    Example #1 sodium_crypto_generichash_final() example

    <?php
    $messages     = [random_bytes(32), random_bytes(32), random_bytes(16)];
    $state = sodium_crypto_generichash_init('', 32);
    foreach (    $messages as $message) {
    sodium_crypto_generichash_update($state, $message);
    }

    $final = sodium_crypto_generichash_final($state, 32);
    var_dump(sodium_bin2hex($final));

    $allAtOnce = sodium_crypto_generichash(implode('', $messages));
    var_dump(sodium_bin2hex($allAtOnce));
    ?>
