Paste a received signature to verify it against the currently generated HMAC.

const crypto = require('crypto');
const hmac = crypto.createHmac(
  'sha256', 
  'secret'
);
hmac.update('message');
console.log(hmac.digest('hex'));
import hmac

sig = hmac.new(
    b'secret',
    b'message',
    hashlib.sha256
).hexdigest()
print(sig)
$sig = hash_hmac(
    'sha256', 
    'message',
