## What you will need 📋
* A USB drive
* A computer with Linux 🐧🖥
* The ability to read instructions and to follow them 🧠
* * *
1) Install cryptsetup
> $ sudo pacman -S cryptsetup
* * *
2) Backup any information on the USB stick because this process involves formatting the USB drive.
* * *
3) Formatting USB.
> $ sudo fdisk /dev/sdX
The X being your USB drive.
Press the following keys:
o
n
Press enter for the rest
w
* * *
4) Encryption time!
> $ sudo cryptsetup luksFormat /dev/sdX1
* * *
5) Decrypt USB
> $ sudo cryptsetup luksOpen /dev/sdX1 USB
Note: The first password is your root user password, not the encryption password. I have sadly made this mistake in the past.
* * *
6) Format the Encrypted Partition
> $ sudo mkfs.ext4 /dev/mapper/USB
Depending on the size of the USB, this may take some time. For me, it took 3 minutes.
* * *
Step 7: Mount the Encrypted Partition
> $ sudo mkdir -p /mnt/USB <hr>
> $ sudo mount /dev/mapper/USB /mnt/USB
* * *
## Finished ✅
I hope your password is good, make sure to memorize it or save it in a password manager!
