如何进行linux下虚拟盘加密，会的给个具体步骤

Posted 2023-03-12

参考技术A LINUX下有对应的硬盘加密软件，你到软件中心去找找看吧！个人建议不要做加密，做个隐藏就行了。软件有时会出错，到时候叫你用不能用那就糟了！ 参考技术B Create one or more partitions on the drive:
cfdisk /dev/sdb
I created one big 300 GB partition, /dev/sdb1.
Setup LUKS:
cryptsetup --verbose --verify-passphrase luksFormat /dev/sdb1
Enter a good passphrase here. Don't spoil the whole endeavour by chosing a stupid or short passphrase.
Open the encrypted device and assign it to a virtual /dev/mapper/samsung300gb device:
cryptsetup luksOpen /dev/sdb1 samsung300gb
Create a filesystem on the encrypted device:
mkfs.ext3 -j -m 1 -O dir_index,filetype,sparse_super /dev/mapper/samsung300gb
I used ext3 with some optimizations, see mke2fs(8).
Mount the encrypted partition:
mkdir /mnt/samsung300gb
mount /dev/mapper/samsung300gb /mnt/samsung300gb
That's it. Everything you write to /mnt/samsung300gb will be encrypted transparently.
For unmounting use:
umount /mnt/samsung300gb
cryptsetup luksClose /dev/mapper/samsung300gb

网上抄的，大概步骤，详细的自己看下cryptsetup相关文档 参考技术C 是不是想用cryptsetup，要提供密码才能mount的那种？
