1 [[!meta title="Create and use encrypted volumes"]]
3 The simplest way to carry around the documents you want to use with Tails and
4 make sure that they haven't been accessed nor modified is to store them in an
5 encrypted volume: a dedicated partition on a USB stick or an external hard-disk.
7 Tails comes with utilities for LUKS, a standard for disk-encryption under Linux.
9 - The GNOME <span class="application">Disk Utility</span>, allows you to
10 create encrypted volumes.
11 - The GNOME desktop, allows you to open encrypted volumes.
15 <p>To store encrypted files on a Tails device, it is recommended to create a
16 [[persistent volume|first_steps/persistence]] instead.</p>
23 privileges|first_steps/startup_options/administration_password]] are required to
24 modify the list of partitions on the USB stick or SD card from which Tails is
31 Create an encrypted partition
32 =============================
34 To open the GNOME <span class="application">Disk Utility</span> choose
35 <span class="menuchoice">
36 <span class="guimenu">Applications</span> ▸
37 <span class="guisubmenu">Accessories</span> ▸
38 <span class="guimenuitem">Disk Utility</span></span>.
40 <h2 class="bullet-number-one">Identify your external storage device</h2>
42 <span class="application">Disk Utility</span> lists all the current storage
43 devices on the left side of the screen.
45 1. Plug in the external storage device that you want to use.
47 1. A new device appears in the list of storage devices. Click on it:
49 [[!img storage_devices_after.png link=no alt="A new storage device appeared
52 <h2 class="bullet-number-two">Format the device</h2>
54 1. Check that the description of the device on the right side of the screen
55 corresponds to your device: its brand, its size, etc.
57 1. Click on <span class="guilabel">Format Drive</span> to erase all the
58 existing partitions on the device.
60 1. In the dialog box to select the <span class="guilabel">Scheme</span>, if
61 you are unsure, leave the default option <span class="guilabel">Master Boot
62 Record</span> selected.
64 <h2 class="bullet-number-three">Create a new encrypted partition</h2>
66 Now the schema of the partitions in the middle of the screen shows an empty
69 [[!img empty_device.png link=no alt="Free 3.9 GB"]]
71 1. Click on <span class="guilabel">Create Partition</span>.
73 1. Configure the new partition:
75 [[!img create_partition.png link=no alt="Create partition on…"]]
77 - <span class="guilabel">Size</span>. You can decide to create a partition
78 on the whole device or just on part of it. In this example we are creating
79 a partition of 2.0 GB on a device of 3.9 GB.
80 - <span class="guilabel">Type</span>. You can change the file system type of
81 the partition. If you are not sure you can leave the default value:
82 <span class="guilabel">Ext4</span>.
83 - <span class="guilabel">Name</span>. You can set a name for the partition.
84 This name remains invisible until the partition is open but can help
85 you to identify it during use.
86 - <span class="guilabel">Encrypt underlying device</span>. Select this
87 option to encrypt the partition.
89 Then click on the <span class="button">Create</span> button.
91 1. Enter a passphrase for the new partition in the
92 <span class="guilabel">Enter passphrase</span> dialog box. Then click on
93 the <span class="button">Create</span> button.
95 1. Creating the partition takes from a few seconds to a few minutes. After
96 that, the new encrypted partition appears in the volumes of the device:
98 [[!img encrypted_partition.png link=no alt="Encrypted 2.0 GB / secret 2.0 GB ext4"]]
100 1. At this point you can create other partitions in the free space left on the
101 device, if you want, by clicking on it and doing again
102 <span class="guilabel">Create Partition</span>.
104 <h2 class="bullet-number-four">Use the new partition</h2>
106 You can access this new volume from the <span class="guimenu">Places</span> menu
107 with the name you gave it.
109 [[!img places_secret.png link=no alt="Places ▸ secret"]]
111 Open an existing encrypted partition
112 ====================================
114 When plugging a device containing an encrypted partition, Tails does not mount it
115 automatically but it appears in the <span class="guimenu">Places</span>
116 menu. If several partitions appear as <span class="guimenu">Encrypted</span>,
117 like in the example, you can use its size to guess which one is the one you want
120 [[!img places_encrypted.png link=no alt="Places ▸ 2.0 GB Encrypted"]]
122 Once you are done using the device, to close the encrypted partition choose
123 <span class="menuchoice">
124 <span class="guimenu">Places</span> ▸
125 <span class="guisubmenu">Computer</span></span>,
126 right-click on the device, and select <span class="guilabel">Safely
