BurnLink – Secure, ephemeral encrypted file sharing

Summary: BurnLink enables one-time sharing of sensitive files with end-to-end encryption and links that self-destruct after a single access. It requires no accounts or permanent storage, ensuring zero-knowledge security by encrypting files entirely in the browser and never exposing keys to the server.

What it does

BurnLink encrypts files in the browser using AES-256-GCM and PBKDF2, then generates a one-time link containing the decryption key in the URL fragment. The recipient can open the link once, after which the file is permanently deleted with no trace or recovery.

Who it's for

It is designed for developers, operations teams, freelancers, and anyone needing to share sensitive files securely without using accounts or secrets managers.

Why it matters

BurnLink eliminates the risks of sharing credentials or confidential files via insecure channels by providing true zero-knowledge, one-time access without storing metadata or requiring trust in the service provider.
