Provide certificate validation code

Expected Behavior

The SDK should handle all the steps of URL and certificate validation as described in the documentation. As this is required for certification, the API should have this built in. Various attempts exist such as https://github.com/anjishnu/ask-alexa-pykit/blob/cherrypy_0.3_release/lib/validation_utils.py or
https://www.dizmo.com/amazon-alexa-signature-verification/

Current Behavior

Ideally, this would be hooked into the request processing and handled seamlessly for custom skills that do not use AWS Lambda.

Context

Trying to develop a custom skill was greatly helped by the sample code for invocation. Even better would be to enhance that so it handles validation as well and can result in a skill that passes verification.

Hey @cadir , thanks for the feature request.

#53 only talks about deploying skill code on other than AWS Lambda services, but as you have mentioned, the request should also be validated as per the Alexa developer documentation. We will take in this feature request and tag it along with #53 to provide the support through SDK.

Closing this feature request and tracking this through #53 , which mentions support for other than AWS Lambda deployments, sample skill and documentation.
