SSL certificate expiration

written by peter, on Apr 24, 2006 8:37:00 AM.

A simple oneliner that I’ve had to look up three times now, so I’m blogging it:

openssl s_client -connect secure.gay.nl:443 | 
   openssl x509 -noout -dates

thx, I know this will come in handy one day :)

I wrote a shell script to automate this, and posted it here: http://daemons.net/~matty/articles/checkcertificate.html In addition to printing expiration data, it can be configured toe-mail you prior to a certificate expiring. - Ryan
