File sharing, with access in mind.
An educational file-sharing application with two-factor authentication, isolated storage and audit logs.
01 / The challenge
The question behind the system.
Design a usable file-sharing flow while introducing authentication, storage boundaries and activity records.
This Flask application explores the security concerns around file storage and sharing: who can sign in, what they can access and how activity is recorded. SQLite stores application data, while per-user directories separate uploaded files.
02 / The approach
From architecture to implementation.
- 01
Use Argon2 password hashing and TOTP two-factor authentication.
- 02
Separate user storage, expose folder sharing and check upload size and type.
- 03
Record sensitive actions and apply rate limits to relevant endpoints.
03 / Outcomes
What the work shows.
- The application combines account creation, two-factor setup, folder management, sharing and activity views.
04 / Scope & next steps
Where the work stands.
- This is an educational implementation, not a security-audited storage service. Granular permissions and upload malware scanning remain on its roadmap.
