End-to-End Encrypted File Sharing
Encrypt files in the browser, share expiring links, log every access
3-4 weeks build
Overview
Files are encrypted with AES-GCM in the browser before upload, and the decryption key travels only in the link fragment, which the server never sees. Recipients decrypt locally after opening the link. Links can expire by time or download count, and the owner sees an access log of when and from where each file was fetched.
What makes it stand up
- 01Client-side AES-GCM encryption; the server stores ciphertext only
- 02Decryption key kept in the URL fragment, out of server logs
- 03Links that expire by time, by download count or on revocation
- 04Access log of timestamp and coarse location per download
- 05Optional password wrap for an extra factor on the link
Module breakdown
- 01
Client crypto
Encrypts and decrypts files in the browser via WebCrypto.
- 02
Upload service
Stores encrypted blobs and issues shareable link tokens.
- 03
Link policy
Enforces expiry, download caps and manual revocation.
- 04
Access log
Records each fetch with time and coarse geolocation.
- 05
Recovery
Handles wrong keys and expired links with clear errors.
After this, you will be able to
- Explain why the key in the fragment stays hidden from the server
- Defend the link-expiry and revocation model against misuse
- Demo a full encrypt, share, download and revoke cycle
