Stegasoo Raspberry Pi

Scripts and resources for deploying Stegasoo on Raspberry Pi.

Quick Install

On a fresh Raspberry Pi OS (64-bit) installation:

curl -sSL https://raw.githubusercontent.com/adlee-was-taken/stegasoo/main/rpi/setup.sh | bash

Or download and run manually:

wget https://raw.githubusercontent.com/adlee-was-taken/stegasoo/main/rpi/setup.sh
chmod +x setup.sh
./setup.sh

What the Setup Script Does

1. Installs system dependencies - build tools, libraries
2. Installs Python 3.12 - via pyenv (Pi OS ships with 3.13 which is incompatible)
3. Builds jpegio for ARM - patches x86-specific flags
4. Installs Stegasoo - with web UI and all dependencies
5. Creates systemd service - auto-starts on boot
6. Enables the service - ready to start

Requirements

• Raspberry Pi 4 or 5
• Raspberry Pi OS (64-bit) - Bookworm or later
• 4GB+ RAM recommended (2GB minimum)
• ~2GB free disk space
• Internet connection

After Installation

Start the Service

sudo systemctl start stegasoo

Check Status

sudo systemctl status stegasoo

View Logs

journalctl -u stegasoo -f

Access Web UI

Open in browser: http://<pi-ip>:5000

On first access, you'll create an admin account.

Configuration

Edit the systemd service to change settings:

sudo systemctl edit stegasoo

Add overrides:

[Service]
Environment="STEGASOO_AUTH_ENABLED=true"
Environment="STEGASOO_HTTPS_ENABLED=true"
Environment="STEGASOO_HOSTNAME=stegasoo.local"

Then reload:

sudo systemctl daemon-reload
sudo systemctl restart stegasoo

Uninstall

sudo systemctl stop stegasoo
sudo systemctl disable stegasoo
sudo rm /etc/systemd/system/stegasoo.service
rm -rf ~/stegasoo

Pre-built Images

Check GitHub Releases for pre-built SD card images.

Building Your Own Image

To create a distributable SD card image:

1. Flash Fresh Raspberry Pi OS

Use rpi-imager to flash Raspberry Pi OS (64-bit) to an SD card.

In advanced settings, set:

• Hostname: stegasoo
• Enable SSH (password auth for initial setup)
• Username/password (temporary, will work for any user)
• Skip WiFi for distributable image

2. Boot and Run Setup

# SSH into the Pi
ssh pi@stegasoo.local

# Run the setup script
curl -sSL https://raw.githubusercontent.com/adlee-was-taken/stegasoo/main/rpi/setup.sh | bash

3. Test It Works

sudo systemctl start stegasoo
curl -k https://localhost:5000  # Should return HTML

4. Sanitize for Distribution

# Download and run sanitize script
curl -sSL https://raw.githubusercontent.com/adlee-was-taken/stegasoo/main/rpi/sanitize-for-image.sh | sudo bash

This removes:

• WiFi credentials
• SSH authorized keys
• Bash history
• Stegasoo auth database (users create their own admin)
• Logs and temp files

5. Create the Image

After Pi shuts down, remove SD card and on another Linux machine:

# Find SD card device (BE CAREFUL - wrong device = data loss!)
lsblk

# Copy (replace sdX with your SD card)
sudo dd if=/dev/sdX of=stegasoo-rpi-$(date +%Y%m%d).img bs=4M status=progress

# Shrink the image (optional but recommended)
wget https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh
chmod +x pishrink.sh
sudo ./pishrink.sh stegasoo-rpi-*.img

# Compress
xz -9 -T0 stegasoo-rpi-*.img

6. Distribute

Upload the .img.xz file to GitHub Releases.

Users flash with:

xzcat stegasoo-rpi-*.img.xz | sudo dd of=/dev/sdX bs=4M status=progress

Or use rpi-imager's "Use custom" option.
