Sensitive Data Types

Secure Password Input

Passwords entered in standard inputs are visible to any JavaScript on the page. SmartField encrypts every character with AES-256-GCM. The DOM never contains the plaintext password.

Secure Credit Card Input

Credit card numbers in standard inputs are targets for Magecart, JavaScript skimmers, and session replay tools. SmartField encrypts card data at the keystroke level with built-in Luhn validation.

Secure CVV Input

CVV codes are the most sensitive payment field. SmartField encrypts 3-4 digit CVV codes with AES-256-GCM. The code never appears in the DOM, browser autosave, or screen recordings.

Secure Bank Account Input

Bank account and routing numbers entered in web forms are vulnerable to XSS, extensions, and analytics tools. SmartField encrypts them before they reach the DOM.

Secure SSN Input

SSNs are the most targeted personal identifier. SmartField encrypts 9-digit SSNs with AES-256-GCM, enforces format validation, and blocks all extraction attempts.

Secure Medical Record Input

Patient data entered in web forms is protected by HIPAA but exposed in the browser DOM. SmartField encrypts diagnoses, prescriptions, and lab results at the keystroke level.

Secure Seed Phrase Input

A seed phrase in a standard input can be stolen by one browser extension. SmartField encrypts seed phrases character by character. The browser never sees the real words.

Secure Private Key Input

Crypto private keys entered in web forms are the highest-value target. SmartField encrypts them with AES-256-GCM + RSA-2048. Zero exposure to JavaScript, clipboard, or screen capture.

Secure Tax ID Input

Tax identification numbers are used for identity theft. SmartField encrypts tax IDs at the keystroke level, invisible to analytics, extensions, and injected scripts.

Secure Passport Number Input

Passport numbers entered on immigration and travel websites are exposed to every script on the page. SmartField encrypts them with military-grade AES-256-GCM encryption.
