Don,
   
  Thanks.
  I have  package can translate wep passphrase to wep key.
  May I use it for wpa passphrase or I have to copy codes from wpa_passphrase and let wpa_passphrase to translate to wpa key?

You don't push the passphrase to the driver, you hash the passphrase
with wpa_passphrase to get the key and you push the key down to the
driver using SIOCSIWENCODEEXT. Drivers certainly shouldn't be accepting
passphrases unless they are smoking really, really unholy crack.
