# systemd-cryptsetup
|
|
|
|
> Create or remove decrypted mappings of encrypted volumes. Equivalent of `cryptsetup open` and `cryptsetup close`.
|
|
> Arguments to this command are written exactly like a line in `/etc/crypttab`. It's used by systemd to unlock devices on boot.
|
|
> See also: `cryptsetup`.
|
|
> More information: <https://www.freedesktop.org/software/systemd/man/latest/systemd-cryptsetup.html>.

- Open a LUKS volume and create a decrypted mapping at `/dev/mapper/mapping_name`:
|
|
|
|
`systemd-cryptsetup attach {{mapping_name}} {{/dev/sdXY}}`
|
|
|
|
- Open a LUKS volume with additional options and create a decrypted mapping at `/dev/mapper/mapping_name`:
|
|
|
|
`systemd-cryptsetup attach {{mapping_name}} {{/dev/sdXY}} none {{crypttab_options}}`
|
|
|
|
- Open a LUKS volume with a keyfile and create a decrypted mapping at `/dev/mapper/mapping_name`:
|
|
|
|
`systemd-cryptsetup attach {{mapping_name}} {{/dev/sdXY}} {{path/to/keyfile}} {{crypttab_options}}`
|
|
|
|
- Remove an existing mapping:
|
|
|
|
`systemd-cryptsetup detach {{mapping_name}}`
