# cryptsetup
> Manage plain dm-crypt and LUKS (Linux Unified Key Setup) encrypted volumes.
- Initialize a LUKS volume (overwrites all data on the partition):
`cryptsetup luksFormat {{/dev/sda1}}`
- Open a LUKS volume and create a decrypted mapping at /dev/mapper/{{target}}:
`cryptsetup luksOpen {{/dev/sda1}} {{target}}`
- Remove an existing mapping:
`cryptsetup luksClose {{target}}`
- Change the LUKS volume's passphrase:
`cryptsetup luksChangeKey {{/dev/sda1}}`
