DEMO program with ATECC608A on ESP-WROOM-32SE

Overview

Running demo programs with ATECC608A on 32SE by setting WOLFSSL_ESPWROOM32SE definition

Including the following examples:

• simple tls_client/tls_server
• crypt benchmark

The user_settings.h file enables some of the hardened settings.

Requirements

1. ESP-IDF development framework
   [https://docs.espressif.com/projects/esp-idf/en/latest/get-started/]

2. Microchip CryptoAuthentication Library
   [https://github.com/MicrochipTech/cryptoauthlib]

Setup

1. wolfSSL under ESP-IDF. Please see README.md

2. CryptoAuthentication Library under ESP-IDF. Please see README.md

3. Uncomment out #define WOLFSSL_ESPWROOM32SE in /path/to/wolfssl/wolfssl/wolfcrypt/settings.h

   Note : Need to enable WOLFSSL_ESPIDF
   Note : crypt test will fail if enabled WOLFSSL_ESPWROOM32SE

Configuration

1. The user_settings.h can be found in /path/to/esp-idf/components/wolfssl/include/user_settings.h

Build examples

1. See README in each example folder
