### Server-Side Encryption with a KMS

SSE-S3 allows an S3 client to en/decrypt an object at the MinIO server using a KMS. The MinIO
server only assumes that the KMS provides two services:

- `GenerateKey`: Takes a key ID and generates a new data key from a master key referenced by the key ID. It returns the new data key in two different forms: The plain data key and the data key encrypted using the master key.

		KeyID: keyID,
	}

	// 1. Generate a new key using the KMS.

	if err != nil {
		response.EncryptionErr = err.Error()
		resp, err := json.Marshal(response)
