[Q] Wifi password problem ( Rooted device )

Hi!
I encountered the same thing. The psk key seems to be encrypted. Interestingly on my note 2 with 4.2.2 the wpa_supplicant.conf is unencrypted. Either this is a "feature" of 4.3 or, what I tend to think, it's samsung specific. The whole thing idea behind Knox is to "increase" security for company usage. So an unencrypted psk might seem to be a bad idea for samsung. I'm gonna flash my note 2 with a modified 4.3 original ROM and gonna take a look into the conf then if it is also encrypted then.

Did you notice the "ss_enc=1" line? Maybe this toggles the encryption. There seem to exist a system function with that name to encrypt addresses with a specified key. Gonna try to switch it off with "ss_enc=0" and see what happens.
Can anyone share some deeper insights in this issue?

Ok, no use toggling 0. It was right reactivated after a reboot. Would have been to easy otherwise. Maybe thw behaviour is toggled somewhere in another conf, but my guess it is "hardcoded" somewhere. What a pity.

I don't see how not viewing stored Wi-Fi passwords is an issue. You should know the password already if it's your Wi-Fi. If you forgot it, you can access it via the Wi-Fi router, or reset it. If your companies tech support input it for you, they can input it again. Can you give me some insight as to why you need to retrieve already stored passwords?

There are quite some reasons:
- Not keeping a second list for the passwords of all the networks stored in your device. Am I the only one who has 20+ networks stored?
- Many ppl think there is no way of retrieving the psk from the device once stored, like many years ago in Windows XP
- Because it should pe possible; no other linux distribution of my knowledge does it; so why is it done and how is it done?
- security by obscurity is a bad thing.

In my opinion "Because I have 20+" isn't a valid reason to retrieve wifi passwords. I still wait for a valid one.

You can obtain stored wifi passwords very easily from a rooted device! The only thing is you need to decode them. So even after you retrieve them it's still a P.I.A.! It would be much easier to create a list of 20+ ssid's and passwords and email them to yourself. Or keep an excel file of them on dropbox. It's a pain because once we enter our password into our phone it's encrypted. Most people use WPA-PSK encryption. I don't have a secret decoder ring for this. Do you? If so tell me what the password to my wifi with an ssid of Not_Yours_5G is. My wifi password will tell you how to retrieve wifi passwords from a rooted note 3. The information I pulled from my note 3 is below.
