Hi Team,

I am trying to generate HMAC using below on JS and it gives output :

const crypto = require('crypto');

const secret = Buffer.from('DDASCD');
const hash = crypto.createHmac('sha256', secret).update('446578').digest('base64');
console.log(hash);  //output =>   D+wGGPQkAlGnM9AuBTqRieTN+Y++FixBki500ptR2VU=

When tired on Datapower/APIC above same code it is giving me error 256 bit key required.

I want same output from datapower as above , please help me here.

our client is using same secret key to generate hash , we have to match the same hash in incoming request..
