First of all, with encryption off does the interface work?
It's best to know that you can function on the network and can get an IP 
address before you add network encryption to the mix. 

One of the things that wpa_supplicant does is it keeps the keys for you in a 
file.  You first have to run wpa_passphrase to convert the wpa passphrase 
into hex.  The output of the command will give you a stanza which you can cut 
& paste directly into the wpa_supplicant.conf file. 


The output from wpa_passphrase looks something like this:

network={
        ssid="myessid"
        #psk="passphrase"
        psk=generated hexstring
}
