    Is the `SecureRandom` initialized externally for a reason? Is this just to 
make testing easier?

> In order to facilitate secure setup of NiFi, it would be useful to have a 
> command line utility capable of generating the required keystores, 
> truststore, and relevant configuration files.
> It should be able to generate keystores for each NiFi node, a truststore that 
> they all use, and relevant passwords and configuration files for using the 
> keystores and truststore.
> Additionally, in order to support distributed deployment, a web based 
> certificate authority with corresponding client will allow for each NiFi 
> instance to generate its own keypair and then request signing by the CA.
