//密钥管理器
- private static final String CLIENT_TRUST_MANAGER = "X509";//
- private static final String CLIENT_KEY_KEYSTORE = "BKS";//密库,这里用的是BouncyCastle密库
- private static final String CLIENT_TRUST_KEYSTORE = "BKS";//
- private static final String ENCONDING = "utf-8";//字符集
- private SSLSocket Client_sslSocket;
- private Log tag;
- private TextView tv;
- private Button btn;
- private Button btn2;
- private Button btn3;
- private EditText et;
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);

- btn2 = (Button) findViewById(R.id.Button02);
- btn3 = (Button) findViewById(R.id.Button03);
- btn.setOnClickListener(new Button.OnClickListener(){
- @Override
- public void onClick(View arg0) {
- if(null != Client_sslSocket){
- getOut(Client_sslSocket, et.getText().toString());
- getIn(Client_sslSocket);
- et.setText("");
- }
- }
- });
- btn2.setOnClickListener(new Button.OnClickListener(){
- @Override
- public void onClick(View arg0) {
- try {
- Client_sslSocket.close();
- Client_sslSocket = null;
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- });
- btn3.setOnClickListener(new View.OnClickListener(){
- @Override
- public void onClick(View arg0) {
- init();
- getIn(Client_sslSocket);
- }
- });
- }
- public void init() {
- try {
- //取得SSL的SSLContext实例
- SSLContext sslContext = SSLContext.getInstance(CLIENT_AGREEMENT);
- //取得KeyManagerFactory和TrustManagerFactory的X509密钥管理器实例
- KeyManagerFactory keyManager = KeyManagerFactory.getInstance(CLIENT_KEY_MANAGER);
- TrustManagerFactory trustManager = TrustManagerFactory.getInstance(CLIENT_TRUST_MANAGER);
- //取得BKS密库实例
- KeyStore kks= KeyStore.getInstance(CLIENT_KEY_KEYSTORE);
- KeyStore tks = KeyStore.getInstance(CLIENT_TRUST_KEYSTORE);
- //加客户端载证书和私钥,通过读取资源文件的方式读取密钥和信任证书
- kks.load(getBaseContext()
- .getResources()
- .openRawResource(R.drawable.kclient),CLIENT_KET_PASSWORD.toCharArray());
- tks.load(getBaseContext()
- .getResources()
- .openRawResource(R.drawable.lt_client),CLIENT_TRUST_PASSWORD.toCharArray());
- //初始化密钥管理器
- keyManager.init(kks,CLIENT_KET_PASSWORD.toCharArray());
- trustManager.init(tks);
- //初始化SSLContext
- sslContext.init(keyManager.getKeyManagers(),trustManager.getTrustManagers(),null);
- //生成SSLSocket
- Client_sslSocket = (SSLSocket) sslContext.getSocketFactory().createSocket(SERVER_IP,SERVER_PORT);
- } catch (Exception e) {
- tag.e("MySSLSocket",e.getMessage());
- }
- }
- public void getOut(SSLSocket socket,String message){
- PrintWriter out;
- try {
- out = new PrintWriter(
- new BufferedWriter(
- new OutputStreamWriter(
- socket.getOutputStream()
- )
- ),true);
- out.println(message);
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- public void getIn(SSLSocket socket){
- BufferedReader in = null;
- String str = null;
- try {
- in = new BufferedReader(
- new InputStreamReader(
- socket.getInputStream()));
- str = new String(in.readLine().getBytes(),ENCONDING);
- } catch (UnsupportedEncodingException e) {
- e.printStackTrace();
- } catch (IOException e) {
- e.printStackTrace();
- }
- new AlertDialog
- .Builder(MySSLSocket.this)
- .setTitle("服务器消息")
- .setNegativeButton("确定", null)
- .setIcon(android.R.drawable.ic_menu_agenda)
- .setMessage(str)
- .show();
- }
- }
