Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: protocolo de enlace SSL cancelado: falla en la biblioteca SSL, generalmente un error de protocolo
Estoy intentando ejecutar el siguiente código en Android
URLConnection l_connection = null;
// Create connection
uzip=new UnZipData(mContext);
l_url = new URL(serverurl);
if ("https".equals(l_url.getProtocol())) {
System.out.println("<<<<<<<<<<<<< Before TLS >>>>>>>>>>>>");
sslcontext = SSLContext.getInstance("TLS");
System.out.println("<<<<<<<<<<<<< After TLS >>>>>>>>>>>>");
sslcontext.init(null,
new TrustManager[] { new CustomTrustManager()},
new java.security.SecureRandom());
HttpsURLConnection
.setDefaultHostnameVerifier(new CustomHostnameVerifier());
HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext
.getSocketFactory());
l_connection = (HttpsURLConnection) l_url.openConnection();
((HttpsURLConnection) l_connection).setRequestMethod("POST");
} else {
l_connection = (HttpURLConnection) l_url.openConnection();
((HttpURLConnection) l_connection).setRequestMethod("POST");
}
/*System.setProperty("http.agent", "Android_Phone");*/
l_connection.setConnectTimeout(10000);
l_connection.setRequestProperty("Content-Language", "en-US");
l_connection.setUseCaches(false);
l_connection.setDoInput(true);
l_connection.setDoOutput(true);
System.out.println("<<<<<<<<<<<<< Before Connection >>>>>>>>>>>>");
l_connection.connect();
Encendido l_connection.connect()
, está dando esto SSLhandshakeException
. A veces funciona, pero la mayoría de las veces da la excepción. Sólo sucede en el emulador de Android 4.0. Lo probé en Android 4.4 y 5.0, funciona bien. ¿Qué podría ser la causa?

Encontré la solución analizando los paquetes de datos usando Wireshark. Lo que encontré es que al establecer una conexión segura, Android recurría a SSLv3 desde TLSv1 . Es un error en las versiones de Android <4.4 y se puede resolver eliminando el protocolo SSLv3 de la lista de Protocolos habilitados. Creé una clase socketFactory personalizada llamada NoSSLv3SocketFactory.java. Utilice esto para hacer una fábrica de enchufes.

Utilice esta clase de esta manera mientras se conecta:
SSLContext sslcontext = SSLContext.getInstance("TLSv1");
sslcontext.init(null, null, null);
SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(sslcontext.getSocketFactory());
HttpsURLConnection.setDefaultSSLSocketFactory(NoSSLv3Factory);
l_connection = (HttpsURLConnection) l_url.openConnection();
l_connection.connect();
ACTUALIZAR :
Ahora, la solución correcta sería instalar un proveedor de seguridad más nuevo utilizando los servicios de Google Play :
ProviderInstaller.installIfNeeded(getApplicationContext());
Esto efectivamente le da a su aplicación acceso a una versión más reciente de OpenSSL y Java Security Provider, que incluye soporte para TLSv1.2 en SSLEngine. Una vez instalado el nuevo proveedor, puede crear un SSLEngine que admita SSLv3, TLSv1, TLSv1.1 y TLSv1.2 de la forma habitual:
SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
SSLEngine engine = sslContext.createSSLEngine();
O puede restringir los protocolos habilitados usando engine.setEnabledProtocols
.
No olvide agregar la siguiente dependencia ( consulte la última versión aquí ):
implementation 'com.google.android.gms:play-services-auth:17.0.0'

Recibía excepciones de SSLHandshake en dispositivos que ejecutaban versiones de Android anteriores a Android 5.0. En mi caso de uso, también quería crear un TrustManager para confiar en mi certificado de cliente.
Implementé NoSSLv3SocketFactory y NoSSLv3Factory para eliminar SSLv3 de la lista de protocolos compatibles de mi cliente, pero no pude lograr que ninguna de estas soluciones funcionara.
Algunas cosas que aprendí:
- En dispositivos anteriores a Android 5.0, los protocolos TLSv1.1 y TLSv1.2 no están habilitados de forma predeterminada.
- El protocolo SSLv3 no está deshabilitado de forma predeterminada en dispositivos anteriores a Android 5.0.
- SSLv3 no es un protocolo seguro y, por lo tanto, es deseable eliminarlo de la lista de protocolos admitidos de nuestro cliente antes de realizar una conexión.
Lo que funcionó para mí
Permita que la seguridad de Android Provider
se actualice al iniciar su aplicación.
El proveedor predeterminado anterior a 5.0+ no desactiva SSLv3. Siempre que tenga acceso a los servicios de Google Play, es relativamente sencillo parchear el proveedor de seguridad de Android desde su aplicación.
private void updateAndroidSecurityProvider(Activity callingActivity) {
try {
ProviderInstaller.installIfNeeded(this);
} catch (GooglePlayServicesRepairableException e) {
// Thrown when Google Play Services is not installed, up-to-date, or enabled
// Show dialog to allow users to install, update, or otherwise enable Google Play services.
GooglePlayServicesUtil.getErrorDialog(e.getConnectionStatusCode(), callingActivity, 0);
} catch (GooglePlayServicesNotAvailableException e) {
Log.e("SecurityException", "Google Play Services not available.");
}
}
Si ahora crea su OkHttpClient o HttpURLConnection, TLSv1.1 y TLSv1.2 deberían estar disponibles como protocolos y SSLv3 debería eliminarse. Si el cliente/conexión (o más específicamente su SSLContext) se inicializó antes de llamar, ProviderInstaller.installIfNeeded(...)
será necesario volver a crearlo.
No olvide agregar la siguiente dependencia ( la última versión se encuentra aquí ):
compile 'com.google.android.gms:play-services-auth:16.0.1'
Fuentes:
- Parchear el proveedor de seguridad con ProviderInstaller Provider
- Hacer que SSLEngine use TLSv1.2 en Android (4.4.2)

I didn't need to explicitly set which cipher algorithms my client should use but I found a SO post recommending those considered most secure at the time of writing: Which Cipher Suites to enable for SSL Socket?
