(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example requires ESP32 platform interfaced with Microchip's ATECC608A Secure Element.
For making the hardware connections with ATECC608A
chip (Secure Element), please refer this for details.
The example performs ECDSA sign/verify
functions on sample data using hardware private key stored in ATECC608A chip.
Before project configuration and build, be sure to set the correct chip target using idf.py set-target <chip_name>
.
- A development board with ESP32 series based SoC
ATECC608A
IC based external module or dev. board.- A USB cable for Power supply and programming
Hardware should be configured to run the example, for details on configuration of ATECC608A chip, please refer esp_cryptoauth_utility
Open the project configuration menu (idf.py menuconfig
).
In the Component config -> esp-cryptoauthlib
menu:
- Use
Choose the type of ATECC608A chip
to set the Crypto IC type [1]. - Use
Enable Hardware ECDSA keys for mbedTLS
Enable Hardware ECDSA.- Set
Enable ATECC608A sign operations in mbedTLS
to use Hardware ECDSA sign. - Set
Enable ATECC608A verify operations in mbedTLS
to use Hardware ECDSA verify.
- Set
- Set

Build the project and flash it to the board, then run the monitor tool to view the serial output:
Run idf.py -p PORT flash monitor
to build, flash and monitor the project.
(To exit the serial monitor, type Ctrl-]
.)
See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
