Den non-profit certifikationsmyndighed Let's Encrypt, som kontrolleres af f\u00e6llesskabet og gratis tilbyder certifikater til alle interesserede, har annonceret en gradvis reduktion af gyldigheden af de udstedte TLS-certifikater fra 90 til 45 dage. Den 10. februar 2027 vil gyldigheden af certifikaterne blive reduceret til 64 dage, og den 16. februar 2028 \u2014 til 45 dage. Muligheden for at f\u00e5 certifikater, der er gyldige i 45 dage, vil blive tilg\u00e6ngelig den 13. maj 2026. <\/p>\n

Samtidig vil gyldigheden af autorisationen gradvist blive reduceret \u2014 den 10. februar 2027 vil den blive reduceret fra 30 til 10 dage, og den 16. februar 2028 \u2014 fra 10 dage til 7 timer. Med gyldigheden af autorisationen forst\u00e5s tiden efter bekr\u00e6ftelsen af ens rettigheder til dom\u00e6ne<\/a>, i hvilken periode certifikatet kan udstedes uden gentagne kontroller. Efter udl\u00f8bet af denne tid kr\u00e6ves der en ny bekr\u00e6ftelse af rettighederne. <\/p>\n

Som \u00e5rsag til reduktionen af gyldigheden af certifikaterne n\u00e6vnes nye krav fra CA\/Browser Forum, som browserproducenter og certifikationsmyndigheder skal f\u00f8lge. En tilsvarende reduktion i gyldigheden vil blive implementeret af alle certifikationsmyndigheder. CA\/Browser Forum har fastsat en frist for gennemf\u00f8relsen til marts 2029, og den maksimale gyldighed for et certifikat vil v\u00e6re 47 dage. Efter marts 2029 vil behandling af nye certifikater, hvis gyldighed overstiger 47 dage, resultere i fejlmeddelelsen \u2018ERR_CERT_VALIDITY_TOO_LONG\u2019. <\/p>\n

Blandt fordelene ved at overg\u00e5 til kortvarige certifikater n\u00e6vnes muligheden for hurtigere implementering af nye kryptografiske algoritmer i tilf\u00e6lde af opdagelse af s\u00e5rbarheder i de nuv\u00e6rende, samt \u00f8get sikkerhed. For eksempel, hvis et certifikat utilsigtet l\u00e6kkes som f\u00f8lge af et hack, vil korttidscertifikater forhindre angrebere i at opretholde kontrol over offerets trafik i lang tid eller bruge certifikater til phishing. Hyppigere kontrol af dom\u00e6neejerskab og reducerede gyldighedsperioder for certifikater vil ogs\u00e5 mindske risikoen for, at et certifikat forts\u00e6tter med at v\u00e6re gyldigt efter at oplysningerne i det er blevet for\u00e6ldede, samt reducere risikoen for spredning af fejlagtigt udstedte certifikater. <\/p>\n

I forbindelse med den forkortede gyldighed af certifikaterne har Let's Encrypt anbefalet brugerne ikke at opdatere certifikater manuelt, men at skifte til automatiske certifikatadministrationssystemer. Brugere, der allerede anvender automatiserede systemer, skal sikre sig, at deres v\u00e6rkt\u00f8jer korrekt underst\u00f8tter certifikater med forkortet gyldighed. For at koordinere en rettidig automatisk opdatering af certifikaterne kan administratorer bruge udvidelsen af protokollen ARI (ACME Renewal Information), som g\u00f8r det muligt at modtage oplysninger om behovet for opdatering af certifikaterne og v\u00e6lge det optimale tidspunkt for opdateringen. Det giver ogs\u00e5 mening at ops\u00e6tte et overv\u00e5gningssystem for at identificere situationer, hvor certifikatet ikke er blevet opdateret i tide. <\/p>\n

For easier domain ownership verification, the Let’s Encrypt project plans to implement a new DNS-PERSIST-01 verification method in 2026, which, unlike the HTTP-01 and DNS-01 methods, does not require updating information with each check or access by the ACME client to web infrastructure or DNS servers. In PERSIST-01, it is sufficient to add a specific TXT record to the DNS once (‘_validation-persist.example.com. IN TXT («ca.example;» » accounturi=https:\/\/ca.example\/acct\/123″)’), and the ACME client will be able to perform authorization without updating data in the DNS.
