Duplicate Java Secure Token Creation

Demonstrates how to duplicate some Java code that creates an RSA signature to create a base64 token. AutoIt

Local $bSuccess = False

; This requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

; This example duplicates the following Java code:

; public X509Certificate2 cert = new X509Certificate2(@"Some path to p12/p12file_name.p12","Password_for_p12"); 
; 
; public string GenerateSignToken(double timeValidityMin){ 
;   string equalsSign = ":="; 
;   string timeCreated = DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ss.fffzzz"); 
;   string tokenTimeInfo = "validityTimeMinutes" + equalsSign + timeValidityMin + ";"+"timeCreated" + equalsSign + timeCreated; 
;   string signature = SignData(tokenTimeInfo); 
;   string secureToken = tokenTimeInfo + ";" + "signature" + equalsSign + signature; 
;   return Base64UrlEncode(secureToken); 
; } 
;  
; public string SignData(string stringToSign){ 
;   byte[] dataToSign = Encoding.UTF8.GetBytes(stringToSign); 
;   RSACryptoServiceProvider privKey = (RSACryptoServiceProvider)cert.PrivateKey; 
;   CspKeyContainerInfo containerInfo = new RSACryptoServiceProvider().CspKeyContainerInfo; 
;   CspParameters cspparams = new CspParameters(containerInfo.ProviderType, containerInfo.ProviderName, privKey.CspKeyContainerInfo.KeyContainerName); 
;   privKey = new RSACryptoServiceProvider(cspparams); 
;   string id = CryptoConfig.MapNameToOID("SHA256"); 
;   byte[] sign = privKey.SignData(dataToSign, id); 
;   bool res = privKey.VerifyData(dataToSign, id, sign); 
;   return Convert.ToBase64String(sign).Replace('+', '-').Replace('/', '_').Replace("=", "");
