12 aircrack-ng is a 802.11 WEP / WPA-PSK key cracker. It implements the
13 so-called Fluhrer - Mantin - Shamir (FMS) attack, along with some new
14 attacks by a talented hacker named KoreK. When enough encrypted packets
15 have been gathered, aircrack-ng can almost instantly recover the WEP
16 key.

19 -H, --help
20 Shows the help screen.
21 Common options:
23 -a <amode>
25 Force the attack mode, 1 or wep for WEP and 2 or wpa for WPA-
26 PSK.
27 -e <essid>
29 Select the target network based on the ESSID. This option is
30 also required for WPA cracking if the SSID is cloacked.
31 -b <bssid>
33 Select the target network based on the access point MAC address.
34 -p <nbcpu>
36 Set this option to the number of CPUs to use (only available on
37 SMP systems). By default, it uses all available CPUs
38 -q If set, no status information is displayed.
40 Static WEP cracking options:
42 -c Search alpha-numeric characters only.
44 -t Search binary coded decimal characters only.
46 -h Search the numeric key for Fritz!BOX
48 -d <mask>
50 Specify mask of the key. For example: A1:XX:CF
51 -m <maddr>
53 Only keep the IVs coming from packets that match this MAC
54 address. Alternatively, use -m ff:ff:ff:ff:ff:ff to use all and
55 every IVs, regardless of the network (this disables ESSID and
56 BSSID filtering).
57 -n <nbits>
59 Specify the length of the key: 64 for 40-bit WEP, 128 for
60 104-bit WEP, etc., until 512 bits of length. The default value
61 is 128.
62 -i <index>
64 Only keep the IVs that have this key index (1 to 4). The default
65 behaviour is to ignore the key index in the packet, and use the
66 IV regardless.
67 -f <fudge>
69 By default, this parameter is set to 2. Use a higher value to
70 increase the bruteforce level: cracking will take more time, but
71 with a higher likelihood of success.
72 -k <korek>
74 There are 17 KoreK attacks. Sometimes one attack creates a huge
75 false positive that prevents the key from being found, even with
76 lots of IVs. Try -k 1, -k 2, ... -k 17 to disable each attack
77 selectively.
78 -x or -x0
80 Disable last keybytes bruteforce (not advised).
81 -x1 Enable last keybyte bruteforcing (default)
83 -x2 Enable last two keybytes bruteforcing.
85 -X Disable bruteforce multithreading (SMP only).
87 -s Shows ASCII version of the key at the right of the screen
89 -y This is an experimental single brute-force attack which should
91 only be used when the standard attack mode fails with more than
92 one million IVs.
93 -z Uses PTW (Andrei Pyshkin, Erik Tews and Ralf-Philipp Weinmann)
95 attack.
96 WPA-PSK cracking options:
98 -w <words>
100 Path to a dictionary file for wpa cracking. Specify "-" to use
101 stdin.
