# Tor Browser Automation

Headless browser automation with Tor SOCKS5 proxy support for accessing `.onion` sites and anonymous web browsing.

## Prerequisites

- Tor service running with SOCKS5 proxy on port 9050
- Python 3.8+
- Playwright with Chromium browser

Quick setup:
```bash
# Install Tor
sudo apt install tor && sudo systemctl start tor

# Install Python dependencies
pip install playwright
playwright install chromium
```

## Quick Start

```bash
# Check Tor connection
tor-browser check-tor

# Navigate to a .onion site
tor-browser open http://3g2upl4pq6kufc4m.onion

# Get page snapshot
tor-browser snapshot -i

# Click an element
tor-browser click @e1

# Take screenshot
tor-browser screenshot -o output.png --full
```

## Commands

### Navigation

```bash
# Open URL via Tor
tor-browser open <url> [--proxy socks5://host:port]

# Check Tor connection status
tor-browser check-tor
```

### Page Analysis

```bash
# Get full page snapshot
tor-browser snapshot

# Get interactive elements only (forms, buttons, links)
tor-browser snapshot -i

# Extract all links
tor-browser links

# Get page text
tor-browser gettext
tor-browser gettext --ref @e5
```

### Interaction

```bash
# Click element by ref
tor-browser click @e1

# Fill input field
tor-browser fill @e2 "text to enter"

# Wait for page load
tor-browser wait 2000
```

### Screenshots

```bash
# Take viewport screenshot
tor-browser screenshot

# Save to file
tor-browser screenshot -o capture.png

# Full page screenshot
tor-browser screenshot --full -o page.png
```

## Python API

```python
from scripts.tor_browser import TorBrowser, Config
import asyncio

async def main():
    # Configure browser
    config = Config(
        tor_proxy="socks5://127.0.0.1:9050",
        headless=True,
        timeout=30000
    )
    
    # Initialize and start
    browser = TorBrowser(config)
    await browser.start()
    
    # Navigate
    result = await browser.navigate("http://3g2upl4pq6kufc4m.onion")
    print(f"Loaded: {result['title']}")
    
    # Get snapshot
    snapshot = await browser.get_snapshot(interactive_only=True)
    for elem in snapshot['elements']:
        print(f"{elem['ref']}: {elem['tag']} - {elem['text'][:30]}")
    
    # Interact
    await browser.fill("@e2", "search query")
    await browser.click("@e3")
    
    # Extract data
    links = await browser.extract_links()
    for link in links:
        print(f"{link['text']}: {link['href']}")
    
    # Cleanup
    await browser.close()

asyncio.run(main())
```

## Configuration Options

| Option | Default | Description |
|--------|---------|-------------|
| `tor_proxy` | `socks5://127.0.0.1:9050` | Tor SOCKS5 proxy URL |
| `headless` | `true` | Run without GUI |
| `timeout` | `30000` | Page load timeout (ms) |
| `user_agent` | Tor Browser UA | Browser user agent |
| `viewport` | `1920x1080` | Browser viewport size |

## Security & Legal

**Intended Use:**
- Security research and threat intelligence
- Anonymous web scraping of public dark web resources
- Testing .onion site accessibility
- Privacy-preserving web automation

**Important:**
- Only use for legal purposes
- Respect site Terms of Service
- Do not use for unauthorized access
- Comply with local laws regarding dark web access
- Be aware that some activities may be monitored

## Troubleshooting

### Tor Connection Issues

```bash
# Check Tor is running
sudo systemctl status tor

# Test SOCKS5 proxy
curl --socks5-hostname 127.0.0.1:9050 https://check.torproject.org/api/ip

# View Tor logs
sudo journalctl -u tor -f
```

### Common Errors

**Connection refused:**
- Ensure Tor service is started
- Check firewall rules
- Verify proxy URL

**Timeout:**
- .onion sites may be slow; increase timeout
- Try different Tor circuits: restart Tor service

**CAPTCHA blocking:**
- Use `--headed` mode to manually solve
- Some sites block automation

## Docker Setup

```dockerfile
FROM python:3.11-slim

RUN apt-get update && apt-get install -y tor
RUN pip install playwright && playwright install chromium

COPY . /app
WORKDIR /app

CMD ["tor-browser", "check-tor"]
```
