Explain the importance of proper key management in cryptographic systems.

Proper key management is critical for cryptographic security as it encompasses the entire lifecycle of cryptographic keys including generation, distribution, storage, rotation, and destruction. Weak key management can compromise even the strongest encryption algorithms. Key considerations include using cryptographically secure random number generation, implementing secure key storage (HSMs), regular key rotation, proper access controls, and secure key distribution mechanisms. Effective key management ensures confidentiality, integrity, and availability of encrypted data throughout its lifecycle.
