wolfSSL Support for ESP-IDF and ESP32-WROOM-32

Are you a user of the ESP-IDF(Espressif IoT Development Framework)? If so, you will be happy to know that wolfSSL recently added support and example projects to the wolfSSL embedded SSL/TLS library for ESP-IDF.

ESP-IDF is intended for rapidly developing Internet-of-Things (IoT) applications, with Wi-Fi, Bluetooth, power management and several other system features.

The ESP-IDF “Get Started” document can be found here:


In order to use wolfSSL under ESP-IDF, you need to deploy wolfSSL source files into the IDE. Please see the README.md placed in the “IDE/Espressif/ESP-IDF/” directory of wolfSSL source tree. In addition to that, example projects including TLS server/client, wolfCrypt test and benchmark are also provided. For building these examples, please see each README.md in example projects directories. When working with ESP-IDF, wolfSSL worked with the ESP32-WROOM-32 device.

wolfSSL also has a page that elaborates upon the use of Espressif with wolfSSL and the Espressif hardware devices, located here: https://www.wolfssl.com/docs/espressif/

Our wolfSSL master branch can be cloned here:

The README.md can be found here:

Additional examples for wolfSSL TLS Client/Server and wolfCrypt test/benchmark applications can be found here:

This support is currently located in our GitHub master branch, and will roll into the next stable release of wolfSSL as well. For any questions or help getting wolfSSL up and running on your ESP-IDF environment, please contact us at support@wolfssl.com.
