What is [Signal]?
|
|
|
|
[According to Wikipedia:][signal-wikipedia]
|
|
|
|
> Signal is an encrypted instant messaging and voice calling application
|
|
> for Android and iOS. It uses end-to-end encryption to secure all
|
|
> communications to other Signal users. Signal can be used to send and receive
|
|
> encrypted instant messages, group messages, attachments and media messages.
|
|
> Users can independently verify the identity of their messaging correspondents
|
|
> by comparing key fingerprints out-of-band. During calls, users can check the
|
|
> integrity of the data channel by checking if two words match on both ends of
|
|
> the call.
|
|
>
|
|
> Signal is developed by Open Whisper Systems. The clients are published as free
|
|
> and open-source software under the GPLv3 license.

How to install Signal in Qubes
|
|
------------------------------
|
|
|
|
If you're a Signal user on Android, you can now have Signal inside Qubes.
|
|
|
|
1. Install the Chromium browser in a TemplateVM.
|
|
2. Shut down the TemplateVM.
|
|
3. Create a new AppVM based on this TemplateVM.
|
|
4. Launch Chromium browser in the new AppVM, type `chrome://extensions/` in the
|
|
address bar, and follow the link to the Chrome app store.
|
|
4. In the app store, search for "Signal Private Messenger" and install the app.
|
|
5. The app launches automatically on first install. Follow the prompts to "link"
|
|
this app with your phone.
|
|
6. Signal should now work in your AppVM.
|
|
|
|
Creating a Shortcut in the applications menu
|
|
--------------------------------------------
|
|
|
|
Let's make Signal a bit more usable by creating a shortcut in our desktop
|
|
panel that launches Signal directly. This assumes that you're using KDE or Xfce in Dom0,
|
|
you use Signal in an AppVM named `Signal`, and this AppVM uses `fedora-23` as its TemplateVM.
|
|
|
|
1. Follow [these instructions][shortcut] to create a desktop shortcut on the Desktop of your Signal AppVM.
|
|
Let's assume the shortcut file you get is `/home/user/Desktop/chrome-bikioccmkafdpakkkcpdbhpfkkhcmohk-Default.desktop`
|
|
2. Copy this shortcut file to the AppVM's TemplateVM - in this case, to `fedora-23`.
|
|
|
|
[user@Signal ~]$ qvm-copy-to-vm fedora-23 /home/user/Desktop/chrome-bikioccmkafdpakkkcpdbhpfkkhcmohk-Default.desktop
|
|
|
|
3. You'll also want to copy across an icon for your new shortcut - you can find this at
|
|
`/home/user/.local/share/icons/hicolor/48x48/apps/chrome-bikioccmkafdpakkkcpdbhpfkkhcmohk-Default.png`
|
|
Copy this icon to the `fedora-23` TemplateVM in the same way as step 2.
|
|
4. Open a terminal in your `fedora-23` TemplateVM and `cd` to `/home/user/QubesIncoming/Signal/`.
|
|
You should find your shortcut and icon files just transferred across from the Signal AppVM.
|
|
Move these files to the following locations:
|
|
|
|
[user@fedora-23 Signal]$ sudo mv chrome-bikioccmkafdpakkkcpdbhpfkkhcmohk-Default.desktop /usr/share/applications/
|
|
[user@fedora-23 Signal]$ sudo mv chrome-bikioccmkafdpakkkcpdbhpfkkhcmohk-Default.png /usr/share/icons/hicolor/48x48/apps/
|
|
|
|
5. From a Dom0 terminal, instruct Qubes to synchronize the application menus of this TemplateVM:
|
|
|
|
[user@dom0 ~]$ qvm-sync-appmenus fedora-23
|
|
|
|
6. Stop both the AppVM (`Signal`) and its TemplateVM (`fedora-23`).
|
|
The `Signal` VM will now see the desktop file in `/usr/share/applications` when it is next started.
|
|
|
|
7. With your mouse select the `Q` menu -> `Domain: Signal` -> `Signal: Add more shortcuts`
|
|
Select `Signal Private Messenger` from the left `Available` column, move it to the right `Selected` column by clicking the `>` button and then `OK` to apply the changes and close the window.
|
|
8. (optional, only on KDE:) Follow the `Q` menu once more, right-click on the new `Signal: Signal Private Messenger` menu item and select `Add to Panel`.
|
|
|
|
You can now launch the Signal messenger inside its own dedicated AppVM directly from the desktop.
|
|
|
|
The same steps should work for any Chrome app.
