Does Android Volley support SSL?

Question

Does anyone know if Volley supports SSl in Android? Is there a way to support SSL through Volley?

Answer 1

You can link to my working sample code. Hope this helps!

public class MainActivity extends AppCompatActivity { private TextView mTextView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTextView = (TextView) findViewById(R.id.textView); String url = "https://192.168.1.100/testvolley"; HurlStack hurlStack = new HurlStack() { @Override protected HttpURLConnection createConnection(URL url) throws IOException { HttpsURLConnection httpsURLConnection = (HttpsURLConnection) super.createConnection(url); try { httpsURLConnection.setSSLSocketFactory(getSSLSocketFactory()); httpsURLConnection.setHostnameVerifier(getHostnameVerifier()); } catch (Exception e) { e.printStackTrace(); } return httpsURLConnection; } }; final JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { try { mTextView.setText(response.toString(5)); } catch (JSONException e) { mTextView.setText(e.toString()); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { mTextView.setText(error.toString()); } }); final RequestQueue requestQueue = Volley.newRequestQueue(this, hurlStack); requestQueue.add(jsonObjectRequest); } // Let assume your server app is hosting inside a server machine // which has a server certificate in which "Issued to" is "localhost",for example. // Then, inside verify method you can verify "localhost". // If not, you can temporarily return true private HostnameVerifier getHostnameVerifier() { return new HostnameVerifier() { @Override public boolean verify(String hostname, SSLSession session) { //return true; // verify always returns true, which could cause insecure network traffic due to trusting TLS/SSL server certificates for wrong hostnames HostnameVerifier hv = HttpsURLConnection.getDefaultHostnameVerifier(); return hv.verify("localhost", session); } }; } private TrustManager[] getWrappedTrustManagers(TrustManager[] trustManagers) { final X509TrustManager originalTrustManager = (X509TrustManager) trustManagers[0]; return new TrustManager[]{ new X509TrustManager() { public X509Certificate[] getAcceptedIssuers() { return originalTrustManager.getAcceptedIssuers(); } public void checkClientTrusted(X509Certificate[] certs, String authType) { try { if (certs != null && certs.length > 0){ certs[0].checkValidity(); } else { originalTrustManager.checkClientTrusted(certs, authType); } } catch (CertificateException e) { Log.w("checkClientTrusted", e.toString()); } } public void checkServerTrusted(X509Certificate[] certs, String authType) { try { if (certs != null && certs.length > 0){ certs[0].checkValidity(); } else { originalTrustManager.checkServerTrusted(certs, authType); } } catch (CertificateException e) { Log.w("checkServerTrusted", e.toString()); } } } }; } private SSLSocketFactory getSSLSocketFactory() throws CertificateException, KeyStoreException, IOException, NoSuchAlgorithmException, KeyManagementException { CertificateFactory cf = CertificateFactory.getInstance("X.509"); InputStream caInput = getResources().openRawResource(R.raw.my_cert); // this cert file stored in \app\src\main\res\raw folder path Certificate ca = cf.generateCertificate(caInput); caInput.close(); KeyStore keyStore = KeyStore.getInstance("BKS"); keyStore.load(null, null); keyStore.setCertificateEntry("ca", ca); String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm(); TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm); tmf.init(keyStore); TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers()); SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(null, wrappedTrustManagers, null); return sslContext.getSocketFactory(); } } 

IMO, you should also read further Google Documentation - Security with HTTPS and SSL

Answer 2

Yes of course.

Android Volley is a library that you can use to easily and efficiently manage network operations via http. If the base layer uses SSL (i.e. Https) or not, it is completely unconnected.

In other words: Volley's structure is agnostic to the TCP layer, and SSL only affects the TCP layer.
