Hi Bernd,
Missed the sample program used
HttpsClient.java
================
import java.net.MalformedURLException;
import java.net.URL;
import java.security.cert.Certificate;
import java.io.*;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLPeerUnverifiedException;
public class HttpsClient {
public static void main(String[] args)
{
new HttpsClient().testIt();
}
private void testIt(){
// String https_url = "https://www.google.com/";;
String https_url = "
https://transparencyreport.google.com/https/overview?hl=en";;
URL url;
try {
url = new URL(https_url);
HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
//dumpl all cert info
print_https_cert(con);
//dump all the content
print_content(con);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private void print_https_cert(HttpsURLConnection con){
if(con!=null){
try {
System.out.println("Response Code : " + con.getResponseCode());
System.out.println("Cipher Suite : " + con.getCipherSuite());
System.out.println("\n");
Certificate[] certs = con.getServerCertificates();
for(Certificate cert : certs){
System.out.println("Cert Type : " + cert.getType());
System.out.println("Cert Hash Code : " + cert.hashCode());
System.out.println("Cert Public Key Algorithm : "
+ cert.getPublicKey().getAlgorithm());
System.out.println("Cert Public Key Format : "
+ cert.getPublicKey().getFormat());
System.out.println("\n");
}
} catch (SSLPeerUnverifiedException e) {
e.printStackTrace();
} catch (IOException e){
e.printStackTrace();
}
}
}
private void print_content(HttpsURLConnection con){
if(con!=null){
try {
System.out.println("****** Content of the URL ********");
BufferedReader br =
new BufferedReader(
new InputStreamReader(con.getInputStream()));
String input;
while ((input = br.readLine()) != null){
System.out.println(input);
}
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
