Comment 5 for bug 477323

diff wpa wpa-psk shows:
1c1
< name = WPA 1/2 (Passphrase)
---
> name = WPA 1/2 (Preshared Key)
4c4
< require key *Key
---
> require apsk *Preshared_Key
14c14
< psk=$_PSK
---
> psk="$_APSK"

So I think using WPA 1/2 (Passphrase) would work in my case. But I don't understand the philosophy! Why do i have to enter a hexadecimal ("non typical passphrase") as a passphrase? I thought passphrase is for passphrases like <kfjfujfHdjfdkfj> and preshared is for keys like 0x18d348a2..... Am I completely wrong with this?
