What the ...?

Cryptsetup is utility used to conveniently setup disk encryption based on DMCrypt kernel module.

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

Project also includes 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.
In contrast to existing solution, LUKS stores all setup necessary setup information in the partition header,
enabling the user to transport or migrate his data seamlessly.

Last version of the LUKS format specification is available here.


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