Can I retrieve certificate expiry date from an openssl certificate (command line)
 
I'm trying to set up a monitor of our external web sites to warn me of certificate expiry. Can I use openssl to extract the expiry date from the cert or keyring file? The man page doesn't give a lot away...

Found it!

/usr/local/ssl/bin/openssl x509 -noout -in <certificate> -dates
