/** \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.
