+This repository contains the steps and the code to Access the AWS IoT service using Python3, Paho-MQTT on Windows, Linux/Ubuntu and Raspberry Pi3.

+Requirements:																   
+1. Python 3.4.x																   
+2. Paho-MQTT         "pip install paho-mqtt"												   
+3. SSL               "sudo apt-get install libssl-dev"
+
+1. Go to Amazon IoT website and follow this Guide "http://docs.aws.amazon.com/iot/latest/developerguide/iot-device-sdk-c.html".
+2. Click on "Create a Resource".
+3. Choose "Create a thing", type a name for the thing, and then choose Create.
+4. In addition to a confirmation message, the View thing button will be displayed.
+5. Choose View thing to display information about your "thing". Here, thing is the shadow of the device that you want to connect to AWS IoT Service.
+6. Choose the Connect a device button to download a key pair and a certificate generated by AWS IoT.
+7. On the Connect a device page, select the SDK to use, and then choose Generate certificate and policy. We will use "Embedded C" here.
+8. This will generate an X.509 certificate and key pair; activate the X.509 certificate; and create an AWS IoT policy and attach it to the certificate.
+9. Next you will get to see the Download Links for the certificates and the keys. Download them all.
+10. Choose Confirm & start connecting.
