React Native ऐप्स को secure करने में data की रक्षा करना (secure storage, encrypted transmission), secrets और tokens को सुरक्षित रूप से handle करना, JavaScript bundle को secure करना, और mobile security best practices का पालन करना शामिल है। जैसे-जैसे ऐप्स sensitive user data handle करते हैं security मायने रखती है।
Data और credential security
✓ SECURE STORAGE for sensitive data — react-native-keychain / expo-secure-store
(encrypted, keychain/keystore) — NOT AsyncStorage (which is NOT encrypted) for tokens/
credentials (a common mistake)
✓ HTTPS/TLS for all network traffic; certificate pinning for sensitive apps
✓ Don't HARDCODE secrets/API keys in the JS — the JS BUNDLE can be extracted/inspected
(anything in the app can be reverse-engineered) → keep real secrets on the SERVER
✓ Secure auth: OAuth, short-lived tokens, secure refresh; biometric auth where appropriate
