(PowerBuilder) 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.

loo_Crypt = create oleobject
// Use "Chilkat_9_5_0.Crypt2" for versions of Chilkat < 10.0.0
li_rc = loo_Crypt.ConnectToNewObject("Chilkat.Crypt2")
if li_rc < 0 then
    destroy loo_Crypt
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// The "ps" is the WPA passphrase
ls_Pw = "password"
ls_PwCharset = "ansi"

// Hash algorithms may be: sha1, md2, md5, etc.
ls_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"
ls_SsidHex = "414243"

// The WPA key calculation will always use 4096 iterations.
li_IterationCount = 4096

// The WPA hex output should be 256 bits.
li_OutputBitLen = 256

// Indicate that "hex" is to be returned.
ls_Enc = "hex"

ls_WpaHexKey = loo_Crypt.Pbkdf2(ls_Pw,ls_PwCharset,ls_HashAlg,ls_SsidHex,li_IterationCount,li_OutputBitLen,ls_Enc)
