Notre site ne possède pas de domaine, il est en conséquence impossible d’acquérir un certificat correspondant à une ip (sauf 1.1.1.1 apparemment). Le fait que le certificat expire dans 30 jours est demandé. De plus, notre certificat n’est pas trust, ce qui est logique, nous avons notre propre CA, qui n’est pas reconnu en tant qu’ac.

Nous pouvons voir 3 vulnérabilités, nous allons donc les corriger.

En ajoutant gzip off; nous obtenons cela.

La dernière vulnérabilité LUCKY13nous a posé problème, malgré tous nos essais, nous avons toujours eu ce warning.

De façons à réduire le risque, nous avons trouvé des indications concernant des paramètres qui réduisent le risque.
