The dm-crypt system sits between the filesystem software; the filesystem software reads and writes ext4, and the ext4 data gets pushed through dm-crypt which then stores the data in LUKS format on the drive. Thus, you can effectively have a file system such as ext4 or NTFS sitting “on top of” the encrypted LUKS format.
