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

#!/usr/bin/perl
# This file was written as an executable to be used in the auto report function
# of csf and lfd. By replacing $YOUR_API_KEY below with your abuseipdb api key,
# allows you to use this code to integrate your csf system with abuseipdb.com
use strict;
use warnings;
use HTTP::Tiny;
use JSON;
# Gather the information from the commandline passed by lfd
