How does the encrypted HTML file work?

The image is encrypted with AES-256-GCM and embedded in a self-contained HTML file. Opening it in any browser shows a password prompt — the correct password decrypts and displays the image.

Does this require an internet connection to open?

No — the HTML file is completely self-contained with all decryption code inline. It works offline in any modern browser.

Is the encryption strong?

Yes — AES-256-GCM with PBKDF2 key derivation (100,000 iterations, SHA-256). This is the same encryption used in banking and government systems.

What if someone enters the wrong password?

AES-GCM's authentication tag fails with an incorrect password, showing an "Incorrect password" error. There is no brute-force limit on the HTML file itself, so use a strong password.
