# Gestion Let's encrypt
## Fonctionnement du service application
Ce service gère le téléchargement et la mise à disposition des certificats Let's encrypt.
Le certificat doit être disponible avant l'installation de la machine de destination.
C'est pourquoi ce le certificat est téléchargement grâce au défi DNS-1.
Il faut donc installer certbot + python3-certbot-dns-xxx (sur une Fedora), par exemple pour OVH "python3-certbot-dns-ovh".
Attention, en utilisant ce service vous acceptez les conditions d'utilisation de Let's Encrypt !
## Utiliser Let's encrypt dans une machine
Dans applicationservice.yml ajouter la dépendance "letsencrypt".
Sur la machine installer Certb
## Configurer Let's encrypt
```
rougail.letsencrypt.domain_names": ["nom de domaine"],
rougail.letsencrypt.authority_cn": {"0": "nom de domaine"},
rougail.letsencrypt.authority_name": {"0": "NomAutorité"},
rougail.letsencrypt.plugin_name": {"0": "ovh"},
rougail.letsencrypt.credential_filename": {"0": "/home/user/ovh.ini"},
rougail.letsencrypt.email": {"0": "gnunux@gnunux.info"}
```
## Exemple avec OVH
Installation du greffon Certbot : https://certbot-dns-ovh.readthedocs.io/en/stable/
Création d'une clef d'API : https://eu.api.ovh.com/createToken/
