I am trying to convert the below javascript code into apex. The javascript code is below-

timestamp = Math.round((new Date()).getTime() / 1000);
var method = request.method;
var path = request.url.replace(/^.*\/\/[^\/]+/, '');
var prehash = timestamp + '-' + method + '-' + path;
var secret = 'xxxxx';
var username = '';
var hash = CryptoJS.HmacSHA256(prehash, secret);

The hash being generated here looks like -


The apex code is below-

string timestmp = String.valueof((DateTime.now().getTime())/1000);
string method ='POST';
string testurl='';
string path = testurl.replace('/^.*\\/\\/[^\\/]+/', '');
string prehash = timestmp + '-' + method + '-' + path;
string secret = 'xxxxx';
string username = '';
String algorithmName='HmacSHA256';
Blob hmacData = Crypto.generateMac(algorithmName, Blob.valueOf(prehash), Blob.valueOf(secret));
string hash = EncodingUtil.base64Encode(hmacData);

The hash being generated by apex looks like -


I want the hash being generated by apex to be similar in format to the hash being generated by javascript. Can anyone pls advice how should I modify my code to meet my requirement.


The output of your JavaScript is hexadecimal text (Base 16). The output of your Apex is Base64.

To generate a hexadecimal string in Apex, use EncodingUtil.convertToHex(blob) rather than base64Encode().
