javax.net.ssl.sslpeerunverifiedexception no peer certificate - android

I am trying to insert a record into MySQL by posting data to a PHP server from an Android app. I have added the INTERNET permission to AndroidManifest.xml
I get javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
Android code
private void senddata(ArrayList<NameValuePair> data)
{
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://10.0.2.2/insert222.php");
httppost.setEntity(new UrlEncodedFormEntity(data));
HttpResponse response = httpclient.execute(httppost);
}
catch (Exception e) {
// TODO: handle exception
Log.e("log_tag", "Error: "+e.toString());
}
}
Can anyone help?

Warning: Do not implement this in production code you are ever going to use on a network you do not entirely trust. Especially anything going over the public internet. This link gives more correct answer. Here is an implementation using SSL.
Your problem is you are using DefaultHttpClient for https(secure url).
Create a custom DefaultHttpClient
public static HttpClient createHttpClient()
{
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET);
HttpProtocolParams.setUseExpectContinue(params, true);
SchemeRegistry schReg = new SchemeRegistry();
schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params, schReg);
return new DefaultHttpClient(conMgr, params);
}
Than change your code as follows:
HttpClient httpclient = createHttpClient();
HttpPost httppost = new HttpPost("https://10.0.2.2/insert222.php");
httppost.setEntity(new UrlEncodedFormEntity(data));
HttpResponse response = httpclient.execute(httppost);
Have a look at here if you have problems
It should work.

I had this issue with an IIS 8 server. In the https binding, I had to uncheck the checkbox labeled "Require Server Name Indication." Once I unchecked it, I quit getting the error.

I have to say all trusted certificates (trusted by authorized centres such as COMODO, Symantec, etc.) have to be work in any case. If your app recieves such javax.net.ssl.SSLPeerUnverifiedException: No peer certificate using bought certificate you give something wrong on server side.
To test use openssl s_client -connect example.com:443 command to get inner information about certificate your app recieve.
In may case my nginx-server sent wrong certificate in some cases.

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

There are dozens of posts about this issue (javax.net.ssl.SSLPeerUnverifiedException: No peer certificate) but I haven't found anything that works for me.
Many posts (like this, and this) "solve" this by allowing all certificates to be accepted but, of course, this is not a good solution for anything other than testing.
Others seem quite localized and don't work for me. I really hope that someone has some insight that I lack.
So, my problem: I'm testing on a server accessible only through the local network, connecting via HTTPS. Making the call I need to through the browser works fine. No complaining about certificates and if you check the certificates, it all looks good.
When I try on my Android device, I get javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
Here's the code that calls it:
StringBuilder builder = new StringBuilder();
builder.append( /* stuff goes here*/ );
httpGet.setEntity(new UrlEncodedFormEntity(nameValuePairs));
ResponseHandler<String> responseHandler = new BasicResponseHandler();
// Execute HTTP Post Request. Response body returned as a string
HttpClient httpClient = MyActivity.getHttpClient();
HttpGet httpGet = new HttpGet(builder.toString());
String jsonResponse = httpClient.execute(httpGet, responseHandler); //Line causing the Exception
My code for MyActivity.getHttpClient():
protected synchronized static HttpClient getHttpClient(){
if (httpClient != null)
return httpClient;
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, TIMEOUT_CONNECTION);
HttpConnectionParams.setSoTimeout(httpParameters, TIMEOUT_SOCKET);
HttpProtocolParams.setVersion(httpParameters, HttpVersion.HTTP_1_1);
//Thread safe in case various AsyncTasks try to access it concurrently
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schemeRegistry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
ClientConnectionManager cm = new ThreadSafeClientConnManager(httpParameters, schemeRegistry);
httpClient = new DefaultHttpClient(cm, httpParameters);
CookieStore cookieStore = httpClient.getCookieStore();
HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
return httpClient;
}
Any help would be much appreciated.
Edit
Also just to mention I've had other SSL issues with another app but adding the SchemeRegistry portion fixed it for me before.
Edit 2
So far I've only tested on Android 3.1, but I need this to work on Android 2.2+ regardless. I just tested on the browser on my Android tab (Android 3.1) and it complains about the certificate. It's fine on my pc browser, but not on the Android browser or in my app.
Edit 3
Turns out the iOS browser also complains about it. I'm starting to think it's a certificate chain issue described here (SSL certificate is not trusted - on mobile only)
It turns out my code was fine and the problem was that the server was not returning the full certificate chain. For more information see this SO post and this superuser post:
SSL certificate is not trusted - on mobile only
https://superuser.com/questions/347588/how-do-ssl-chains-work
Try below code :-
BasicHttpResponse httpResponse = null;
HttpPost httppost = new HttpPost(URL);
HttpParams httpParameters = new BasicHttpParams();
// Set the timeout in milliseconds until a connection is
// established.
int timeoutConnection = ConstantLib.CONNECTION_TIMEOUT;
HttpConnectionParams.setConnectionTimeout(httpParameters,
timeoutConnection);
// Set the default socket timeout (SO_TIMEOUT)
// in milliseconds which is the timeout for waiting for data.
int timeoutSocket = ConstantLib.CONNECTION_TIMEOUT;
HttpConnectionParams
.setSoTimeout(httpParameters, timeoutSocket);
DefaultHttpClient httpClient = new DefaultHttpClient(
httpParameters);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair(ConstantLib.locale,
locale));
In my case everything used to work fine. Suddenly after 2 days my device did not show any https site or image link.
After some investigation it turns out that My time settings was not up to date on device.
I changed my time settings properly and it worked.
I had this exception when I used self-signed certificate + ip address. Just add these lines
HostnameVerifier allHostsValid = new HostnameVerifier() {
#Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
and your HttpURLConnection will work.
That trick is not related to validation against CA! So if I specify wrong CA and use that trick, I will get another exception. So the host remains trusted
Just in case, I will leave code for specifying your own CA here:
String certStr = context.getString(R.string.caApi);
X509Certificate ca = SecurityHelper.readCert(certStr);
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(null);
ks.setCertificateEntry("caCert", ca);
tmf.init(ks);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, tmf.getTrustManagers(), null);
HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());
Do not forget to use cool feature buildTypes and place different CAs for debug/release in res folder.

Calling WCF from android over https with credentials

I am trying to call my RESTful WCF service over https on Android. I keep getting a 401: unauthorized error whenever I make the call. The other parts of my code work, ive tested it locally.
Here is the pertinent code:
// http scheme
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
// https scheme
schemeRegistry.register(new Scheme("https", new EasySSLSocketFactory(), 443));
credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
new UsernamePasswordCredentials("user", "pass"));
clientConnectionManager = new ThreadSafeClientConnManager(params, schemeRegistry);
context = new BasicHttpContext();
context.setAttribute("http.auth.credentials-provider", credentialsProvider);
HttpGet request = new HttpGet(SERVICE_URI + URL1 + EID);
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
DefaultHttpClient client = new DefaultHttpClient(clientConnectionManager, params);
client.setCredentialsProvider(credentialsProvider);
HttpResponse response = client.execute(request, context);
HttpEntity responseEntity = response.getEntity();
EasySSLSocketFactory uses an implementation of X509TrustManager. I know that code works as well. Can someone please provide some advice. Nothing I have found works correctly.
Turns out, HttpClient doen't support NTLM authentication out of the box (im using IIS with windows auth). This link gave me everything I needed. Just copy and paste and forget about it.

Make execute() of HttpDefaultClient very slow

I have massive performance problems with the execute method of the execute() method of the HttpDefaultClient.
I'm currently using this to post data to a Server, receiving JSON and deserialize the data. A call takes 8s to 30s on my phone. If I switch to Wifi (it's pretty fast, the same call takes 300ms on my PC) it takes 3s to 8s. At least 90% of that time is spend in the execute method.
Is use this code:
HttpPost post = new HttpPost(DEST_URL);
HashMap<String, String> params = req.getPostParams();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
for (String key : params.keySet()) {
nameValuePairs.add(new BasicNameValuePair(key, params.get(key)));
}
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
post.setHeader(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
HttpResponse response = httpClient.execute(post); // very slow!
return response;
We also develop an iOS app which is able to do the same within 1 to 2s. Is there a quicker way for http (https in the future)?
Creating the client like this:
HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER;
final SSLSocketFactory socketFactory = SSLSocketFactory
.getSocketFactory();
socketFactory
.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", socketFactory, 443));
HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
HttpClient client = new DefaultHttpClient(params);
Using: HTC Wildfire, Android 2.2.1
codes above works fine.
if i create an httpclient the following way:
DefaultHttpClient httpClient = new DefaultHttpClient();
// httpclient
httpClient.getParams().setParameter(
CoreConnectionPNames.CONNECTION_TIMEOUT, mConnectionTimeOut);
httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,
mSocketTimeOut);
for first time to post data to server and got response , it cost me 10--20 seconds.
but if i create an HttpClient following the answer above.
when first time to post data to server and got response , it cost just 4 seconds,and i think it works fine .

HTTPS In Android

I have implemented HTTP Post to post data to the backend. How do I implement HTTPS in Android (I have already configured the backend for https)?
I googled and found some solutions:
Secure HTTP Post in Android
and tried them but I do not receive any data in the backend.
Is it the correct way to implement? Is there any other method?
Below is my code snippet:
File file = new File(filepath);
HttpClient client = new DefaultHttpClient();
//String url = "http://test.....;
String url = "https://test......";
HttpPost post = new HttpPost(url);
FileEntity bin = new FileEntity(file, url);
post.setEntity(bin);
HttpResponse response = client.execute(post);
HttpEntity resEntity = response.getEntity();
Basically I am using fileentity to do a HTTPPost. Now I want to do this over https. After implementing https over at the backend I just modified http to https in the url and tested again. And it is not working.
Any idea how do i resolve this?
Thanks In Advance,
Perumal
Make sure your http client supports the SSL socket:
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schemeRegistry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
HttpParams params = new BasicHttpParams();
ClientConnectionManager manager = new ThreadSafeClientConnManager(params, schemeRegistry);
HttpClient httpsClient = new DefaultHttpClient(manager, params);
and use this client to execute your POST request:
HttpPost post = new HttpPost("https://www.mysecuresite.com");
post.setHeader("Content-Type", "application/x-www-form-urlencoded");
post.setEntity(new StringEntity("This is the POST body", HTTP.UTF_8));
HttpResponse response = httpsClient.execute(post);

How can I connect to an Http server with Basic Auth over SSL on Android?

I know this question has been asked before but none of the answers I have found are helping me. I am trying to connect to a simple login service over SSL with Basic Http Auth. The service is hosted at https://localhost:8443/login. When I hit the service from a browser (on windows, OSX, and Android) it works fine, I put in my username and password and I am authenticated properly. However, when I try to do this through code on my Xoom I get a ClientProtocolException that says "the server failed to respond with a valid HTTP response". Can anyone give me a push in the right direction? Here is my code
String result = null;
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET);
HttpProtocolParams.setUseExpectContinue(params, true);
SchemeRegistry schReg = new SchemeRegistry();
schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params, schReg);
DefaultHttpClient client = new DefaultHttpClient(conMgr, params);
HttpGet get = new HttpGet(preferences.getString(getString(R.string.Security_Login_URL),
"https://localhost:80/login"));
String credentials = Base64.encodeToString((username + ":" + password).getBytes(), Base64.URL_SAFE);
if(credentials!=null){
get.addHeader("Authorization","Basic "+credentials);
ResponseHandler responseHandler=new BasicResponseHandler();
try {
result = client.execute(get, responseHandler);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Two common problems could cause this:
You should not do the BASIC authentication yourself. The Apache HttpClient has all the functionalities already included to do the BASIC authentication. Look either Basic Authentication or Preemptive BASIC authentication
Does your android device trusts the certificate from the server? When your browser trusts the cert, it doesn't mean that your device is also trusting it. Android has a very limited list of trusted certification authorities. You could check this from your device, when you visit the site on your Android built-in browser. If no warning message appears, everything should be OK. For further information about trusting additional certificates from an android device, you can look at my blog article.
Enjoy
