SnapQRpy 0.2.0

Advanced QR-based screen sharing and remote control system with consent management

SnapQRpy

SnapQRpy is an advanced Python library for QR-based screen sharing and remote device control with comprehensive consent management.

Overview

SnapQRpy provides a secure, efficient, and user-friendly way to share screens and control devices remotely using QR code technology. The library supports multiple platforms including Android, iOS, Windows, macOS, and Linux.

Key Features

• QR Code Generation: Create dynamic QR codes for instant device pairing
• Screen Sharing: Real-time screen mirroring with low latency
• Remote Control: Control devices with explicit user consent
• End-to-End Encryption: Military-grade encryption for all communications
• Cross-Platform: Works on Android, iOS, Windows, macOS, and Linux
• Consent Management: Built-in permission system for user authorization
• WebRTC Support: Peer-to-peer connections for optimal performance
• Multi-Protocol: Support for WebSocket, HTTP/2, gRPC, and more
• Plugin System: Extensible architecture for custom functionality
• Rate Limiting: Protect against abuse with configurable limits
• Session Management: Secure session handling with automatic timeout
• Logging & Analytics: Comprehensive logging and performance metrics

Installation

Basic Installation

pip install SnapQRpy

Full Installation (All Features)

pip install SnapQRpy[full]

Development Installation

pip install SnapQRpy[dev]

Quick Start

Server Side

from snapqrpy import SnapQRServer

server = SnapQRServer(port=8000)
qr_code = server.generate_qr()
qr_code.show()
server.start()

Client Side (Mobile/Desktop)

from snapqrpy import SnapQRClient

client = SnapQRClient()
client.scan_qr()
client.request_permission()
client.start_screen_share()

Command Line Interface

snapqr server --port 8000
snapqr client --scan
snapqr-gui

Advanced Usage

Custom Configuration

from snapqrpy.config import Config

config = Config(
    encryption=True,
    compression=True,
    quality='high',
    frame_rate=60,
    resolution=(1920, 1080),
    consent_timeout=30,
    session_lifetime=3600
)

server = SnapQRServer(config=config)

Security Features

from snapqrpy.security import SecurityManager

security = SecurityManager()
security.enable_2fa()
security.set_encryption('AES-256-GCM')
security.require_pin()

Event Handling

from snapqrpy.events import EventManager

events = EventManager()

@events.on('connection_established')
def on_connect(session):
    print(f"New connection: {session.id}")

@events.on('permission_granted')
def on_permission(device):
    print(f"Permission granted for: {device.name}")

API Documentation

Core Classes

• SnapQRServer - Server-side screen sharing
• SnapQRClient - Client-side connection
• QRGenerator - QR code creation and customization
• StreamManager - Video stream handling
• SecurityManager - Security and encryption
• ConsentManager - Permission handling

Network Protocols

• WebRTC for P2P connections
• WebSocket for real-time communication
• HTTP/2 for API endpoints
• gRPC for service communication

Security

SnapQRpy implements multiple security layers:

1. Encryption: AES-256-GCM, RSA-4096, ChaCha20-Poly1305
2. Authentication: OAuth 2.0, JWT, 2FA, Biometric
3. Authorization: Role-based access control (RBAC)
4. Consent: Explicit user permission required
5. Rate Limiting: DDoS protection
6. Session Security: Automatic timeout and invalidation

Performance

• Low latency: < 50ms average
• High frame rate: Up to 120 FPS
• Adaptive bitrate: Automatic quality adjustment
• Hardware acceleration: GPU encoding/decoding
• Network optimization: TCP/UDP hybrid protocol

Troubleshooting

Connection Issues

from snapqrpy.diagnostics import NetworkDiagnostics

diag = NetworkDiagnostics()
diag.test_connectivity()
diag.check_firewall()
diag.measure_latency()

Permission Errors

from snapqrpy.utils import PermissionChecker

checker = PermissionChecker()
checker.verify_screen_capture()
checker.verify_input_control()
checker.request_missing_permissions()
