Description:
Controls the interpretation of WEP keys.
Allowed values are KEY, in which case the key is either a 10- or 26-character hexadecimal string, or a 5- or 13-character ASCII password; or PASSPHRASE, in which case the passphrase is provided as a string and will be hashed using the de-facto MD5 method to derive the actual WEP key.
