# ECDSA sign/verify Example with ESP32-WROOM-32SE
|
||
|
||
## Description
|
||
|
||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||
|
||
This example requires [ESP32-WROOM-32SE](https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32se_datasheet_en.pdf) which has Microchip's [ATECC608A](https://www.microchip.com/wwwproducts/en/ATECC608A) (Secure Element) integrated on the module.
|
||
|
||
The example performs `ECDSA sign/verify` functions on sample data using hardware private key stored in ATECC608A chip. If you want to use bare `ATECC608A` chip (Secure Element) with `ESP32-WROOM-32` module by making external connections, please refer [this](https://github.com/espressif/esp-cryptoauthlib/blob/master/esp_cryptoauth_utility/README.md#using-atecc608a-with-esp32-wroom-32) for details.
|
||
|
||
## How to use example
|
||
|
||
Before project configuration and build, be sure to set the correct chip target using `idf.py set-target <chip_name>`.
|
||
|
||
### Hardware Required
|
||
|
||
To get started you will need a `ESP32-WROOM-32SE` development board which integrates Microchip’s ATECC608A CryptoAuth chip in the module.
|
||
|
||
* A development board with ESP32-WROOM-32SE SoC or an custom board with the `ATECC608A` IC.
|
||
* A USB cable for Power supply and programming
|
||
|
||
### Configure the project
|
||
|
||
ATECC608A chip on ESP32-WROOM-32SE should be configured to run the example, for details on configuration of ATECC608A chip, please refer [esp_cryptoauth_utility](https://github.com/espressif/esp-cryptoauthlib/blob/master/esp_cryptoauth_utility/README.md#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 `I2C SDA pin used to communicate with the ATECC608A`.
|
||
* Set `I2C SCL pin used to communicate with the ATECC608A`.
|
||
|
||
[1]: for more details refer [Find ATECC608A chip type](https://github.com/espressif/esp-cryptoauthlib/blob/master/esp_cryptoauth_utility/README.md#find-type-of-atecc608a-chip-connected-to-esp32-wroom32-se).
|
||
|
||
### Build and Flash
|
||
|
||
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](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for all the steps to configure and use the ESP-IDF to build projects.
