Il centro di certificazione non profit Let's Encrypt, controllato 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, la cui durata \u00e8 limitata a 160 ore (6 giorni). Il 13 maggio prevedono di aggiungere il supporto per l'emissione opzionale di certificati con una validit\u00e0 di 45 giorni. Secondo il piano precedentemente annunciato, il 10 febbraio 2027, la durata massima dei certificati sar\u00e0 ridotta da 90 a 64 giorni, mentre il 16 febbraio 2028 sar\u00e0 ridotta a 45 giorni. <\/p>\n

I certificati per indirizzi IP disponibili da oggi sono validi 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 un web server<\/a> tramite indirizzo IP pu\u00f2 essere utile per interagire con dispositivi domestici; durante la configurazione iniziale o il collaudo di nuovi server; per organizzare connessioni crittografate tra backend all'interno dell'infrastruttura; per creare pagine di errore visualizzate quando si accede tramite IP; durante il deploy di server personali; per organizzare l'accesso ai server DoH (DNS over HTTPS) direttamente tramite IP. <\/p>\n

I certificati per i domini, la cui validit\u00e0 \u00e8 limitata a 6 giorni, possono essere utilizzati per aumentare la sicurezza dell'infrastruttura: in caso di una fuga non rilevata del certificato a causa di un attacco, i certificati a vita breve impedirebbero agli attaccanti 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 vita breve per un dominio e un certificato per un indirizzo IP, \u00e8 necessaria la presenza nel client ACME del supporto all'estensione del protocollo che implementa i profili, oltre al supporto del profilo \u00abshortlived\u00bb. Per confermare la propriet\u00e0 dell'indirizzo IP, possono essere utilizzati solo i metodi http-01 e tls-alpn-01 (il metodo dns-01 \u00e8 vietato).
