--------
|
|
|
|
Starting from **ESP-IDF v5.5**, there is a change in how the SHA sub-function APIs, :cpp:func:`esp_sha_block` and :cpp:func:`esp_sha_dma`, are used.
|
|
|
|
Previously, these APIs used to set the SHA mode internally, however, in the updated version, you must explicitly set the SHA mode before invoking them.
|
|
|
|
For instance, if you intend to use the **SHA-256** algorithm, you must first call :cpp:func:`esp_sha_set_mode` with the argument ``SHA2_256``:
|
|
|
|
.. code-block:: c
|
|
|
|
esp_sha_set_mode(SHA2_256);
