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

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

If your database is stolen, the thief won't have your users' plaintext passwords, only the hashes.

So, the thief won't be able to try to use those same passwords in another system (as many users use the same password everywhere, this would be dangerous).

Pero no puedes convertir del galimatías al password.

##### Por qué usar hashing de passwords { #why-use-password-hashing }

Si tu base de datos es robada, el ladrón no tendrá los passwords en texto plano de tus usuarios, solo los hashes.

Entonces, el ladrón no podrá intentar usar esos mismos passwords en otro sistema (como muchos usuarios usan el mismo password en todas partes, esto sería peligroso).

##### Porque usar hashing de senha { #why-use-password-hashing }

Se o seu banco de dados for roubado, o ladrão não terá as senhas em texto simples dos seus usuários, apenas os hashes.

Assim, o ladrão não poderá tentar usar essas mesmas senhas em outro sistema (como muitos usuários usam a mesma senha em todos os lugares, isso seria perigoso).
