Kistrl Share

Share a password once. Then it’s gone.

Paste a password, an API key or a private note. Kistrl encrypts it in your browser and gives you a link that opens once.

How it works

Kistrl never sees your secret

Your browser encrypts it before anything is sent. The key travels inside the link, in a part browsers keep to themselves.

  1. You paste a secret

    Your browser makes a random key and encrypts the secret with AES-256-GCM.

  2. Kistrl stores a locked box

    Only the ciphertext reaches us. The key stays after the # in the link, which browsers don’t send.

  3. They open it once

    The recipient clicks Reveal, their browser decrypts it, and we delete the ciphertext. Link previews in Slack or Teams don’t use up a view.
