Using DMCrypt to create, create an encrypted filesystem, mappable and mountable filesystem and mount same.
Using DMCrypt to create an encrypted partition on your thumbdrive.
Remove all partitions from the current ThumbDrive:
parted -s ‘rm 1’ DEVICE
Find partitionable size:
~$ sudo fdisk -l /dev/sdc | grep bytes | head -1 | sed ‘s/^.* \([0123456789]*\) bytes/\1 \/ 1000000/’ | bc
16039
Partition the ThumbDrive:
parted -s ‘mkpart primary 0 16039’ DEVICE
Create the DeviceMapper device:
sudo cryptsetup create NAME DEVICE
passphrase:
Make a filesystem on the mapped device (non-journaled FS’s only):
mke2fs /dev/mapper/NAME
Mount the filesystem where appropriate:
mount /dev/mapper/NAME /map-point
