WPA Key Calculation from PassPhrase to Hex

See more Encryption Examples

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

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

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

set crypt = CreateObject("Chilkat.Crypt2")

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

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

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

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

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

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

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

outFile.WriteLine(wpaHexKey)

outFile.Close
