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
