SSL

Autorité de certification

Création de la clé privée

• On se place dans le dossier /etc/ssl/private qui contient les clés et certificats privées :

cd /etc/ssl/private

• On génère la clé privée :

sudo openssl genrsa -out ca.key 2048

Cette clé va nous permettre de signer nos propres certificats.

Création du certificat auto-signé

• On lance la création de certificat auto-signé :

openssl req -new -x509 -nodes -days 365 -key ca.key -out ca.crt You are about to be asked to enter information that will be incorporated into your certificate request.
