HTTPS support on Pico!

This is great news, Gordon. Thanks!

I'm looking to use the AWS IoT services. The primary protocol is MQTT encrypted with TLS, identity is managed using X.509 certificates (validated via TLS1.2 client authentication mode).

It looks like most of the pieces are in place for this, but I wanted to make sure I'm not missing something in terms of device capability in using the certificates / encryption.

http://docs.aws.amazon.com/iot/latest/developerguide/identity-in-iot.html

Here's the key requirements:

Clients must support all of the following in their TLS implementation to use AWS IoT certificates:

• TLSv1.2
  
• SHA-256 RSA certificate signature validation
  
• One of the following cipher suites: ( found here )
  

Thanks!
