Hashcat + wlangenpmkocl how to convert back to plaintext ?

[pr0ph3t]

Some IoT devices transmit the PSK in the clear.
If a user made a type (PSK instead ESSID), the device transmit the PSK in the clear.
A misconfigured device can cause that the PSK is transmitted in the clear.
-E will store them to a list
-I will store received identities (that include IMEIs) to a list
-U will store received usernames to a list

All this lists can be used to create new wordlists.

BTW:
I decided to make my test tool (hcxpmktool) public.
It provide various tests on a single hash line (-m 22000 WPA 01 and WPA 02) in combination with ESSIDs, PSKs and PMKs. It will help you to understand better how things (PBKDF2) relate. Nearly every PBKDF2 combination (used in WPA) is possible:
ESSID + PSK
ESSID + PMK
ESSID + PSK + 22000 hash line
PSK + 22000 hash line
PMK + 22000 hash line

Some examples (22000 example hash taken from here: https://hashcat.net/wiki/doku.php?id=example_hashes)

Code:

$ hcxpmktool -i WPA*01*4d4fe7aac3a2cecab195321ceb99a7d0*fc690c158264*f4747f87f9f4*686173686361742d6573736964*** -p 'hashcat!'

Thank you VERY much just updated the repo on my system. git remote update,  git pull, git fetch, make, make install for the noobs like myself. (Correct me if you have a better method heh)

Revising everything now and going to start testing
