I have an Android client and a Java Server that communicate with a SSL socket. The communication works well with an Android version < 6.0. With Android 6.0 I have this exception:
javax.net.ssl.SSLHandshakeException: no cipher suites in common

This is my server code:
ServerSocket server = null;
Socket socket=null;
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
try{
char[] passphrase = "password".toCharArray();
String keyfile = "keyName";
ctx = SSLContext.getInstance("TLS");
kmf = KeyManagerFactory.getInstance("SunX509");
ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream(keyfile), passphrase);
kmf.init(ks, passphrase);
ctx.init(kmf.getKeyManagers(), null, null);
ServerSocketFactory ssf = ctx.getServerSocketFactory();
server = ssf.createServerSocket(port);
}catch (IOException e){
e.printStackTrace();
}
while (true) {
socket = server.accept();
new Thread(new WorkerThread(socket));
}
This is my Android code:
Socket clientSocket = null;
KeyStore store = KeyStore.getInstance("BKS");
InputStream in2 = ctx.getResources().openRawResource(
R.raw.server);
store.load(in2, "password".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory
.getInstance(KeyManagerFactory.getDefaultAlgorithm());
tmf.init(store);
SSLContext sslcontext = SSLContext.getInstance("SSL");
sslcontext.init(null, tmf.getTrustManagers(),
new SecureRandom());
SSLSocketFactory sslsocketfactory = sslcontext
.getSocketFactory();
clientSocket = (SSLSocket) sslsocketfactory.createSocket(
Constants.SERVER_HOST, port);
ObjectInputStream obi = new ObjectInputStream(
clientSocket.getInputStream());
ObjectOutputStream obs = new ObjectOutputStream(
clientSocket.getOutputStream());
obs.writeObject("text");
obs.flush();
I have also tried to set the cipher suite but without result.
