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);
setContentView(R.layout.main);
tv = (TextView) findViewById(R.id.TextView01);
et = (EditText) findViewById(R.id.EditText01);
btn = (Button) findViewById(R.id.Button01);
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();
}
}
