title: What is difference between /etc/ssl/certs/ca-bundle.crt and /etc/ssl/certs/ca-bundle.trust.crt in centos7?
body: <p>I am using certificates signed by CA file for securing kubernetes API. For that I added my CA file say ca.crt to <code>/etc/pki/ca-trust/source/anchors/</code> and used the command <code>$ update-ca-trust</code> to add it to the trusted list. I found my certificate in <code>/etc/ssl/certs/ca-bundle.crt</code> file and also in <code>/etc/ssl/certs/ca-bundle.trust.crt</code> file with some appended string of 20 (not exactly) characters. Why there are these two files and what is difference between them ?</p>
