# Tipos de intercambios de claves

Cuando intercambiamos claves a través de la aplicación Gestión de claves de intercambio, podemos realizar 1 ó 2 tipos de intercambios:

* Inicialmente, 2 entidades, se intercambian una clave RSA, (parte pública), en cada sentido y en claro. Esto se hace siempre, independientemente de que lo que luego intercambien sean claves DES.
* Posteriormente esos 2 extremos:

> A partir del intercambio inicial, cuando se intercambien nuevas claves públicas RSA, todos los envíos irán firmados con alguna privada de la que tengamos constancia que se ha enviado al remoto la pública asociada correspondiente. Es decir, en el segundo intercambio, al menos se podrá firmar con la inicial, en el tercero con la inicial o con la segunda y así sucesivamente.

# Agent Instructions

## 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://docs.editran.onesait.com/documentacion-editran/copy-of-privado-editran-v5.3-cics/gestor-de-claves/introduccion/tipos-de-intercambios-de-claves.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.
