NVS Encryption
--------------

- For SoCs with the HMAC peripheral (``SOC_HMAC_SUPPORTED``), turning on :doc:`../../../security/flash-encryption` will no longer automatically turn on :doc:`../../../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.
