I need my Arduino to connect to my web server through HTTPS, can the Arduino handle it?

It only has to act as a client.

  • Please state which Arduino. There are quite a few different ones.

  • I was just checking if it was possible to do some secure cloud connected sensors with the cheap non Linux Arduinos.

It sounds like a better way to do it would be to have a PHP script act as handoff server (maybe protected by originating IP address) to access the HTTPS site and provide the data over a less processor-intensive protocol.

How to get HTTPS on Arduino?

However, another answer suggests that we are working towards a solution to your issue, but it's not quite there yet (~12 seconds to encrypt a packet).
