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.
