Gli sviluppatori del progetto Fedora hanno pianificato la disattivazione del supporto per le firme digitali basate sull'algoritmo SHA-1 in Fedora Linux 39. La disattivazione implica la cessazione della fiducia nelle firme che utilizzano hash SHA-1 (SHA-224 sar\u00e0 dichiarato come il minimo supportato nelle firme digitali), ma manterr\u00e0 il supporto per HMAC con SHA-1 e fornir\u00e0 la possibilit\u00e0 di abilitare il profilo LEGACY con SHA-1. Dopo l'applicazione delle modifiche, la libreria OpenSSL inizier\u00e0 per impostazione predefinita a bloccare la generazione e la verifica delle firme con SHA-1. <\/p>\n

La disabilitazione avverr\u00e0 in pi\u00f9 fasi: In Fedora Linux 36, le firme basate su SHA-1 saranno escluse dalla politica \u00abFUTURE\u00bb, verr\u00e0 fornita una politica di test TEST-FEDORA39 per disabilitare SHA-1 su richiesta dell'utente (update-crypto-policies \u2014set TEST-FEDORA39). Durante la creazione e la verifica delle firme basate su SHA-1, verranno visualizzati avvisi nel registro. Nel processo di preparazione del rilascio di Fedora Linux 38, prima della formazione della beta, nel repository rawhide verr\u00e0 applicata una politica che vieta l'uso di firme basate su SHA-1, ma in beta e nel rilascio di Fedora Linux 38 questa modifica non sar\u00e0 applicata. Nel rilascio di Fedora Linux 39, la politica di cessazione del supporto per le firme basate su SHA-1 sar\u00e0 applicata per impostazione predefinita. <\/p>\n

Il piano proposto non \u00e8 stato ancora esaminato dal comitato FESCo (Fedora Engineering Steering Committee), responsabile della parte tecnica dello sviluppo della distribuzione Fedora. La cessazione del supporto per le firme basate su SHA-1 \u00e8 dovuta al miglioramento dell'efficacia degli attacchi di collisione con prefissi specificati (il costo per trovare una collisione \u00e8 stimato in alcune decine di migliaia di dollari). Nei browser, i certificati firmati utilizzando l'algoritmo SHA-1 sono stati contrassegnati come non protetti sin dalla met\u00e0 del 2016.
