Identifying proto

[Paresh Sawant]

Hi,

I'm trying to figure out how wpa_supplicant identifies the proto.

It seems if the scanned BSS  description contains RSN IE ( # 0x30) then it
is WPA2, if it has WPA IE (# 0xDD) it is WPA, else it is WEP.

Is it a correct way to identify the proto?

In case if the BSS is found to be WEP then is there a way to know what is
encryption supported i.e whether it is WEP-40 or WEP-104?


Thanks
