java - Problems with https (No peer certificate) in android

Question

Problem

I want to send https request to the site https://10.2.20.20/fido/EzPay/login.php my own server and get response from it and save it for example in a string. I have found some example codes in internet and try to test them for my problem but they are not helpful. Below I present some parts of codes which I have tested.

Code Example:

I try this code, but I always get same exception "No peer certificate" Why ?

try
{
    HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;

    DefaultHttpClient client = new DefaultHttpClient();

    SchemeRegistry registry = new SchemeRegistry();
    SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
    socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
    registry.register(new Scheme("https", socketFactory, 443));
    SingleClientConnManager mgr = new SingleClientConnManager(client.getParams(), registry);
    DefaultHttpClient httpClient = new DefaultHttpClient(mgr, client.getParams());

    // Set verifier      
    HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);

    // Example send http request
    final String url = "https://10.2.20.20/fido/EzPay/login.php";
    HttpPost httpPost = new HttpPost(url);
    HttpResponse response = httpClient.execute(httpPost);

    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    String line = "";
    while ((line = rd.readLine()) != null) {
        Log.i(DownloadImageTask.class.getName(), line);
    }

}
catch(IOException ex)
{
    Log.e(DownloadImageTask.class.getName(), ex.getMessage());
}

Exception.

Question

What I'm doing wrong and how I can solve this issue. Why I get "No peer certificate" exception ?

Thanks.

Answer 1

Finally I have solved https problem. As I fought the main problem was in server, concretely in certificate. Android supports only “BKS” certificate and that’s was the reason that we can’t get response from the server. In order to solve this issue I have read more then 30 articles and finally found solution.

The steps which I done to solve this issue you can see below:

First thing that I do was generating .bks keystore file from our fidoserver.crt certificate, in order to do that I have read this article and do following:

1. Open cmd
2. Go to JDK folder “cd X:ProgramsJavaJdk6in”
3. Call following command:

keytool -import -alias tomcat -file X://KeyStore/fidoserver.crt -keypass password - keystore X://KeyStore/keystore.bks -storetype BKS -storepass 222222 -providerClass org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath X://KeyStore/bcprov-jdk16-146.jar

Before running this command I have download Bouncy Castle .jar file and put it in the folder with certificates. After doing this all steps I get keystore.bks file which is the right certificate file for Android application. I put this file in Androids mnc/sdcard folder. In java code I have write following code to read that keystore.bbk file

KeyStore trustStore  = KeyStore.getInstance( "BKS" /*KeyStore.getDefaultType()*/ );
FileInputStream instream = new FileInputStream(new File("/mnt/sdcard/keystore.bks"));
try {
    trustStore.load(instream, "222222".toCharArray());
} catch (NoSuchAlgorithmException e) {
    e.printStackTrace();
} catch (CertificateException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try { instream.close(); } catch (Exception ignore) {}
}

// Create socket factory with given keystore.
SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);

SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
Scheme sch = new Scheme("https", socketFactory, 443);
httpclient.getConnectionManager().getSchemeRegistry().register(sch);

HttpGet httpget = new HttpGet("https://10.2.20.20/fido/EzPay/login.php");

System.out.println("executing request " + httpget.getRequestLine());

HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();

System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (entity != null) {
    System.out.println("Response content length:  " + entity.getContentLength());
}
            
// Print html.
BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String line = "";
while ((line = in.readLine()) != null) {
     System.out.println(line);
}
in.close();

This all allow m to load our certificate with given password 222222 (password we give when create a keystore with keytool).

After this all my test application start to work correctly. Now I can send request to https and get response from it. I have tested application with FIDO server, everything works great! I think on Monday I will make some changes in EzPay application and it will start working with https connections.
