So, I have this piece of code that's written in Node.js
crypto.createHmac('sha256', secret).update(orderedParams).digest('hex') I wish to bring this piece of code in the browser but that doesn't work since the 'crypto' library is not supported on the browser. Can somebody just help me re-create the same method in the browser?
An HMAC can be determined by most crypto libraries, e.g. CryptoJS or WebCrypto API.
The following example uses CryptoJS:
var secret = 'my secret'; var orderedParams = 'the ordered params'; // Short var hmac3 = CryptoJS.HmacSHA256(orderedParams, secret).toString(); console.log(hmac3.replace(/(.{48})/g,'$1\n')); // Progressive var hmac2 = CryptoJS.algo.HMAC.create(CryptoJS.algo.SHA256, secret).update(orderedParams).finalize().toString(); console.log(hmac2.replace(/(.{48})/g,'$1\n'));<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.0.0/crypto-js.min.js"></script>
You can try to use crypto-browserify.
It's a reimplementation of crypto, made it so that it can run on the Browser.
Can't resolve 'stream' in node_modules/cipher-base.
