I have spent way too much time trying to figure out how to save myself time obscuring my personal info from my config files. So I'm going to share what I found and then someone will say "why didn't you just do this really easy thing?"
I'm not an expert at this I just kept searching for examples and trying them until I found something that worked for me.
If you know a better way, please share.
If someone has written a script that automates the process I would love to hear about it.
Because going through line by line SUCKS!
In Notepad++, in find and replace, tic the box that says "Regular expression"
If you put in the find window [a-fA-F0-9]{2}(:[a-fA-F0-9]{2}){5} it will find all your mac addresses and you can replace it with whatever you want '#:#:#:#:#:#'
\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3} will find all IP addresses
option name (.+) will find dhcp names and you can replace it with option name '****' or whatever your heart desire.
Same for option key (.+) to hide passwords.
