Important notice

Due to legal restrictions, support for hardware-accelerated cryptography utilizing ARM CryptoCell-310 is only available in mbedTLS library (libmbedcrypto.a) provided with the nRF5 SDK for Thread. 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 library provided with the SDK.
