Manual
EKM-side key management operations on CryptoKeys created with this EkmConnection must be initiated from the EKM directly and cannot be performed from Cloud KMS. This means that: * When creating a CryptoKeyVersion associated with this EkmConnection, the caller must supply the key path of pre-existing external key material that will be linked to the CryptoKeyVersion. * Destruction of external key material cannot be requested via the Cloud KMS API and must be performed directly in the EKM. * Automatic rotation of key material is not supported.
