Air-Gapped Deployment

OpenFOIA can run completely offline on an air-gapped machine -- no network connection required after initial setup. This guide covers the overall approach and links to platform-specific instructions.

Why Air-Gap?

An air-gapped deployment means the machine running OpenFOIA has no network connection. This eliminates:

  • Remote exfiltration of your FOIA data
  • Network-based surveillance of your research activity
  • Accidental data leaks through telemetry, DNS, or background services

It is the strongest operational security posture available.

Quick Start

1. Prepare an Encrypted USB

See USB.md for detailed instructions on creating an encrypted USB with LUKS, VeraCrypt, or a macOS encrypted disk image.

2. Install OpenFOIA Offline

On an online machine, download the packages:

mkdir openfoia-offline
pip download openfoia -d openfoia-offline/

Copy the openfoia-offline/ directory to the encrypted USB.

On the air-gapped machine:

python3 -m venv /path/to/usb/venv
source /path/to/usb/venv/bin/activate
pip install --no-index --find-links=/path/to/usb/openfoia-offline openfoia

3. Set the Data Directory

export OPENFOIA_DATA_DIR="/path/to/usb/data"
openfoia init --password YOUR_SECRET

4. Transfer Documents via Sneakernet

  1. On the online machine, download FOIA response documents.
  2. Copy them to the encrypted USB.
  3. On the air-gapped machine, ingest them:
openfoia docs ingest /path/to/usb/incoming/response.pdf

5. Send Requests via Sneakernet

  1. Draft requests on the air-gapped machine: 
    openfoia request new --agency FBI --subject "..." --name "..." --email "..."
  2. Export the request text to a file on the USB.
  3. On the online machine, send via email/fax/mail.

Platform-Specific Guides

Platform Guide Notes
Tails OS TAILS.md Debian-based live OS with built-in Tor. Ideal for journalist work.
Encrypted USB USB.md Portable install on LUKS/VeraCrypt/macOS encrypted volume.
Any Linux This document Follow the quick start above.

Key Configuration

OPENFOIA_DATA_DIR

The most important setting for air-gapped deployments. This environment variable tells OpenFOIA where to store all data (database, documents, exports, config). Set it to a path on your encrypted USB or persistent volume:

export OPENFOIA_DATA_DIR="/mnt/encrypted-usb/openfoia"

Without this variable, OpenFOIA defaults to ~/.openfoia/ in the user's home directory.

Database Encryption

Even on an encrypted volume, enabling SQLCipher adds a second layer:

pip install 'openfoia[encryption]'
openfoia init --password YOUR_SECRET

Duress Mode

openfoia init --password YOUR_SECRET --duress-password INNOCENT_PASSWORD

If compelled to open OpenFOIA, use the duress password to reveal only a decoy database with bland FOIA requests about weather data and park statistics.

AI/LLM on Air-Gapped Machines

OpenFOIA supports Ollama for local LLM inference. On an air-gapped machine:

  1. Download the Ollama binary and a model (e.g., llama3.2) on an online machine.
  2. Transfer to the air-gapped machine via USB.
  3. Run Ollama locally -- no internet required.
ollama serve &
openfoia config --init  # Select "ollama" as the AI provider

Security Checklist

  • Air-gapped machine has no WiFi/Ethernet/Bluetooth enabled
  • USB drive is encrypted (LUKS, VeraCrypt, or hardware encryption)
  • OPENFOIA_DATA_DIR points to the encrypted volume
  • Database encryption enabled (--password)
  • Duress mode configured (--duress-password)
  • Swap disabled or encrypted on the air-gapped machine
  • Ollama running locally for AI features (no cloud API keys)
  • Physical security of the USB drive when not in use
