Using the Secure Viewing Station

Moving Documents to the Secure Viewing Station

Step 1: Download the encrypted submission

Documents and messages sent by sources can only be decrypted and viewed on the Secure Viewing Station. After clicking on an individual source, you will see a page with any documents or messages the source has sent you. Documents always end with -doc.gz.gpg, while messages always end with -msg.gpg.

Click on a document or message name to save it, or select a number of documents and save them all at once by clicking Download Selected.

Example source page displaying two files: a document and a message, both selected. A button 'Download Selected' is visible above the list of files.

A dialog box with two choices will appear, Cancel and Save file.

Dialog box asking for confirmation before saving a file.

Click Save file. In the save dialog, select one of the two folders called Tor Browser and Tor Browser (persistent). Note that the names may be abbreviated; you can view the full name by hovering the mouse over the shortcut.

The difference between these two folders is as follows:

  • Tor Browser: Downloads saved to this folder will be stored in memory, which means that they will only be available for the duration of your current Tails session. The full path to this folder is /home/amnesia/Tor Browser.

  • Tor Browser (persistent): Downloads saved to this folder will be stored on your Tails USB drive in the special persistent volume that is only available if you have unlocked it on the Tails welcome screen. The full path to this folder is /home/amnesia/Persistent/Tor Browser.

Unless you have a reason to store encrypted submissions on the Journalist Workstation, we recommend using the non-persistent “Tor Browser” folder. In the recommended process, you will now move the submission to the Secure Viewing Station, and there is no need to leave a persistent copy behind.

Important

Attempting to download files to any other folder will fail. Tails only permits Tor Browser to access these two folders, so that even if your browser is compromised by malware, attackers cannot easily gain access to other data stored on the same computer.

See the Tails guide to Browsing the web with Tor Browser for more information.

Step 2: Copy the encrypted submission to the Transfer Device

Once downloaded to either folder, move the document to the designated USB stick you intend to use to transfer the documents from your Journalist Workstation to the Secure Viewing Station. This storage device is known as your Transfer Device.

Note

If the Transfer Device was set up according to our recommendations, you

will be prompted for a decryption passphrase on the Journalist Workstation and the Secure Viewing Station before being able to use it in a given session. We recommend storing this passphrase in your own personal password manager (e.g., on your smartphone), so that it is readily accessible to you whenever you need it.

You can right-click the file and select Copy to, then select the Transfer Device in the Select Copy Destination dialog.

Dialog box that opens after selecting 'Copy to', the Transfer Device is selected in the list of places on the left.

This will leave a redundant copy behind in the Tor Browser folder. If you have downloaded the file to the non-persistent “Tor Browser” folder (as recommended), the redundant copy will disappear when the computer is shut down or rebooted.

“Eject” the Transfer Device by clicking the eject icon next to its name in the file manager. Wait for this operation to complete (the eject icon will disappear), then unplug the Transfer Device. “Ejecting” the drive in this manner ensures that all write operations are completed before you physically unplug it.

Step 3: Decrypt and view the submission on the Secure Viewing Station

Next, boot up the Secure Viewing Station using Tails and enter the passphrase for the Secure Viewing Station persistent volume. Once you have logged in, plug in the Transfer Device.

Note

The Secure Viewing Station and Journalist Workstation are on separate Tails USB drives.

Click on the Home icon on your desktop, then on the Transfer Device. Copy the file into your Persistent folder. You can do so by opening a new window with the Persistent folder and dragging the file from one window to another. A faster method is to drag the file to the Persistent shortcut in the list of places.

Important

Always copy submissions to the Persistent folder before decrypting them. Otherwise you might accidentally decrypt them on the USB stick, and they could be recoverable in the future.

After successfully copying them to the Secure Viewing Station, erase the files from your Transfer Device. Ensure you’re viewing the Transfer Device folder, then right click on the files that need removal and click “Move to Trash”, then navigate to “Trash” folder in the sidebar, and select “Empty Trash”.

To decrypt and view documents or messages, return to your Persistent folder. All key actions are initiated by double-clicking:

  • Double-clicking archives in ZIP or gzip format will open the Archive Manager application (called file-roller on the command line), which allows you to extract the contents.

  • On Tails 4, double-clicking files that end in .gpg will attempt to decrypt the contents to the same directory. If you have configured a passphrase for your Submission Key, you will be prompted for it.

    On Tails 5.1 or greater, double-clicking the .gpg file will launch an application called Kleopatra, from which you can decrypt the file and save the result to the same directory.

  • Double-clicking decrypted messages or documents will attempt to open them in a default application suitable for the file type.

If the default application does not work, you can right-click on the document and choose Open with Other Application… to try opening the document with LibreOffice Writer, Document Viewer, or another application. You might also need to right-click on a file and choose Rename… to rename a document with an incorrect or missing file extension.

Tip

Always extract gzip archives with the Archive Manager application, which is the default when double-clicking the archive. Other methods may not preserve the filename contained in the archive.

For example, an archive called 1-artful_elevation-doc.gz might contain a file secrets.docx, but if you extract the contents by right-clicking the archive and selecting Extract here, the extracted file will be called 1-artful_elevation-doc instead of secrets.docx. This may result in problems when attempting to open the file due to the loss of its file extension.

When you double-click an archive to open it, you should see it in the Archive Manager application.

Click the Extract button to unpack the archive. Navigate to the folder containing the encrypted document message or document (ends with .gpg).

Double-click the file to decrypt it. On Tails 5.1 or greater, this will launch Kleopatra, from which you can decrypt the file and save the result to the same directory.

The decrypted file will have the same filename, but without .gpg at the end.

You can now double-click on the decrypted file to open it in its default application.
