Self-signed certificate and loopj for Android

I'm trying to use loopj for making async

HTTP
requests. Works great, except when I try to access https site with self-signed cert. I get

javax.net.ssl.SSLPeerUnverifiedException: No peer certificate.


I guess the default ssl options can be overriding using
setSSLSocketFactory(SSLSocketFactory sslSocketFactory)
method, but I'm not sure how to do it or it might not be the right way at all.

Please suggest how can I solve this issue ?

Answer

You do it almost exactly the same as explained here for HttpClient except a little bit simpler - Trusting all certificates using HttpClient over HTTPS

Create a custom class:

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.conn.ssl.SSLSocketFactory;
public class MySSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
}

Then when you create your client instance:

try {
      KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
      trustStore.load(null, null);
      sf = new MySSLSocketFactory(trustStore);
      sf.setHostnameVerifier(MySSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
      client.setSSLSocketFactory(sf);   
    }
    catch (Exception e) {   
    }
