This property can be set before calling Encrypt or Decrypt with a symmetric key to have the server include the specified data, known as additional authenticated data, when performing the cryptographic operation. If such data is provided during encryption, it must also be provided in order to successfully decrypt the data. Refer to the Google Cloud KMS documentation for more information.

This property is not available at design time.
