L'autorit\u00e0 certificatrice non profit Let's Encrypt, controllata dalla comunit\u00e0 e che offre certificati gratuitamente a chiunque lo desideri, ha iniziato a rilasciare certificati gratuiti per indirizzi IP, oltre a fornire la possibilit\u00e0 di ottenere certificati TLS con una durata limitata a 160 ore (6 giorni). Il 13 maggio \u00e8 prevista l'aggiunta del supporto per l'emissione opzionale di certificati della durata di 45 giorni. Secondo il piano precedentemente annunciato, il 10 febbraio 2027 il periodo massimo di validit\u00e0 dei certificati sar\u00e0 ridotto da 90 a 64 giorni, e il 16 febbraio 2028 a 45 giorni. <\/p>\n

I certificati per indirizzi IP, disponibili da oggi, vengono emessi per 6 giorni e consentono di configurare l'accesso crittografato sicuro agli host non solo utilizzando nomi di dominio, ma anche accedendo direttamente a indirizzo IP<\/a>. L'accesso protetto a web-server<\/a> tramite indirizzo IP pu\u00f2 essere utile quando si interagisce con dispositivi domestici; durante la configurazione iniziale o il collaudo di nuovi server; per stabilire connessioni crittografate tra backend all'interno dell'infrastruttura; per creare pagine di placeholder visualizzabili accedendo tramite IP; durante il dispiegamento di server personali; per accedere direttamente ai server DoH (DNS over HTTPS) tramite IP. <\/p>\n

I certificati per i domini, la cui validit\u00e0 \u00e8 limitata a 6 giorni, possono essere utilizzati per migliorare la sicurezza dell'infrastruttura: in caso di una perdita inosservata del certificato a causa di un attacco informatico, i certificati a breve termine impediranno agli aggressori di controllare a lungo il traffico della vittima o di utilizzare i certificati per attivit\u00e0 di phishing. <\/p>\n

Per richiedere un certificato a breve termine per un dominio e un certificato per un indirizzo IP \u00e8 necessario il supporto nel client ACME per l'estensione del protocollo che implementa i profili, nonch\u00e9 per il profilo \u00abshortlived\u00bb. Per confermare la propriet\u00e0 di un indirizzo IP possono essere utilizzati solo i metodi http-01 e tls-alpn-01 (il metodo dns-01 \u00e8 vietato).
