    wolfSSL DTLS1.3 ESP32 Examples Now Available

    • Have you heard about secure UDP packets? Yes, you can enjoy the security of TLS1.3 level encryption but use UDP instead of TCP on the ESP32. It’s called DTLS. The UDP packets are typically used in lossy, unreliable networks such as LoRa (low-power, long-range radio networks). Most people interested in secure UDP are using the […]
