+ *       crypto client when the PSA crypto implementation is not included in
+ *       the library (MBEDTLS_PSA_CRYPTO_C disabled). The code included is the
+ *       code to set and get PSA key attributes.
+ *       The development of PSA drivers partially relying on the library to
+ *       fulfill the hardware gaps is another possible usage of this option.
+ *
+ * \warning This interface is experimental and may change or be removed
