Generate new private key and Certificate Signing Request (CSR) for SSL certificates
#!/bin/bash
# ------------------------------------------------------------------------------
# This script will generate a new private key and a Certificate Signing Request
# (CSR) using OpenSSL.
# This script is non-interactive. Instead it uses the variables set at the
# beginning of this script. Alternatively you can adapt this script easily
# to read the values differently as required.
# Developed and tested on Mac OS only, but should work on Linux too.
# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND.
