Protect Password Fields in Banking from XSS
In banking, password is one of the most targeted data types. Standard HTML inputs expose it to xss attacks. SmartField encrypts it at the keystroke level.
The Risk
Password entered in a standard form is immediately accessible:
// XSS attack:
document.querySelector('input').value
// "Password data here" ← stolen
The Fix
<smart-field type="password" encrypt-key="/api/sf-key"
placeholder="password"></smart-field>
Now the same attack returns AES-256-GCM encrypted data. The password never exists as plaintext in the browser.
What the Attacker Gets
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6IkNxT3..." ← 600+ chars of encrypted gibberish
Useless without your server's RSA-2048 private key.
Compliance
SmartField uses NIST-approved algorithms: AES-256-GCM (SP 800-38D) and RSA-2048 (SP 800-56B). Compatible with PCI-DSS, HIPAA, GDPR, SOX, and FISMA requirements.
Frequently Asked Questions
How does SmartField protect password in banking?+
SmartField encrypts password at the keystroke level using AES-256-GCM. The data never exists as plaintext in the browser DOM. XSS Protection is achieved through 13 independent security layers including closed Shadow DOM and WeakMap isolation.
Can xss attacks steal password?+
Not with SmartField. The .value property returns encrypted payloads only. The real password is stored in a WeakMap inside a closed Shadow DOM, invisible to any JavaScript including xss attacks.
How do I implement this?+
Replace your standard input with smart-field. 2 lines of HTML. Install the server SDK (Node.js, Python, Java, Go, PHP, or Ruby) to decrypt on your backend.
