createHMAC( algorithm, secret )
Note
A module with a better and standard API exists.
The new k6/experimental/webcrypto API partially implements the WebCryptoAPI, supporting more features than k6/crypto.
Creates a HMAC hashing object that can then be fed with data repeatedly, and from which you can extract a signed hash digest whenever you want.
Returns
Example
import crypto from 'k6/crypto';
export default function () {
console.log(crypto.hmac('sha256', 'a secret', 'my data', 'hex'));
const hasher = crypto.createHMAC('sha256', 'a secret');
hasher.update('my ');
hasher.update('data');
console.log(hasher.digest('hex'));
}
The above script should result in the following being printed during execution:
