How to Configure ssl_manual_auth MQTT example for secure communication with test.mozilla.org?

[dhananjay.sutariya]

Hi all,
I am using the latest SDK.I've flashed the ssl_manual_auth standard example for secure MQTT connection. After performing the steps mentioned in README file i get stuck at this point :
Paste the generated CSR in the [Mosquitto test certificate signer](https://test.mosquitto.org/ssl/index.php), click Submit and copy the downloaded `client.crt` in the `main` directory.

(https://test.mosquitto.org/ssl/index.php) gives me a dialog box to download a file . (not sure what to do with that).

This is what bothers me :
Please note, that the supplied files `client.crt` and `client.key` in the `main` directory are only placeholders for your client certificate and key (i.e. the example "as is" would compile but would not connect to the broker).
So what kindof configurations are expected for successful connection?

Thanks,
