hmac( algorithm, secret, data, outputEncoding )
Note
A module with a better and standard API exists.

Use HMAC to sign a piece of data using a shared secret.
Returns
Example
import crypto from 'k6/crypto';
export default function () {
let hash = crypto.hmac('sha256', 'mysecret', 'hello world!', 'hex');
console.log(hash);
const binArray = [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 33];
hash = crypto.hmac('sha256', 'mysecret', new Uint8Array(binArray).buffer, 'hex');
console.log(hash);
}
The above script should result in the following being printed during execution:
