They have multiple applications that each require a unique encryption key. The security team wants to enforce key rotation every 30 days for all keys, and also require that keys be destroyed after they are no longer used. The application team is concerned that key rotation might cause downtime because applications need to re-encrypt data. The Vault architect needs to design a key management solution. What is the best approach?
