Share information securely with client-side AES encryption.

How it works

1. You write a message and click Share.
2. A random 5-character secret is generated locally in your browser.
3. The message is encrypted with AES using that secret — before leaving your device.
4. Only the encrypted text is sent to the backend. The secret is never sent to the server.
5. You get a shareable link containing the id and secret.
6. When someone opens the link, the encrypted text is fetched and decrypted locally in their browser.
