 Flash encryption is intended for encrypting the contents of the {IDF_TARGET_NAME}'s off-chip flash memory. Once this feature is enabled, firmware is flashed as plaintext, and then the data is encrypted in place on the first boot. As a result, physical readout of flash will not be sufficient to recover most flash contents.
 
-With flash encryption enabled, the following types of data are encrypted by default:
-
-- Firmware bootloader
-- Partition Table
-- All "app" type partitions
-
-Other types of data can be encrypted conditionally:
-
-- Any partition marked with the ``encrypted`` flag in the partition table. For details, see :ref:`encrypted-partition-flag`.
-- Secure Boot bootloader digest if Secure Boot is enabled (see below).

 flash 加密功能用于加密与 {IDF_TARGET_NAME} 搭载使用的片外 flash 中的内容。启用 flash 加密功能后，固件会以明文形式烧录，然后在首次启动时将数据进行加密。因此，物理读取 flash 将无法恢复大部分 flash 内容。
 
-启用 flash 加密后，系统将默认加密下列类型的 flash 数据：
-
-- 固件引导加载程序
-- 分区表
-- 所有 “app” 类型的分区
-
-其他类型的数据将视情况进行加密：
-
-- 任何在分区表中标有“加密”标志的分区。详情请见 :ref:`encrypted-partition-flag`。
