> Add support for NiFi Registry to the encrypt-config tool in NiFi Toolkit
> ------------------------------------------------------------------------
>
> Key: NIFI-4708
> URL: https://issues.apache.org/jira/browse/NIFI-4708
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Kevin Doran
> Assignee: Kevin Doran
> Fix For: 1.5.0
>
>
> NiFi Registry now supports loading encrypted config files (e.g.,
> nifi-registry.properties, authorizers.xml, login-identity-providers.xml).
> These files are very difficult to encrypt by hand, and is not recommended.
> Because NiFi Registry utilizes the same encryption algorithms supported by
> NiFi, the easiest way to build a tool for encrypting NiFi Registry config
> properties is to extend the the encrypt-config tool in NiFi Toolkit to
> support NiFi Registry as well.
