(Xojo Plugin) WPA Key Calculation from PassPhrase to Hex

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

// 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
pw = "password"
Dim pwCharset As String
pwCharset = "ansi"

// Hash algorithms may be: sha1, md2, md5, etc.
Dim hashAlg As String
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"
Dim ssidHex As String
ssidHex = "414243"

// The WPA key calculation will always use 4096 iterations.
Dim iterationCount As Int32
iterationCount = 4096

// The WPA hex output should be 256 bits.
Dim outputBitLen As Int32
outputBitLen = 256

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

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