Aquí estamos usando `Query()` porque este es un **parámetro de query**. Más adelante veremos otros como `Path()`, `Body()`, `Header()`, y `Cookie()`, que también aceptan los mismos argumentos que `Query()`.

        final int targetInfoLength = targetInfo != null ? targetInfo.length : 0;
        final byte[] temp = new byte[28 + targetInfoLength + 4];

        Encdec.enc_uint32le(0x00000101, temp, 0); // Header
        Encdec.enc_uint32le(0x00000000, temp, 4); // Reserved
        Encdec.enc_uint64le(nanos1601, temp, 8);
        System.arraycopy(clientChallenge, 0, temp, 16, 8);
