wpa_supplicant.conf

i wanted to check the password of my niegbours wifi (which i had acces to,cause he entered it once on my phone :p :p)
so i got phone rooted
everything was done fine
untill i opened the wpa_supplicant.conf
which was to display sth like this
network={
ssid="SomeWifiNetwork"
psk="MyPlaintextPassword"
key_mgmt=WPA-PSK
priority=1
but instead the psk is shown as
psk=106f6500210e7058f145171eade3398c
what sort of code string hex or whatever is this??
