Contexte<\/h2>\n

Les certificats authentifient et chiffrent les donn\u00e9es afin de garantir la s\u00e9curit\u00e9 des communications sur les r\u00e9seaux. Au fil du temps, les certificats peuvent devenir invalides, expirer ou \u00eatre compromis, ce qui n\u00e9cessite leur suppression. Les professionnels de l’informatique et les MSP ont souvent besoin d’une m\u00e9thode fiable pour localiser et g\u00e9rer efficacement ces certificats. Ce script PowerShell fournit une solution robuste pour trouver et g\u00e9rer les certificats par empreinte, garantissant ainsi la s\u00e9curit\u00e9 et la conformit\u00e9 des syst\u00e8mes.<\/p>\n
