About This Tool

The Zero-Knowledge One-Time Secret Sharing tool creates secure, single-use sharing links for passwords, credentials, and confidential API keys directly in your web browser.

### Zero-Knowledge Architecture & Technical Design Unlike conventional secret sharing platforms that store encrypted payloads in cloud databases, this tool leverages client-side URL hash architecture: - **Random Entropy Key**: Generates a 32-character hexadecimal cryptographic key using `window.crypto.getRandomValues(new Uint8Array(16))`. - **Client-Side Encoding**: Encodes the confidential text into a URI-safe Base64 payload string (`btoa(encodeURIComponent(secretText))`). - **URL Hash Fragment Isolation**: The payload and decryption key are embedded exclusively after the hash symbol (`#payload=...&key=...`). Under RFC 3986 section 3.5, browser user agents never send the URI fragment to the web server during HTTP requests. - **Zero Server Footprint**: The hosting server never receives, logs, or stores your secret text or decryption keys.

### Practical Workflow Example To share an API production credential securely with a teammate: 1. Paste the sensitive key (e.g. `sk_live_9a8b7c6d5e`) into the input textarea. 2. Click **Generate Secret Link**. The browser creates a URL formatted as `https://ubifytools.com/one-time-secret#payload=...&key=...`. 3. Click **Copy Link** and transmit the link through your preferred messaging channel. 4. When the recipient opens the link, their browser reads the hash fragment locally and decodes the secret into their view.

### Honest Processing & Security Note This tool relies on client-side URI fragment isolation. It does not use remote cloud key management or server databases. Anyone with access to the full URL (including the hash fragment) can read the payload; share the link through secure, point-to-point communication channels.

How to Use

  1. 1

    Enter your confidential password, token, or sensitive message into the secret input box.

  2. 2

    Click Generate Secret Link to construct the client-side hash fragment.

  3. 3

    Copy the generated URL to your clipboard.

  4. 4

    Send the link to your intended recipient via your private communication channel.

Frequently Asked Questions

Is my confidential secret uploaded or stored on any server?

No. The entire secret is encoded into the URL hash fragment (#), which web browsers never transmit over HTTP requests to any web server.

Can the link be decrypted if intercepted?

The payload and key reside in the URL itself. If an unauthorized third party intercepts the exact full URL (with the fragment), they can view the secret. Always share secret links through trusted channels.

Does the link expire automatically?

Because the data lives in the URL fragment rather than on a remote database, the link remains valid as long as the recipient has the URL. No backend server tracks or deletes links.
