Abstract
A key protection framework for a platform includes a key protection engine for interfacing between an external key management system (KMS) and an external encryption service. A customer of the platform can select an existing external KMS and external encryption service to use with the framework. The key protection engine can onboard the external KMS with the platform by obtaining a configuration for the external KMS. Information extracted from the configuration can be used to establish a connection between the key protection engine and the external KMS, via which the key protection engine can interface with the external KMS to initiate rotation of a cryptographic key at the external KMS. Responsive to detection of a new version of a master key, the key protection engine can transmit a request to the external KMS to re-encrypt the cryptographic key with the new version of the master key.
