Share a secret, once

Paste a password or pick a file and get a link that works exactly once. The secret is encrypted in your browser before it is uploaded, and the key travels in the part of the link after the #, which browsers never send to a server. SuperShare stores ciphertext and nothing else — not your text, not your filename, not your passphrase.

How it works

1. You paste text or choose a file, and pick how long the link should live.
2. Your browser encrypts it and uploads only the ciphertext.
3. The first person to press Reveal gets it, and the server deletes it.
