How to send an encrypted post request using Esp8266-arduino?

I have a simple sql database on an asp.net server.

This database will log temp data sent from an esp8266 programmed with arduino ide.

1- how would I go about security? Knowing that esp8266 cant handle ssl.

2- how would I stop man in middle attacks?

3- how would I stop anyone from send a fake post request to my server and populate my database?

Solution

  • The ESP8266 absolutely can handle SSL. In fact, the Arduino repository includes an SSL client as part of it's libraries.

    Here is an example showing SSL in action to perform a basic HTTP request: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/HTTPSRequest/HTTPSRequest.ino
