Den maksimale gyldighedsperiode for TLS-certifikater vil blive reduceret fra 398 dage til 47 dage, medmindre CA\/Browser Forum senere revurderer beslutningen. Udover gyldigheden af certifikaterne er der ogs\u00e5 besluttet at forkorte genbrugstiderne for valideringsdata: for SAN (Subject Alternative Name, hvor \u00e9t certifikat d\u00e6kker flere ressourcer, s\u00e5som at det g\u00e6lder for flere dom\u00e6ner) vil perioden blive forkortet fra 398 til 10 dage, mens den for non-SAN vil blive forkortet fra 825 til 398 dage.    <\/p>\n<p>\u00c6ndringen vil blive implementeret gradvist: fra den 15. marts 2026 vil den maksimale gyldighedsperiode <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/ssl-sertifikat\/\"   title=\"TLS-certifikater\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"954\">TLS-certifikater<\/a> vil blive reduceret til 250 dage fra den 15. marts 2027 \u2014 til 100 dage, og fra marts 2029 \u2014 til 47 dage. Efter hver fase vil behandling af nye certifikater, der ikke overholder de n\u00e6vnte kriterier, f\u00f8re til fejlmeddelelsen \"ERR_CERT_VALIDITY_TOO_LONG\" i browserne. Tidligere har browserproducenterne form\u00e5et at f\u00e5 indf\u00f8rt gradvise reduktioner i certifikaternes levetid fra 8 \u00e5r til 398 dage (13 m\u00e5neder).    <\/p>\n<p>For den nye reduktion af TLS-certifikatets levetid stemte 29 deltagere, 6 undlod at stemme, og ingen stemte imod. Deltagerne, der stemte \"for\": Apple, Google, Microsoft, Mozilla, Amazon, Asseco Data Systems SA (Certum), Buypass AS, Certigna (DHIMYOTIS), Certinomis, DigiCert, Disig, D-TRUST, eMudhra, Fastly, GlobalSign, GoDaddy, HARICA, iTrusChina, Izenpe, NAVER Cloud Trust Services, OISTE Foundation, Sectigo, SHECA, SSL.com, SwissSign, Telia Company, TrustAsia, VikingCloud, Visa. Deltagerne, der undlod at stemme: Entrust, IdenTrust, Japan Registry Services, SECOM Trust Systems, TWCA.      <\/p>\n<p>Det antages, at generering af kortvarige certifikater vil muligg\u00f8re hurtigere implementering af nye kryptografiske algoritmer i tilf\u00e6lde af identifikation af s\u00e5rbarheder i de nuv\u00e6rende, samt reducere sikkerhedstrusler. For eksempel kan kortvarige certifikater forhindre angribere i at kontrollere offerets trafik i lang tid eller bruge certifikater til phishing, hvis der sker en usynlig l\u00e6kage af certifikatet som f\u00f8lge af et brud. Hyppigere validering og forkortelse af certifikatets gyldighed vil ogs\u00e5 mindske sandsynligheden for, at et certifikat forts\u00e6tter med at v\u00e6re gyldigt efter at de informationer, det indeholder, er blevet for\u00e6ldede, og reducere risikoen for distribution af forkert udstedte certifikater.      <\/p>\n<p>Derudover vil kortvarige certifikater fungere som incitament for implementeringen af automatiske certifikatstyringssystemer, der er fri for menneskelige fejl. Dog kan udfasningen af praksis med manuel opdatering af certifikater f\u00f8re til negative konsekvenser. Det bem\u00e6rkes, at nogle enheder, der kun tillader upload af certifikater manuelt, kunne st\u00e5 tilbage med ugyldige certifikater p\u00e5 grund af kompleksiteten ved at organisere manuelle opdateringer hver halvanden m\u00e5ned. \u00c6ndringen kan ogs\u00e5 f\u00e5 negative konsekvenser for certificeringsmyndigheder, der ikke tilbyder API til automatisk modtagelse af certifikater.<br
