SSL:Correlate PEM and KEY Files

Correlating PEMs and Keys

You should have labelled your SSL .pem and .key files, but you didn't. Associate them with the power of math! If the checksums align between a key and PEM, they are a pair.

for f in $(ls | egrep -i "pem|key"); 
do
    printf $(openssl rsa -modulus -noout -in "$f" 2>/dev/null | openssl md5 | awk '{ print $NF }')"\t$f\n";
    printf $(openssl x509 -modulus -noout -in "$f" 2>/dev/null | openssl md5 | awk '{ print $NF }')"\t$f\n"; 
done | sort -k1 | grep -vi \.csr
