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}}
