## Security Practices

We recommend users follow these best practices when using Nuwault Core:

- Keep dependencies updated
- Do not store master passwords in plaintext
- Use HTTPS for all network communication
- Secure your runtime environment and devices
- Clear sensitive data from memory when no longer needed

## Security Features

Nuwault Core implements:

- **Deterministic generation**: Same input → same output
- **SHA-512 hashing** with multiple iterations
- **Secure random generation** for entropy-based operations
- **Input validation** to ensure consistent, expected input structure
- **Timing attack resistance** in critical comparisons

## Security Considerations

- Password strength depends on the master password you choose.
- Security also relies on your environment and application-level practices.
- Memory safety and side-channel resistance are best-effort and should be validated externally for high-security contexts.
