RocketShare – Zero-knowledge encrypted file sharing with client-side encryption

Summary: RocketShare encrypts files in the browser using AES-256-GCM, storing only encrypted data on servers while the decryption key remains in the URL fragment. It supports link expiry, optional password protection, download limits, resumable chunked uploads, and streaming downloads across devices.

What it does

Files are encrypted locally before upload, with the key embedded in the URL fragment so servers never access it. Users can set link expiration from 1 to 90 days, add passwords, limit downloads, and send links via email. Uploads can resume within 24 hours and downloads stream decrypt large files or ZIP archives.

Who it's for

Users needing private file sharing without trusting servers with encryption keys, including those requiring temporary, controlled access links.

Why it matters

It prevents servers from accessing file contents by keeping encryption keys client-side, enhancing privacy and security for shared files.
