I setup successfully a secured Nifi server (containing one node) using tls-toolkit in standalone mode.
I'm asking the difference between tls-toolkit in standalone and client/server modes and when using each mode.
The TLS Toolkit (and its different modes) is covered in the NiFi Sys Administration Guide, specifically:
There is also a helpful HCC article here:
which makes the distinction:
Additionally, there is help available for each mode if you want to see the available commands. For example:
./bin/tls-toolkit.sh standalone -help
Thanks @Andrew Lim
Standalone and client, both generate the certificate authority, keystores, truststores. Sorry I don't see the difference.
