## Password hashing { #password-hashing }

"Hashing" means converting some content (a password in this case) into a sequence of bytes (just a string) that looks like gibberish.

Whenever you pass exactly the same content (exactly the same password) you get exactly the same gibberish.

But you cannot convert from the gibberish back to the password.

### Why use password hashing { #why-use-password-hashing }

    assertThat(union(newHashSet(1, 2), newHashSet(2, 3)).copyInto(new HashSet<>()))
        .containsExactly(1, 2, 3);
    assertThat(intersection(newHashSet(1, 2), newHashSet(2, 3)).copyInto(new HashSet<>()))
        .containsExactly(2);
    assertThat(difference(newHashSet(1, 2), newHashSet(2, 3)).copyInto(new HashSet<>()))
        .containsExactly(1);

Nunca deberías guardar passwords en texto plano, así que, usaremos el sistema de hash de passwords (falso).

Si los passwords no coinciden, devolvemos el mismo error.

"Hacer hash" significa: convertir algún contenido (un password en este caso) en una secuencia de bytes (solo un string) que parece un galimatías.
