More and more customers are asking about the Espressif ESP32 RISC-V SoC products. The answer is an enthusiastic YES. We support all of the Espressif ESP-32 chipsets, including the ESP32-C6 and the ESP32-C3 RISC-V devices.
Check out our recent video: Getting Started with wolfSSL on the ESP32. Our Espressif examples make it easier than ever to take wolfSSL for a test drive. See also the recent blog on the ESP Component Registry and other blogs on the ESP32 topic.
Shown below is an out-of-the-box, default-settings version of wolfSSL running the Benchmark app on the ESP32-C3 in a typical ESP-IDF v5.1 environment. Keep in mind there are numerous wolfSSL settings to fine-tune our libraries to your product.
We currently have RISC-V hardware acceleration in development. This means that some of the performance metrics should improve by upwards of 10x faster.
