Javascript: Equivalent of PHP's hash_hmac() with RAW BINARY output?
This is explained in their documentation. Try this:
var hash = CryptoJS.HmacSHA256("Message", "Secret Passphrase");
var base64 = hash.toString(CryptoJS.enc.Base64);
You need to include http://crypto-js.googlecode.com/svn/tags/3.0.2/build/components/enc-base64-min.js for this. If you didn't include this, CryptoJS.enc.Base64 will be undefined and fallback to the default.
Working demo: http://jsfiddle.net/ak5Qm/
PHP:
base64_encode(hash_hmac('sha256', $value, $key, true));
Nodejs equivalent:
const crypto = require('crypto');
let token = crypto.createHmac("sha256", key).update(value).digest().toString('base64');
php code
echo base64_encode(hash_hmac('SHA1', 'shanghai', '0', true).'beijing');
php output

node code
var crypto = require('crypto');
var buf1 = crypto.createHmac("sha1", "0").update("shanghai").digest();
var buf2 = Buffer.from('beijing');
console.log(Buffer.concat([buf1, buf2]).toString('base64'));
