The binary secret data that was retrieved or that should be sent.
property SecretData: TBytes read get_SecretData write set_SecretData;
Either this property or the SecretString property is populated with secret data after calling GetSecret, depending on whether the secret data is binary or textual, so long as SetOutputStream and LocalFile are not set.
This property and SecretString are mutually exclusive; setting one will clear the other.
This property is not available at design time.
