Secure data encryption is critical for protecting sensitive information. Here are key guidelines to follow:
1. Use Strong Algorithms
- Prefer AES-256 (Advanced Encryption Standard) for symmetric encryption.
- For asymmetric encryption, use RSA-2048 or ECC (Elliptic Curve Cryptography).
2. Manage Keys Securely
- Store private keys in hardware security modules (HSMs) or key management services (KMS).
- Avoid hardcoding keys in source code; use environment variables or secure vaults.
3. Keep Certificates Updated
- Regularly renew SSL/TLS certificates before expiration.
- Use automated certificate management tools like Let's Encrypt.
4. Implement Secure Protocols
- Always use HTTPS (HTTP Secure) for web communications.
- Enable TLS 1.3 or higher to ensure robust encryption standards.
5. Protect Data in Transit & At Rest
- Encrypt data both during transmission (e.g., TLS) and storage (e.g., AES).
- Use end-to-end encryption for sensitive user data.
