WPA PMK Generator

Description

Generates plainmasterkeys from essid and password for use with hashcat hash-mode 2501
Also can output to Hashcat and John format to use with mode 12000 - PBKDF2-HMAC-SHA1
WPA / WPA2 / WPA3 PMK

Checklist

• Generates WPA PMK
• Can be used in hashcat mode 2501
• Exports to Hashcat mode 12000 and John pbkdf2-hmac-sha1 via wlanwkp2hcx

Technologies:

Visual Studio 15.8
Net Framework 4.6.1
Cygwin v2.893

Algorithm

PMK = PBKDF2(HMAC−SHA1, PSK, SSID, 4096, 256)

The PMK is a SHA1 hashing function with HMAC as the message authentication code.
The PMK is generated from 4096 iterations of the hashing method and creates a 256-bit PMK
which is 64 hexadecimal characters and where each hexadecimal character represents 4 bits.

RFC2898
