Chiffrement c\u00f4t\u00e9 serveur avec gestion flexible des cl\u00e9s<\/h2>\n

[\/vc_column_text][vc_column_text]Nextcloud prend en charge la gestion des cl\u00e9s de chiffrement modulables. Si vous avez un serveur de cl\u00e9s externe ou un module de s\u00e9curit\u00e9 mat\u00e9riel, ceux-ci peuvent \u00eatre int\u00e9gr\u00e9s \u00e0 Nextcloud.<\/p>\n

Notre gestion par d\u00e9faut des cl\u00e9s de chiffrement permet aux administrateurs de d\u00e9finir une cl\u00e9 de r\u00e9cup\u00e9ration \u00e0 l’\u00e9chelle du syst\u00e8me pour les fichiers chiffr\u00e9s. Cela garantit que, m\u00eame lorsque les utilisateurs perdent leur mot de passe, les fichiers peuvent toujours \u00eatre d\u00e9chiffr\u00e9s. Les fichiers chiffr\u00e9s peuvent \u00eatre partag\u00e9s, mais apr\u00e8s avoir modifi\u00e9 les param\u00e8tres de chiffrement, les partages devront \u00eatre re-partag\u00e9s. En utilisant nos outils en ligne de commande, les donn\u00e9es peuvent \u00eatre chiffr\u00e9es, d\u00e9chiffr\u00e9es ou re-chiffr\u00e9es si n\u00e9cessaire.<\/p>\n

Si vous faites face \u00e0 un besoin r\u00e9glementaire ou de conformit\u00e9 pour chiffrer des donn\u00e9es au repos mais que vous n’avez pas besoin de s\u00e9curiser r\u00e9ellement ces donn\u00e9es, le chiffrement local des donn\u00e9es \u00e0 l’aide de notre gestion des cl\u00e9s int\u00e9gr\u00e9e peut satisfaire aux exigences de conformit\u00e9.[\/vc_column_text][vc_btn title=\u00a0\u00bbEn savoir plus\u00a0\u00bb link=\u00a0\u00bburl:https%3A%2F%2Fdocs.nextcloud.com%2Fserver%2Flatest%2Fadmin_manual%2Fconfiguration_files%2Fencryption_configuration.html|target:_blank\u00a0\u00bb el_class=\u00a0\u00bbbtn-main\u00a0\u00bb][\/vc_column][\/vc_row][\/vc_section][vc_section el_id=\u00a0\u00bbcta-contact\u00a0\u00bb el_class=\u00a0\u00bbcta-contact nc-section-gradient-bg white-text\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1663589051447{padding-top: 3rem !important;padding-bottom: 3rem !important;}\u00a0\u00bb][vc_row content_placement=\u00a0\u00bbmiddle\u00a0\u00bb][vc_column width=\u00a0\u00bb3\/5″ el_class=\u00a0\u00bbtext-right\u00a0\u00bb][vc_column_text el_class=\u00a0\u00bbnc-section-title\u00a0\u00bb]<\/p>\n
