If you want the process to be completely automated, you would have to enforce
the controller service IDs to be identical across environments. Otherwise
deployment would need a manual intervention to reference the specific

Mitigation: Implemented Argon2 secure hashing to provide a deterministic
loggable value which does not reveal the sensitive value. Users running any
previous NiFi release should upgrade to the latest release.
Credit: This issue was discovered by Andy LoPresto and Pierre
You can use the toolkit to generate another “server/node” certificate just as
you did for the NiFi instance (do this from the same toolkit instance &
directory to ensure both are signed by the same CA) and this will generate both
the keystore and truststore JKS to use for MiNiFi.
MiNiFi’s flow definition is persisted in the config.yml file. You should
examine that file for the plaintext URL below and update it with the HTTPS URL
(protocol & port). That will indicate that it should connect over TLS.
