However, SSL can be rather demanding for the ESP8266 and when enabled, you're left with much less memory for your application. As a lightweight alternative, you can encrypt only the data payload.. As bearssl is already integrated. Do you know any tutorial or example code to do (ChaCha20, for instance) encryption using bearssl? I do not need all the SSL and certificates related stuff. What I need to do is: - Negotiate a shared key using ECDH - Create an encryption context - Add Key and IV - Feed data to encrypt - Delete context Regards Teams. Q&A for work. Connect and share knowledge within a single location that is structured and easy to search. Learn mor It will basically be a system where values from sensors attached to multiple ESP8266 will be sent to the server that will log them (data will probably be like SENS1=1232&SENS2=4322 or JSON or similar before encryption). I would like to group the values from the different ESP8266 clients (by MAC or similar) and want to make sure that no one else can insert fake data into the system, hence the encryption For the other two problems, the end-to-end encryption and remote server identity, the Arduino port for ESP8266 has a nice secure client library called WiFiClientSecure. It's not really a state of the art, but if used properly, it will do the job just right. The WiFiClientSecure uses a TLS implementation which is based on the axTLS library. It.

One of the biggest advantages of using the ESP8266 in your projects is how easy it is to get WiFi up and running. Just plug in the WiFi library, put the SSID and encryption key in your source code.
SSL encryption makes use of a public certificate (with public key) and a private key, known only by the server. In order to decrypt traffic between devices, someone should own both the public key and the private one. As long as you keep the private key... private, the connection is safe even if the browser complains it doesn't trust your self signed certificate. Remember that ESP8266 is not. RFID Sensor Tutorial for Arduino, ESP8266 and ESP32. In this tutorial you learn everything you have to know about RFID for your next project with an Arduino, ESP8266 or ESP32 microcontroller. After we learn the basics of a RFID system, we see how power and data is transferred between the RFID reader and the tag In the case of the mbed TLS implementation, the encryption function supports only a single block of 16 bytes in ECB mode. Since we are using AES-128, then the key needs to also have a length of 16 bytes. Finally, the output data buffer also needs to have a length of 16 bytes, so we need to make sure to pass to this function a buffer with enough.
Make your own risk analysis and, depending on the application, decide what library functions to implement. If required, consider implementation of other means of protection from being hacked, like exposing modules for uploads only according to a specific schedule, triggering OTA only when the user presses a dedicated Update button wired to the ESP, etc. Advanced Security - Signed Updates.
