Den 10 februari 2027 kommer giltighetstiden f\u00f6r certifikat att f\u00f6rkortas till 64 dagar, och den 16 februari 2028 till 45 dagar. En valfri m\u00f6jlighet att f\u00e5 certifikat med en giltighetstid p\u00e5 45 dagar kommer att introduceras den 13 maj 2026.    <\/p>\n<p>Samtidigt kommer giltighetstiden f\u00f6r autentisering gradvis att f\u00f6rkortas - den 10 februari 2027 kommer den att f\u00f6rkortas fr\u00e5n 30 till 10 dagar, och den 16 februari 2028 fr\u00e5n 10 dagar till 7 timmar. Giltighetstiden f\u00f6r autentisering avser tiden efter bekr\u00e4ftelse av r\u00e4ttigheterna till <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sv\/domain\/\"   title=\"dom\u00e4nen\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4103\">dom\u00e4nen<\/a>, under vilken certifikatet kan utf\u00e4rdas utan att beh\u00f6va genomg\u00e5 nya kontroller. Efter att denna tid har l\u00f6pt ut kr\u00e4vs en ny bekr\u00e4ftelse av r\u00e4ttigheterna.       <\/p>\n<p>Som anledning till f\u00f6rkortningen av giltighetstiden f\u00f6r certifikat anges nya krav fr\u00e5n CA\/Browser Forum, som m\u00e5ste f\u00f6ljas av webbl\u00e4sartillverkare och certifikatsmyndigheter. En liknande f\u00f6rkortning av giltighetstiden kommer att inf\u00f6ras av alla certifikatsmyndigheter. CA\/Browser Forum har fastst\u00e4llt slutdatumet f\u00f6r genomf\u00f6randet till mars 2029, och den maximala giltighetstiden f\u00f6r ett certifikat \u00e4r 47 dagar. Efter mars 2029 kommer nya certifikat vars giltighetstid \u00f6verstiger 47 dagar att ge ett felmeddelande \"ERR_CERT_VALIDITY_TOO_LONG\" i webbl\u00e4sarna.    <\/p>\n<p>Bland f\u00f6rdelarna med att \u00f6verg\u00e5 till kortvariga certifikat n\u00e4mns m\u00f6jligheten att minska tiden f\u00f6r implementering av nya kryptovalutor vid identifiering av s\u00e5rbarheter i aktuella protokoll, samt \u00f6kad s\u00e4kerhet. Till exempel, i h\u00e4ndelse av en obem\u00e4rkt l\u00e4cka av certifikatet p\u00e5 grund av ett intr\u00e5ng, kommer kortlivade certifikat att f\u00f6rhindra att angripare l\u00e5ngvarigt kan kontrollera offrets trafik eller anv\u00e4nda certifikatet f\u00f6r phishing. Oftare kontrollering av dom\u00e4ninnehav och kortare giltighetstider f\u00f6r certifikat kommer ocks\u00e5 att minska sannolikheten f\u00f6r att certifikatet forts\u00e4tter vara giltigt efter att informationen i det har blivit irrelevant och minska risken f\u00f6r spridning av felaktigt utf\u00e4rdade certifikat.         <\/p>\n<p>I samband med f\u00f6rkortningen av giltighetstiden f\u00f6r certifikat har Let's Encrypt rekommenderat anv\u00e4ndare att inte uppdatera certifikat manuellt, utan att g\u00e5 \u00f6ver till automatiska certifikatadministrationssystem. Anv\u00e4ndare som redan anv\u00e4nder automatiserade system b\u00f6r se till att deras verktyg korrekt st\u00f6djer certifikat med f\u00f6rkortad giltighetstid. F\u00f6r att koordinera ett snabbt och automatiskt certifikatf\u00f6rnyelse kan administrat\u00f6rer anv\u00e4nda ARI-protokollets till\u00e4gg (ACME Renewal Information), vilket g\u00f6r att de kan f\u00e5 information om n\u00e4r certifikat beh\u00f6ver f\u00f6rnyas och v\u00e4lja optimal tid f\u00f6r f\u00f6rnyelse.
