Has TLS been an issue since ESP32? I know ESP8266 had to increase CPU speed to be able to do RSA without timing out the watchdog. Wonderful hack. Didn't think ESP32 had the same issue.

Anyway, the S31 has SHA, AES, ECC, RSA, and ECDSA accelerators, so that should be fine. https://documentation.espressif.com/esp32-s31_datasheet_en.p...
