var text = (verb || "").toLowerCase() + "\n" + (resourceType || "").toLowerCase() + "\n" + (resourceId || "") + "\n" + now.toLowerCase() + "\n" + "" + "\n";
var key = CryptoJS.enc.Base64.parse(pm.variables.get("masterKey"));
var signature = CryptoJS.HmacSHA256(text, key).toString(CryptoJS.enc.Base64);
 
var MasterToken = "master";
var TokenVersion = "1.0";
var authToken = encodeURIComponent("type=" + MasterToken + "&ver=" + TokenVersion + "&sig=" + signature);
