A quick guide for creating self-signed certificates using OpenSSL

Creating a Self-Signed Certificate

Prerequisites

  • You'll need to install OpenSSL to create and sign certificates.
    • Linux: sudo apt-get install openssl
    • MacOS: brew install openssl

cidr to ip range or list. This script prints the ip ranges for a cidr by default. Full ip lists can be obtained with the -a or --all flags.
#!/usr/bin/env bash
# Print usage
function usage {
echo -n "$(basename $0) CIDR...
$(basename $0) [OPTION] CIDR...
This script prints the ip range or full list of ip addresses for one or more CIDR.

How to generate & use private keys using the OpenSSL command line tool

How to Generate & Use Private Keys using OpenSSL's Command Line Tool

These commands generate and use private keys in unencrypted binary (not Base64 “PEM”) PKCS#8 format. The PKCS#8 format is used here because it is the most interoperable format when dealing with software that isn't based on OpenSSL.

OpenSSL has a variety of commands that can be used to operate on private key files, some of which are specific to RSA (e.g. openssl rsa and openssl genrsa) or which have other limitations. Here we always use
