Today we merged a new feature in curl: support for Apple SecTrust. This will become available in curl 8.17.0, due to be released on the 5th of November 2025. What is it and why would you care? Trusting https: connections means a client verifies that the certificates sent by a server are all cryptographic signed correctly. That chain of trust needs to start somewhere with a set of “root” certificates, or more aptly named “trust anchors”.
