`MultipartBody.Builder` can build sophisticated request bodies compatible with HTML file upload forms. Each part of a multipart request body is itself a request body, and can define its own headers. If present, these headers should describe the part body, such as its `Content-Disposition`. The `Content-Length` and `Content-Type` headers are added automatically if they're available.

Crea un "contexto" de PassLib. Este es el que se usará para hacer el hash y verificar las contraseñas.

/// tip | Consejo

El contexto de PassLib también tiene funcionalidad para usar diferentes algoritmos de hashing, incluidos los antiguos obsoletos solo para permitir verificarlos, etc.

Ao invés disso, sendo um sistema "assíncrono", uma vez finalizada, a tarefa pode esperar na fila um pouco (alguns microssegundos) para que o computador / programa finalize o que quer que esteja fazendo, e então volte para pegar o resultado e continue trabalhando com ele.

## OAuth2

OAuth2 é uma especificação que define várias formas para lidar com autenticação e autorização.

Ela é bastante extensiva na especificação e cobre casos de uso muito complexos.

Ela inclui uma forma para autenticação usando “third party”/aplicações de terceiros.
