I am trying to send data from my client to my server. Therefore I am using TSL.
I created the certificates and these are loaded without any troubles.
The connection is established, but the handshake between the client and the server is never called, and the handshakeCompleted is never called.
Client:
char[] password = "Password".toCharArray();
KeyStore trustStore = KeyStore.getInstance("BKS");
trustStore.load(activity.getResources().openRawResource(R.raw.truststore), password);
Log.i("Update", "Loaded trust certificate");
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(trustStore);
Log.i("Update", "Loaded trustManagerFactory");
KeyStore keyStore = KeyStore.getInstance("BKS");
keyStore.load(activity.getResources().openRawResource(R.raw.keystore), password);
Log.i("Update", "Loaded key certificate");
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, password);
Log.i("Update", "Loaded keyManagerFactory");
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), null);
Log.i("Update", "Loaded SSLContext");
SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
final SSLSocket socket = (SSLSocket) sslSocketFactory.createSocket(InetAddress.getByName(host), port);
Log.i("Update", "Loaded SSL
socket.addHandshakeCompletedListener(new HandshakeCompletedListener(){
#Override
public void handshakeCompleted(HandshakeCompletedEvent handshakeCompletedEvent){
try{
Log.i("Update", "Did handshake");
writer = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));
Log.i("Update", "Writer");
reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
Log.i("Update", "Reader");
while(isRunning){
try{
writer.println("Test");
writer.flush();
Log.i("DATA", "DATA SENT");
}catch(Exception e){
e.printStackTrace();
}
}
writer.close();
reader.close();
socket.close();
}catch(Exception e){
e.printStackTrace();
}
}
});
socket.startHandshake();
Server:
char[] password = "Password".toCharArray();
KeyStore keyStore = KeyStore.getInstance("JKS");
keyStore.load(getClass().getResourceAsStream("/security/keystore.jks"), password);
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, password);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagerFactory.getKeyManagers(), null, null);
SSLServerSocketFactory sslServerSocketFactory = sslContext.getServerSocketFactory();
SSLServerSocket serverSocket = (SSLServerSocket) sslServerSocketFactory.createServerSocket(7826);
System.out.println("Accepting connections now...");
while(true){
SSLSocket socket = (SSLSocket) serverSocket.accept();
socket.setUseClientMode(false);
socket.addHandshakeCompletedListener(handshakeCompletedEvent -> {
try{
reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
writer = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));
while(running){
if(!socket.isConnected() || socket.isClosed()){
disconnect();
return;
}
for(Iterator<String> pendingIterator = pendingMessages.iterator(); pendingIterator.hasNext();){
String message = pendingIterator.next();
pendingIterator.remove();
writer.println(message); writer.flush();
}
//Auto decrypt when message arrives, but no thread blocking
if(reader.ready()){
String line = reader.readLine();
System.out.println(line);
}
}
}catch(Exception e){
e.printStackTrace();
}
});
socket.startHandshake();
}
As you can see I am waiting on both sides for the handshakeComplete, using it only on the client or only on the server side doesn't work either

Hello i'm trying to run a SSL server and client program. I'm first creating a certificate with the cmd command "keytool -genkey -keystore mySrvKeyStore -keyalg RSA". 123456 is the password after i fill in the info.

Please help me, what is the problem?
The error is in these two lines:
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.getServerSocketFactory();
Why does it throw this Exception? Method getServerSocketFactory() states:
Throws:
IllegalStateException - if the SSLContextImpl requires initialization and the init() has not been called
In the client, you do indeed call ctx.init(kmf.getKeyManagers(), null, null); before you call ctx.getServerSocketFactory();
But in the server you do not call this - you only initialise the KeyManagerFactory.
Im trying to connect a client to a server via SSL secure connection, but I seem to be thrown the "SSLHandshakeExceptin: no cipher suites in common" everytime. I could really use some help with this one.
Here is the server code:
public ChatServer() {
usedNames.add("arnold");
SSLServerSocket ss = null;
try {
SecureRandom sr = new SecureRandom();
String passphrase = "serverpwd";
//read a file with client certificates
KeyStore clientKeyStore = KeyStore.getInstance("JKS");
clientKeyStore.load(new FileInputStream("client.public"), "public".toCharArray());
//reads a file with servers certificate and secret key
KeyStore serverKeyStore = KeyStore.getInstance("JKS");
serverKeyStore.load(new FileInputStream("server.private"), passphrase.toCharArray());
// tmf,kmf and sslContext
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(clientKeyStore);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(serverKeyStore, passphrase.toCharArray());
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), sr);
// Create socket
SSLServerSocketFactory factory = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
ss = (SSLServerSocket) factory.createServerSocket(serverPort);
ss.setNeedClientAuth(true); // client needs to have auth.
ss.setEnabledCipherSuites(new String[]{"TLS_RSA_WITH_AES_128_CBC_SHA"});
} catch (Exception e) {
System.err.println("[system] could not create socket on port " + this.serverPort);
e.printStackTrace(System.err);
System.exit(1);
}
// start listening for new connections
System.out.println("[system] listening ...");
try {
while (true) {
Socket socket = ss.accept(); // connection established
((SSLSocket)socket).startHandshake(); //explicitly trigger SSL handshake
String username = ((SSLSocket) socket).getSession().getPeerPrincipal().getName();
And here is the client code:
SecureRandom sr = new SecureRandom();
KeyStore serverKeyStore = KeyStore.getInstance("JKS");
serverKeyStore.load(new FileInputStream("server.public"), "public".toCharArray());
KeyStore clientKeyStore = KeyStore.getInstance("JKS");
clientKeyStore.load(new FileInputStream(sslPrivate), passphrase.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
tmf.init(serverKeyStore);
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(clientKeyStore, passphrase.toCharArray());
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), sr);
// create socket
SSLSocketFactory sf = sslContext.getSocketFactory();
socket = (SSLSocket)sf.createSocket("localhost", serverPort);
socket.setEnabledCipherSuites(new String[] { "TLS_RSA_WITH_AES_128_CBC_SHA" }); //(CipherSuite)
socket.startHandshake(); // //explicitly trigger SSL handshake
This is what prints out on the console where i run the "server":
And this is on the console where i run the "client":
Am trying to establish an SSL Connection between a client and a server. But anytime time i try to connect from my client, i get a javax.net.ssl.SSLHandshakeException: no cipher suites in common no cipher suites in common error on my server.

can someone please tell me what am doing wrong?
You will have to use SSLContext for this purpose. Check out the sample code which I implemented in one of my applications below. Client context means you become the client and call some back end. Server context means you accept the client requests.
public class SSLUtil {
private static String KEY_STORE_TYPE = "JKS";
private static String TRUST_STORE_TYPE = "JKS";
private static String KEY_MANAGER_TYPE = "SunX509";
private static String TRUST_MANAGER_TYPE = "SunX509";
private static String PROTOCOL = "TLS";
private static SSLContext serverSSLCtx = null;
private static SSLContext clientSSLCtx = null;
public static SSLContext createServerSSLContext(final String keyStoreLocation,
final String keyStorePwd)
throws KeyStoreException,
NoSuchAlgorithmException,
CertificateException,
FileNotFoundException,
IOException,
UnrecoverableKeyException,
KeyManagementException {
if (serverSSLCtx == null) {
KeyStore keyStore = KeyStore.getInstance(KEY_STORE_TYPE);
keyStore.load(new FileInputStream(keyStoreLocation), keyStorePwd.toCharArray());
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KEY_MANAGER_TYPE);
keyManagerFactory.init(keyStore, keyStorePwd.toCharArray());
serverSSLCtx = SSLContext.getInstance(PROTOCOL);
serverSSLCtx.init(keyManagerFactory.getKeyManagers(), null, null);
}
return serverSSLCtx;
}
public static SSLContext createClientSSLContext(final String trustStoreLocation,
final String trustStorePwd)
throws KeyStoreException,
NoSuchAlgorithmException,
CertificateException,
FileNotFoundException,
IOException,
KeyManagementException {
if (clientSSLCtx == null) {
KeyStore trustStore = KeyStore.getInstance(TRUST_STORE_TYPE);
trustStore.load(new FileInputStream(trustStoreLocation), trustStorePwd.toCharArray());
TrustManagerFactory trustManagerFactory =
TrustManagerFactory.getInstance(TRUST_MANAGER_TYPE);
trustManagerFactory.init(trustStore);
clientSSLCtx = SSLContext.getInstance(PROTOCOL);
clientSSLCtx.init(null, trustManagerFactory.getTrustManagers(), null);
}
return clientSSLCtx;
}
}
Finally make sure you import the trusted server certificate to the client key store. Literally server and client should have different key stores. The key store used in the client side is referred to as client trust store since we are trusting the server certificate here. This article may help.
I'm trying to establish a SSL Connection between an IPhone App and an Java SSLServerSocket.
My Java Server looks like that:
SSLServerSocketFactory ssf = null;
try {
// set up key manager to do server authentication
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
char[] passphrase = "passphrase".toCharArray();
ctx = SSLContext.getInstance("TLS");
kmf = KeyManagerFactory.getInstance("SunX509");
ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream("fsKeystore"), passphrase);
kmf.init(ks, passphrase);
ctx.init(kmf.getKeyManagers(), null, null);
ssf = ctx.getServerSocketFactory();
System.out.println("Waiting for Connection");
SSLServerSocket sslsocketServer = (SSLServerSocket) ssf.createServerSocket(9999);
SSLSocket sslsocket = (SSLSocket) sslsocketServer.accept();
sslsocket.addHandshakeCompletedListener(new HandshakeCompletedListener() {
#Override
public void handshakeCompleted(HandshakeCompletedEvent arg0) {
System.out.println("Handshake finished");
}
});
InputStream inputstream = sslsocket.getInputStream();
InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
BufferedReader bufferedreader;
bufferedreader = new BufferedReader(inputstreamreader);
String string = "";
while ((string = bufferedreader.readLine()) != null) {
string = bufferedreader.readLine();
System.out.println(System.currentTimeMillis());
System.out.println(string);
System.out.flush();
}
} catch (Exception e) {
e.printStackTrace();
}
In Objective-c I have implemented this solution:
-(id) initWithUrl: (NSString*) host onPort: (NSInteger) port withDelegate:(id<TCPDelegate>) delegate{
self = [super init];
if(self){
//initTimer
sendBuffer=[[NSMutableArray alloc]init];
NSTimer *timer =[NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:#selector(timerTick:) userInfo:nil repeats:YES];
NSRunLoop *runloop = [NSRunLoop currentRunLoop];
[runloop addTimer:timer forMode:NSDefaultRunLoopMode];
del=delegate;
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL,(__bridge CFStringRef)host, port,&readStream,&writeStream);
iStream = (__bridge_transfer NSInputStream *)readStream;
oStream = (__bridge_transfer NSOutputStream *)writeStream;
[iStream setDelegate:self];
[oStream setDelegate:self];
[iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[oStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[iStream open];
[oStream open];
[iStream setProperty:NSStreamSocketSecurityLevelNegotiatedSSL
forKey:NSStreamSocketSecurityLevelKey];
[oStream setProperty:NSStreamSocketSecurityLevelNegotiatedSSL
forKey:NSStreamSocketSecurityLevelKey];
line = #"";
}
return self;
}
in the Iphone App I get
CFNetwork SSLHandshake failed (-9807)
Any Idea what the problem might be?
You may want to investigate using NSURLConnection. It has a delegate that you can use for authentication challenges.
