pixiewps - Man Page

Offline Wi-Fi Protected Setup bruteforce tool


Pixiewps is a tool written in C used to bruteforce offline the WPS PIN method exploiting the low or non-existing entropy of some Access Points, the so-called "pixie-dust attack".

It is meant for educational purposes only.


pixiewps <arguments>


Required Arguments

-e, --pke

Enrollee's DH public key, found in M1.

-r, --pkr

Registrar's DH public key, found in M2. It can be avoided by specifying --dh-small in both Reaver and pixiewps.

pixiewps -e <pke> -s <e-hash1> -z <e-hash2> -a <authkey> -n <e-nonce> -S

-s, --e-hash1

Enrollee's hash 1, found in M3. It's the hash of the first half of the PIN.

-z, --e-hash2

Enrollee's hash 2, found in M3. It's the hash of the second half of the PIN.

-a, --authkey

Authentication session key. Although for this parameter a modified version of Reaver or Bully is needed, it can be avoided by specifying small Diffie-Hellman keys in both Reaver and pixiewps and supplying --e-nonce, --r-nonce and --e-bssid.

pixiewps -e <pke> -s <e-hash1> -z <e-hash2> -S -n <e-nonce> -m <r-nonce> -b <e-bssid>

-n, --e-nonce

Enrollee's nonce, found in M1.

Optional Arguments

-m,  --r-nonce

Registrar's nonce, found in M2. Used with other parameters to compute the session keys.

-b,  --e-bssid

Enrollee's BSSID. Used with other parameters to compute the session keys.

-S,  --dh-small (deprecated)

Small Diffie-Hellman keys. The same option must be specified in Reaver too. Some Access Points seem to be buggy and don't behave correctly with this option. Avoid using it with Reaver when possible.

-v,  --verbosity

Verbosity level 1-3, 1 is quietest, default is 3.


Display a simple help usage screen.


Display verbose help.

-V,  --version

Display version and other information.

--mode N[,... N]

Select modes, comma separated (experimental modes are not used unless specified):

1 - RT/MT/CL

2 - eCos simple

3 - RTL819x

4 - eCos simplest [Experimental]

5 - eCos Knuth    [Experimental]

--start [mm/]yyyy

--end [mm/]yyyy

Starting and ending dates for mode 3, they are interchangeable.

If only one is specified, the current time will be used for the other. The earliest possible date is 01/1970, corresponding to 0 (Unix epoch time), the latest is 02/2038, corresponding to 0x7FFFFFFF. If --force is used then pixiewps will start from the current time and go back all the way to 0.

Miscellaneous Arguments

-7, --m7-enc

Encrypted settings, found in M7. Recover Enrollee's WPA-PSK and secret nonce 2. This feature only works on some Access Points vulnerable to mode 3.

pixiewps -e <pke> -r <pkr> -n <e-nonce> -m <r-nonce> -b <e-bssid> -7 <enc7> --mode 3

-5, --m5-enc

Encrypted settings, found in M5. Recover Enrollee's secret nonce 1. This option must be used in conjunction with --m7-enc. If --e-hash1 and --e-hash2 are also specified, pixiewps will also recover the WPS PIN.

pixiewps -e <pke> -r <pkr> -n <e-nonce> -m <r-nonce> -b <e-bssid> -7 <enc7> -5 <enc5> --mode 3

pixiewps -e <pke> -r <pkr> -n <e-nonce> -m <r-nonce> -b <e-bssid> -7 <enc7> -5 <enc5> --mode 3 -s <e-hash1> -z <e-hash2>


pixiewps --pke <pke> --pkr <pkr> --e-hash1 <e-hash1> --e-hash2 <e-hash2> --authkey <authkey> --e-nonce <e-nonce>

pixiewps -e <pke> -r <pkr> -s <e-hash1> -z <e-hash2> -a <authkey> -n <e-nonce>


Pixiewps was developed by wiire.

This manual page was written by Daniel Echeverry <epsilon77@gmail.com> and Samuel Henrique <samueloph@gmail.com> for the Debian project, but can be used by other projects as well.
