Github user thenatog commented on the issue: https://github.com/apache/nifi/pull/2761 Looks fine to me after looking at https://issues.apache.org/jira/browse/NIFI-4942, executed encrypting a properties file which worked and attempted to use the -z param which no longer works. Had a look through the code changes/remaining code and didn't see anything related to the hashing being left behind.
