Hi Matt, Flink is currently enhancing its security, such as the current data transmission can be configured with SSL mode[1]. However, some problems involving configuration and web ui display do exist, and they are still displayed in plain text. I think a temporary way to do this is to keep your secret configuration in encrypted form elsewhere, such as Zookeeper or RDBMS, and then dynamically read it into the job in a UDF (in the open method).
