Encrypting USB media
Encrypting USB media is very simple, but the downside to this tutorial is that your USB drive will not work on Windows computers.
Run the following commands to set up your encrypted USB drive. This will destroy all data on the drive!
| Command | Comment |
cryptsetup luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 enc
mount /dev/mapper/enc /mnt/usb
umount /mnt/usb
cryptsetup luksClose /dev/mapper/enc |
Or name of your partition
You can change "enc" to anything you like
Choose any mount point here
You can now use /mnt/usb as usual
