dm-crypt is a transparent block device encryption subsystem in Linux kernel versions 2.6 and later and in DragonFly BSD.It is part of the device mapper (dm) infrastructure, and uses cryptographic routines from the kernel's Crypto API.
On a Linux system, the boot partition (/boot) may be encrypted if the bootloader itself supports LUKS (e.g. GRUB). This is undertaken to prevent tampering with the Linux kernel . However, the first stage bootloader or an EFI system partition cannot be encrypted (see Full disk encryption#The boot key problem ).

BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes . By default, it uses the Advanced Encryption Standard (AES) algorithm in cipher block chaining (CBC) or " xor–encrypt–xor (XEX) -based Tweaked codebook ...
Disk encryption is a technology which protects information by converting it into code that cannot be deciphered easily by unauthorized people or processes. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume.
The mount command instructs the operating system that a file system is ready to use, and associates it with a particular point in the overall file system hierarchy (its mount point) and sets options relating to its access. Mounting makes file systems, files, directories, devices and special files available for use and available to the user.
The message noted that more recent versions of Windows have built-in support for disk encryption using BitLocker, and that Linux and OS X had similar built-in solutions, which the message states renders TrueCrypt unnecessary. The page recommends any data encrypted by TrueCrypt be migrated to other encryption setups and offered instructions on ...
Mount points can be created in a directory on an NTFS file system, which gives a reference to the root directory of the mounted volume. Any empty directory can be converted to a mount point. The mounted volume is not limited to the NTFS filesystem but can be formatted with any file system supported by Microsoft Windows.
