Issue with HMAC created using Crypto-JS

[PradeepAnde]

Hi,
We are using Crypto-js to create HMAC and send the request to the Proxy.

The HMAC which is created using JAVA "hmac-edge-callout.jar" is different.

       data = CryptoJS.enc.Utf8.parse(data);
        var hashSign = CryptoJS.HmacSHA512(data, apiSecret); 

var buffer = new Buffer(hashSign);
var toBase64 = buffer.toString('base64');

Is it an HMAC 512 in the server? I think it might be HMAC 256. Can you check?

I should have mentioned:

I've used crypto-JS in multiple different clients against this code and it works.
But you need to make sure the bit strength is correct on both sides.

We are using SHA512. Below is the code. Can you please post cryptoJS code.

We are creating HMAC using crypto-JS and sending the request to Proxy. We have created a Java call out using "hmac-edge-callout.jar" to verify the HMAC.

I am new to APIGEE, any suggestions will be helpful. Please find below code.
