+
+* `MBEDTLS_PSA_CRYPTO_C && MBEDTLS_PSA_ACCEL_ALG_xxx`, i.e. when the PSA Crypto core is built with Mbed TLS and the `xxx` is accelerated through a driver.

+
 ```
-int psa_can_do_hash(psa_algorithm_t hash_alg);
+static int md_can_use_psa(const mbedtls_md_info_t *info)
 ```
 
-The job of this private function is to return 1 if `hash_alg` can be performed through PSA now, and 0 otherwise. It is only defined on algorithms that are enabled via PSA.
+Internally this function does the following:
 
-As a starting point, return 1 if PSA crypto's driver subsystem has been initialized.
+* First of all it converts the `mbedtls_md_info_t` to `psa_algorithm_t`. The result of this conversion is based on the `MBEDTLS_MD_xxx_VIA_PSA` symbols: if an algorithm does not have the corresponding `MBEDTLS_MD_xxx_VIA_PSA` enabled, then `md_can_use_psa` will return false.
 
-Usage note: for algorithms that are not enabled via PSA, calling `psa_can_do_hash` is generally safe: whether it returns 0 or 1, you can call a PSA hash function on the algorithm and it will return `PSA_ERROR_NOT_SUPPORTED`.
+* `int psa_can_do_hash(psa_algorithm_t hash_alg)` is then used to further checking if the PSA Crypto core has been initialized or not. If so then `md_can_use_psa` will finally succeed, otherwise it will fail.

 PSA has its own HMAC implementation. In builds with both `MBEDTLS_MD_C` and `PSA_WANT_ALG_HMAC` not fully provided by drivers, we should have a single implementation. Replace the one in `md.h` by calls to the PSA driver interface. This will also give mixed-domain modules access to HMAC accelerated directly by a PSA driver (eliminating the need to a HMAC interface in software if all supported hashes have an accelerator that includes HMAC support).
 
-### Improving support for `MBEDTLS_PSA_CRYPTO_CLIENT`
-
-So far, MD light only dispatches to PSA if an algorithm is available via `MBEDTLS_PSA_CRYPTO_C`, not if it's available via `MBEDTLS_PSA_CRYPTO_CLIENT`. This is acceptable because `MBEDTLS_USE_PSA_CRYPTO` requires `MBEDTLS_PSA_CRYPTO_C`, hence mixed-domain code never invokes PSA.
-
-The architecture can be extended to support `MBEDTLS_PSA_CRYPTO_CLIENT` with a little extra work. Here is an overview of the task breakdown, which should be fleshed up after we've done the first [migration](#migration-to-md-light):
-
-* Compile-time dependencies: instead of checking `defined(MBEDTLS_PSA_CRYPTO_C)`, check `defined(MBEDTLS_PSA_CRYPTO_C) || defined(MBEDTLS_PSA_CRYPTO_CLIENT)`.
-* Implementers of `MBEDTLS_PSA_CRYPTO_CLIENT` will need to provide `psa_can_do_hash()` (or a more general function `psa_can_do`) alongside `psa_crypto_init()`. Note that at this point, it will become a public interface, hence we won't be able to change it at a whim.
