On créer un répertoire qui contiendra les certificats dans /var/certs :
root@host:~# cd /var/; mkdir certs; cd certs/; mkdir v01; cd v01/
NB : C'est le fichier /usr/lib/ssl/openssl.cnf qui permet de pré-remplir les infos du certificat (Country Name, State Or Privince etc...).
On créer son autorité de certification grâce au script /usr/lib/ssl/misc/CA.pl :
root@host:~# /usr/lib/ssl/misc/CA.pl -newca
