Creating and Installing a Self-Signed TLS Certificate and CA

This article demonstrates how to create a self-signed TLS certificate and Certificate Authority (CA) on a Linux system and install it to address the issue of browsers not trusting self-signed certificates. It details the steps for generating private keys, certificate signing requests, signing certificates, and installing the CA certificate on Ubuntu and Arch Linux systems. Instructions for importing the CA certificate into Firefox and Chromium browsers are also included. By creating your own CA and adding it to the trusted CA list, man-in-the-middle attacks can be effectively avoided, ensuring the security of your private network.
