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 commenc\u00e9 \u00e0 d\u00e9livrer des certificats gratuits pour les adresses IP et a \u00e9galement fourni la possibilit\u00e9 d'obtenir des certificats TLS, dont la dur\u00e9e de vie est limit\u00e9e \u00e0 160 heures (6 jours). Le 13 mai, il est pr\u00e9vu d\u2019ajouter le support de la d\u00e9livrance optionnelle de certificats valables 45 jours. Conform\u00e9ment au plan pr\u00e9c\u00e9demment annonc\u00e9, \u00e0 partir du 10 f\u00e9vrier 2027, la dur\u00e9e maximale de validit\u00e9 des certificats sera r\u00e9duite de 90 \u00e0 64 jours, et le 16 f\u00e9vrier 2028 \u2014 \u00e0 45 jours. <\/p>\n

Les certificats pour adresses IP, disponibles d\u00e8s aujourd'hui, sont valables 6 jours et permettent de configurer un acc\u00e8s s\u00e9curis\u00e9 et chiffr\u00e9 aux h\u00f4tes non seulement en utilisant des noms de domaine, mais aussi en acc\u00e9dant directement \u00e0 une adresse IP<\/a>. L'acc\u00e8s s\u00e9curis\u00e9 \u00e0 un serveur web<\/a> par adresse IP peut \u00eatre utile lors de l'interaction avec des appareils domestiques ; lors de la configuration initiale ou des tests de nouveaux serveurs ; pour \u00e9tablir des connexions chiffr\u00e9es entre les backends dans l'infrastructure interne ; pour cr\u00e9er des pages de substitution affich\u00e9es lors de l'acc\u00e8s par IP ; lors du d\u00e9ploiement de serveurs personnels ; pour organiser l'acc\u00e8s \u00e0 des serveurs DoH (DNS over HTTPS) directement par IP. <\/p>\n

Les certificats pour les domaines, dont la dur\u00e9e de validit\u00e9 est limit\u00e9e \u00e0 6 jours, peuvent \u00eatre utilis\u00e9s pour am\u00e9liorer la s\u00e9curit\u00e9 de l'infrastructure \u2014 en cas de fuite discr\u00e8te du certificat \u00e0 la suite d'un piratage, les certificats de courte dur\u00e9e emp\u00eacheront les attaquants de contr\u00f4ler longtemps le trafic de la victime ou d'utiliser les certificats pour le phishing. <\/p>\n

Pour demander un certificat \u00e0 courte dur\u00e9e de vie pour un domaine et un certificat pour une adresse IP, le client ACME doit supporter l'extension du protocole impl\u00e9mentant les profils, ainsi que le profil \u00ab shortlived \u00bb. Pour prouver la propri\u00e9t\u00e9 d'une adresse IP, seuls les m\u00e9thodes http-01 et tls-alpn-01 peuvent \u00eatre utilis\u00e9es (la m\u00e9thode dns-01 est interdite).
