luksformat - Create and format an encrypted LUKS device
luksformat [-t fstype] device [ mkfs options ]
luksformat is a wrapper around cryptsetup and mkfs which provides an easy interface for creating an encrypted device that follows the LUKS standard and for putting a file system onto the encrypted device.
The default file system is vfat since that is most commonly used on removable devices. However, you can specify any available file system with the -t option.
