Udviklerne af Fedora-projektet har planlagt at deaktivere underst\u00f8ttelsen af digitale signaturer baseret p\u00e5 SHA-1-algoritmen i Fedora Linux 39. Deaktiveringen indeb\u00e6rer, at der ikke l\u00e6ngere vil v\u00e6re tillid til signaturer, der bruger SHA-1-hashes (SHA-224 vil blive erkl\u00e6ret som den minimum underst\u00f8ttede hash i digitale signaturer), men HMAC med SHA-1 vil fortsat blive underst\u00f8ttet, og der vil v\u00e6re mulighed for at aktivere LEGACY-profiler med SHA-1. Efter implementeringen af \u00e6ndringerne vil OpenSSL-biblioteket som standard begynde at blokere generering og validering af signaturer med SHA-1. <\/p>\n

Afbrydelsen planl\u00e6gges at finde sted i flere trin: I Fedora Linux 36 vil underskrifter baseret p\u00e5 SHA-1 blive udelukket fra politikken «FUTURE», en testpolitik TEST-FEDORA39 vil blive givet til deaktivere SHA-1 efter brugernes \u00f8nske (update-crypto-policies —set TEST-FEDORA39), advarsler vil blive vist i loggen ved oprettelse og verifikation af underskrifter baseret p\u00e5 SHA-1. Under forberedelsen af udgivelsen af Fedora Linux 38, f\u00f8r beta-versionen dannes, vil en politik blive anvendt i rawhide-repositoriet, der forbyder brugen af underskrifter baseret p\u00e5 SHA-1, men denne \u00e6ndring vil ikke blive anvendt i beta- og udgivelsen af Fedora Linux 38. I udgivelsen af Fedora Linux 39 vil politikken, der stopper underst\u00f8ttelsen af underskrifter baseret p\u00e5 SHA-1, blive anvendt som standard. <\/p>\n

Den foresl\u00e5ede plan er endnu ikke blevet behandlet af FESCo (Fedora Engineering Steering Committee), som er ansvarlig for den tekniske del af udviklingen af Fedora-distributionen. Oph\u00f8ret af underst\u00f8ttelse for signaturer baseret p\u00e5 SHA-1 skyldes en \u00f8get effektivitet af kollision-angreb med fast pr\u00e6fiks (omkostningerne ved at finde en kollision ansl\u00e5s til flere titusinde dollars). I browsere er certifikater udstedt ved hj\u00e6lp af SHA-1-algoritmen blevet markeret som usikre siden midten af 2016.
