$rsa = \phpseclib3\Crypt\PublicKeyLoader::load($privateKey)->withHash('sha256')->withMGFHash('sha256');
$symmetricKey = $rsa->decrypt(base64_decode($paymentData['header']['wrappedKey']));
$decodedText = \AESGCM\AESGCM::decryptWithAppendedTag($symmetricKey, str_repeat("\0", 16), base64_decode($paymentData['data']));
