# Password ile OAuth2 (ve hashing), JWT token'ları ile Bearer { #oauth2-with-password-and-hashing-bearer-with-jwt-tokens }

Artık tüm security flow elimizde olduğuna göre, uygulamayı gerçekten güvenli hâle getirelim: <abbr title="JSON Web Token'lar">JWT</abbr> token'ları ve güvenli password hashing kullanacağız.

Bu kodu uygulamanızda gerçekten kullanabilirsiniz; password hash'lerini veritabanınıza kaydedebilirsiniz, vb.

/// tip | Consejo

Podrías necesitar que el parámetro contenga `/home/johndoe/myfile.txt`, con una barra inclinada (`/`) inicial.

En ese caso, la URL sería: `/files//home/johndoe/myfile.txt`, con una doble barra inclinada (`//`) entre `files` y `home`.

/// tip

You might need the parameter to contain `/home/johndoe/myfile.txt`, with a leading slash (`/`).

In that case, the URL would be: `/files//home/johndoe/myfile.txt`, with a double slash (`//`) between `files` and `home`.

With **FastAPI**, by using short, intuitive and standard Python type declarations, you get:

Blocking APIs may be inefficient because you hold a thread idle while waiting on the network. Threads are expensive because they have both a memory overhead and a context-switching overhead.

## Opsiyonel Dosya Upload { #optional-file-upload }

Standart type annotation’ları kullanıp varsayılan değeri `None` yaparak bir dosyayı opsiyonel hale getirebilirsiniz:

{* ../../docs_src/request_files/tutorial001_02_an_py310.py hl[9,17] *}

## Ek Metadata ile `UploadFile` { #uploadfile-with-additional-metadata }

```console
// Go to the home directory
$ cd
// Create a directory for all your code projects
$ mkdir code
// Enter into that code directory
$ cd code
// Create a directory for this project
$ mkdir awesome-project
// Enter into that project directory
$ cd awesome-project
```

Result (German):

```console
// Gehe zum Home-Verzeichnis
$ cd
