Encrypting a Drive with LUKS and cryptsetup

+ +

1. Get the drive name

lsblk
+

+ +

2. Install cryptsetup

sudo pacman -S cryptsetup
+

+ +

3. Format the drive

To format the drive, you can use cfdisk or any other utility of your choice.

cfdisk /dev/sdaX
+

Now, delete all the signatures and partitions on the drive
Then, create a filesystem on the drive as follows:

mkfs.ext4 /dev/sdaX
+

After the FS has been created, create a partition on the drive with cfdisk
After the partition has been created, you can finally start encrypting the drive

+ +

4. Encrypt the created partition

List the partition

lsblk /dev/sdaX
+

Encrypt the partition

cryptsetup luksFormat /dev/sda[0-9]
+

It will ask for a passphrase, make sure to provide a strong passphrase

+ +

5. Decrypt and create filesystem

Decrypt the drive

cryptsetup open /dev/sda[0-9] <name>
+

Make the FS

mkfs.ext4 /dev/mapper/<name>
+

+ +

6. Re-encrypt after usage

cryptsetup close <name>
+

+ + + -- cgit v1.2.3
