SmartField vs Form Encryption Libraries
A direct comparison of SmartField and JavaScript Encryption Libraries for protecting sensitive form data.
JavaScript Encryption Libraries
Libraries like CryptoJS encrypt data before submit. But the plaintext exists in memory and DOM until encryption runs.
// With JavaScript Encryption Libraries:
document.querySelector('input').value
// "SensitiveData123" ← readable
SmartField
SmartField encrypts at the keystroke level. The plaintext never exists in the DOM at any point. Not even for a millisecond.
// With SmartField:
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6..." ← AES-256 encrypted

The Bottom Line
SmartField encrypts at the keystroke level. The plaintext never exists in the DOM at any point. Not even for a millisecond. SmartField uses AES-256-GCM + RSA-2048 encryption inside a closed Shadow DOM with WeakMap isolation. 13 independent security layers. 20/20 attacks blocked.
Frequently Asked Questions
Why choose SmartField over JavaScript Encryption Libraries?+
SmartField encrypts at the keystroke level. The plaintext never exists in the DOM at any point. Not even for a millisecond.
Can I use both together?+
In most cases, yes. SmartField complements existing security measures. It adds encryption at the input level, which JavaScript Encryption Libraries does not provide.
How hard is it to switch?+
SmartField is a drop-in replacement. Change your input tag to smart-field and add the script. 2 lines of code. Your backend receives encrypted data and decrypts with one function call.
