Comment puis-je modifier un certificat auto-signé créé à l'aide d'openssl xampp?

Cependant, je souhaite modifier le nom commun, est-ce possible? Personne ne sait comment je peut remplacer le certificat?

Ce n'est pas possible soi. Le Nom Commun (CN) est dans la partie du certificat qui est signé, de sorte que vous ne pouvez pas simplement le supprimer sans invalider la signature.

Cependant, vous pouvez tout simplement de générer une nouvelle demande de certificat ou de certificats auto-signés avec des noms DNS dans l'autre Nom d'Objet (SAN) (et pas dans le Nom Commun (CN)).

L'astuce pour la création d'un certificat auto-signé avec des noms DNS dans le SAN est que vous devez utiliser un fichier de configuration personnalisé. Vous ne pouvez pas générer un en utilisant la ligne de commande, car les noms DNS dans les SAN sont pas copié. Ci-dessous est la coutume fichier CONF que j'utilise (appelé example-com.conf).

#     openssl req -config example-com.conf -new -x509 -sha256 -newkey rsa:2048 -nodes -keyout example-com.key.pem -days 365 -out example-com.cert.pem
# Signing Request (note the lack of -x509):
#     openssl req -config example-com.conf -new -newkey rsa:2048 -nodes -keyout example-com.key.pem -days 365 -out example-com.req.pem
# Print it:
