Based on some feedback I received through email, I modified the ssl-cert-check “-f” option to allow it to process files in addition to hosts/ports:
$ cat ssldomains
prefetch.net 443
gmail.google.com 443
www.sun.com 443
/etc/ca/cacert.pem FILE
$ ssl-cert-check -f ssldomains
Host Status Expires Days Left
----------------------------------------------- ------------ ------------ ----------
prefetch.net:443 Valid May 23 2006 51
gmail.google.com:443 Valid Jun 7 2006 66
www.sun.com:443 Valid Dec 1 2007 608
FILE:/etc/ca/cacert.pem Valid Jan 2 2008 640
Hopefully folks find this useful.
