Did it myself, just my mistake :) Doing in in a hurry.
...fixed it ;) Thx for the review :) -

Has anyone successfully flashed Espruino on this chip?

Have you seen ESP32 S2 Mini V1.0.0 Development Board with ESP32-S2FN4R2 4MB FLASH 2MB PSRAM?
There is hope :)

I have read both Encryption threads:
https://forum.espruino.com/conversations/267841/
https://forum.espruino.com/conversations/273427/So after 7 years we just have SHA256 in crypto for ESP build in?
I was hoping to find some AES-like included solution.I went through git repo and read readme for building, but for windows there was only information: basically do it in Linux. Unfortunately not a solution I can use. I was hoping it can be done in Windows with Python :)
Could you add additional builds for ESP chips with AES, so there is one with and one without for each?

Hi guys :)
I found old NodeMCU Lolin v3 board and I am playing with it :)
I am wondering how to encrypt securely message on espruino and decrypt it on api.
I am looking for a way to ensure that only my device can add records to database.
I want to send only temperature and humidity so there is not much data.
I was thinking about RSA or AES or whatever can fit into this little thing.
AES would be super cool to use but require('crypto').AES doesn't seem to work after flashing with ESP8266 4MB.
Key to encrypt and decrypt message can be safely stored on the api and espruino - so that would work over unsecured networks.
I want to use HTTPS or TLS if possible, but I am just starting to look around after couple of years break from espruino project what has changed and from what I can choose from :) -
I have read about XXTEA and other libraries but unfortunately failed to upload it to ESP board. Too large or too resource hungry... but still fighting :)
Once a grandmaster in the noble art of Pixel-Wrangling and Font-Finessing, with a venerable 15-year reign over the kingdoms of Computer Graphics and DTP Operations, I found myself at a crossroads in the grand year of 2016. In a move that shocked the masses (or at least my cat), I hung up my virtual brushes and laid down my rulers, embarking on a quest most daring. I traded the safety of my artistic haven for the wild, untamed lands of Programming, seeking to don the mantle of a Software Engineer.
Yes, you read that right. After a decade and a half of making the digital canvas my domain, commanding armies of pixels with the ease of a seasoned general, I decided to confront the final boss: Code itself. Like a wizard choosing to forsake his magical staff for the arcane secrets of another realm, I plunged headfirst into this new adventure.
And so, here I stand (or sit, given the nature of the job), a transformed entity. I am no longer just the artist who could make your photos pop and your layouts sing but also the engineer who weaves logic and creativity into a tapestry of code. From visual maestro to software sage, my journey has been nothing short of a quest for the ages, chronicled here for your reading pleasure.
