One of the largest HTTPS certificate providers, Let's Encrypt, saw its root certificate expire this week, which means you may need to update your devices to prevent them from breaking.
Let's Encrypt, a free-to-use non-profit organization, issues certificates that encrypt the connections between your devices and the Internet in general, ensuring that no one can intercept and steal your data in transit. Only millions of websites trust Let's Encrypt. But, as security researcher Scott Helme warned, the root certificate Let's Encrypt currently uses, the IdentTrust DST Root CA X3, will expire on September 30. After expiration, computers, devices, and web clients, such as browsers, no longer trusted certificates that have been issued by this certificate authority.
Devices that are likely to be affected by certificate expiration are those that are not updated regularly, such as embedded systems that are designed not to update automatically or smartphones that are running years old versions of software. Users running earlier versions of macOS 2016 and Windows XP (with Service Pack 3) are likely to face issues, along with clients that rely on OpenSSL 1.0.2 or earlier, and older PlayStations that have not been upgraded to older firmware. new.
