WebAuthn Rust - Backend for Polling Application

Overview

webauthn_rust is a Rust-based backend application that provides secure authentication using WebAuthn (passkeys) and serves as the backend for a polling system. Built with actix-web, this backend handles authentication, session management, and polling operations efficiently.

Features

• Passkey Authentication: Secure WebAuthn-based authentication without passwords.
• Polling API: Endpoints for creating, managing, voting on, resetting, and closing polls.
• WebSockets Support: Enables real-time interactions.
• CORS Enabled: Allows communication with frontend clients.
• Session Management: Uses actix-session for handling user sessions.

Technologies Used

• Rust (Backend language)
• Actix-web (Web framework)
• WebAuthn-rs (Passkey authentication)
• Actix-session (Session management)
• Actix-cors (CORS handling)
• WebSockets (For real-time updates)
• PostgreSQL (For poll data storage, optional integration)

API Endpoints

Authentication

• POST /register/start/{username} - Begin user registration.
• POST /register/finish - Complete user registration.
• POST /login/start/{username} - Start authentication.
• POST /login/finish - Complete authentication.

Poll Management

• POST /poll/new - Create a new poll.
• POST /polls - Fetch all polls.
• POST /polls/{poll_id}/vote - Vote on a poll.
• GET /polls/{poll_id} - Get poll details.
• POST /polls/manage - Manage user polls.
• POST /polls/{poll_id}/close - Close a poll.
• POST /polls/{poll_id}/reset - Reset poll votes.

WebSockets

• GET /ws - Establish a WebSocket connection.

Roadmap & Future Enhancements

• Implement persistent session storage (e.g., Redis).
• Enhance WebSocket support for real-time poll updates.
• Add role-based access control (RBAC) for better user management.
• Improve database integration for scalable polling storage.
