Script I used to generate an SSL key and sign a certificate for using with a grunt development server.

generate-certs.sh

#!/bin/bash

root_dir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
ssl_dir=$root_dir/ssl

mkdir -p $root_dir/ssl

echo ">> Generating SSL key and certificate..."
rm -rf $ssl_dir/*

pushd $ssl_dir > /dev/null
openssl genrsa -out privatekey.pem 1024
openssl req -new -key privatekey.pem -out certrequest.csr 
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem
popd > /dev/null

echo
echo 'done!'
