In Transparent Data Encryption (TDE) with a customer-managed key for Azure SQL, what does the customer-managed key (the TDE protector) actually encrypt?

TDE uses a two-tier key hierarchy for encryption at rest. The DEK performs the symmetric encryption of database files, and the TDE protector encrypts the DEK. In service-managed TDE, Microsoft controls the protector; in customer-managed (BYOK) TDE, the customer controls the protector in Key Vault or Managed HSM, enabling separation of duties and the ability to revoke access to render the database inaccessible. Switching from service-managed to customer-managed only re-encrypts the DEK, so there is no downtime or re-encryption of the database files.
