L'autorit\u00e9 de certification \u00e0 but non lucratif Let's Encrypt, contr\u00f4l\u00e9e par la communaut\u00e9 et offrant des certificats gratuitement \u00e0 quiconque le souhaite, a annonc\u00e9 la mise en \u0153uvre du support ARI (ACME Renewal Information) dans son infrastructure. Cette extension du protocole ACME permet de transmettre au client des informations sur la n\u00e9cessit\u00e9 de renouveler les certificats et de recommander le moment optimal pour le renouvellement. La sp\u00e9cification ARI est en cours de standardisation par le comit\u00e9 IETF (Internet Engineering Task Force), qui s'occupe du d\u00e9veloppement des protocoles et de l'architecture d'internet, et est actuellement en phase de relecture de la premi\u00e8re version. <\/p>\n

Avant l'introduction de l'ARI, le client d\u00e9terminait lui-m\u00eame la politique de mise \u00e0 jour des certificats, par exemple en lan\u00e7ant p\u00e9riodiquement le processus de mise \u00e0 jour via Cron ou en prenant des d\u00e9cisions sur la base de l'analyse de la dur\u00e9e de vie des certificats. Une telle approche entra\u00eenait des difficult\u00e9s lorsque des r\u00e9vocations anticip\u00e9es des certificats \u00e9taient n\u00e9cessaires, par exemple, il fallait contacter les utilisateurs par e-mail et les contraindre \u00e0 effectuer une mise \u00e0 jour manuelle. <\/p>\n

L'extension ARI permet au client de d\u00e9finir le moment recommand\u00e9 pour la mise \u00e0 jour du certificat, sans \u00eatre li\u00e9 \u00e0 la dur\u00e9e de vie de 90 jours des certificats, et sans s'inqui\u00e9ter de la possibilit\u00e9 de manquer une r\u00e9vocation impr\u00e9vue du certificat. Par exemple, en cas de r\u00e9vocation anticip\u00e9e via ARI, la mise \u00e0 jour peut \u00eatre initi\u00e9e non pas apr\u00e8s 90 jours, mais apr\u00e8s 60 jours. De plus, l'ARI permet d'att\u00e9nuer efficacement les pics de charge sur serveurs<\/a> Let's Encrypt, choisissant le moment pour le renouvellement en tenant compte de la charge de l'infrastructure.
