I would like a method to see a cleartext password decrypted from wpa_supplicant.conf on my Samsung Galaxy S4 with Android 5.0.1 The problem is that the passwords, or psk's, are encrypted and even if my device is rooted and I can access the file I can't see the passwords decrypted. From what I have learned reading on the web Samsung or Android changed so that all WIFI passwords are encrypted from an earlier version for security reasons.
The reason I need to see the password in cleartext is that I am working as IT manager for a company and the router can in some cases be hacked using an android phone. I would like to investigate further and need the option to actually see if the correct password was retrieved or if it is some default router pin or similar.
A typical psk would look like
And I have yet not been able to figure out what encryption method is used or how to unhash it. I would appreciate any help!
