| <h1 id="psa-entropy-source-driver-interface">PSA entropy source driver interface</h1> |
| <p>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 <a href="../#application-programming-interface">PSA Cryptography API</a>.</p> |
| <p><strong>Status: draft</strong> — major changes are still likely.</p> |
| <p><strong>Documentation</strong>: for now, please see the header file: <a href="https://github.com/ARMmbed/mbed-crypto/blob/development/include/psa/crypto_entropy_driver.h"><code>include/psa/crypto_entropy_driver.h</code></a></p> |
| <p><strong>Mbed Crypto support status</strong>: Not implemented yet. For now, entropy sources use the <a href="https://tls.mbed.org/kb/how-to/add-entropy-sources-to-entropy-pool">Mbed TLS entropy module</a>.</p> |
