发布于:2024-06-26 ⋅ 阅读:(101) ⋅ 点赞:(0)

一、安装软件与使用

1.安装ecryptfs

在终端下输入:

sudo apt-get install ecryptfs-utils

2.创建登录密码和挂载密码

ecryptfs-setup-private

输入密码。
最后两行,yes, no

Would you like to proceed with the mount (yes/no)?  yes  你从未用这个密码挂载过,是否继续?
Would you like to append sig [86a764759a1f7625] to
[/root/.ecryptfs/sig-cache.txt]
in order to avoid this warning in the future (yes/no)?  no  是否将此次挂载信息记录下来以免下次报警?
Not adding sig to user sig cache file; continuing with mount.

3. 挂载文件夹

mount -t ecryptfs /opt/test /opt/test
一直回车

4. 在文件夹里创建文档

5.卸载文件夹

umount -t ecryptfs /opt/test

2.卸载软件

1. 卸载private文件夹

由于我有一个private挂载了, 我先卸载

sudo umount /home/xiaoxin/Private

2. 删除.ecryptfs文件夹

(base) xiaoxin@xiaoxin:~$ ls -a
 .               .java                 .selected_editor

 .ecryptfs       .profile              .Xauthority
 .gem            .psensor              .xinputrc
 .gnupg          Public                .xsession-errors
 .imagej         .python_history       .xsession-errors.old

根目录下删除
