(AutoIt) URL Signing for Google Maps API
Demonstrates how to sign a URL for the Google Maps API.
; This example assumes the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.
$oCrypt = ObjCreate("Chilkat.Crypt2")
; The output will be modified Base64.
; Modified Base64 for URLs replaces the '+' and '/' characters
; of standard Base64 with '-' and '_' respectively, so that these
; Base64 signatures no longer need to be URL-encoded.
$oCrypt.EncodingMode = "modBase64"
; Set the hash algorithm to sha-1
$oCrypt.HashAlgorithm = "sha-1"
Local $sig
; Set the HMAC key (this is the private key provided by Google)
$oCrypt.SetHmacKeyEncoded "vNIXE0xscrmjlyV-12Nj_BvUPaw=","modBase64"
; Compute the URL signature
$sig = $oCrypt.HmacStringENC("/maps/api/geocode/json?address=New+York&sensor=false&client=clientID")
; The result should be KrU1TzVQM7Ur0i8i7K3huiw3MsA=
ConsoleWrite($sig & @CRLF)
