I don't think there's a full code example anywhere, but you should be able to use the getPeerCertificate() method in node.js to do this: https://nodejs.org/api/tls.html#tls_tlssocket_getpeercertificate_detailed. That method will give you the SHA-1 hash of the full chain if you call it with the detailed parameter as true. From the request, you can grab the official Alexa signature, hash each part of the chain, and then compare those values to the peer ones. Let me know if this method works or if you run into any issues with it. -Nick
