In this section, the guide shows you how to mount/unlock an encrypted disk.
To unlock disk, you simply use luksOpen argument followed by the encrypted disk and the LUKS mounting name. The syntax is as follows:
$ cryptsetup luksOpen /dev/<device name> <mounting name>
Example:
$ cryptsetup luksOpen /dev/sda sda_crypt
Once mounted, you should see a new device inside the mapper section with the mounting name, such that:
/dev/mapper/<mounting name>
If we follows the example above, it is:
/dev/mapper/sda_crypt
That's all for cryptsetup disk mounting.
