What the ...?
=============
**Cryptsetup** is a utility used to conveniently set up disk encryption based
on the [DMCrypt](https://gitlab.com/cryptsetup/cryptsetup/wikis/DMCrypt) kernel module.

These include **plain** **dm-crypt** volumes, **LUKS** volumes, **loop-AES**,
**TrueCrypt** (including **VeraCrypt** extension) and **BitLocker** formats.

The project also includes a **veritysetup** utility used to conveniently setup
[DMVerity](https://gitlab.com/cryptsetup/cryptsetup/wikis/DMVerity) block integrity checking kernel module
and, since version 2.0,  **integritysetup** to setup
[DMIntegrity](https://gitlab.com/cryptsetup/cryptsetup/wikis/DMIntegrity) block integrity kernel module.


LUKS Design
-----------
**LUKS** is the standard for Linux hard disk encryption. By providing a standard on-disk-format, it does not  
only facilitate compatibility among distributions, but also provides secure management of multiple user passwords.  
LUKS stores all necessary setup information in the partition header, enabling to transport or migrate data seamlessly.

Last version of the LUKS2 format specification is
[available here](https://gitlab.com/cryptsetup/LUKS2-docs).

Last version of the LUKS1 format specification is
[available here](https://www.kernel.org/pub/linux/utils/cryptsetup/LUKS_docs/on-disk-format.pdf).

Why LUKS?
---------
 * compatibility via standardization,
 * secure against low entropy attacks,
 * support for multiple keys,
 * effective passphrase revocation,
 * free.
