HashiCorp Certified - Vault Associate Course - Vault Data Protection

The video tutorial explains how Vault protects data using encryption keys and master keys. Vault stores data in an encrypted format on a storage back end. An encryption key is generated to encrypt data, and a master key encrypts the encryption key. The master key is not stored in traditional unseal mechanisms but is stored encrypted in auto unseal. The encryption key can be rotated easily, allowing for secure data management.
