💡 How it works

  1. Set a Password:
    Use the generator to create a strong, random password. Remember it or send it to your recipient via a secure channel (like Signal).
  2. Choose Payload:
    Enter a secret message (Option A) or select any file from your device (Option B).
  3. Create HTML:
    Click the button. Your data will be encrypted inside your browser and packed into a standard .html file.
  4. Share Securely:
    Send the generated HTML file to anyone. They only need a web browser and the password to unlock it.
🛡️ Privacy First & Zero-Knowledge:
This tool runs 100% locally in your web browser.

Why is this important?
Unlike cloud-based services, your plain text, files, and passwords never leave your device. There is no server that could be hacked, no database that could leak your files, and no middleman intercepting your secrets. We couldn't read your data even if we wanted to. You retain complete control over your privacy.

Powered by military-grade AES-256-GCM encryption and the memory-hard Argon2id algorithm.
