NOTE: This article assumes that you have the necessary software installed from your GNU/Linux distribution.
- Do a "su -", or do everything here as root.
- You should have a Linux partition (hex code 83 if you use fdisk in GNU/Linux) for this purpose. Mine is "/dev/sdb1".
-
Do the following:
mkdir /encrypted
# Note: The following 2 commands will ask you for input.
cryptsetup -y -v luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 encrypted
mkfs.ext4 /dev/mapper/encrypted
mount /dev/mapper/encrypted /encrypted
-
To unmount your encrypted filesystem:
umount /encrypted
cryptsetup luksClose encrypted
-
To remount your encrypted filesystem:
# Note: The following command will ask you for input.
cryptsetup luksOpen /dev/sdb1 encrypted
mount /dev/mapper/encrypted /encrypted
