### Casos de uso: servicio externo

Un ejemplo podría ser que tienes un proveedor de autenticación externo al que necesitas llamar.

Le envías un token y te devuelve un usuario autenticado.

Este proveedor podría estar cobrándote por cada request, y llamarlo podría tomar más tiempo adicional que si tuvieras un usuario de prueba fijo para los tests.

   * is big-endian or little-endian depends on the byte order of {@link #asBytes}. This may be

   * since everything else in the hashing API uniformly treats multibyte values as little-endian.
