# Chiffrement du téléchargement de fichiers

En utilisant le chiffrement de fichiers, vous pouvez appliquer un chiffrement à tous les fichiers téléchargés dans votre Sondage en utilisant le [champ de réponse file upload](/fr/form-management/form-designer/questions/question-types/advanced-types/file-upload.md) de type. 

Si vous attendez des fichiers hautement confidentiels de la part du Répondant, nous vous suggérons de définir la classification des données du type de réponse file upload sur [restreint](/fr/data-encryption/data-classification/restricted.md) pour une sécurité maximale. De cette façon, ngSurvey chiffrera l’intégralité du fichier à l’aide de votre clé publique PGP et vous serez la seule personne à pouvoir déchiffrer le fichier en utilisant votre clé privée PGP et votre phrase de passe.

{% hint style="info" %}
En utilisant le [alerte de complétion](/fr/form-management/tasks/task-items/completion-alert.md) vous pouvez recevoir la pièce jointe chiffrée directement dans votre e-mail. 
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/file-upload-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.
