BurnLink lets you share a password, API key, or sensitive note through a one-time link. Everything is encrypted in your browser before it's sent — the server never sees your secret, and the link destroys itself the moment it's read. Free, no signup.

Hey Product Hunt 👋 I built BurnLink after one too many times seeing passwords and API keys just sitting in email threads forever. The idea is simple: you paste a secret, get a link, and once that link is opened, the content is gone for good — no trace, no copy left anywhere. Some things I focused on: - AES-256 encryption happens entirely in your browser before anything is sent - In "link" mode, the decryption key lives only in the URL fragment, which never even reaches the server - If you protect it with a password instead, a wrong guess never destroys the secret — you can retry until it expires - No account, no tracking beyond what's needed to run the service It's a solo project, built and shipped on nights/weekends. Would love your feedback — especially if you spot an edge case I missed on the security side.

Shared a test API key with myself across two browsers and it actually self-destructed after the first view. The whole flow took about ten seconds and I never had to sign up, which is exactly what I wanted for something this small.
