One-Time Secret
Share a password or note through a link that destroys itself after a single view. The text is encrypted in your browser and the key lives in the URL fragment, which browsers never send to a server.
Why we cannot read it: your browser generates an AES-256 key, encrypts the text, and puts the key in the part of the URL after the
#. Browsers never send that part to a server. We store ciphertext and an IV, and delete both the moment the link is opened.
