Cloud Kms
All CryptoKeys created with this EkmConnection use EKM-side key management operations initiated from Cloud KMS. This means that: * When a CryptoKeyVersion associated with this EkmConnection is created, the EKM automatically generates new key material and a new key path. The caller cannot supply the key path of pre-existing external key material. * Destruction of external key material associated with this EkmConnection can be requested by calling DestroyCryptoKeyVersion. * Automatic rotation of key material is supported.
