How to perform SSL operations on port 80

Question

I have a server.java file as:

import javax.net.ssl.*;
import java.io.*;
//*****************
public class Server
{
    public static void main(String[] args)
    {
        try {
            SSLServerSocketFactory sslserversocketfactory = (SSLServerSocketFactory)SSLServerSocketFactory.getDefault();
            SSLServerSocket sslserversocket =(SSLServerSocket)sslserversocketfactory.createServerSocket(80);

            SSLSocket sslsocket = (SSLSocket)
            sslserversocket.accept();

            InputStream is = sslsocket.getInputStream();
            InputStreamReader isr = new
            InputStreamReader(is);

            BufferedReader br = new BufferedReader(isr);
            String string = null;

            while ((string = br.readLine()) != null)
            {
            System.out.println(string);
            System.out.flush();
            }
        } 

        catch (Exception e){
            e.printStackTrace();
        }
    }
}

and a Client.java file as:

import javax.net.ssl.*;
import java.io.*;
//*****************
public class Client
{
    public static void main(String[] args)
    {
        try {
            SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
            SSLSocket sslsocket = (SSLSocket) sslsocketfactory.createSocket("127.0.0.1", 80);

            InputStream is = System.in;
            InputStreamReader isr = new InputStreamReader(is);

            BufferedReader br = new BufferedReader(isr);
            OutputStream os = sslsocket.getOutputStream();

            OutputStreamWriter osw = new OutputStreamWriter(os);
            BufferedWriter bw = new BufferedWriter(osw);

            String string = null;
            while ((string = br.readLine()) != null)
            {
            bw.write(string + '\n');
            bw.flush();
            }
        }
        catch (Exception e){
            e.printStackTrace();
        }
    }
}

also i created my own certificate like this:

C:\Temp>keytool -genkey -keystore myCertificate -keyalg RSA
Enter keystore password: abcdefg
Re-enter new password: abcdefg
What is your first and last name?
[Unknown]: first last
What is the name of your organizational unit?
[Unknown]: cs
What is the name of your organization?
[Unknown]: stackoverflow
What is the name of your City or Locality?
[Unknown]: NYC
What is the name of your State or Province?
[Unknown]: NY
What is the two-letter country code for this unit?
[Unknown]: us
Is CN=first last, OU=cs, O=stackoverflow, L=NYC, ST=NY, C=us correct?
[no]: yes
Enter key password for <mykey>
(RETURN if same as keystore password):

but no matter what i do i keep getting error as:

main, handling exception: javax.net.ssl.SSLHandshakeException: Remote host closed connection during
handshake
main, SEND TLSv1 ALERT:  fatal, description = handshake_failure
main, WRITE: TLSv1 Alert, length = 2

My concern is if i change the port from 80 to something else, the code works perfectly fine but i have to specifically work on this port itself. The certificate and both java files are in same folder. Can you guys help me figure out a way to perform SSL operations on port 80?

I know its not configured for that @Java1 but im asking for a way to implement this in such a way that this operation works — user9517536248, Apr 28 '14 at 05:32

I figured a way out to do it.

Basically what i did is used java's keystore to generate a keystore.jks file and then i used SSLContext to make my keystore certificate valid and hence performed SSL on port 80.

Thanks for help guys.

SSL is running on port 443。And it is default ,just like 80,no show on the adress bar.

This is not browser code. The OP has written his own server / client code. – Scary Wombat Apr 28 '14 at 05:36
