- This change will introduce a breaking change for SoCs with the HMAC peripheral. Turning on flash encryption will no longer enable NVS encryption automatically. Closes https://github.com/espressif/esp-idf/issues/12549

NVS Encryption
|
|
--------------
|
|
|
|
- For SoCs with the HMAC peripheral (``SOC_HMAC_SUPPORTED``), turning on :doc:`Flash Encryption <../../../security/flash-encryption>` will no longer automatically turn on :doc:`NVS encryption <../../../api-reference/storage/nvs_encryption>`.
|
|
- You will need to explicitly turn on NVS encryption and select the required scheme (flash encryption-based or HMAC peripheral-based). You can select the HMAC peripheral-based scheme (:ref:`CONFIG_NVS_SEC_KEY_PROTECTION_SCHEME`), even if flash encryption is not enabled.
|
|
- SoCs without the HMAC peripheral will still automatically turn on NVS encryption when flash encryption is enabled.
