In my application, I need to work on the SSLSocket. I have this code which is working on Android6.0 and above and When I run the same code on Android version 5.+ I am getting HandshakeException
private void openSSLSocket(String mHost, int mPort){
try {
SocketFactory sf = SSLSocketFactory.getDefault();
mSocket = (SSLSocket) sf.createSocket(mHost, mPort);
mSocket.setEnabledProtocols(new String[]{"TLSv1"});
mInputStream = mSocket.getInputStream();
mOutputStream = mSocket.getOutputStream();
mSocket.setSoTimeout(0);
}catch (Exception e){
e.printStackTrace();
}
}
I have read this article on android developer site and implemented the below code I got the .crt file for the server admin
private void openSSLSocketWithCA(String mHost, int mPort) {
try{
// Load CAs from an InputStream
// (could be from a resource or ByteArrayInputStream or ...)
CertificateFactory cf = CertificateFactory.getInstance("X.509");
// From https://www.washington.edu/itconnect/security/ca/load-der.crt
InputStream caInput = am.open("star_******_chained.crt");
Certificate ca;
try {
ca = cf.generateCertificate(caInput);
System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());
} 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 context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
SSLSocketFactory sf = context.getSocketFactory();
mSocket = (SSLSocket) sf.createSocket(mHost, mPort);
mSocket.setEnabledProtocols(new String[]{"TLSv1"});
mInputStream = mSocket.getInputStream();
mOutputStream = mSocket.getOutputStream();
mSocket.setSoTimeout(0);
}catch (Exception e){
e.printStackTrace();
}
}
even then I am getting HandshakeException when calling mSocket.getInputStream(); method
here is the log
W/System.err: javax.net.ssl.SSLHandshakeException: Handshake failed
W/System.err: at com.android.org.conscrypt.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:374)

After a lot of searching on web. I have landed on this page Updating security provider Finally, this solution worked for me
I have called this piece of code in onCreate of my main activity
try {
ProviderInstaller.installIfNeeded(this);
} catch (GooglePlayServicesRepairableException e) {
GooglePlayServicesUtil.getErrorDialog(e.getConnectionStatusCode(), callingActivity, 0);
} catch (GooglePlayServicesNotAvailableException e) {
Log.e("SecurityException", "Google Play Services not available.");
}
This solved my issue
