ConfiMsg
End-to-end encrypted. Read once. Gone forever.

Send Encrypted One-Time Messages

ConfiMsg lets you send secret messages that self-destruct after being read once. Your message is encrypted directly in your browser using AES-256-GCM military-grade encryption — the server never sees the content. Perfect for sharing passwords, credentials, API keys, or any sensitive information.

🔒 Zero-knowledge The decryption key never leaves your browser. Even we cannot read your messages.
💥 Read once The message is permanently deleted from our servers the moment it's opened.
🚫 No account No registration, no login, no tracking.
📎 Attachments Attach images and documents — encrypted the same way as your message.

How it works

  1. Type your secret message and optionally attach a file.
  2. Click "Encrypt & Create secure link" — encryption happens in your browser.
  3. Share the link via any messenger, email, or SMS.
  4. The recipient opens the link once — the message is then permanently deleted.
