Signature Calculation

Javascript:

var timestamp = ''+(new Date()).getTime();

var secret = 'secret';

var encrypted = CryptoJS.HmacSHA1(timestamp, secret); 

encrypted = CryptoJS.enc.Base64.stringify(encrypted);

Java:

String timestamp = ""+System.currentTimeMillis(); 

String secret = "secret"

SecretKeySpec secretKeySpec = new SecretKeySpec(secret.getBytes(), "HmacSHA1"); 

Mac mac = Mac.getInstance("HmacSHA1");

mac.init(secretKeySpec);

String encrypted = Base64.getEncoder().encodeToString(mac.doFinal(timestamp.getBytes("UTF-8")));
