🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
How to use
- Enter the confidential content you want to share securely.
- Check the password option to protect the payload using a custom AES-255 decryption key.
- Click 'Generate Link' and share the complete URL with your recipient.
FAQ
- How is it possible that no server keeps track of my secrets?
- The data is appended to the URL fragment (#). According to HTTP specifications, the hash fragment is never sent to the web host. Therefore, your secret never touches the server.
- Can recipients decrypt payloads on mobile devices?
- Yes. Modern mobile web browsers fully support native Web Crypto APIs and DecompressionStream to unpack and decrypt payloads natively.
