GitHub ha aperto una discussione su una proposta per l'implementazione del servizio Sigstore per la verifica dei pacchetti tramite firme digitali e per la gestione di un registro pubblico per confermare l'autenticit\u00e0 nella distribuzione delle release. L'uso di Sigstore permetter\u00e0 di implementare un ulteriore livello di protezione contro attacchi mirati alla sostituzione di componenti software e dipendenze (supply chain). Ad esempio, la modifica implementata protegger\u00e0 i codici sorgente dei progetti in caso di compromissione dell'account di un sviluppatore di una delle dipendenze in NPM e di creazione da parte di un malintenzionato di un aggiornamento del pacchetto con codice malevolo. <\/p>\n
Grazie a un nuovo livello di protezione, gli sviluppatori potranno collegare il pacchetto generato al codice sorgente e all'ambiente di build utilizzati, consentendo all'utente di verificare che il contenuto del pacchetto corrisponda a quello dei file sorgenti nel repository principale del progetto. L'uso di Sigstore semplifica notevolmente il processo di gestione delle chiavi e consente di superare le complessit\u00e0 associate alla registrazione, alla revoca e alla gestione delle chiavi crittografiche. Sigstore \u00e8 presentato come l'equivalente di Let's Encrypt per il codice, fornendo certificati per la certificazione del codice con firme digitali e strumenti per automatizzare la verifica. <\/p>\n
In Sigstore vengono utilizzate chiavi effimere a breve termine invece di chiavi permanenti, generate in base ai diritti d'accesso. Il materiale utilizzato per la firma \u00e8 registrato in un registro pubblico protetto da modifiche, che consente di verificare che l'autore della firma sia effettivamente colui che afferma di essere e che la firma sia stata generata dallo stesso partecipante responsabile delle versioni precedenti. Per garantire l'integrit\u00e0 e proteggere dai cambiamenti retroattivi dei dati, viene utilizzata una struttura ad albero chiamata 'albero di Merkle', in cui ogni ramo verifica tutti i rami e i nodi sottostanti grazie all'hashing congiunto (ad albero). Avendo un hash finale, l'utente pu\u00f2 accertarsi della correttezza dell'intera storia delle operazioni, cos\u00ec come della correttezza degli stati precedenti del database (l'hash di controllo radice del nuovo stato del database viene calcolato tenendo conto dello stato precedente).
