Expiration of the IdenTrust DST Root CA X3 digital certificate

On September 30, 2021, the IdenTrust DST Root CA X3 encryption certificate has expired. This certificate was used to encrypt data exchange between websites and devices. So various devices have already faced issues with accessing particular sites with HTTPS-encryption. You might also experienced such issues, and that is the reason why you’re here.

The expiration of the IdenTrust DST Root CA X3 HTTPS root certificate may cause problems with access to websites and online services on outdated smartphones and computers – such as iPhones and iPads with OS under iOS 10, MacBooks with macOS 10.12.0 and earlier, smartphones with OS Android 2.3.6 and previous OSes, computers with Windows XP Service Pack 2, ATMs, PlayStation consoles and other devices with outdated OSes without proper updates.

IdenTrust DST Root CA X3 digital certificate had been released by Let’s Encrypt company and its expiration date was marked on September 30, 2021. All devices that didn’t get necessary updates and therefore didn’t “know” about the updated version of the certificate, experienced problems with connection to various websites using the encrypted HTTPS protocol after the certificate has expired.

In order to fix this issue, you can update your OS or install proper updates on your OS. Also, you can replace the outdated certificate with ISRG Root X1 that will be working until 2035.

It is difficult to say how noticeable the problems will be due to the expired Let’s Encrypt certificate. Something somewhere is definitely going to break.
