Burnbox – Zero-knowledge encrypted file transfer with automatic deletion

Summary: Burnbox enables secure file transfer using client-side AES-256-GCM encryption with password protection and flexible expiry from 1 hour to 30 days. It requires no accounts, retains no metadata, and deletes files immediately after download.

What it does

Burnbox encrypts files in the browser before upload, hosts them on Australian servers, and permanently deletes files after they are accessed or expired.

Who it's for

Users needing to share sensitive files like legal documents or credentials without leaving recoverable copies on servers.

Why it matters

It prevents indefinite storage and unauthorized access by eliminating server-side file retention and metadata collection.
