* This means that PSA core was built with the corresponding PSA_WANT_ALG_xxx
* set and that psa_crypto_init has already been called.

* \param hash_alg The hash algorithm (ignored for now).
* \note When using Mbed TLS version of PSA core (i.e. MBEDTLS_PSA_CRYPTO_C is
* set) for now this function only checks the state of the driver
* subsystem, not the algorithm. This might be improved in the future.

* \param hash_alg The hash algorithm.
