A root certificate is invaluable, because any certificate signed with its private key will be automatically trusted by the browsers. Ergo, you really need to make sure you can trust the Certificate Authority issuing from it. if you use openssl for certificate creation for instance the extended key usage is set to CA:FALSE aka this

This behavior appears to be fixed in Red Hat Enterprise Linux 8 (OpenSSL 1.1.1c FIPS) and Ubuntu 14.04 (OpenSSL 1.1.1) as the same clock advancing tests resulted in successful connections and OpenSSL validating properly OpenSSL OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library. For more information about the team and community around the project, or to start making your own contributions, start with the community page.
The Difference Between Root Certificates and Intermediate
It can be used as a basis to expand the certificate deployment into other applications. This document assumes you are using the Zscaler Intermediate certificate for TLS / SSL Inspection – if you are using a custom certificate for TLS / SSL Inspection, then you should replace all references to Zscaler Root with your custom Root certificate.

How to setup your own CA with OpenSSL · GitHub I am trying to implement a functional root CA and based on your post, does it means that after generating a new asymmetric key pair, I am able to immediately generate a self-signed root certificate through this command "$ openssl req -new -x509 -key ca.key -out ca.crt" without having to generate a CSR?
