Say I type in my wifi password and press "Remember" or something. It should store it, either as a hash or plain text, in a file somewhere.

  1. Where is that file?
  2. Is it stored as a hash or plain text?

  • If a device is storing a password, without ever needing further input from you, it's stored in plain text. It may be obfuscated, but it won't be worth much in the terms of real security. How could a hashed wifi password possibly be useful for a client node?

If you are using normal settings on Raspbian it will be in /etc/wpa_supplicant/wpa_supplicant.conf. It is stored in plain text, but only root can see it - you will need sudo to access the file.

See How do I set up networking/WiFi/Static IP for more detail.

  • Fresh install of rasberrian, new regular user can view the file without sudo via terminal
