its the mathematical hash of the wifi password combined with your network name (ssid ). When you connect to a wifi network, its not really the password that connects you to the wifi network. i use PSKs all the time, because it saves me from typing special characters if someone asks you for your wifi password, give them the key instead. the preshared key can be used as the password. The hash as i call it, is actually called the PRE SHARED KEY. This is why you don't use common SSID names like 'NETGEAR' because those hash tables are available or download for example, a wifi network name of appleinsider, and a password ' appleinsiderpassword ', generates a hash of ' e70f772ac2efd170dc485b19f19ac9a237cdbfbdc816a402fd5a3d9b08a94c52 ' and its that hexicimal string that actually connects you to the wifi network.

try it sometime.Įrase your hard disk completely, and do an internet restore, and it will connect to your wifi!! and if you do a pram reset, it will then ask you for the login credentials becauseĪs far as mongo bongos reply goes. A better article would of been make sure you erase your pram when you sell your mac, because thats another place where macs store wifi passwords.
