# Chiffrement des campagnes

Les campagnes utilisent des identifiants personnels tels que des e-mails ou des numéros de téléphone afin de pouvoir envoyer vos invitations aux destinataires. En utilisant le chiffrement des campagnes, vous pouvez définir un [classification des données](/fr/data-encryption/data-classification.md) pour chacune de vos campagnes afin de chiffrer et sécuriser les destinataires de la campagne.

{% hint style="warning" %}
Le destinataire ne sera entièrement chiffré en mode restreint qu’une fois que l’e-mail aura été envoyé et que le destinataire aura été retiré de la file d’attente. En attendant, le destinataire sera marqué comme sensible.  
{% endhint %}

## ⚠️ Limitations

Les campagnes restreintes ne peuvent pas avoir de rappels, car il n’est pas possible de revenir en interne sur le chiffrement pour récupérer les destinataires une fois les invitations envoyées.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ngsurvey.com/fr/data-encryption/campaign-encryption.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
