One-Time Secret Share Link
Generate end-to-end encrypted, zero-knowledge, burn-on-read links to share sensitive passwords and API keys securely.
URL Hash Security
The part of the URL after the # is processed locally by the browser. Web servers never receive the hash parameter in HTTP requests. Thus, the decryption key stays entirely private to the participants.
Auto-Expiration
Secrets are stored in-memory or files. They are automatically burned upon first request. For additional security, unused secrets are cleaned up from server storage, ensuring they do not persist indefinitely.
Complete Guide: How to Use the One-Time Secret Sharing Link
Sharing sensitive passwords, security tokens, or customer files via email, Slack, or chat leaves permanent logs in communications history. Our free online One-Time Secret Sharing tool creates end-to-end encrypted link nodes that auto-delete immediately upon read, leaving zero logs.
Step-by-Step Instructions
- Type or paste the password, API token, or secret message into the input text box.
- Click the 'Generate One-Time Link' button.
- The browser encrypts the secret locally using AES-256 and transmits only the encrypted cipher to the server.
- Copy the generated link (which contains the decryption key in the # hash segment).
- Share the link with your recipient. Once they open it, the secret is permanently deleted from the database.
Key Features & Benefits
- Zero-Knowledge Architecture: The decryption key is part of the URL hash fragment (#), which browsers never send to the server. We cannot decrypt your secret.
- Burn-on-Read: The database erases the encrypted secret the microsecond it is fetched by the recipient.
- AES-256 Encryption: Industry-standard security ensures that even if database records are intercepted, they cannot be read without the key.
- Client-Side Performance: Encryption and key generation are processed instantly in your browser context.
