Le centre de certification \u00e0 but non lucratif Let's Encrypt, g\u00e9r\u00e9 par la communaut\u00e9 et offrant des certificats gratuitement \u00e0 tous ceux qui le souhaitent, a averti de la r\u00e9duction de la dur\u00e9e de validit\u00e9 des certificats TLS de 90 \u00e0 64 jours. \u00c0 partir du 10 f\u00e9vrier 2027, tous les nouveaux certificats et ceux renouvel\u00e9s seront \u00e9mis pour une dur\u00e9e de 64 jours, tandis que les certificats \u00e0 90 jours \u00e9mis avant cette date continueront d'\u00eatre valides. De plus, \u00e0 partir du 10 f\u00e9vrier 2027, la p\u00e9riode d'autorisation sera r\u00e9duite de 30 \u00e0 10 jours, c'est-\u00e0-dire le temps apr\u00e8s la confirmation de vos droits sur le domaine, pendant lequel un certificat peut \u00eatre \u00e9mis sans passer de nouvelles v\u00e9rifications. \u00c0 partir du 16 f\u00e9vrier 2028, la dur\u00e9e de validit\u00e9 des certificats sera r\u00e9duite de 64 \u00e0 45 jours, et celle des autorisations - de 10 jours \u00e0 7 heures.<\/p>\n
La raison de cette r\u00e9duction de la dur\u00e9e de validit\u00e9 des certificats est due aux nouvelles exigences de l'association CA\/Browser Forum, \u00e9labor\u00e9es lors des travaux conjoints des fabricants de navigateurs et des centres de certification. Une r\u00e9duction similaire de la dur\u00e9e de validit\u00e9 sera mise en \u0153uvre par tous les centres de certification. Le CA\/Browser Forum a fix\u00e9 la date limite de mise en \u0153uvre \u00e0 mars 2029, avec une dur\u00e9e maximale de validit\u00e9 des certificats de 47 jours. Apr\u00e8s mars 2029, le traitement dans les navigateurs des nouveaux certificats, dont la dur\u00e9e de validit\u00e9 d\u00e9passe 47 jours, entra\u00eenera des erreurs intitul\u00e9es \u00ab ERR_CERT_VALIDITY_TOO_LONG \u00bb.<\/p>\n
Le passage \u00e0 des certificats \u00e0 courte dur\u00e9e de validit\u00e9 r\u00e9duira le temps de mise en \u0153uvre de nouveaux algorithmes cryptographiques en cas de d\u00e9couverte de vuln\u00e9rabilit\u00e9s et emp\u00eachera les attaquants de contr\u00f4ler la circulation du trafic de la victime pendant longtemps ou d'utiliser des certificats pour le phishing en cas de fuite de certificat r\u00e9sultant d'un piratage. Une v\u00e9rification plus fr\u00e9quente de la propri\u00e9t\u00e9 le domaine<\/a> et la r\u00e9duction des dur\u00e9es de validit\u00e9 des certificats diminueront \u00e9galement la probabilit\u00e9 que le certificat continue \u00e0 \u00eatre valide apr\u00e8s que les informations qu'il contient ne soient plus \u00e0 jour, r\u00e9duisant ainsi le risque de distribution de certificats mal d\u00e9livr\u00e9s. \u041d\u0435\u043a\u043e\u043c\u043c\u0435\u0440\u0447\u0435\u0441\u043a\u0438\u0439 \u0443\u0434\u043e\u0441\u0442\u043e\u0432\u0435\u0440\u044f\u044e\u0449\u0438\u0439
