ESP-CRYPTOAUTHLIB

Supported Targets

Supported Target Board ESP32 ESP32-C2 ESP32-C3 ESP32-C5 ESP32-C6 ESP32-C61 ESP32-H2 ESP32-P4 ESP32-S3

This is a port of Microchip's cryptoauthlib for ESP-IDF. It contains necessary build support to use cryptoauthlib with ESP-IDF as well as esp_cryptoauthlib_utility for configuring and provisiong ATECC608A chip connected to a Supported Target Board. The cryptoauthlib folder which is a subset of Microchip's cryptoauthlib is created with help of script generate_component.sh.

Requirements

  • ESP-IDF version should be release/v5.0 or newer.
  • Environment variable IDF_PATH should be set
