var encoded = encodeURIComponent(uri); 
var now = new Date(); 
var week = 60*60*24*7;
var ttl = Math.round(now.getTime() / 1000) + week;
var signature = encoded + '\n' + ttl; 
var signatureUTF8 = utf8.encode(signature); 
var hash = crypto.createHmac('sha256', saKey).update(signatureUTF8).digest('base64'); 
return 'SharedAccessSignature sr=' + encoded + '&sig=' +  
    encodeURIComponent(hash) + '&se=' + ttl + '&skn=' + saName; 
 }
