# Introducción

Revise [Administración y Operación](/documentacion-editran/copy-of-privado-editran-v5.3-cics/operacion/administrador-de-onesait-editran.md), Sistema Criptografía editran, (CICS) para entender antes que nada las posibilidades de la criptografía editran. De esa forma podrá enlazar a continuación con este manual, para poder interpretar correctamente el funcionamiento de la gestión de claves de intercambio.

En el modo de criptografía 3.0 y 4.0, tanto para DES como RSA, las entidades requieren intercambiar sus respectivas claves, es decir el intercambio es externo a editran.  Este intercambio se ha venido realizando de diversas formas; aplicaciones externas a editran, correo y correo electrónico, teléfono, etc., con lo que se observa en muchos casos la “debilidad del intercambio”.

## 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.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.
