SmartField vs Shadow DOM Only
A direct comparison of SmartField and Plain Shadow DOM for protecting sensitive form data.
Plain Shadow DOM
Shadow DOM alone isolates elements but Google confirms it's not a security boundary.
// With Plain Shadow DOM:
document.querySelector('input').value
// "SensitiveData123" ← readable
SmartField
SmartField uses Shadow DOM as one of 13 layers. WeakMap, AES-256-GCM, RSA-2048, event blocking, anti-screenshot, and more.
// With SmartField:
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6..." ← AES-256 encrypted
