How to use Scapy to determine WPA Encryption?

To fix the issue you can do The code you are using assumes the info tag exist on all dot11 elements. This used to be true when most of them were not implemented. Nowadays, scapy is supporting some more (such as WPA Microsoft vendor-specific), which do not. The code you linked is now outdated
However in (very) latest scapy development version, there is now a special function that will always stay consistent: network_stats which implement the code you showed:
code :
data = b'\x00\x00\x12\x00.H\x00\x00\x00\x02\x8f\t\xa0\x00\x01\x01\x00\x00\x80\x00\x00\x00\xff\xff\xff\xff\xff\xffDH\xc1\xb7\xf0uDH\xc1\xb7\xf0u\x10\xb7\x00\x00\x00\x00\x00\x00\x00\x00\x90\x01\x11\x00\x00\x06SSID76\x01\n\x82\x84\x0c\x12\x18$0H`l\x03\x01\x080\x18\x01\x00\x00\x0f\xac\x04\x02\x00\x00\x0f\xac\x04\x00\x0f\xac\x02\x01\x00\x00\x0f\xac\x02\x0c\x00'
pkt = RadioTap(data)
nstats = pkt[Dot11Beacon].network_stats()
assert nstats == {
   'channel': 8,
   'crypto': {'WPA2'},
   'rates': [130, 132, 12, 18, 24, 36, 48, 72, 96, 108],
   'ssid': 'SSID76'

scapy's contrib is missing after installing scapy on both windows and fedora

scapy's contrib is missing after installing scapy on both windows and fedora

hop of those help? Looking at the zip file provided at http://www.secdev.org/projects/scapy/ I don't see the contrib folder. For some reason it is not bundled into the zip.
You should be able to download the source of Scapy 2.2.0 directly and install that using setup.py, which does has the contrib folder.
code :
hg clone https://bitbucket.org/secdev/scapy
cd scapy
hg update -r v2.2.0
packages=['scapy','scapy/arch', 'scapy/arch/windows', 
'scapy/layers','scapy/asn1','scapy/tools','scapy/modules', 'scapy/crypto', 
'scapy/contrib' ]

wish helps you OK, at the beginning I put the fields behind the encryption in a packet, and do all the encryption magic in post_build (encrypt) and pre_dissect (decrypt), but that was really tricky... so Instead I created another packet (EncryptedPacket) which overloads addfield and getfield to do all the encryption stuff, this solution is much cleaner and nicer then the previous one. I will add examples later.

may help you . In Scapy, when you use the / operator the operand on the left encapsulates or places the operand on the right as it's data, or underlayer. It's what will come next in the packet.
Your problem is your sending line -

this one helps. I'm trying to create a beacon frame without any encryption in scapy. So when I'm sending the frame, the access point should be shown as open. , Clear the privacy field in beacon editing this line:
code :
beacon = Dot11Beacon(cap='ESS')

I think the issue was by ths following , Based on airodump-ng code (aicrack-ng suite), the information you're looking for is inside specific Dot11Elt layers. By the way in your code, you get SSID and channel by guessing that they are located in the first and third Dot11Elt layers, which seems to be the case, but I don't think it's mandatory.
This code should do the work:
