Subj : 10 Years of Let's Encrypt Certificates To : All From : LWN.net Date : Thu Dec 11 2025 06:40:07 Let's Encrypt has published a retrospective that covers the decade since it published its first publicly trusted certificate in September 2015: In March 2016, we issued our one millionth certificate. Just two years later, in September 2018, we were issuing a million certificates every day. In 2020 we reached a billion total certificates issued and as of late 2025 we're frequently issuing ten million certificates per day. We're now on track to reach a billion active sites, probably sometime in the coming year. https://lwn.net/Articles/1049965/ --- SBBSecho 3.32-Linux * Origin: Palantir * palantirbbs.ddns.net * Pensacola, FL * (86:200/23) .
