* \brief This function returns the PSA algorithm identifier
* associated with the given digest type.
*
* \param md_type The type of digest to search for.
* \param md_type The type of digest to search for. Must not be NONE.
*
* \warning If \p md_type is \c MBEDTLS_MD_NONE, this function will
* not return \c PSA_ALG_NONE, but an invalid algorithm.
*
* \warning This function does not check if the algorithm is
* supported, it always returns the corresponding identifier.
