Create a utility function to hash a password coming from the user.

And another utility to verify if a received password matches the hash stored.

And another one to authenticate and return a user.

  Either the well was very deep, or she fell very slowly, for she
had plenty of time as she went down to look about her and to
wonder what was going to happen next.  First, she tried to look
down and make out what she was coming to, but it was too dark to
see anything; then she looked at the sides of the well, and
noticed that they were filled with cupboards and book-shelves;
here and there she saw maps and pictures hung upon pegs.  She

3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function (`iterfile`).

    So, it is a generator function that transfers the "generating" work to something else internally.

El orden de cada diccionario de metadata de etiqueta también define el orden mostrado en la interfaz de documentación.

Por ejemplo, aunque `users` iría después de `items` en orden alfabético, se muestra antes porque agregamos su metadata como el primer diccionario en la list.

## URL de OpenAPI

Por defecto, el esquema OpenAPI se sirve en `/openapi.json`.

Pero puedes configurarlo con el parámetro `openapi_url`.

* **Define requirements**: from request path parameters, query parameters, headers, bodies, dependencies, etc.
* **Convert data**: from the request to the required type.
* **Validate data**: coming from each request:
    * Generating **automatic errors** returned to the client when the data is invalid.
* **Document** the API using OpenAPI:
    * which is then used by the automatic interactive documentation user interfaces.

### iptables

For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow
access to port 9000

```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```

	p.diskID.Store(&id)
}

func (p *xlStorageDiskIDCheck) checkDiskStale() error {
	if *p.diskID.Load() == emptyDiskID {
		// For empty disk-id we allow the call as the server might be
		// coming up and trying to read format.json or create format.json
		return nil
	}
	storedDiskID, err := p.storage.GetDiskID()
	if err != nil {
		// return any error generated while reading `format.json`
		return err
	}

across firewall start, restart or reload. Finally reload the firewall for changes to take effect. ```sh firewall-cmd --reload ``` ### iptables For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow access to port 9000 ```sh iptables -A INPUT -p tcp --dport 9000 -j ACCEPT service iptables restart ``` Below command enables all incoming traffic to ports ranging from 9000 to 9010. ```sh iptables -A INPUT...
