需要与 crypto.createHmac 方法的这个特定实现等效的浏览器

Question

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?

Answer 1

You can try to use crypto-browserify .

It's a reimplementation of crypto , made it so that it can run on the Browser.

Answer 2

An HMAC can be determined by most crypto libraries, eg 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'));
