Important notice
Due to legal restrictions, support for hardware-accelerated cryptography utilizing ARM CryptoCell-310 or ARM CryptoCell-312 is only available in libraries.
- The nRF5 SDK for Thread provides an mbedTLS library.
- The nRF Connect SDK provides nrf_cc3xx crypto libraries.
The library available in the OpenThread repository does not support hardware acceleration. You can still use it, but the commissioning procedure takes much more time in such cases. For the best performance and user experience, use the libraries provided with the SDKs.
