WPA keys' hex values are not 26 characters long.  However, WEP-104 keys
are.  (WEP-104 is also sometimes called WEP-128 by vendors that try to
make it seem better than it really is.  It only uses 104 bits' worth of
key material.  104 bits is 13 bytes, which is 26 hex characters.)

Yep, that's right.  WPA-PSK keys are 32 bytes (256 bits) long, which is
64 characters.  There's also a hash function that will combine an ASCII
string (<=63 characters' worth) with the SSID to generate a 256-bit key.

It's a WEP(-104) key, not a WPA key.  :-)
