Password protect a static HTML page.

StatiCrypt uses AES-256 to encrypt your HTML file with your passphrase and return a static page including a password prompt and the javascript decryption logic that you can safely upload anywhere (see what the page looks like).

This means you can password protect the content of your public static HTML file, without any back-end - serving it over Netlify, GitHub pages, etc. (see the detail of how it works).
