Github user YolandaMDavis commented on the issue: https://github.com/apache/nifi/pull/2628 Spoke with @alopresto offline. He highlighted that is it important to maintain control of location of secure-hash.key file in order to prevent calling application from piping into a file that is controlled externally.
