Create a one-time secret link
Generate an encrypted one-time link for messages, passwords or files — usable exactly once and deleted afterwards. The key stays in the link fragment; the server never sees it.
What zero-knowledge gives you
- Works exactly once (burn-after-read)
- Optional expiry from 1 hour to 7 days
- Optional password and recipient approval
- Zero-knowledge in-browser encryption
When a one-time link is the right tool
A one-time link fits the situations where a message should exist just long enough to be received: an access credential for a new colleague, a document for a single review, a recovery code, a contract draft that should not sit in an inbox for years.
The mechanism is deliberately simple. One retrieval, then the encrypted payload is gone. There is no account to manage, no shared vault to maintain, and no expectation that both sides have installed the same software. The recipient needs a browser and the link, nothing else.
What it does not do is track who opened it or prove identity. If that matters, add a password so the link alone is insufficient, or switch on recipient approval so you have to release the content explicitly before it can be decrypted.
Frequently asked questions
What is a one-time link?
A link that works exactly once. After the first retrieval the encrypted content is deleted server-side; the key lives in the URL fragment and never reaches the server.
Do I need an account?
No. Add your content, get the one-time link and share it.
