I am trying to display the date on an HTTPS website via an SSL server.
I am getting an error thrown on line 31 (I have marked where it is).
I reckon it might be to do with the browser and how it is set up. Since the error is coming from an unsupported message.

I'm trying to write a simple ssl server socket and client socket program. first i get some real certificate and then i used the first code to generate keystore for it. then i wrote server and client code so my server use that keystore as server certificate but no certificate sent during connection and session.getLocalCertificates() only return null
my keystore generating code:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.security.KeyStore;
import java.security.cert.CertPath;
import java.security.cert.Certificate;
import java.security.cert.CertificateFactory;
import java.security.cert.X509Certificate;
import java.util.ArrayList;
import java.util.List;
public class MainClass {
public static void main(String args[]) throws Exception {
CertificateFactory cf = CertificateFactory.getInstance("X.509");
List mylist = new ArrayList();
FileInputStream in = new FileInputStream("C:\\Users\\nima\\Downloads\\72315359_example.com.cert");
Certificate cr = cf.generateCertificate(in);
mylist.add(cr);
CertPath cp = cf.generateCertPath(mylist);
System.out.println(cp);
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(null, null);
List cplist = cp.getCertificates();
Object[] o = cplist.toArray();
for (int i = 0; i < o.length; i++) {
X509Certificate c = (X509Certificate) o[i];
ks.setCertificateEntry("my" + i, c);
}
FileOutputStream output = new FileOutputStream("C:\\Users\\nima\\Downloads\\test.dat");
ks.store(output, "mypass".toCharArray());
output.close();
}
}
my server code:
import java.io.PrintStream;
import java.math.BigInteger;
import java.net.ServerSocket;
import java.net.Socket;
import java.security.cert.Certificate;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLServerSocketFactory;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocket;
public class MainClass {
public static void main(String args[]) throws Exception {
System.setProperty("javax.net.ssl.keyStore", "C:\\Users\\nima\\Downloads\\test.dat");
System.setProperty("javax.net.ssl.keyStorePassword", "mypass");
SSLServerSocketFactory ssf = (SSLServerSocketFactory) SSLServerSocketFactory.getDefault();
ServerSocket ss = ssf.createServerSocket(5432);
while (true) {
Socket s = ss.accept();
SSLSession session = ((SSLSocket) s).getSession();
Certificate[] cchain2 = session.getLocalCertificates();
for (int i = 0; i < cchain2.length; i++) {
System.out.println(((X509Certificate) cchain2[i]).getSubjectDN());
}
System.out.println("Peer host is " + session.getPeerHost());
System.out.println("Cipher is " + session.getCipherSuite());
System.out.println("Protocol is " + session.getProtocol());
System.out.println("ID is " + new BigInteger(session.getId()));
System.out.println("Session created in " + session.getCreationTime());
System.out.println("Session accessed in " + session.getLastAccessedTime());
PrintStream out = new PrintStream(s.getOutputStream());
out.println("Hi");
out.close();
s.close();
}
}
}
my client code:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.math.BigInteger;
import java.net.Socket;
import java.security.cert.Certificate;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
public class MainClass {
public static void main(String args[]) throws Exception {
System.setProperty("javax.net.ssl.trustStore", "C:\\Users\\nima\\Downloads\\test.dat");
SSLSocketFactory ssf = (SSLSocketFactory) SSLSocketFactory.getDefault();
Socket s = ssf.createSocket("127.0.0.1", 5432);
SSLSession session = ((SSLSocket) s).getSession();
Certificate[] cchain = session.getPeerCertificates();
System.out.println("The Certificates used by peer");
for (int i = 0; i < cchain.length; i++) {
System.out.println(((X509Certificate) cchain[i]).getSubjectDN());
}
System.out.println("Peer host is " + session.getPeerHost());
System.out.println("Cipher is " + session.getCipherSuite());
System.out.println("Protocol is " + session.getProtocol());
System.out.println("ID is " + new BigInteger(session.getId()));
System.out.println("Session created in " + session.getCreationTime());
System.out.println("Session accessed in " + session.getLastAccessedTime());
BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
String x = in.readLine();
System.out.println(x);
in.close();
}
}
my server code is from here and in both server and client side i get null from getLocalCertificates. It's also possible that all of my code would be wrong.
(From comments, expanded slightly)
If SSLSocket.getSession() is called before the handshake is done, it tries to do it, but if the handshake fails getSession() swallows the exception and just returns a 'nullSession' object which doesn't have the data a real session object would. Either (1) set sysprop javax.net.debug=ssl (at startup, usually on commandline with -D) and look at what it logs to see what is wrong with your handshake or (2) explicitly call ((SSLSocket)s).startHandshake() (which in spite of the name actually runs the handshake to completion, successful or not) and see what it throws.
In particular if you use the keystore file created by the first code shown, that contains only a certificate (trustedCertEntry) NOT a privateKeyEntry (with both privatekey and certificate/chain) as is necessary and required for an SSL/TLS server to use any of the common and default-enabled suites; this error will usually manifest, somewhat confusingly, as a handshake failure with 'no cipher[suite] in common' or 'no cipher[suite] overlap'.
That second part (SSL/TLS server without a privatekey doesn't work) has been asked and answered many times, but I don't recall any dupes that also include the 'getSession masks the error' part.
We're trying to make secure http communication between client an server.
The server provided the certificates, we took them, install them and we start running, the point is to exchange an exact number of messages simultaneously between the client and server consecutively, the problem that's driving us crazy is that between the requests, at SSLHANDSHAKE we get randomly the exception javax.net.ssl.SSLException: Received fatal alert: unexpected_message exactly at ServerHello handshake phase, and i don't know how or why this is happening while it keeps working fine for 98% of the other requests.
it crashes at step 2.

The function sendToVD() does the main work of the exchange between the client and the server.
At Client-End :
A web application with JSF managing the front layer, spring managing the beans life cycle, the communication entry to the client is assured by Servlets.
The client is deployed in a RedHat Linux machine, all TLS_VERSIONS are enbaled, JDK_8.
At Server-Side: i can't post the detailed information about the target URL for security measures, but it follows the following pattern https://ip:port/path, and it supports TLS_v1.2.
Hope you can help me out.

I have coded this client ssl code for java which works great and sends the wave file to a server. I am trying now to change or use this code on Android but I am having problems doing so. The questions that I have are things such as:
How do I set the pathStore and trustStoreFile(which directories are these on the android)?
Where do I upload the certificate file to(trustStoreFile) ?
Are there any settings that I need to configure?
Is this code what I need to use to accomplish the task of sending the wav file to the server that is listening?
Thanks so much !

Give some suggestions...How would i be able to transfer the data over channel?
The way you are using available() is specifically warned against in the Javadoc. Use a fixed size buffer, and block in the read() method.
