Use Secure Element (ATECC608) for TLS
_____________________________________
A secure element (ATECC608) can be also used for the underlying TLS connection in the HTTP client connection. Please refer to Secure Element with ESP-TLS section in the :doc:` ESP-TLS documentation</api-reference/protocols/esp_tls` for more details. The secure element support has to be first enabled in menuconfig through :ref:`CONFIG_ESP_TLS_USE_SECURE_ELEMENT`. Then the HTTP client can be configured to use secure element as follows:
.. code-block:: c
esp_http_client_config_t cfg = {
/* other configurations options */
.use_secure_element = true,
};
