Le script ci-dessous interroge le psdrive dédié au magasin de certificat local a la machine pour lister les certificats dont la date d’expiration approche (paramètre $expireInDays) et alerter si le nombre de certificats concernés depasse le seuil donné (Paramètre $NbThreshold).
Le parametre $blacklist permet d’exclure les certificats dont l'expiration est considéré OK (root & co, on Windows Server 2003, 2008 & 2012)
