Salut,

**Je cherche à «&nbsp;générer&nbsp;» et/ou «&nbsp;créer manuellement&nbsp;» la liste** «&nbsp;`openssl ciphers`&nbsp;» ci-dessous pour les ajouter/configurer dans **la variable «&nbsp;`SSLCipherSuite`&nbsp;» d’Apache**.

```auto
# https://httpd.apache.org/docs/2.4/fr/ssl/ssl_howto.html
# soyons très tolérant a priori 
SSLCipherSuite ALL:!aNULL:RC4+RSA:+HIGH:+MEDIUM:+LOW:+EXP:+eNULL

```

Exemple de liste d’algorithmes de sécurité SSL/TLS :

Pour vérifier la suite d’algorithmes de sécurité SSL/TLS d’un serveur, en l’occurrence un «&nbsp;site web&nbsp;» sur le port 443 et cela sur son adresse IPv6 :

```auto

La commande ci-dessus permet d’effectuer des tests «&nbsp;seul&nbsp;» pour corriger l’ordre de la suite de chiffrement «&nbsp;Cipher order&nbsp;» de la communication sécurisé entre votre serveur et un client.
