What the ...?

Cryptsetup is a utility used to conveniently set up disk encryption based on the 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 block integrity checking kernel module and, since version 2.0, integritysetup to setup 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.

Last version of the LUKS1 format specification is available here.

Why LUKS?

  • compatibility via standardization,
  • secure against low entropy attacks,
  • support for multiple keys,
  • effective passphrase revocation,
  • free.
