> A deeper look at post-quantum cryptography support in Red Hat OpenShift 4.20 control plane

The age of quantum computing is on the horizon, and with its immense processing power comes a significant threat to the cryptographic foundations of our digital world. In this article, we'll explore the emerging support for post-quantum cryptography (PQC) in Red Hat OpenShift 4.20, focusing on how it enhances the core components of the Kubernetes control plane: the apiserver, kubelet, scheduler, and controller-manager.
