@ -3,7 +3,7 @@ Flash Encryption
Flash Encryption is a feature for encrypting the contents of the ESP32's attached SPI flash. When flash encryption is enabled, physical readout of the SPI flash is not sufficient to recover most flash contents.
Flash Encryption is separate from the :doc:`Secure Boot <secure-boot>` feature, and you can use flash encryption without enabling secure boot. However we recommend using both features together for a secure environment. In absence of secure boot, additional configuration needs to be performed to ensure effectiveness of flash encryption. See :ref:`flash-encryption-without-secure-boot` for more details.

Enabling flash encryption limits your options for further updates of your ESP32. Make sure to read this document (including :ref:`flash-encryption-limitations`) and understand the implications of enabling flash encryption.
