(VB.NET UWP/WinRT) WPA Key Calculation from PassPhrase to Hex

Demonstrates how to calculate a WPA key from a passprhase and network SSID.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim crypt As New Chilkat.Crypt2

Dim wpaHexKey As String

' The "ps" is the WPA passphrase
Dim pw As String = "password"
Dim pwCharset As String = "ansi"

' Hash algorithms may be: sha1, md2, md5, etc.
Dim hashAlg As String = "sha1"

' Specify the SSID in hex:
' For example, if the SSID is "ABC", then the 
' hex values for these us-ascii chars is "414243"
Dim ssidHex As String = "414243"

' The WPA key calculation will always use 4096 iterations.
Dim iterationCount As Integer = 4096

' The WPA hex output should be 256 bits.
Dim outputBitLen As Integer = 256

' Indicate that "hex" is to be returned.
Dim enc As String = "hex"

wpaHexKey = crypt.Pbkdf2(pw,pwCharset,hashAlg,ssidHex,iterationCount,outputBitLen,enc)

Debug.WriteLine(wpaHexKey)
