Use the following command to generate a private key with RSA:

```sh
openssl genrsa -out private.key 2048
```

A response similar to this one should be displayed:

```
Generating RSA private key, 2048 bit long modulus
............................................+++
...........+++
e is 65537 (0x10001)
```

Alternatively, use the following command to generate a private RSA key protected by a password:

```sh

        return dividend; // dividend < divisor
      } else {
        return dividend - divisor; // dividend >= divisor
      }
    }

    // Optimization - use signed modulus if dividend < 2^63
    if (dividend >= 0) {
      return dividend % divisor;
    }

    /*
     * Otherwise, approximate the quotient, check, and correct if necessary. Our approximation is

# Cuerpo - Modelos Anidados { #body-nested-models }

Con **FastAPI**, puedes definir, validar, documentar y usar modelos anidados de manera arbitraria (gracias a Pydantic).

## Campos de lista { #list-fields }

Puedes definir un atributo como un subtipo. Por ejemplo, una `list` en Python:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Esto hará que `tags` sea una lista, aunque no declare el tipo de los elementos de la lista.

# Modelos Adicionais { #extra-models }

Continuando com o exemplo anterior, será comum ter mais de um modelo relacionado.

Isso é especialmente o caso para modelos de usuários, porque:

* O **modelo de entrada** precisa ser capaz de ter uma senha.
* O **modelo de saída** não deve ter uma senha.
* O **modelo de banco de dados** provavelmente precisaria ter uma senha com hash.
