# Seguro

QUIC es siempre seguro. No hay una versión texto claro del protocolo, por lo que negociar una conexión QUIC significa hacer criptografía y seguridad con TLS 1.3. Como se mencionó anteriormente, esto evita la osificación, así como otros tipos de bloqueos y tratamientos especiales, además de asegurar que QUIC tiene todas las propiedades seguras de HTTPS que los usuarios de la web han llegado a esperar y desear.

Sólo hay unos pocos paquetes iniciales de intercambio de información que se envían en claro antes de que los protocolos de encriptación hayan sido negociados.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://http3-explained.haxx.se/es/why-quic/why-secure.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
