Examine SSL Cert

Need to check when your SSL cert will expire?

openssl s_client -connect $SERVER:$PORT -servername $SERVER 2>/dev/null | openssl x509 -noout -dates
Enter fullscreen mode Exit fullscreen mode

$PORT will likely be 443 - -servername is required if the server is hosting multiple websites.
