This app showcases real-world Authentication and Authorization techniques with NestJS from access to refresh tokens, and everything in between (JWT authentication, role-based and claims-baes access control, policy-based authorization, API keys, server-side sessions, 2FA authentication, and more).

A secure policy-driven file sharing system that uses AES-256-GCM and RSA-4096 encryption with PIN, expiry, revocation, geofencing, and audit logging for controlled document access.

This project demonstrates the deployment process for the Microsoft Global Secure Access (GSA) Client, a core component of Microsoft's Secure Service Edge (SSE) architecture.
