Key rotation is systematic refreshing of encryption keys (API keys, TLS certs, signing keys) to limit exposure if leaked. Mastery takes 6-8 weeks. Senior practitioners earn 35-45% premium because they prevent data breaches. The 2% who design zero-downtime rotation for distributed systems (100+ services, 1000+ keys) are highly sought after in security/compliance roles.
Key rotation is the practice of systematically replacing cryptographic keys with new ones on a scheduled basis, or in response to compromise. A key (API key, encryption key, TLS cert, database password) has a lifecycle: creation, active use, rotation, retirement. Each rotation creates a new key, starts using it, and eventually disables the old key. The process must be automated to avoid human error. Tools (Vault, AWS KMS, cert-manager) manage the entire lifecycle, generation, distribution, rotation, audit logging, and emergency procedures.
