The deprecation of the AddTrust root certificate has led to failures in systems with OpenSSL and GnuTLS.

Posted on

On May 30, the 20-year validity period of the AddTrust root certificate expired, which was used to create the cross-signed certificates of one of the largest certification authorities, Sectigo (Comodo).

For me, that device is a Chinese laser engraver with a 500mW laser, which is quite unpleasant upon close contact. Besides the direct danger to the eyes, the laser produces toxic combustion products during operation, so the device must be in a well-ventilated […]

I was particularly attracted by the ease of adding a certificate to an application and vhost out of the box, so I decided to migrate my Docker images to Dokku.
