Look inside

Help ShareSafe’s customers share with confidence. You’re a developer for a company that provides online file-sharing-as-a service. Its users can upload and share personal documents, photos, and videos onto ShareSafe’s website using APIs. Your task is to add security to ShareSafe’s file-transfer REST API service. You’ll implement a user-authentication layer using JSON Web Tokens (JWTs), provide authorization for shareable URLs by establishing the relationship between users and files, and leverage macaroons (cryptographic cookies) to provide a secure way for users to share files.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.
