<p>C’est un bon rappel que <a href="https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/">HTTPS crée de l’obsolescence</a> (<a href="/david/cache/2021/372cdbf3dc67c7796673bec4aaeb9f0f/">cache</a>) en ne supportant plus des périphériques plus anciens (au même titre qu’un système d’exploitation par exemple). La durée acceptable semble être de 10&nbsp;ans dans le cas du compromis qui a été fait. Les personnes détentrices (<a href="https://letsencrypt.org/docs/certificate-compatibility/">entre beaucoup d’autres</a>) d’un iPhone 4&nbsp;ne pourront plus accéder à cet espace — et des millions d’autres — d’ici la fin de l’année et ça me rend triste.</p>
