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);
- }
- }
- }

- 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";//
