How to zip file from ExecuteStreamCommand

[#1]

I'm passing a csv flowfile to ExecuteStreamCommand. How can I zip it with password and pass it to the next processor?

I don't know how to zip file from stdin and pass it to stdout. I'm using python

This is more a Python question than a Nifi one, perhaps this will help:

import pyminizip
pyminizip.compress("myfile.txt", "myzippedfile.zip", "mypassword", compression_level)

 I would recommend you to first see if you can get the python part working, and then worry about how to call it from Nifi.
