wolfSSL is excited to announce support for Espressif ESP32 hardware acceleration to the wolfSSL embedded SSL/TLS library!
The ESP32-WROOM-32 is a powerful, generic Wi-Fi+BLE MCU module with high flexibility, and is easily interactable with the wolfSSL embedded SSL/TLS library. As wolfSSL is highly portable and the ESP32-WROOM-32 is highly flexible, if your application has any special features that interfere with the existing wolfSSL port, they are easily remedied.
The new wolfSSL ESP32-WROOM-32 port functionality was added into the existing ESP-IDF port, and the ESP32-WROOM-32 functionality can be enabled by either defining the "WOLFSSL_ESPIDF" and “WOLFSSL_ESPWROOM32” or “WOLFSSL_ESPWROOM32SE” options in the settings.h file (or user_settings.h alternatively, if WOLFSSL_USER_SETTINGS is defined). For more details about this new ESP32 support, please see the REAMDE.md placed in the “<wolfssl-root>/wolfcrypt/src/port/Espressif” directory of the wolfSSL source tree. Details about the ESP-IDF port can be found in the README.md file located in "<wolfssl-root>/IDE/Espressif/".
wolfSSL's support for the onboard hardware cryptography of the ESP32 and ATECC608A gives users code size reductions and performance advantages. A full set of benchmarks and performance comparisons can be found on our ESP32-specific webpage, located here: https://www.wolfssl.com/docs/espressif/.
