🔧 Installation

1. Upload all files (index.html, sender.html, receiver.html, signal.php, css, img) to your web server
2. Ensure PHP and HTTPS is enabled (⚠️ PHP 7.4 or higher and TLS/HTTPS required)
3. Make sure the server allows writing to the /signals directory (created automatically and protected with .htaccess)
4. Share the Stream ID or the Receiver link with your viewer

---

⚙️ How It Works

• Sender opens sender.html and starts the stream → a new random Stream ID is created.
• Receiver opens receiver.html and enters the same Stream ID.
• Both communicate via the signaling server (signal.php), which exchanges:
  • 📤 Offers & Answers (SDP)
  • ❄️ ICE candidates (STUN connectivity)
  • 🚫 Bye messages (to end streams)
• Once connected, the video/audio stream flows directly peer-to-peer (encrypted).

---

🔒 Security

• All signaling data is stored as temporary JSON files on the server (auto-deleted after 24h).
• Access to the /signals directory is blocked via .htaccess.
• Media streams are end-to-end encrypted by WebRTC.
• Stream IDs are random 6-digit numbers and expire after stream termination.
