HushBox

The idea is to get rid of both hardware and software backdoors, install all necessary tools on a Pi 4 and sell it as a plug-and-play device. Including shipping cost the total estimated price is 250 USD, we accept HUSH only. If you have Raspberry Pi 4 already you can just follow the guide.

HushBox includes the following:

• Raspberry Pi 4 model b with 4GB of RAM.
• Devuan GNU+Linux, a fork of Debian without systemd, but sysvinit.
• Hush cryptocurrency and HushChat.
• Hush full node software.
• The Invisible Internet Project I2P.

Devuan GNU+Linux

Download the latest image and its hash from arm-files.devuan.org

curl https://arm-files.devuan.org/RaspberryPi%20Latest%20Builds/rpi-4-<choose-the-latest>.zip --output devuan.zip 
curl https://arm-files.devuan.org/RaspberryPi%20Latest%20Builds/rpi-4-<choose-the-latest>.zip.sha256sum --output sha256sum 

Verify the integrity of the file by comparing the hash value.

cat sha256sum
sha256sum devuan.zip
unzip devuan.zip

MicroSD card is needed to image the file, change 5.10.82-v8-ext4-2021-12-05 and mmcblk1 to whatever you have, use ls and lsblk to check it. Unmount SD card and if it has more than one partition, you will need to unmount each partition.

• Substitute the microSD for a real USB hard drive as the Raspberry Pi 4 8GB model supports booting directly off USB. If you're using a Pine64 Rock64 board, then it gets more complicated and requires you to flash some new firmware to enable USB boot.

sudo umount /dev/mmcblk1
sudo dd if=rpi-4-devuan-beowulf-5.10.82-v8-ext4-2021-12-05.img of=/dev/mmcblk1 

Now install the desktop environment, XFCE in this case.

sudo apt-get install xfce4-panel xfdesktop4 xfwm4 xfce4-settings xfce4-session xfce4-terminal xfce4-appfinder xfce4-power-manager thunar ristretto blackbird-gtk-theme papirus-icon-theme slim xinit firefox-esr fonts-liberation webext-ublock-origin -y 

(Optional) Install the necessary packages to support auto-mounting of drives.

sudo apt-get install thunar-volman gvfs policykit-1 -y 

Run update-alternatives to set the x-session-manager to xfce4-session.

sudo update-alternatives --config x-session-manager

Start XFCE, you run it only once.

startxfce4

(Optional) To enable Mobile tether you need to uncomment allow-hotplug usb0 and iface usb0 inet dhcp strings:

sudo vi /etc/network/interfaces

### Mobile tether
allow-hotplug usb0
iface usb0 inet dhcp

Notes

xfce4-terminal --hide-menubar --hide-scrollbar --hide-toolbar

Compile Qt 5.15.2 from source

Remove & purge all Qt packages

sudo apt -y remove qt5* libqt5* qtcreator && sudo apt autoremove -y 

Download Qt 5.15.2 Source to qt5-sources folder

mkdir qt5-sources && cd qt5-sources && mkdir build-shadow
wget https://download.qt.io/official_releases/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz

Make the configuration (-j 4 is number of cpus you want to use)

make -j 4

Install Qt5 into: (default) /usr/local/

sudo make install

Update profile to know where Qt5.15.2 bins are

nano ~/.bashrc

Add this at the bottom of your .bashrc file.

# set PATH for Qt 5.15.2
export PATH="/usr/local/Qt-5.15.2/bin:$PATH"

Reload your ~/.bashrc file & create a new shell window.

source ~/.bashrc
exit

Verify Qt 5.15.2 has been installed

qmake --version

HushChat

To use HushChat we need to install Rust first.

curl --proto '=https' --tlsv1.3 -sSf https://sh.rustup.rs | sh -s -- -y && exit

Then install SilentDragonLite.

git clone https://git.hush.is/hush/SilentDragonLite.git && cd SilentDragonLite/util && ./install.sh
