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

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

oCrypt := CreateObject("Chilkat.Crypt2")

//  The "ps" is the WPA passphrase
cPw := "password"
cPwCharset := "ansi"

//  Hash algorithms may be: sha1, md2, md5, etc.
cHashAlg := "sha1"

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

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

//  The WPA hex output should be 256 bits.
nOutputBitLen := 256

//  Indicate that "hex" is to be returned.
cEnc := "hex"
