| /** \brief Configure entropy sources. |
| * |
| * This function may only be called before a call to psa_crypto_init(), |
| * or after a call to mbedtls_psa_crypto_free() and before any |
| * subsequent call to psa_crypto_init(). |
| * |
| * This function is only intended for test purposes. The functionality |
| * it provides is also useful for system integrators, but |
| * system integrators should configure entropy drivers instead of |
| * breaking through to the Mbed TLS API. |
| * |
| * \param entropy_init Function to initialize the entropy context |
| * and set up the desired entropy sources. |
| * It is called by psa_crypto_init(). |
| * By default this is mbedtls_entropy_init(). |
| * This function cannot report failures directly. |
| * To indicate a failure, set the entropy context |
| * to a state where mbedtls_entropy_func() will |
| * return an error. |
| * \param entropy_free Function to free the entropy context |
| * and associated resources. |
| * It is called by mbedtls_psa_crypto_free(). |
| * By default this is mbedtls_entropy_free(). |
| * |
| * \retval PSA_SUCCESS |
| * Success. |
| * \retval PSA_ERROR_NOT_PERMITTED |
| * The caller does not have the permission to configure |
| * entropy sources. |
| * \retval PSA_ERROR_BAD_STATE |
| * The library has already been initialized. |
