verify_pem_cert_key_pair.sh

#!/bin/bash
[[ -z "$1" || -z "$2" ]] && echo "Please specify a certificate and keyfile (in that order)" && exit 1;
diff -sq <(openssl x509 -noout -modulus -in "$1" | openssl md5) <(openssl rsa -noout -modulus -in "$2" | openssl md5) > /dev/null;
[[ $? == 0 ]] && echo "Keys Match" || echo "Keys do NOT Match";
