Я разрабатываю Android приложение для уровня API 16+ и от того, что я видел по умолчанию TLS v1.1 и TLS v1.2 поддерживаются, но не включена на Android 4.1+Android 4.2.2, Как включить TLS 1.2 для HttpsURLConnection?
Я использовал SSLSocketFacory здесь :
http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/
Что я сумел получить работу на следующем примере:
public class TLSSocketFactory extends SSLSocketFactory {
private SSLSocketFactory internalSSLSocketFactory;
public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
internalSSLSocketFactory = context.getSocketFactory();
}
@Override
public String[] getDefaultCipherSuites() {
return internalSSLSocketFactory.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return internalSSLSocketFactory.getSupportedCipherSuites();
}
public Socket createSocket() throws IOException{
return enableTLSOnSocket(internalSSLSocketFactory.createSocket());
}
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
}
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
}
@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
}
private Socket enableTLSOnSocket(Socket socket) {
if(socket != null && (socket instanceof SSLSocket)) {
((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
}
return socket;
}
}
и я использую следующий назвать:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try{
SSLContext context = SSLContext.getDefault();
TLSSocketFactory factory = new TLSSocketFactory();
SSLSocket socket = (SSLSocket)factory.createSocket();
String[] protocols = socket.getSupportedProtocols();
// this now has the correct protocols enabled for sockets
String[] enabled = socket.getEnabledProtocols();
HttpsURLConnection.setDefaultSSLSocketFactory(new TLSSocketFactory());
URL url = new URL("https://mysslsite/");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setSSLSocketFactory(new TLSSocketFactory());
Log.i("", "");
}catch(Exception ex){
ex.printStackTrace();
}
}
}
Я вижу соединение сокета. Теперь у меня есть правильные разрешенные протоколы, однако как включить эти протоколы для соединения с URL? как бы я также проверить, что эти протоколы были включены для HttpsURLConnection?
Я попытался установить фабрику сокетов ssl для подключения, но я не уверен, как проверить, что протоколы были включены?
UPDATE: Я изменил свой код следующим образом:
String myURL = "https://mysslservice";
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(null, null, null);
SSLSocketFactory noSSLv3Factory = new NoSSLv3SocketFactory(sslcontext.getSocketFactory());
HttpsURLConnection.setDefaultSSLSocketFactory(noSSLv3Factory);
URL url = new URL(myURL);
HttpsURLConnection l_connection = (HttpsURLConnection) url.openConnection();
l_connection.connect();
Я использовал следующую реализацию SSL завода
общественного класса NoSSLv3SocketFactory расширяет SSLSocketFactory { частный окончательный SSLSocketFactory делегат;
public NoSSLv3SocketFactory() {
this.delegate = HttpsURLConnection.getDefaultSSLSocketFactory();
}
public NoSSLv3SocketFactory(SSLSocketFactory delegate) {
this.delegate = delegate;
}
@Override
public String[] getDefaultCipherSuites() {
return delegate.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return delegate.getSupportedCipherSuites();
}
private Socket makeSocketSafe(Socket socket) {
if (socket instanceof SSLSocket) {
socket = new NoSSLv3SSLSocket((SSLSocket) socket);
}
return socket;
}
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
return makeSocketSafe(delegate.createSocket(s, host, port, autoClose));
}

if (enabledProtocols.size() > 1) {
enabledProtocols.remove("SSLv3");
System.out.println("Removed SSLv3 from enabled protocols");
} else {
System.out.println("SSL stuck with protocol available for " + String.valueOf(enabledProtocols));
}
protocols = enabledProtocols.toArray(new String[enabledProtocols.size()]);
}

однако я получаю следующее исключение:

служба SSL имеет только TLSv1.2 Enabl ed и SSLv3 отключен, однако, похоже, приложение все еще использует sslv3?
