This is my first post and I'm going to try to do my best to be as clear as possible (sorry for my english).
Here is my trouble, I'm using retrofit:1.9.0 and okhttp:2.7.5 to perform API call. Everything was fine until my server provider disable SLLv2 and SSLv3 cause of sercurity trouble (Drown fail found on first March).
Now I check the information about my provider and he allows only TLSv1 with cypher (TLS 1.0 TLS_RSA_WITH_3DES_EDE_CBC_SHA No FS) from https://www.ssllabs.com/.
Ok so this is all the tests I've done and results:
[UPDATE PROBLEM SOLVED]
Find a way to solve this problem in my second answer.
UPDATE It seems that the problems comes from the google API version. When I test on API 18 everything is working fine. When it's on Android greather or equal to 5.0.0 it fails.
First test
Conf. recap:
- compileSdkVersion 23
- buildToolsVersion '23.0.2'
- minSdkVersion 18
- targetSdkVersion 21
- retrofit:1.9.0
- okhttp:2.7.5
- Android version > 5.0.0 (but it's the same on every device...)
Rest Client (LoginRestClient):
public class LoginRestClient
{
private static final String BASE_URL = "";
private LoginApiService apiService;
public LoginRestClient()
{
Gson gson = new GsonBuilder()
.setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
.create();
RestAdapter restAdapter = new RestAdapter.Builder()
.setLogLevel(RestAdapter.LogLevel.FULL)
.setEndpoint(ApiIntentService.getHostAddress())
.setConverter(new GsonConverter(gson))
.setClient(new OkClient(ApiIntentService.getConnectionHttpClient()))
.build();
apiService = restAdapter.create(LoginApiService.class);
}
public LoginApiService getApiService() {
return apiService;
}
}
Function to create client OkHttpClient getConnectionHttpClient()
public static OkHttpClient getConnectionHttpClient()
{
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);
ConnectionSpec specs = new ConnectionSpec.Builder(ConnectionSpec.COMPATIBLE_TLS)
.tlsVersions(TlsVersion.TLS_1_0)
.cipherSuites(CipherSuite.TLS_RSA_WITH_3DES_EDE_CBC_SHA)
.build();
okHttpClient.setConnectionSpecs(Collections.singletonList(specs));
return okHttpClient;
}
Result in public void failure(RetrofitError error) from custom CallBack
java.net.UnknownServiceException: Unable to find acceptable protocols. isFallback=false, modes=[ConnectionSpec(cipherSuites=[TLS_RSA_WITH_3DES_EDE_CBC_SHA], tlsVersions=[TLS_1_0], supportsTlsExtensions=true)], supported protocols=[SSLv3, TLSv1, TLSv1.1, TLSv1.2]
Second test
I've made a custom SSLSocketFactory to disable SSLv3 and force TLS:
/**
* @author fkrauthan
*/
public class TLSSocketFactory extends SSLSocketFactory {
private SSLSocketFactory internalSSLSocketFactory;
public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
internalSSLSocketFactory = context.getSocketFactory();
}
@Override
public String[] getDefaultCipherSuites() {
return internalSSLSocketFactory.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return internalSSLSocketFactory.getSupportedCipherSuites();
}
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
}
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
}
@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
}
private Socket enableTLSOnSocket(Socket socket) {
if(socket != null && (socket instanceof SSLSocket)) {
((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1"});
}
return socket;
}
}
I use it like this:
public static OkHttpClient getConnectionHttpClient()
{
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);
try {
TLSSocketFactory tlsSocketFactory = new TLSSocketFactory();
HttpsURLConnection.setDefaultSSLSocketFactory(tlsSocketFactory);
okHttpClient.setSslSocketFactory(tlsSocketFactory);
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return okHttpClient;
}
Result in public void failure(RetrofitError error) from custom CallBack
javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x7f87885280: Failure in SSL library, usually a protocol error error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:770 0x7f87c2fdf0:0x00000000)
If anyone can help me It will be very cool. All my apps are down and I'm fighting against this problem since yesterday morning to restore my services. I'm removing my hair one by one...
Thanks in advance.
