SecureShare
by Cyberace
Protocol · Zero-Knowledge

Share passwords and text without a trace.

Paste a password or a short text, generate a one-time link, and share it. Encrypted in your browser, it self-destructs after being read.

Why SecureShare

Encrypted in your browser

AES-GCM 256-bit via WebCrypto. Your secret is never sent in cleartext.

Zero-knowledge

We only store ciphertext. The key travels in the URL fragment — invisible to the server.

No accounts, no tracking

No IP logging, no login required, no user profiling.

Zero-Knowledge

How it works

SecureShare turns a secret into a one-time link using encryption that happens inside your browser. The server only stores the encrypted payload; the key never leaves your device.

  1. 01 /

    Paste your secret

    Type or paste the password, note, or text you need to share. Nothing is sent until you click generate.

  2. 02 /

    Encrypt in browser

    Your browser creates a 256-bit AES key and a random IV, then encrypts the secret with AES-GCM before any data leaves your device.

  3. 03 /

    Store ciphertext only

    Only the encrypted text and expiry reach our server. We cannot decrypt it because we never receive the key.

  4. 04 /

    Share the link

    The key is appended after the # in the link. The recipient's browser uses it to decrypt locally, and the secret self-destructs after use.

Why the key lives in the URL fragment

Browsers never send the part after # to the server. That means the key stays on the client, so even if someone intercepted the request, they would only see unreadable ciphertext.
