The accelerator interface lets you drivers for entropy sources such as Hardware Random Number Generators (HRNG), also known as True Random Number Generators (TRNG), into an implementation of the PSA Cryptography API.
Status: draft — major changes are still likely.
Documentation: for now, please see the header file: include/psa/crypto_entropy_driver.h
Mbed Crypto support status: Not implemented yet. For now, entropy sources use the Mbed TLS entropy module.
