How to View Saved Wi-Fi Passwords on Chromebook

A few days back, I visited a coffee
shop and like always I asked the
barista for the Wi-Fi password. But
the reaction I got was something I
never expected. Now, usually, I get
the Wi-Fi password on my bill for
prepaid orders which I put in my
Chromebook to get started. Hot
coffee with some writing to do, that’s
how the next few hours go.

That day, the barista came over to
my table, asked me to look in a
different direction (that’s what
pissed me off) while he typed in the
password. I was like, “ what did he
think I would do with his Wi-Fi
password? Sell it on eBay may be. If
he is so insecure, he should change it
on a daily basis rather than asking
the customers to look in a different
direction.”
Anyways, I quickly finished my
coffee and before leaving, I went
over to the guy and handed over the
bill to him with the Wi-Fi password
he was so possessive about. He was
surprised but I loved the look on his
face.
It’s quite tricky to find the Wi-Fi
password of the connected network
on a Chromebook, but as you can
see, it can be useful at times. Let’s
have a look how I did it.
crosh> shell
chronos@localhost / $ sudo su
localhost / # cd /home/root/
localhost root # ls
Here you will get the list of a folder
with a long string. Just type in CD
and a tab and then press enter. You
will be taken to the directory. For
example
localhost root # cd
6ac138e6f72d5b28ee8d9a344ada72f
localhost
6ac138e6f72d5b28ee8d9a344ada72f
#
Finally, type the command “more
shill/shill.profile” and press enter.
You will see a line of texts which will
have the Wi-Fi information of
networks you have connected to till
date.
Find the Wi-Fi SSID you wish to get
the password for and spot the line
which says “Passphrase=rot47:”
followed by some random text. Well,
this is the Wi-Fi password but it’s
encrypted. To decrypt type in the
command echo <code> | tr ‘!-~’ ‘P-
~!-O’. Replace the <code> wish the
code that you get as the passphrase.
That’s all, you will have the Wi-Fi
password on the screen.
