  • Recommendation: Hybrid approach during transition period

Best Practices

  1. Key Management: Use hardware security modules for key storage
  2. Parameter Selection: Choose appropriate parameter set for security requirements
  3. Hybrid Deployment: Maintain ed25519 compatibility during migration
  4. Regular Updates: Monitor NIST standards for algorithm updates
