<p>The accelerator interface lets you drivers for external cryptoprocessors into an implementation of the <a href="../#application-programming-interface">PSA Cryptography API</a>. External cryptoprocessors such as secure elements and smart cards perform cryptographic operations with keys accessed via opaque handles.</p>
<p><strong>Status: draft</strong> — major changes are still likely.</p>

+<p><strong>Mbed Crypto support status</strong>: Partial. Only a few operations are supported: key pair generation, import, export and destruction; signature and verification.</p>
+<p><strong>Example</strong>: You can see the code of an <a href="https://github.com/ARMmbed/mbed-os-atecc608a">example driver</a> for the <a href="https://www.microchip.com/wwwproducts/en/ATECC608A">Microchip ATECC608A secure element</a>.
