https://devzone.nordicsemi.com/f/nordic-q-a/51605/nrf52840-mbdedtls-with-cc310-hardware-accelerationHello Nordic team, I&#39;m currently looking into TLS on nRF52840, I&#39;m using nRF SDK 15.3.0. I have seend the DTLS example &quot;nRF5v15.3.0\examples\iot\dtls\coap_client&quot; that uses the external mbedtls library for both TLS and the crypto algorithms.

The closest you get is the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/crypto/doc/nrf_cc310_mbedcrypto.html">nrf_cc310_mbedcrypto</a>&nbsp;library, but it is not very mature. Also, it is integrated with the nRF Connect SDK (which is used for nRF91), and not the nRF5 SDK.</p><div style="clear:both;"></div>
