✅ Security Features Implemented:
- Web Crypto API - Client-side encryption
- Key Management - Secure key generation
- Data Sanitization - Input cleaning
- Secure Cookies - Proper configuration
- Session Management - Secure sessions
// ✅ SECURE: Web Crypto API encryption

const dataBuffer = encoder.encode(JSON.stringify(data));
const encryptedData = await crypto.subtle.encrypt(
{ name: 'AES-GCM', iv: crypto.getRandomValues(new Uint8Array(12)) },
key,
dataBuffer
);
return encryptedData;
}
// ✅ SECURE: Key generation
async function generateSecureKey() {
return await crypto.subtle.generateKey(
{ name: 'AES-GCM', length: 256 },
true,
['encrypt', 'decrypt']
);
