Https Connection Android
I am doing a https post and I'm getting 开发者_运维技巧an exception of ssl exception Not trusted server certificate. If i do normal http it is working perfectly fine. Do I have to accept the server certificate somehow?
This is what I am doing. It simply doesn't check the certificate anymore.
// always verify the host - dont check for certificate
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
/**
* Trust every server - dont check for any certificate
*/
private static void trustAllHosts() {
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[] {};
}
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
} };
// Install the all-trusting trust manager
try {
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection
.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
e.printStackTrace();
}
}
and
HttpURLConnection http = null;
if (url.getProtocol().toLowerCase().equals("https")) {
trustAllHosts();
HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
https.setHostnameVerifier(DO_NOT_VERIFY);
http = https;
} else {
http = (HttpURLConnection) url.openConnection();
}
I'm making a guess, but if you want an actual handshake to occur, you have to let android know of your certificate. If you want to just accept no matter what, then use this pseudo-code to get what you need with the Apache HTTP Client:
SchemeRegistry schemeRegistry = new SchemeRegistry ();
schemeRegistry.register (new Scheme ("http",
PlainSocketFactory.getSocketFactory (), 80));
schemeRegistry.register (new Scheme ("https",
new CustomSSLSocketFactory (), 443));
ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager (
params, schemeRegistry);
return new DefaultHttpClient (cm, params);
CustomSSLSocketFactory:
public class CustomSSLSocketFactory extends org.apache.http.conn.ssl.SSLSocketFactory
{
private SSLSocketFactory FACTORY = HttpsURLConnection.getDefaultSSLSocketFactory ();
public CustomSSLSocketFactory ()
{
super(null);
try
{
SSLContext context = SSLContext.getInstance ("TLS");
TrustManager[] tm = new TrustManager[] { new FullX509TrustManager () };
context.init (null, tm, new SecureRandom ());
FACTORY = context.getSocketFactory ();
}
catch (Exception e)
{
e.printStackTrace();
}
}
public Socket createSocket() throws IOException
{
return FACTORY.createSocket();
}
// TODO: add other methods like createSocket() and getDefaultCipherSuites().
// Hint: they all just make a call to member FACTORY
}
FullX509TrustManager is a class that implements javax.net.ssl.X509TrustManager, yet none of the methods actually perform any work, get a sample here.
Good Luck!

When developing an application that uses https, your test server doesn't have a valid SSL certificate. Or sometimes the web site is using a self-signed certificate or the web site is using free SSL certificate. So if you try to connect to the server using Apache HttpClient, you will get a exception telling that the "peer not authenticated". Though it is not a good practice to trust all the certificates in a production software, you may have to do so according to the situation.
This solution resolves the exception caused by "peer not authenticated".
But before we go to the solution, I must warn you that this is not a good idea for a production application. This will violate the purpose of using a security certificate. So unless you have a good reason or if you are sure that this will not cause any problem, don't use this solution.
Normally you create a HttpClient like this.
HttpClient httpclient = new DefaultHttpClient();
But you have to change the way you create the HttpClient.
First you have to create a class extending org.apache.http.conn.ssl.SSLSocketFactory.
import org.apache.http.conn.ssl.SSLSocketFactory;
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;
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 create a method like this.
public HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
Then you can create the HttpClient.
HttpClient httpclient = getNewHttpClient();
If you are trying to send a post request to a login page the rest of the code would be like this.
private URI url = new URI("url of the action of the form");
HttpPost httppost = new HttpPost(url);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("username", "user"));
nameValuePairs.add(new BasicNameValuePair("password", "password"));
try {
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
You get the html page to the InputStream. Then you can do whatever you want with the returned html page.
But here you will face a problem. If you want to manage a session using cookies, you will not be able to do it with this method. If you want to get the cookies, you will have to do it via a browser. Then only you will receive cookies.
If you are using a StartSSL or Thawte certificate, it will fail for Froyo and older versions. You can use a newer version's CAcert repository instead of trusting every certificate.
Any of this answers didn't work for me so here is code which trust any certificates.

return Cur_SSL_Context.getSocketFactory().createSocket(socket, host, port, autoClose);
}
@Override

{
return Cur_SSL_Context.getSocketFactory().createSocket();
}
}

This is a known problem with Android 2.x. I was struggling with this problem for a week until I came across the following question, which not only gives a good background of the problem but also provides a working and effective solution devoid of any security holes.
'No peer certificate' error in Android 2.3 but NOT in 4
For some reason the solution mentioned for httpClient above didn't worked for me. At the end I was able to make it work by correctly overriding the method when implementing the custom SSLSocketFactory class.
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose)
throws IOException, UnknownHostException
{
return sslFactory.createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return sslFactory.createSocket();
}
This is how it worked perfectly for me. You can see the full custom class and implementing on the following thread: http://blog.syedgakbar.com/2012/07/21/android-https-and-not-trusted-server-certificate-error/
I make this class and found
package com.example.fakessl;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import android.util.Log;
public class CertificadoAceptar {
private static TrustManager[] trustManagers;
public static class _FakeX509TrustManager implements
javax.net.ssl.X509TrustManager {
private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[] {};
public void checkClientTrusted(X509Certificate[] arg0, String arg1)
throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] arg0, String arg1)
throws CertificateException {
}
public boolean isClientTrusted(X509Certificate[] chain) {
return (true);
}
public boolean isServerTrusted(X509Certificate[] chain) {
return (true);
}
public X509Certificate[] getAcceptedIssuers() {
return (_AcceptedIssuers);
}
}
public static void allowAllSSL() {
javax.net.ssl.HttpsURLConnection
.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
javax.net.ssl.SSLContext context = null;
if (trustManagers == null) {
trustManagers = new javax.net.ssl.TrustManager[] { new _FakeX509TrustManager() };
}
try {
context = javax.net.ssl.SSLContext.getInstance("TLS");
context.init(null, trustManagers, new SecureRandom());
} catch (NoSuchAlgorithmException e) {
Log.e("allowAllSSL", e.toString());
} catch (KeyManagementException e) {
Log.e("allowAllSSL", e.toString());
}
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(context
.getSocketFactory());
}
}
in you code white this
CertificadoAceptar ca = new CertificadoAceptar();
ca.allowAllSSL();
HttpsTransportSE Transport = new HttpsTransportSE("iphost or host name", 8080, "/WS/wsexample.asmx?WSDL", 30000);
Sources that helped me get to work with my self signed certificate on my AWS Apache server and connect with HttpsURLConnection from android device:
SSL on aws instance - amazon tutorial on ssl
Android Security with HTTPS and SSL - creating your own trust manager on client for accepting your certificate
Creating self signed certificate - easy script for creating your certificates
Then I did the following:
- Made sure the server supports https (sudo yum install -y mod24_ssl)
- Put this script in a file
create_my_certs.sh:
#!/bin/bash FQDN=$1 # make directories to work from mkdir -p server/ client/ all/ # Create your very own Root Certificate Authority openssl genrsa \ -out all/my-private-root-ca.privkey.pem \ 2048 # Self-sign your Root Certificate Authority # Since this is private, the details can be as bogus as you like openssl req \ -x509 \ -new \ -nodes \ -key all/my-private-root-ca.privkey.pem \ -days 1024 \ -out all/my-private-root-ca.cert.pem \ -subj "/C=US/ST=Utah/L=Provo/O=ACME Signing Authority Inc/CN=example.com" # Create a Device Certificate for each domain, # such as example.com, *.example.com, awesome.example.com # NOTE: You MUST match CN to the domain name or ip address you want to use openssl genrsa \ -out all/privkey.pem \ 2048 # Create a request from your Device, which your Root CA will sign openssl req -new \ -key all/privkey.pem \ -out all/csr.pem \ -subj "/C=US/ST=Utah/L=Provo/O=ACME Tech Inc/CN=${FQDN}" # Sign the request from Device with your Root CA openssl x509 \ -req -in all/csr.pem \ -CA all/my-private-root-ca.cert.pem \ -CAkey all/my-private-root-ca.privkey.pem \ -CAcreateserial \ -out all/cert.pem \ -days 500 # Put things in their proper place rsync -a all/{privkey,cert}.pem server/ cat all/cert.pem > server/fullchain.pem # we have no intermediates in this case rsync -a all/my-private-root-ca.cert.pem server/ rsync -a all/my-private-root-ca.cert.pem client/
- Run
bash create_my_certs.sh yourdomain.com Place the certificates in their proper place on the server (you can find configuration in /etc/httpd/conf.d/ssl.conf). All these should be set:
SSLCertificateFile
SSLCertificateKeyFile
SSLCertificateChainFile
SSLCACertificateFileRestart httpd using
sudo service httpd restartand make sure httpd started:
Stopping httpd: [ OK ]
Starting httpd: [ OK ]Copy
my-private-root-ca.certto your android project assets folderCreate your trust manager:
SSLContext SSLContext;
CertificateFactory cf = CertificateFactory.getInstance("X.509"); InputStream caInput = context.getAssets().open("my-private-root-ca.cert.pem"); Certificate ca; try { ca = cf.generateCertificate(caInput); } finally { caInput.close(); }
// Create a KeyStore containing our trusted CAs String keyStoreType = KeyStore.getDefaultType(); KeyStore keyStore = KeyStore.getInstance(keyStoreType); keyStore.load(null, null); keyStore.setCertificateEntry("ca", ca); // Create a TrustManager that trusts the CAs in our KeyStore String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm(); TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm); tmf.init(keyStore); // Create an SSLContext that uses our TrustManager SSLContext = SSLContext.getInstance("TLS"); SSSLContext.init(null, tmf.getTrustManagers(), null);And make the connection using HttpsURLConnection:
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection(); connection.setSSLSocketFactory(SSLContext.getSocketFactory());
Thats it, try your https connection.
Probably you can try something like this. This helped me
SslContextFactory sec = new SslContextFactory();
sec.setValidateCerts(false);
sec.setTrustAll(true);
org.eclipse.jetty.websocket.client.WebSocketClient client = new WebSocketClient(sec);
Just use this method as your HTTPClient:
public static HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
加载中,请稍侯......
