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.---
