# Certificate Authority # Setting up a Certificate Authority and TLS Cert Generation
In this lab you will setup the necessary PKI infrastructure to secure the Kuberentes components. This lab will leverage CloudFlare's PKI toolkit, [cfssl](https://github.com/cloudflare/cfssl), to bootstrap a Certificate Authority and generate TLS certificates. In this lab you will setup the necessary PKI infrastructure to secure the Kuberentes components. This lab will leverage CloudFlare's PKI toolkit, [cfssl](https://github.com/cloudflare/cfssl), to bootstrap a Certificate Authority and generate TLS certificates.
This lab will setup a Certificate Authority and generated a single set of TLS certificates that can be used to secure the following Kubernetes components:
* etcd
* Kubernetes API Server
* Kubernetes Kubelet
In production you should strongly consider generating individual TLS certificates for each component.
