The shrinking is only for faster image downloads. After flashing,
the image should auto-expand to fill the SD card.

Stegasoo v4.1.5

Developer Experience

  • Educational Code Comments: Core modules now include detailed explanations
    • DCT: zig-zag coefficient diagrams, QIM embedding math, Reed-Solomon "Voyager" reference
    • LSB: visual bit manipulation examples, ChaCha20 pixel selection
    • Crypto: multi-factor KDF flow diagrams, Argon2id memory-hardness reasoning
    • CLI/Web: architectural patterns for future contributors

Raspberry Pi Improvements

  • Streamlined Image Creation: pull-image.sh now handles everything
    • Auto-resizes rootfs to exactly 16GB (for smaller download)
    • Preserves auto-expand (image fills SD card on first boot)
    • Compresses with zstd
    • Optional .zst.zip wrapper for GitHub releases
  • 16GB Minimum: Pre-built images are now 16GB (was variable)
  • Host Requirements: rpi/host-requirements.txt documents all dependencies
  • Test Automation: kickoff-pi-test.sh for one-command flash+test cycles

MOTD Polish

  • Dynamic temperature emoji (ice/cool/fire based on CPU temp)
  • Rocket emoji for service status
  • Cleaner formatting

Raspberry Pi Image

Download stegasoo-rpi-4.1.5.img.zst.zip from Releases.

# Flash (auto-detects SD card)
sudo ./rpi/flash-image.sh stegasoo-rpi-4.1.5.img.zst.zip

# Or manual
zstdcat stegasoo-rpi-4.1.5.img.zst | sudo dd of=/dev/sdX bs=4M status=progress

Default login: admin / stegasoo

First boot runs the setup wizard for WiFi, HTTPS, and channel key configuration.

Docker

docker-compose up -d web  # Web UI on :5000
