## 🔒 SECURITY NOTES
|
|
|
|
### Current Implementation
|
|
- ✅ Client-side validation
|
|
- ✅ Database constraint (UNIQUE NPM)
|
|
- ✅ Exception handling
|
|
- ❌ No password hashing (plain text)
|
|
- ❌ No encryption
|
|
|
|
### For Production Use
|
|
1. **Hash passwords** sebelum menyimpan
|
|
```kotlin
|
|
fun hashPassword(password: String): String {
|
|
val md = MessageDigest.getInstance("SHA-256")
|
|
return Base64.encodeToString(md.digest(password.toByteArray()), Base64.NO_WRAP)
|
|
}
|
|
```
|
|
|
|
2. **Add HTTPS** untuk API calls
|
|
|
|
3. **Implement JWT** untuk session management
|
|
|
|
4. **Add rate limiting** untuk login attempts
|
