SSL implementation over limited AT Commands (ESP32, AI Thinker A9G)

I'm working on a project on the ESP32 connected to an AI Thinker A9G through serial. Right now I'm using the AT commands the A9G is shipped with. I have to connect to a Google App Engine endpoint over https, but there is no AT command support for SSL on the A9G.

Is there a way to wrap the A9G at commands in a c++ ssl library on the ESP?

If so, what ssl library would you recommend?

It seems like a giant project, and I'm thinking about changing GPS/GPRS module to something with better SSL support.

AT commands are a rather limited interface for talking to Internet. If they work, it's a great shortcut. If they don't, well, they don't.

The ESP32 can support a ppp dialup stack natively, talk to Internet, do HTTPS requests etc. Just use the modem as a regular dumb old modem, a terminal to establish a data connection.
