<title>LUKS-Encrypted File Systems</title>

|
NixOS supports file systems that are encrypted using
|
|
<emphasis>LUKS</emphasis> (Linux Unified Key Setup). For example, here is how
|
|
you create an encrypted Ext4 file system on the device
|
|
<filename>/dev/disk/by-uuid/3f6b0024-3a44-4fde-a43a-767b872abe5d</filename>:
|
|
<screen>
|
|
# cryptsetup luksFormat /dev/disk/by-uuid/3f6b0024-3a44-4fde-a43a-767b872abe5d
|
|
|
|
WARNING!
|
|
========
|
|
This will overwrite data on /dev/disk/by-uuid/3f6b0024-3a44-4fde-a43a-767b872abe5d irrevocably.
|
|
|
|
Are you sure? (Type uppercase yes): YES
|
|
Enter LUKS passphrase: ***
|
|
Verify passphrase: ***
|
|
|
|
# cryptsetup luksOpen /dev/disk/by-uuid/3f6b0024-3a44-4fde-a43a-767b872abe5d crypted
|
|
Enter passphrase for /dev/disk/by-uuid/3f6b0024-3a44-4fde-a43a-767b872abe5d: ***
|
|
|
|
# mkfs.ext4 /dev/mapper/crypted
|
|
</screen>
|
|
To ensure that this file system is automatically mounted at boot time as
|
|
<filename>/</filename>, add the following to
|
|
<filename>configuration.nix</filename>:
|
|
<programlisting>
|
|
<link linkend="opt-boot.initrd.luks.devices._name__.device">boot.initrd.luks.devices.crypted.device</link> = "/dev/disk/by-uuid/3f6b0024-3a44-4fde-a43a-767b872abe5d";
|
|
<xref linkend="opt-fileSystems"/>."/".device = "/dev/mapper/crypted";
|
|
</programlisting>
|
|
Should grub be used as bootloader, and <filename>/boot</filename> is located
|
|
on an encrypted partition, it is necessary to add the following grub option:
|
|
<programlisting><xref linkend="opt-boot.loader.grub.enableCryptodisk"/> = true;</programlisting>
