Sie können jedoch nicht vom Kauderwelsch zurück zum Passwort konvertieren.

### Warum Passwort-Hashing verwenden { #why-use-password-hashing }

Wenn Ihre Datenbank gestohlen wird, hat der Dieb nicht die Klartext-Passwörter Ihrer Benutzer, sondern nur die Hashes.

Pero no puedes convertir del galimatías de nuevo a la contraseña.

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

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

이는 전체 앱에서 사용해야 하는 **자원**을 설정하고, 요청 간에 **공유되는** 자원을 설정하고, 그리고/또는 이후에 **정리**하는 데 매우 유용할 수 있습니다. 예를 들어, 데이터베이스 연결 풀 또는 공유 머신러닝 모델을 로드하는 경우입니다.

## 사용 사례 { #use-case }

먼저 **사용 사례** 예시로 시작한 다음, 이를 어떻게 해결할지 살펴보겠습니다.

요청을 처리하는 데 사용하고 싶은 **머신러닝 모델**이 있다고 상상해 봅시다. 🤖

동일한 모델이 요청 간에 공유되므로, 요청마다 모델이 하나씩 있거나 사용자마다 하나씩 있는 등의 방식이 아닙니다.

Podría ser llamada como:

```Python
oauth2_scheme(some, parameters)
```

Así que, puede usarse con `Depends`.

### Úsalo { #use-it }

Ahora puedes pasar ese `oauth2_scheme` en una dependencia con `Depends`.

### Pourquoi utiliser le hachage de mot passe { #why-use-password-hashing }

Si votre base de données est volée, le voleur n'aura pas les mots de passe en clair de vos utilisateurs, seulement les hachages.

Используйте чат только для прочих общих бесед.

### Не используйте чат для вопросов { #dont-use-the-chat-for-questions }

Имейте в виду, что в чатах, благодаря "свободному общению", легко задать вопросы, которые слишком общие и на которые сложнее ответить, поэтому Вы можете не получить ответы.
