如果缺少 cryptsetup-bin 是否意味着设备内的文件未加密？

请帮助我了解 cryptsetup 的工作原理，以及 cryptsetup-bin 的缺失对 cryptsetup 有何影响

答案1

cryptsetup-bin 是 cryptsetup 的依赖项，但 cryptsetup-bin 不需要 cryptsetup 即可运行。

从结果来看apt show cryptsetup-bin：

Description: disk encryption support - command line tools
 Cryptsetup provides an interface for configuring encryption on block
 devices (such as /home or swap partitions), using the Linux kernel
 device mapper target dm-crypt. It features integrated Linux Unified Key
 Setup (LUKS) support.

从结果来看apt show cryptsetup：

Description: disk encryption support - startup scripts
 Cryptsetup provides an interface for configuring encryption on block
 devices (such as /home or swap partitions), using the Linux kernel
 device mapper target dm-crypt. It features integrated Linux Unified Key
 Setup (LUKS) support.

要在所有当前支持的 Ubuntu 版本中安装 cryptsetup-bin，请打开终端并输入：

sudo apt install cryptsetup-bin
