I have got a lot of domains. I use basic monitoring script, which checks expiration date of ssl certificate. But a few of my domains use default cloudflare cert.
How to determine and reject domains which use cloudflare built-in SSL certificate?
You could just make a simple bash script like:
#!/bin/bash x=$(openssl x509 -in cert.pem -text | grep -i cloudflare) if [ "$x" != "" ]; then # code for rejecting else # code for ok fi
